3.2.3	Detailed changes for 3.2.3
	Bugfix release only. No new features.
	- Fixed a bug in the http control code that failed to accept a client
	connecting in some systems (Peter Holik).
	- Fixed a series of bugs where several feature were using the image buffer
	after text was added for noise tuning, auto_brightness, reference frame
	update when tracking etc. When a netcam failed to produce an image the
	text added to the previous image became motion detected also. The code is
	not changed so that the ring buffer is used for timestamped images
	and the image used for detection is in a buffer cnt->imgs.image_virgin.
	(Kenneth Lavrsen).
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x08x15x140701
	- Auto brightness used the first image in ring buffer instead of the
	latest image and it used an image with time stamping. It now uses the new
	cnt->imgs.image_virgin buffer.
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x08x15x160208
	- Cleaned out unused code from httpd control (Angel Carpintero).
	- Option switch filter used print_int instead of print_bool when motion.conf
	was saved (Kenneth Lavrsen).
	

3.2.2	Formal Release. Summary of changes

Features
	- New completely rewritten netcam code.
	- Proxy servers are again supported by netcam feature
	- New conversion specifier %o for threshold
	- New convertion specifier %Q for number of labels
	- Drawing of mask and smartmask in setup mode improved
	- Compilation of motion on 64 bit machines improved
	- RPMs can now be built by non-root user
	- Improved the labelling algoritm so that locate feature and tracking features
	includes all labelled areas above threshold	
	- Motion now supports the mjpeg webcam stream while saving PPM images.
	- New improved webcam feature. When you set webcam_motion on Motion will now
	stream at 1 fps instead of none. When motion is detected the webcam stream
	increases to the limit set in the config file. This change makes the
	webcam_motion much more interesting. The previous function always ended up
	with clients timing out.
	- Implemented the libjpeg-mmx patch. Installing the MMX version of libjpeg
	can increase performance. Especially for machines with very little CPU power.
	It only modifies the configure script. If you do not have the libjpeg-mmx
	the configure script with ignore this and use the standard libjpeg.
	Note that RPMS will be built without this
	- Improved descriptions in motion.conf
	- Many small code speed optimizations.
	- Added new feature: Double size text. A new config option 'text_double' can
	be set 'on' and this scales the text to double size. Default is off.
	- Improved error handling of missing picture frames from camera. Especially
	network cameras will often not be able to provide a picture frame from time
	to time. Motion would retry before and eventually and rather quickly exit
	the camera thread and maybe completely exit. The improved handling now
	makes a copy of the previous frame for 30 seconds (longer if cpu_low is
	activated because the implementation is 30 X framerate frames) and then
	show a grey image with a message saying the connection is lost and an ISO
	format time stamp of first poor connection.
	- Added a configure option --with-developer-flags which enables many compiler
	warnings that can be used by developers to make code more robust. Not
	for normal users building Motion.
	- Included a CODE_STANDARD text file to help new developers make patches
	that are easier to integrate without too much manual editing.
	
Bug Fixes
	- Fixed a bug in the autobrightness algoritm
	- Fixed bug reporting errors when creating symlink to last snap
	- Improved code so that Motion no longer uses the tmpfile() function for
	buffering the frames of the mjpeg stream.
	- Implemented a fix/work around to a bug related to building and installing
	RPMs on Suse.
	- Improved signal handler
	- Code commented much more.
	- Many bugfixes to get Motion more stable (less seg faults)
	- Code improved to remove all warnings when compiled with gcc 4.0
	- Better FreeBSD support
	- Replace functions not threadsafe with threadsafe functions.
	- Implemented a much easier to use motion_log function which replaces the
	calls to prinf and syslog. This code change as no impact to the user.
	- Fixed a bug in video.c so that VIDEO_PALETTE_GREY cameras now actually work.
	- Updated the ffmpeg.c code so that Motion can now be built with ffmpeg CVS
	release from the June/July 2005 timeframe.



3.2.2	Detailed changes for 3.2.2
snap1	- Pthread deadlock in motion 3.2.1 fixed (Angel Carpintero)
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x26x125712
	- http lockup bugfixes and ConvertSignalToSigaction only for webhttpd
	(Angel Carpintero)
	- alg_draw_location: Use temporary variables to store the values used in
	for() loops instead of compute them in each loop (Angel Carpintero).
	http://www.lavrsen.dk/twiki/bin/view/Motion/ImproveAlgDrawLocation
	- Small speed boost to the function draw_textn (Andrew Hamilton and
	Angel Carpintero).
	http://www.lavrsen.dk/twiki/bin/view/Motion/DrawTextnImprovement
	- Added two new convertion specifiers: %o for threshold and %Q for number
	of labels. (Kenneth Lavrsen)
	- Improved the config file description for pre_capture to get people to
	use small values (Kenneth Lavrsen).
	
snap2	- Avoid Cleanup Segfault. Avoid Cleanup Segfault. Allocates filepath using
	strdup to avoid segfault is target_dir parameter is not supplied in
	motion.conf. Moves out from signal handler the cleanup for pipe and mpipe.
	(Angel Carpintero)
	http://www.lavrsen.dk/twiki/bin/view/Motion/AvoidCleanupSegfault
	- Major code cleanup concerning signedness of chars all over the code to
	allow compilation with gcc4.0 (like in Fedora Core 4) without any
	errors or warnings. This will probably require that some of the not yet
	included patches will have to be fixed because it it code all over the
	place that has been changed. (Kenneth Lavrsen)
	
snap3	- Changed the order of drawing the red mask in setup mode so that the
	smartmask is drawn after the fixed mask (Joerg Weber).
	- Changed the configure script so that /usr/lib64 is also searched for
	the presense of ffmpeg (should fix the problem with 64 bit machines)
	(Kenneth Lavrsen).
	- Changed the configure script so that rpms can be made by normal non-root
	users (Angel Carpintero, Kenneth Lavrsen).
	
snap4	- Fixed the ffmpeg code so that Motion also compiles against libavcodec
	build 4754 or later. (Per Jnsson)
	- Above change in configure script for 64 bit ffmpeg support also implemented
	in the freeBSD configure (Angel Carpintero)
	- Webhttp control interface fixed so it also works in FreeBSD (Angel
	Carpintero)
	- Improved the display of fixed mask. It is now shown as grey instead of
	red. This makes it easier to see the smart mask working when you also have
	a fixed mask (Joerg Weber).
	- Netcam First Header patch. If an error with jpeg decompression occured at
	connecting to a mjpeg streaming webcam, this patch skips this jpeg and tries
	to decompress next jpeg up to MAX_HEADER_RETRIES (20) (Peter Holik).
	http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamFirstHeader
	
snap5	- Small improvement in framerate accuracy (Peter Holik).
	http://www.lavrsen.dk/twiki/bin/view/Motion/FramerateAdjust
	- Fixed a bug in the autobrightness algoritm (Per Johnsson)
	- Fixed a bug in the webhttpd code related to pan/tilt. Bug was introduced in
	snap4 (Angel Carpintero, Kenneth Lavrsen).
	- Improved the labelling algoritm so that locate feature and tracking features
	includes all labelled areas above threshold (Joerg Weber).
	http://www.lavrsen.dk/twiki/bin/view/Motion/ImprovedLabellingPatch
	- Fixed bug reporting errors when creating symlink to last snap (Bill Maidment)
	- Changed all use of localtime to localtime_r which is threadsafe
	(Kenneth Lavrsen).
	- Implemented a modified version of the WebcamCompressInMemory so that Motion
	no longer uses the tmpfile() function for buffering the frames of the mjpeg
	stream (Peter Holik).
	http://www.lavrsen.dk/twiki/bin/view/Motion/WebcamCompressInMemory
	- Modified the WebcamCompressInMemory patch so that Motion now supports the
	mjpeg webcam stream while being setup for saving PPM images (Kenneth Lavrsen).
	http://www.lavrsen.dk/twiki/bin/view/Motion/WebcamCompressInMemory
	- Major clean-up of code in picture.c and webcam.c so that function names and
	variable names are less confusing. Also added many comments in picture.c.
	(Kenneth Lavrsen).
	
snap6	- Webcam code commented more (Kenneth Lavrsen)
	- New improved webcam feature. When you set webcam_motion on Motion will now
	stream at 1 fps instead of none. When motion is detected the webcam stream
	increases to the limit set in the config file. This change makes the
	webcam_motion much more interesting. The previous function always ended up
	with clients timing out. (Kenneth Lavrsen).

snap7	- Implemented WebcamShortWriteHandling patch (Bill Brack)
	http://www.lavrsen.dk/twiki/bin/view/Motion/WebcamShortWriteHandlingPatch
	- Implemented the libjpeg-mmx patch. Installing the MMX version of libjpeg
	can increase performance. Especially for machines with very little CPU power.
	It only modifies the configure script. If you do not have the libjpeg-mmx
	the configure script with ignore this and use the standard libjpeg.
	Note that RPMS will be built without this (Peter Holik and Angel Carpintero).
	http://www.lavrsen.dk/twiki/bin/view/Motion/LibJpegMmx

snap8	- Small code cleanup in webcam.c and picture.c and .h for the webcam code
	(Peter Holik and Kenneth Lavrsen)
	- Small code cleanup in motion.c for the variable holding the number of
	microseconds since epoch. The old code worked fine but relied on an integer
	overflow every 71 minutes. (Bill Brack and Kenneth Lavrsen)
	- Implemented a fix/work around to a bug related to building and installing
	RPMs on Suse. (Paul Beltrani)
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x07x14x212356
	- Small speed optimization in the creation of reference frame (Peter Holik).
	- Complete rewrite of the Netcam code. Should fix many of the reported and
	still open netcam bugs. This is first release in a snapshot. Expect to find
	bugs. Testing is important. If you have a netcam please test this and report
	bugs.
	http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamCodeRewritePatch
	
snap9	- Fixed bug related to disabled webcam or duplicate webcam port. Error log
	accept(): Socket operation on non-socket continuously written to syslog.
	(Kenneth Lavrsen)
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x08x01x150922
	- Fixed memory leak in webhttpd related to use of strdup (Angel Carpintero).
	- Improved the error reporting in the Netcam code and did a few minor
	corrections and code cleansups (Bill Brack).
	- Implemented a much easier to use motion_log function which replaces the
	calls to prinf and syslog. The implementation to actually use this has been
	implemented in video.c and the Netcam code files. Rest will be in next snap.
	This code change as no impact to the user (Bill Brack).
	http://www.lavrsen.dk/twiki/bin/view/Motion/ErrorLoggingEnhancementPatch
	- Fixed a bug in video.c so that VIDEO_PALETTE_GREY cameras now actually work
	(Bill Brack).
	- Implemented the conversion of signal to sigaction which should be more
	thread safe. Hopefully this still keeps Motion from making Zombies.
	(Christophe Grenier).
	http://www.lavrsen.dk/twiki/bin/view/Motion/ConvertSignalToSigaction
	- Added new feature: Double size text. A new config option 'text_double' can
	be set 'on' and this scales the text to double size. Default is off.
	(Andrew Hamilton).
	http://www.lavrsen.dk/twiki/bin/view/Motion/TextScalingPatch
	
snap10	- Error Logging Enhancement Patch v 1.3 (Angel Carpintero) including:
	   - Populate the motion_log to the whole motion source code. 
	   - Fixed FreeBSD copilation. 
	   - Added the posiblity to pass NULL as struct context * 
	   - Removed unused errno variables. 
	   - Fixed errno in rotate.c , set to 0. 
	   - Fixed some errno flags in webhttpd.c and motion.c 
	   - Fixed a bug when not motion.conf is found 
	   - Removed printf from all files 
	   - Fixed the conf_list[] index in motion.c 
	http://www.lavrsen.dk/twiki/bin/view/Motion/ErrorLoggingEnhancementPatch
	- RotateBswapFix Patch v 2 (Per Jnsson) including:
	   - cleanup in code comments
	   - fix for __bswap_32 macro collision
	   - fixed bug where initialization would be incomplete for invalid degrees
	     of rotation
	   - now uses motion_log for error reporting 
	http://www.lavrsen.dk/twiki/bin/view/Motion/RotateBswapFix
	- Re-mplementation of optional Proxy Server for Network Cameras (Bill Brack).
	http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamProxyServerPatch
	- Included a CODE_STANDARD text file to help new developers make patches
	that are easier to integrate without too much manual editing. (Kenneth
	Lavrsen)
	- Added the missing rotate feature in the new netcam code (Bill Brack)

snap11	- Updated the ffmpeg.c code so that Motion can now be built with ffmpeg CVS
	release from the June/July 2005 timeframe (Per Jnsson).
	http://www.lavrsen.dk/twiki/bin/view/Motion/FfmpegCodecPatch
	- Improved error handling of missing picture frames from camera. Especially
	network cameras will often not be able to provide a picture frame from time
	to time. Motion would retry before and eventually and rather quickly exit
	the camera thread and maybe completely exit. The improved handling now
	makes a copy of the previous frame for 5 seconds (longer if cpu_low is
	activated because the implementation is 5 X framerate frames) and then
	show a grey image with a message saying the connection is lost and an ISO
	format time stamp of first poor connection. (Kenneth Lavrsen).
	- Implemented version 2 of the NetcamErrorImprovementPatch which should
	work with the improved error handler. Changes include:
	   - Changes handling of non-streaming camera to include a separate thread. 
	   - Changes the value returned from netcam_next to the motion main loop to
	     indicate the status of the image returned. 
	   - Many changes to the comments, and some enhancement to the logic, to begin
	     the implementation of points agreed on the NetcamRetryErrorDiscussion page. 
	   - Implements the triple-buffering scheme proposed by PeterHolik (but not the
	   "Without Locking" portion of his proposal).
	Version 2 however does not seems to recover when an mjpeg stream resumes
	after a period of not being available. (Bill Brack)
	http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamErrorImprovementPatch
	- Note: Snap11 release as a developer sync release. Bug reports welcome.
	FreeBSD code changes not tested yet.
	
Release	- Netcam error handling improvements and cleanup from Walgrind analysis
	(Bill Brack).
	- Added a configure option --with-developer-flags which enables many compiler
	warnings that can be used by developers to make code more robust. Not
	for normal users building Motion (Bill Brack)
	- http-control: Fixed segfault when motion is restarted from command line
	( kill -s 1 pid_motion ). Improved control code so Motion can Restart and
	Finish 'smoothly'. (Angel Carpintero).
	http://www.lavrsen.dk/twiki/bin/view/Motion/MotionHttpControl
	- Changed the 5 second missed camera signal timeout to 30 seconds. (Kenneth
	Lavrsen)
	- Fixed bug where an extra jpeg is saved if you have output_normal=best
	and you stop motion after an event has ended. (Kenneth Lavrsen)
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x08x05x173526

	

3.2.1	Detailed changes for 3.2.1 since 3.1.19_snap3
snap1	- Major new feature. XMLRPC is replaced by a simpler http remote control
	interface (implemented by Angel Carpintero)
	http://www.lavrsen.dk/twiki/bin/view/Motion/MotionHttpControl

snap2	- Fixed netcam->userpass problem (Angel Carpintero)
	- Added support in configure for athlon64 from
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x30x190907
	(Angel Carpintero and William M Brack) 
	- Fixed some gcc warnings (William M Brack) 
	- Code cleanup from a valgrind analysis (William M. Brack).

snap3	- Added Best Preview Patch (Joerg Weber)
	http://www.lavrsen.dk/twiki/bin/view/Motion/BestPreviewShot
	
snap4	- Fix for tracking control with http control (Angel Carpintero)
	- Added the new feature Setup Mode (Joerg Weber). This also enables
	much more error messages given to the console when in non-daemon mode
	while still preserving the messages in syslog which are important
	for daemon mode debugging.
	The patch is still being worked on and is not finished.
	Changes in the FreeBSD code are not yet tested.
	http://www.lavrsen.dk/twiki/bin/view/Motion/SetupModePatch
	Remove most command line options and replace them by an option to specify
	location to motion.conf and a few options related to setting up motion.
	(Joerg Weber). This is also included in SetupModePatch.
	- Small improvement of the http control interface (link to setting itself
	on the html response when setting parameter) (Kenneth Lavrsen)
	
snap5	- Fixed a bug in noise tune which was most visible at very low light.
	(Joerg Weber and Kenneth Lavrsen)
	- Further improvement in the setup mode. Messages are now prefixed by
	the thread number in [brackets]. Moved 2 funtions from motion.c to
	picture.c. The setup mode patch is now considered finished. (Joerg Weber)
	
snap6	Netcam fixes and debug code by Christopher Price
	http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamStabilityPatch
	snap5_post1_video.c and snap5-post1 patches
	- Fixed netcam startup race condition.
	- Refactored image handling back to single unified function 
	- Refactored reconnection algorithm 
	- Jpeg only based connections should now use less cpu time 
	- Temporarily removed support for devices that do not support content-length
	(in progress) 
	- Synced syslog/printf style to new motion standard
	- Added developer debug trace defines/code
	- Defines now used for many constants
	
snap7	- Improved console output in setup mode. Now also outputs threshold.
	(Joerg Weber)
	- Added some additional text to the motion http messages to the terminal
	so that you know where the messages come from. (Kenneth Lavrsen)
	Netcam Stability Patch version snap6-post1 (Christopher Price)
	- Added support for netcams without content-length header (streaming only) 
	- Remove memmem from netcam_wget.[c|h] (no longer used) 
	- Several miscellaneous code cosmetic changes 
	- TODO: remove tests for memmem from configure
	
snap8	- Added support for non-streaming (image based) netcams without content-length
	header. (3.2.1-snap7-post1 version of the Netcam Stabilty Patch by Christopher
	Price).
	- Improvement in the noise-tune algoritm (Joerg Weber)
	- Re-arranged many of the const char declarations so that they are always
	before any statements within a block { }. This is to avoid compiler errors
	with older but still used gcc versions such as 2.95. (Kenneth Lavrsen)
	- Changed the use of %zd to %llu in printf statements of size_t types.
	This is done to avoid compiler errors with older but still used gcc versions
	such as 2.95. (Kenneth Lavrsen)
	
snap9	- Fixed even more gcc 2.95 compiler errors (declarations not at beginning
	of block) (Kenneth Lavrsen).
	- Removed a gcc 2.95 compiler warning (netcam.c:1036: warning: variable `pic'
	might be clobbered by `longjmp' or `vfork') (Kenneth Lavrsen)
	- The values for cnt->locate and cnt->new_img are now #defines in motion.h
	to enhance code readability (Kenneth Lavrsen).
	- The setting of sql_mask is now only done once per second to save CPU power
	(Kenneth Lavrsen)
	- Adding checking for conflict between control port and webcam port. Webcam
	port for a thread is disabled if it is set to the same value as the control
	port (Kenneth Lavrsen).
	- Fixed some file descriptor leaks in webcam.c and netcam.c (Christophe
	Grenier)
	- Added "motion-http:" prefix to error messages from the http control thread.
	(Kenneth Lavrsen)
	- Added additional error information when connection to MySQL fails (Kenneth
	Lavrsen)
	- Initiate cnt->event_nr to 1 to avoid code related to end of events and long
	mpeg films to be run during startup of Motion. (Kenneth Lavrsen)
	- Added new function in event.c close_anything_open() which is called from
	send_sms, send_mail and exec_command in order to prevent file descriptor and
	open sockets to be inherited by the shell causing freezing and instability.
	Code contributed by Christophe Grenier, Christopher Price and Kenneth Lavrsen.
	- Added new context global cnt_list.control_socket_server set by the httpd
	thread so that the above mentioned close_anything_open() can close open
	control sockets (Kenneth Lavrsen).
	- Renamed the top level global context structure to cnt_list so it can be
	reached from child threads and by above mentioned close_anything_open()
	(Christophe Grenier).
	
snap10	- Fixed a problem when compiling with --without-v4l configuration.
	(Philip Marien)
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x03x27x112843
	- Threw away the file descripter leak fix from snap 9 because it caused
	more trouble than it fixed. Removed the close_anything_open() and the 
	cnt_list.control_socket_server field. Replaced it all with a simple
	piece of code that all server daemons call when started: setsid() followed
	by for (i=getdtablesize(); i>2; --i) close(i). Dirty and simple.
	(Kenneth Lavrsen)
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x03x21x070534
	- Fixed a bug where rate of fetching picture frames was disturned by
	the signal SIG_CHLD from exec_command programs terminating. The symptom
	was that the number of post_capture frames became inaccurate and motion
	in mpegs did not have constant time between frames. (Kenneth Lavrsen)
	- Fixed a bug where motion did not work with gap=1 (Kenneth Lavrsen).
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x30x073616
	- Added the feature gap=0 which now also works. It disables gap completely
	so that one single mpeg file is created. You can end the event from the
	remote control interface make movie feature using for example cron.
	This makes Motion close	the mpeg and make a new with event number increased
	by one. (Kenneth Lavrsen)
	- Improved the http remote control action features so that makemovie
	and snapshot for thread 0 (all) works on all threads instead of being
	ignored (Kenneth Lavrsen).
	- Moved some code in the beginning of the motion_loop to a position later
	to improve the accuracy of time calculations for the framerate (Kenneth
	Lavrsen)
	- Updated code so Motion again runs on FreeBSD (Angel Carpintero).
	- Removed chech for memmem from configure (Angel Carpintero).
	- Updated http control interface so that an additional check is done
	before saving config files (Angel Carpintero).
	- Fixed a problem with URLs http://192.168.1.3:8080/0 which did not
	work without a trailing space (Angel Carpintero).
	
snap11	- Implemented new Generic onxxxx features.
	Function --- Old Option --- New Option
	Start of event (first motion) --- execute --- on_event_start
	End of event (no motion for gap seconds) --- New! --- on_event_end
	Picture saved (jpg or ppm) --- onsave --- on_picture_save
	Movie starts (mpeg file opened) --- onmpeg --- on_movie_start
	Movie ends (mpeg file closed) --- onffmpegclose --- on_movie_end
	Motion detected  --- New! --- on_motion_detected
	http://www.lavrsen.dk/twiki/bin/view/Motion/OnXxxCommandsPatch and
	http://www.lavrsen.dk/twiki/bin/view/Motion/OnXxxxFeatureDiscussion
	(Joerg Weber)
	- More Netcam Stability Fixes (snap10-post1-6) (Christopher Price)
	   - Destroy mutexes in netcam_cleanup().
	   - Add reconnection for netcam_start() - this may block other cameras
	     from starting up!.
	   - Added additional defines for reconnect retries.
	   - Change reconnection timeouts to 60 seconds.
	   - Reworked close(sock) in netcam_connect, to insure future changes
	     won't forget to close the socket.
	   - Reworked reconnection for netcam_start() - disabled by default, see
	     source for INIT_RECONNECT_RETRIES.
	   - Break some long lines in code.
	   - Replaced sleep with nanosleep per suggestion by Kenneth Lavrsen.
	   - Added additional header validation check.
	   - Changed a couple fd references to use RBUF_FD. 
	   - Added error message if jpeglib error occurs.
	   - Removed additional header validation check.
	   - Limited times headers will be checked.
	   - Removed mutex lock around netcam_start() in video.c, hopefully race
	     conditions are fixed.
	   - Added additional headers in http request.
	   - Added back header validation (should fix netcam_read_header lockups).
	   - Detect when there is no data on socket in netcam_read_ functions
	     (should fix netcam_read_image_contentlength() and
	     netcam_read_image_no_contentlength() lockups).	    
	   - Rearranged timeout assignments for pthread_cond_timedwait() calls.
	   - Adjusted TIMEOUT_COND_WHICH to 4 seconds.
	http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamStabilityPatch
	- Improvements of motion.conf help comments including improvements in new
	onxxxx options. (Kenneth Lavrsen)

	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x03x30x011107
	- Fixed a bug of locate feature for movement images combined with the
	new output_normal best feature (Joerg Weber)
	- More Netcam Stability Fixes (snap11-post1-4) (Christopher Price)
	   - Reworked thread signal/wait conditions, should fix some race conditions.
	   - Use gettimeofday() to determine thread timeouts, results in better accuracy.
	   - Adjusted condition timeouts to smaller values due to usage of gettimeofday()
	     and rework of thread signal/wait conditions.
	   - Adjusted reconnection retries to 60 (every minute for an hour).
	   - Fix bug where motion will not quit if requested when reconnecting. 
	   - Cruft, feature creep and redudant code removed.
	   - Consolated reconnection capability to unified netcam_reconnect function.
	   - Rework netcam_start logic, minimize startup variables.
	   - Rework netcam_stream_read and netcam_single_read logic.
	   - Minor changes to netcam_next logic.
	   - Fix bug in streaming camera without content-length, recent mod broke.
	   - Fix bug in startup of single image reads without content-length.

	- Motion Guide refactored completely for 3.2.1 with better web navigation and
	auto generation of pages. Makefile updated so that the Motion TWiki topic
	MotionGuideOneLargeDocument is fetched when updating the guide and making
	releases. (Kenneth Lavrsen).
	
snap13	- Removed the debug_parameter option which had no use. Programmers can still
	use it because the code is only commented out. This change required a small
	update in the code that rewrites motion.conf so that a remote control command
	to write the config files still adds a text header for the thread section at
	the end of motion.conf (Kenneth Lavrsen).
	- Changed the default values for a few options: quiet on, webcam_maxrate 1,
	threshold_tune off, webcam_quality 50 (Kenneth Lavrsen).
	- Changed some cosmetics in the way motion.conf is written (space after #)
	(Kenneth Lavrsen).
	- Updated the motion-dist.conf to use default values unless there is a reason
	not to (Kenneth Lavrsen).
	- Fix the compile issue with official ffmpeg packages from debian (Angel
	Carpintero).
	- More Netcam Stability Fixes (snap12-post1) (Christopher Price)
	  - Newrote url parser, better syntax checking and error handling of urls.
	  - Userpass now allowed in url (http://user:pass@example.com/).
	  Netcam_userpass has precedence, it will override a userpass embedded in
	  the url.
	http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamStabilityPatch
	
snap14	- Added basic authentication to the http control interface introducing new
	config option control_authentication. (Angel Carpintero)
	- Fixed memory leak when restarting Motion from http control (Angel
	Carpintero).
	- Small improvement in configure script for Debian (Angel Carpintero)
	- Added the ability to clear an option to off (bool), 0 (int) or undefined
	(string) by submitting blank entry field in the http control interface.
	(Angel Carpintero).
	
snap15	- Added new feature which shows the fixed mask (in addition to the smart mask)
	in bright red on the Motion type images (Joerg Weber).
	http://www.lavrsen.dk/twiki/bin/view/Motion/FixedMaskFileOnMotionImagesPatch
	- Added new feature. When you specify a mask file in the config file and start
	Motion, and the mask file does not exist, Motion will create a new clear
	(white) mask file for you in the right size. Then it is easy to simply
	open the file in your favorite paint program and add the masking in black
	(Joerg Weber).
	http://www.lavrsen.dk/twiki/bin/view/Motion/FixedMaskFileOnMotionImagesPatch
	- Fixed a bug in the low_cpu feature where cpu load increased instead of
	decreasing because the framerate calculations were completely wrong. This was
	an old bug introduced in 3.0.1 (Kenneth Lavrsen).
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x04x24x205933
	- Improved the auto-brightness algoritm. When auto-brightness is enabled
	the brightness option becomes a target value for the brightness level.
	This should also close a bug report (Kenneth Lavrsen).
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x02x26x195358
	- http interface small fixes (motion-3.2.1_snap14-small-fixes 1.1) incl
	Add 'back' link to response_client errors (Angel Carpintero).
	http://www.lavrsen.dk/twiki/bin/view/Motion/MotionHttpControl
	- Started adding tuner_number as option. This is not fully implemented. First
	code is added and rest will be done in next snap. (Kenneth Lavrsen)
	
snap16	- Made the http control interface more RFC compliant (Angel Carpintero).
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x02x180550
	- Made the http control HTML responses nicer to look at as sources and
	therefore easier to debug errors (Kenneth Lavrsen).
	- Code style cleanup of webhttpd.c (Kenneth Lavrsen).
	- Fixed compatibility problem with Palantir. Fixed by making output more
	compatible with RFC (\r\n). Original fixes by Roberto Spadim and Angel
	Carpintero. However this fix made Firefox flicker even more than it normally
	does. Final fix which works in both Palantir client, Firefox and Cambozola
	was made by Kenneth Lavrsen. This closes the following bugs:
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x02x205307,
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x07x042849
	
snap17	- Fixed small bug when pre_capture buffer is resized during operation.
	(Joerg Weber).
	- In httpd control code: Fixed RAW syntax following API specs. (Angel
	Carpintero).
	http://www.lavrsen.dk/twiki/bin/view/Motion/MotionHttpControl
	- Added new conversion specifiers: %D (diffs), (noise) %K (motion center x),
	%L (motion center y), %i (locate width x) and %J (locate width y). These
	changes also required a refactoring of the alg_locate code. This change
	is part of the implementation of a generic tracking feature and it enables
	implementing external programs that can perform sinple prediction features.
	(Kenneth Lavrsen)
	http://www.lavrsen.dk/twiki/bin/view/Motion/ExtendReplaceConversionSpecifiersDiscussion
	http://www.lavrsen.dk/twiki/bin/view/Motion/GenericTrackingPatch
	- Fixed a bug in switchfilter which caused motion detection to not work
	when the feature was enabled (Kenneth Lavrsen).
	
Release	- Change the working directory to / in daemon mode. This way you don't have
	to kill motion to umount the partition from where you start it. (Christophe
	Grenier)
	http://www.lavrsen.dk/twiki/bin/view/Motion/ChdirNetCamWgetPatch
	- In netcam-wget header_get() didn't always in add a \0 string terminator.
	This was fixed by Christophe Grenier
	http://www.lavrsen.dk/twiki/bin/view/Motion/ChdirNetCamWgetPatch
	- Fix for Unknown content type with lumenera cameras (Kenneth Lavrsen)
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x06x174416
	- MotionHttpControl Patch motion-3.2.1_snap18-pre1 v,1.0 19 May 2005.
	Fixed some HTTP response codes and added header copyrights. (Angel Carpintero).
	http://www.lavrsen.dk/twiki/bin/view/Motion/MotionHttpControl
	- Implemented pthread fix by Christophe Grenier.
	http://www.lavrsen.dk/twiki/bin/view/Motion/PthreadFixPatch
	- Fixed problem compiling "ffmpeg reports only YUV420 is supported" when
	ffmpeg is a recent CVS version.	(Angel Carpintero)
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x22x213229
	- Man page updated. It is now semi-autogenerated in the Motion TWiki
	(Kenneth Lavrsen)
	http://www.lavrsen.dk/twiki/bin/view/Motion/MotionOptionsAlphabeticalManpage
	- Bug fix in netcam code: Sometimes motion try to free an invalid memory area

snap3	Bugfixes by Angel Carpintero
	- fix motion.spec, motion.spec.in
	- typo in configure.in , configure.in.freebsd
	- fix version number 


3.1.18	Formal Release - Summary of changes since 3.1.17.
	- Removed the Berkeley mpeg feature
	- New brightness, contrast, hue and saturation options.
	- Makefile with automatic check of dependencies and nicer user output.
	- Improvement of the rotate feature.
	- Added the new smart mask feature.
	- Added a new config option --without-optimizecpu which disables CPU
	specific compiler optimizations.
	- Configure help texts improved.
	- Added the pwc-10.0.5 version of pwc-ioctl.h. Also good for pwc 10.0.6.
	- Changing rotate, height and width via xmlrpc no longer affects the
	running	program. This change is done because many internal data structures
	and memory allocations cannot handle change of image dimensions/size.
	- Enabled use of leading spaces when changing text_left and text_right via
	xmlrpc by using quotation marks if the value starts with a leading space.
	- Speed optimizations for dilate and labelling code.
	- Significant speed improvement in the motion detection algoritm.
	- Motion images are now gray scale instead of green. Smartmask is shown
	in red.
	- Implemented FreeBSD auto-detection CPU/ARCH fix.
	- Removed the never finished prediction feature.
	- Implemented a major improvement of noise_tune.
	- Implemented ffmpeg-0.4.9 support.
	- Default for option 'ffmpeg_video_codec' is now mpeg4. mpeg1 is now only
	supported with the old ffmpeg-0.4.8.
	- Option 'output_normal' value set to 'first' makes Motion only save a
	jpeg from the first motion detected picture frame in an event.
	- Implemented Streaming Netcam Without Curl which enables connecting to
	network cameras both with single jpeg frame mode and streaming mjpeg
	mode. This enables much higher framerates with Netcams.
	- Corrected a small error in the usage help text
	- Improved the help and doc texts for config option night_compensate.
	- Improved the signal handling of ctrl-C and kill.
	- Implemented a POSIX compliant SIGCHLD signal handler to avoid floods of
	warnings and script zombies in some RedHat versions.
	- Reporting of the changes of noise detection level is now only displayed
	in the console (daemon off) when the always_changes option is enabled.	
	- Made the code in xmlrpc more correct and robust (handling of select()).
	- Fixed several bugs in the timelapse feature.
	

	Detailed changes for all 3.1.18 snapshot releases since 3.1.17
snap1	- Removed the Berkeley mpeg feature (code commented out)
	- Implemented a bugfixed version of
	http://www.lavrsen.dk/twiki/bin/view/Motion/BrightnessContrastPatch
	Released as snapshot for developers to merge other patches.
	The snap1 is not recommended for normal use.
snap2	- Improved the Makefile with automatic check of dependencies and
	nicer output for the user.
	http://www.lavrsen.dk/twiki/bin/view/Motion/MakefileWithAutoDependencies
	- Implenmented first phase of the rotate patch. Need to fix the storage
	method for image height and width
	http://www.lavrsen.dk/twiki/bin/view/Motion/RotatePatch
snap3	- Implemented phase 2 of the rotate patch
	- Added brightness patch options to motion-dist.conf
snap4	- Added the new smart mask feature. It is working but it is still under
	development. It currently outputs an extra smart mask timelapse movie
	when the normal timelapse is enabled. This will be removed in the final
	version. http://www.lavrsen.dk/twiki/bin/view/Motion/PatchSmartMask
	- Added a new config option --without-optimizecpu which disables the
	CPU specific compiler optimizations introduced with the rotate phase 2
	patch. The purpose of the new option is to enable a packager to build
	an RPM or deb package which is not tied to a specific CPU type.
	- Man page updated with the new brightness and smart mask options.
	- Configure help texts improved.
	- Added the pwc-10.0.5 version of pwc-ioctl.h.
	- Changing rotate, height and width via xmlrpc no longer affects the
	running	program. The user can change the options and write them to the
	config files and then restart motion. This change is done because many
	internal data structures and memory allocations cannot handle change
	of image dimentions/size.
	- Fixed the problem with leading spaces of text_left and text_right
	getting lost when saving with xmlrpc. For text_left and text_right
	Motion now puts the string in quotation marks if the value starts with
	a leading space.
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2004x10x24x135840
snap5	-Implemented the November 10 update for smartmask
	-Started resolving some of the signed vs unsigned char problems. There
	is still much to do here. snap5 is released to make the developers up2date.
snap6	-Merged in the DilateNineSpeedPatch
	http://www.lavrsen.dk/twiki/bin/view/Motion/DilateNineSpeedPatch 
	-Changed a few image char definitions to unsigned char. Still many to fix.
snap7	-Implemented the 15-Nov-2004 Smartmask patch which removed the smartmask
	debugging timelapse code and instead adds the smartmask info to the
	motion images and jpegs as red areas. Normal motion is shown in black
	and white (greytones). This concludes Joerg Webers smartmask feature.
	The patch is now in ReleasedScheduled state for 3.1.18.
	-Implemented Angel Carpintero's FreeBSD auto-detection CPU/ARCH fix.
	-Merged in Per Johnsson's DilateFiveSpeedPatch
	http://www.lavrsen.dk/twiki/bin/view/Motion/DilateFiveSpeedPatch
	-Removed the prediction feature from the code (commented out for now).
	- Included fix by Jan X.
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2004x11x13x202132
snap8	-Implemented an improvement of Smartmask so that the mask is cleared when
	the smart_mask_speed is set from a non-zero to zero (by Joerg Weber)
	-Implemented an improvement of noise_tune with smart mask (and probably
	also in general) (by Joerg Weber)
	-Improved the picture control function so that cameras are only probed
	when needed to avoid USB errors. (Kenneth Lavrsen)
	-Implemented new ffmpeg patch (Per Jnsson)
	http://www.lavrsen.dk/twiki/bin/view/Motion/FfmpegPatch049
	-Implemented new preview patch (Joerg Weber)
	http://www.lavrsen.dk/twiki/bin/view/Motion/PreviewShotsPatch
	-Removed commented code from obsolete Berkeley and Prediction features
	- Implemented labelling speed patch (Per Jnsson)
	http://www.lavrsen.dk/twiki/bin/view/Motion/LabelingSpeedPatch
snap9	-Implemented Streaming Netcam Without Curl which enables connecting to
	network cameras both with single jpeg frame mode and streaming mjpeg
	mode. This enables much higher framerates with Netcams. (by Christopher
	Price and Angel Carpintero).
	http://www.lavrsen.dk/twiki/bin/view/Motion/StreamingNetcamWithoutCurl
	-Implemented a significant speed improvement in the motion detection
	algoritm (by Per Jnsson).
	http://www.lavrsen.dk/twiki/bin/view/Motion/AlgDiffStandardMmxPatch
	-Fixed a small bug which caused in jumpy mpeg1 videos with ffmpeg 0.4.8.
snap10	-Corrected a small error in the usage help text
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x05x174139
	-Improved the help text for config option night_compensate in docs,
	conf.c, motion man pages and config file.
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x06x103939
	-Improved the Netcam patch (Angel Carpintero)
	http://www.lavrsen.dk/twiki/pub/Motion/StreamingNetcamWithoutCurl/
	(pre2 patch fixes problem with not detecting Content-length and segfaults
	in netcam)
	-Improved the signal handling of ctrl-C as suggested by Per Jonsson
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x06x181426
	-Implemented a POSIX compliant SIGCHLD signal handler as replacement for
	the traditional signal(SIGCHLD, SIG_IGN) which can cause floods of
	warnings in some RedHat versions. (Angel Carpintero and Kenneth Lavrsen)
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2004x10x26x134906
	-Changed the reporting of the changes of noise detection level so that
	it is only displayed in the console (daemon off) when the always_changes
	option is enabled. (Kenneth Lavrsen)
	-Changed the ffmpeg>0.4.8 = no mpeg1 gcc warning message so that it is
	clear to people that it is information and not an error message.
snap11	-Changed allocation of despeckle buffer to avoid a seg fault when using
	a netcam where the image is wider than defined in motion.conf width.
	-The noise tune value displayed in the upper left corner along with
	number of changed pixels is no longer displayed (was there for debugging).
	-Improved the Netcam patch (Angel Carpintero)
	http://www.lavrsen.dk/twiki/pub/Motion/StreamingNetcamWithoutCurl/
	(pre3 reconnection feature added)
	-Changed the SIGCHLD handler introduced in snap10 so that it is a shorter
	and faster function. Disabled this handler in the xmlrpc thread as this
	caused unnecessary loops of cpu cycles. Additionally made the code in
	xmlrpc more correct and robust (handling of select()) (Kenneth Lavrsen)
	-Fixed a bug in the timelapse feature. Both the rollover events of the
	timelapse video and timelapse shots could be missed if the CPU load was
	very high or the time was changes by ntp. Motion will now catch up a few
	seconds later if this happens. Also fixed the code for monthly rollover
	(Kenneth Lavrsen). 
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x23x133554
Release	- Fixed a bug in the timelapse feature. Both the rollover events of the
	timelapse video and timelapse shots could be missed if the CPU load was
	very high or the time was changes by ntp. Motion will now catch up a few
	seconds later if this happens. Also fixed the code for monthly rollover
	(Kenneth Lavrsen). 
	http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x23x133554
	- Small improvement in timelapse feature so that an image is added when
	the new mpeg is created and not waiting till the following timelapse
	(Kenneth Lavrsen).
	- Small improvement so that the timelapse rollover happens on the hour
	and not one timelapse past the hour (Kenneth Lavrsen). 

3.1.17	Bugfix release
snap1	- Removed annoying debug syslog message (input: #)
	- Implemented Peter Ilin's patch for handling vloopback pipes better
	when Motion receives SIGTERM or SIGHUB.
	- Implemented fix for compiling errors when building the FreeBSD version
	without bktr support.
	(http://www.lavrsen.dk/twiki/bin/view/Motion/FreeBSDFixCompile)
	- Commented out many unnecessary syslog debug only messages. The commented
	out code was first patched by Mike Lees patch related to syslog causing
	instability and hanging motion processes.
	(http://www.lavrsen.dk/twiki/bin/view/Motion/SyslogEventPatch).
	- Included Kalle Andersson's patch that ensures that Motion detaches from
	the stdin and stout devices so that a secure shell that was used to start
	Motion in daemon mode does not hang when you exit the shell.
	(http://www.lavrsen.dk/twiki/bin/view/Motion/DaemonDetachFromSTDIO)
snap2	- Implemented a new lightswitch feature so that is now triggers lightswitch
	detected based on the percentage of pixels set by the lightswitch option which
	is now an integer instead of a boolean. When lightswitch is detected motion
	skips 5 frames to allow camera to settle.
	- Fixed a bug in the autobrightness function.
	- Fixed a bug in netcam_start() - wrong imgs.size calculation
Release - Swapped width and height parameters in some functions. This has no influence
	on program execution. Just a cosmetic change.


3.1.16  Bugfix release
snap1	Fixed a configure error related to xmlrpc.
	Fixed a bug in the SQL code related to file type.
Release Fixed a seg fault problem in alg.c related to the locate feature.
	Made motion more robust to whitespace in its config files. It now
	accepts CR LF (DOS/Windows) and whitespace only lines no longer
	gives warning messages in syslog. Also cleaned up the conf.c
	function structure a little bit.
	

3.1.15  Summary of changes from 3.1.14 to 3.1.15.
	New features:
	- ffmpeg now supports mpeg4 and msmpeg4 in addition to mpeg1. Timelapse
	mpegs are always made with mpeg1 because this allows appending to
	existing mpeg when motion or timelapse is restarted. This also meant
	a change of the configure option --with-libavcodec to --with-ffmpeg
	which now needs to point to the parent directory that holds libraries.
	- configure has been significantly improved so that most people can
	simply run ./configure, make and make install with no parameters and
	all libraries should be detected automatically if they are installed
	like in most distributions.
	- rotation feature added which allows the camera to be mounted upside
	down or in portrait.
	- SQL (Postgres and MySQL) table format has been changed. The time
	related fields such as minute, hour, day, month and year has been
	replaced by a timestamp field called 'time_stamp'. Additionally a
	field called 'frame' has been added so that each file can be correctly
	sorted based on time_stamp and frame (picture frame number within one
	second). An additional field called 'text_left' stores the displayed
	text given by config option 'text_left'. And a field 'camera' has been
	added which stores the thread number.
	- The %v (event) prefix has been removed from the default filename
	for timelapse mpegs. It makes little sense to have the current event
	number as part of the timelapse filename as default.
	- A new feature called 'labeling' was added which is a great enhancement
	to the motion detection algoritm. It ensures that only the largest
	area of movement is included in the detection and it prevents noise
	and wind from makeing false detection. It should also make tracking
	work better.
	- Angel Carpintero ported motion and it's main features to freeBSD.
	The freeBSD is still very much beta and because of limited access to
	hardware we need more people to test the various features.
	- Motion is now also released as an RPM with both mysql, postgres,
	libcurl and ffmpeg support.
	
	Bugfixes:
	- Fixed the problem with default strings being written to thread
	config files when using the XMLRPC command motion.conf.write.
	- Implemented improvement of vid_putpipe so that Motion	does not spend
	time writing to a vloopback device which is not there.
	- Introduced reporting to syslog of writing to vloopback fails.
	- Memory clean-up improvements when Motion exits normally.
	- Fixed a small bug related to the filename given for onffmpegclose.
	- Provided more improvements of error handling.
	- Added additional error reporting to console.

3.1.15 Snapshot releases
snap1	Fixed the problem with default strings being written to thread
	config files when using the XMLRPC command motion.conf.write.
snap2	Implemented Ryan Ayers improvement of vid_putpipe so that Motion
	does not spend time writing to a vloopback device which is not there.
	Also introduced reporting to syslog of writing to vloopback fails.
	Ryan Ayers improved configure's ability to find custom installations
	of ffmpeg.
	Ryan Ayers provided misc. cosmetic changes in the code.
	Ryan Ayers rewrote the ffmpeg functions completely added support for
	new codecs/formats mpeg4 and msmpeg4. mpeg1 was improved also.
snap3	Implemented Ryan Ayers simplified ffmpeg patch where 10 ffmpeg
	functions are reduced to 5. The memory leak related to an unused
	filehandle has been resolved.
	Kenneth Lavrsen solved the timelapse related .mpeg.mpeg filename
	error.
	Kenneth Lavrsen removed the memory leak in ffmpeg.c related to the
	use of strdup without a free.
snap4	Implemented Ryan Ayers snap3 based ffmpeg patch that cleans up the
	code significantly, forces timelapse. The list of improvements:
	1. Forces timelapse to mpeg1 for the time being.
	2. Removes FILE* f declaration in ffmpeg.h since we no longer need it.
	3. Removes all picture_buf references.  This was carried over from
	output_example.c in ffmpeg-0.4.8.  However, we don't need it.  That is
	allocating space for picture->data, but motion already takes care of
	this for us with the newimg variable.
	4. Removed some old commented code ... tmpfilename, picture_buf stuff.
	Included Angel Carpintero's memory clean-up improvements when Motion
	exits normally.
snap5	Added Per Jnsson's rotate feature. When set to non-zero some extra
	CPU time is used for the rotation.
	Kenneth Lavrsen changed the ffmpeg code so that mpeg1 files are
	created using the libavcodec method and mpeg4 and msmpeg4 are created
	using the new libavframe method in ffmpeg.
	Kenneth Lavrsen added seconds and frame fields to the database feature.
	This means that users must add these two fields to the table "security"
	in existing databases when upgrading to 3.1.15.
	Kenneth Lavrsen removed the %v (event) prefix from the default filename
	for timelapse mpegs. It makes little sense to have the current event
	number as part of the timelapse filename as default.
snap6	Kenneth Lavrsen fixed a small bug related to the filename given for
	onffmpegclose.
	Joerg Webers added the new labeling motion detection feature.
	Angel Carpintero provided more improvements of error handling.
snap7	Kenneth Lavrsen changed the configure option --with-libavcodec to
	--with-ffmpeg and updated Guide and man pages and text in code and
	config file to match the new shared library way of using ffmpeg
	Angel Carpintero ported motion and it's main features to freeBSD.
	The freeBSD is still very much beta and because of limited access to
	hardware we need more people to test the various features.
	Angel Carpintaro created an updated specs file that enables Kenneth
	to build RPMs of Motion.
snap8	Kenneth Lavrsen added the new fields to the SQL security table
	camera (thread number), text (text_left) and time (timestamp).
	Angel Carpintero improved error handling for the webcam functions.
Release	Kenneth Lavrsen simplified the sql functions (1 instead of 3)
	and ensured that the text field is not assigned when text_left is
	an empty string. This allows for the field to be auto defaulted.
	Added additional error reporting to console.
	
	

3.1.14	2004 May 31
	Included Ian McConnell's fix for snapshots when using the
	"lastsnap" filename.
	Fixed the bug in advanced filename and text feature when event
	numbers go higher than 99.
	Included Angel Carpintero's improvement of configure reporting of
	missing shared libraries (Kenneth Lavrsen improved it a little
	further).
	Included Ian McConnell's timelapse close mpeg file when set to zero
	patch.
	Changed motion-control to make a proper output from motion.conf.list.
	Renamed ffmpeg_timelaps to ffmpeg_timelapse (we change now or never)
	Corrected man page (\n).
	Added setting access rights to 644 (755 for configure) when doing
	make dist.
	Small improvement on xmlrpc-api.html document.
	Included Angel Carpintero's fix for building motion without ffmpeg
	(missing #ifdef round newly added ffmpeg timelapse code)
	Fixed missing init of viddev.frequency causing VIDIOCGCHAN errors.
	Included Angel Carpintero's snap2 based patch for improving configure.
	XML-RPC changes of threshold and noise_level are now being used as
	long as threshold_tune and noise_level are not enabled.
	Enabled the round robin feature to also work by changing frequency on
	the same device and same input.
	Fixed the pre_capture feature so that it also stores the jpegs properly.
	Fixed the ffmpeg_timelapse feature so that the calculated time is
	correct and the current image is used instead of an old image from
	position 0 in the pre_capture ring buffer.
	Fixed ffmpeg routines so that also graytone images can be
	pre_captured and used with ffmpeg_timelapse.
	Fixed the position of the incrementing of shots in the motion_loop
	so that it is correct before any functions use it.
	Added quite many comments to the code to make it easier to maintain
	(more comments will be added).
	Removed some old debugging printf's that were displayed in non-quiet
	mode.
	Changed to snapshot feature from being alarm driven to being timer
	driven. This means that each thread can have its own interval
	value. The XML-RPC motion.action.snapshot still works. The SIGALRM
	method has been changed so that all thread that have the
	snapshot_interval non zero will take a snapshot when being signaled
	with SIGALRM. A	negative value for snapshot_interval will activate
	the SIGALRM trigger but not the timing interval.
	Implemented ffmpeg_timelapse_mode feature by James A. Russo.
	Implemented RH (sysV) and Debian type control scripts for /etc/init.d
	by Angel Carpintero.
	Implemented enhanced SQL features by James A. Russo. This adds logging
	of mpeg and prediction events to MySQL/PostgreSQL.
	James patch also replaced the mime file types by a more refined
	filetype scheme that allows more refined control for SQL and other
	future control.
	Kenneth Lavrsen changed the enhanced SQL config from single sql_mask
	option to 5 sql_log_ options for more user friendly control.
	Implemented Daniel Sterlings minimum_motion_frames feature.
	Plugged a memory leak in the pre_capture feature.
	Changed the behaviour of onsave back to original mode where also
	snapshots causes onsave command to be run.
	Fixed a bug in frequency setting of V4L device.
	Renamed snapshots_interval and snapshots_filename to snapshot_interval
	and snapshot_filename.
	Changed the webcam_port value to 0 in motion-dist.conf to avoid that
	people get segmentation faults when having 2 or more cameras and
	webcam_port not set in the thread config files.
	Implemented Daniel Sterlings improved handling of config strings. This
	plugs the memory leak when changing string type options via XML-RPC.
	It also makes the memory handling more elegant/optimal and finally
	it now allows strings to be as long as allowed by the environment
	variable PATH_MAX.
	Kenneth and Daniel added many comments to motion.c and conf.c.
	Daniel Sterling made the XMLRPC able to handle errors without crashing.
	Daniel Sterling and Kenneth Lavrsen added a feature that checks for
	two threads having the same webcam_port. If this is the case the last
	thread gets its webcam disabled and a warning message is written
	to console and syslog.
	Implemented Daniel Sterling's fix for a small calculation error in
	alg_diff_fast().
	Small improvements in messages sent to console and syslog during
	startup of Motion.

	make install overwrites your perfectly OK working motion.conf
	file when you re-install.
	Updated the motion.spec.in. Not tested yet.

	to find and use a dynamic library of ffmpegs libavcodec.so .
	Included Steffen Haas improved on screen display patch
	(plus some extra characters including a real space).
	Changed the parsing of the motion.conf and thread.conf files so
	that spaces are now allowed. This also enables using a space in
	the user text. For XML-RPC you put text in "" if you need spaces.
	Changed the XML-RPC function motion.conf.write so that undefined
	config options gets written into the main motion.conf file with
	the help line and the option prefixed by a '#'. Example
	# netcam_url value.
	Added Mike Lees onffmpegclose feature which enabled a command to
	be executed each time a file generated by ffmpeg is closed.
	Added Daniel Sterlings night compensate fix.
	Added Angel Carpintero's improved configure process which
	automatically detects presence of xmlrpc-c and ffmpeg and makes
	the Makefile accordingly.
	Included Ian McConnell's flexible on screen display feature and
	flexible strftime based path names.
	Changed conf.c so that xml-rpc command motion.conf.write creates
	a much more user friendly motion.conf file.
	Modified Ian's on screen display putting back the config parameter
	(draw)text_changes. If enabled the number of changed pixes are shown
	in the upper right corner of the image.
	Removed the snap_override feature and reduced the oldlayout to an
	Berkeley mpeg_encode feature only renaming it to
	berkeley_single_directory. Instead the flexible filename
	feature now has oldlayout as default and the "new" directory layout
	specified in the motion.conf file.
	Motion.conf sequency re-arranged so the important things comes first.
	Changed names of many options to be more user friendly.
	Renamed the options for displayed text to text_right, text_left and
	text_changes.
	Change the parsing of config files so that the argument can be in
	quotation marks (" or ') allowing leading spaces for the text_left
	and text_right options. This means that you can place the text
	anywhere on the picture by using spaces and new lines \n.

	post_capture.
	Redone pre_capture completly.

3.1.12
rc1	added pre-record. with configparameter n_prerecord one can set
	the number of frames that should be recorded *before* the
	motion starts. for this feature to work, you need to set
	post capture to at the value given for n_prerecord! also:
	n_prerecord must be at least 1

3.1.11	found 2 memory-leaks (two 'FILE *' were not closed) in the

3.1.10	added Kenneth's fixes for ffmpeg instability and the problem
	with the "ioctl(VIDIOCGCHAN): Invalid argument" error
	small optimalisation of rgb24toyuv420p (about 6% faster) so
	for certain video-devices things might be a little faster
	optimized alg_diff_fast: about 50% faster
	made it compile again with 2.6.0-test9
	noise tuning is now only done when there's no motion!
	noise is resetted to the median of the tuned value and the
	configured value as soon as no motion is detected
	fixed includes for mysql/psql (thanks Felix Finch!)

3.1.9	motion now logs to syslog instead of stderr, that way it is
	still possible to see what is going wrong when motion runs
	as a daemon process.
	motion will now exit nicely when memory allocation fails
	instead of segfaulting
	low_cpu now takes the number of frames per second to process
	when no motion is detected instead of on/off
	"quick motion detection" is now only performed when motion
	is in "idle" mode.
	added Kenneth's patch: motion with ffmpeg-0.4.8 now compiles
	again!
	small optimalisation: if a file is created, the path is now
	only recreated when it did not already exist.
