video motion detection of linux base

3.2.7 Formal Release - Summary of Changes

Features
   * Removed the minimum_gap feature which was utterly useless (Kenneth Lavrsen)
   * Added new feature: minimum_frame_time which enables capturing at a lower rate
     than 2 frames per second (Kenneth Lavrsen and Angel Carpintero)
   * Made the creation of reference frame and the decay mechanism depending
     on how much motion was detected relative to threshold setting (Joerg Weber)

Bugfixes
   * Fixed problem related to fetching images from Network camera and error
     handling when it fails. Motion would end in infinite loops (Bill Brack).
     http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2006x03x10x000151
   * Improved reporting of thread numbers during startup in setup mode.
     (Peter Smith and Kenneth Lavrsen)
     http://www.lavrsen.dk/twiki/bin/view/Motion/SlightlyImprovedThreadCreationLogging
   * Ffmpeg code mutex locking fix (Peter Smith)
     http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2006x04x07x164654
   * Ffmpeg avicodec logging improved (Peter Smith and Kenneth Lavrsen)
     http://www.lavrsen.dk/twiki/bin/view/Motion/FfmpegAvicodecLogging
   * Improved upon a few ambiguous log messages which may be emitted by the Event
     handling code with regards to Ffmpeg (Peter Smith)
     http://www.lavrsen.dk/twiki/bin/view/Motion/LoggingEventFix
   * Implemented a fix for the rare problem where some experienced that the
     move file names would only consist of the extension .mpg or .avi with no
     name in front. The root cause was the use of sprintf for appending to
     strings. (Mike Kenney and Kenneth Lavrsen)
     http://www.lavrsen.dk/twiki/bin/view/Motion/SupportQuestion2005x09x05x133031
     http://www.lavrsen.dk/twiki/bin/view/Motion/SupportQuestion2006x06x19x174238
   * Altered the risky use of sprintf to snprintf in all places related to
     use with config strings that can become very long (Kenneth Lavrsen)
   * Removed annoying debug messages (v4l_set_input really needed ?) in the FreeBSD
     version (Angel Carpintero)
   * Fixed the check for ffmpeg version. In rev 5503 of ffmpeg the FFMPEG_VERSION_INT
     was removed from libavcodec/avcodec.h. Instead we now use the equivalent
     LIBAVFORMAT_BUILD >= 4616 which is the 0.4.9pre1 version of ffmpeg.
     (Kenneth Lavrsen)
   * Fixed segfault when netcam_url has no service ( http , ftp ) (Angel Carpintero)
   * Fixed interlace issue with METEOR_GEO_EVEN_ONLY in FreeBSD (Angel Carpintero)
   * Fixed possible syntax error in configure related to MySQL (Angel Carpintero)
   * Avoid open file descriptor when connecting to network cameras fails (Peter Holik) 
     http://www.lavrsen.dk/twiki/bin/view/Motion/AvoidOpenfiledescriptors
   * Fixed http pause feature so that pausing thread 0 now pauses all threads.
     (GunnarSkjold)
     http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2006x07x10x111239
   * Put a new global mutex arround avcodec_close to avoid problems with not thread
     safe functions in ffmpeg (Angel Carpintero)
     http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2006x04x07x164654
   * On FreeBSD configure defines a redundant freebsd for motion. Fixed by replacing
     -D__freebsd_ by BSD macro  included in sys/param.h for BSD platforms.
     (JukkaUkkonen and Angel Carpintero)
     http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2006x07x08x070417
   * For BSD platforms changed to using native pthreads as default and adding
     linuxthreads as a optional parameter from configure. (Angel Carpintero)
     http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2006x07x08x071646
   * Smartmask overlay feature did not set intensity correctly. (Kenneth Lavrsen)


3.2.6 Formal Bugfix Release.
   * Fixed bug where variables time_last_frame and time_current_frame had been
     extended to also be used for snapshot feature but declaration was hidden
     between #ifdef HAVE_FFMPEG. (Kenneth Lavrsen)
     http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2006x03x09x012244
   * Fixed a bug that only allowed remote control of max 9 cameras. Now
     Motion can present up to 99 cameras in its http remote control interface
     (Angel Carpintero based on idea by Chuck Sheehan)
     http://www.lavrsen.dk/twiki/bin/view/Motion/WebHttpManyThreads
   * text_changes now shows a '-' when motion detection is paused instead of
     just showing 0 (Kenneth Lavrsen)
     http://www.lavrsen.dk/twiki/bin/view/Motion/FeatureRequest2006x03x16x095713

3.2.5.1  Doc and man page correction
   * ffmpeg_filename has changed name to movie_filename to prepare for
     alternative movie encoding to the current ffmpeg based implementation
     and ffmpeg_filename will then be a bad name (Kenneth Lavrsen)
   * Man page corrected.

     http://www.lavrsen.dk/twiki/bin/view/Motion/FixStringsAndDisableLabeling
   * Fix many typos in comments ( i ran aspell against the code ). Also there's a 
     fix to free cnt->eventtime_tm when motion exits. (Angel Carpintero)
     http://www.lavrsen.dk/twiki/bin/view/Motion/FixTypoInComments
   * Fix the problem that happens in FreeBSD and Debian Sarge because 
     version of ffmpeg is LIBAVFORMAT_BUILD < 4629. ( Pete Shipley and Angel Carpintero)
     http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2006x01x12x120335
   * Updated motion.spec. Changing D_FORTIFY_SOURCE=2 by D_FORTIFY_SOURCE=1 to fix
     problem related to building with ffmpeg. (Angel Carpintero)

     http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2006x02x07x162149
   * Added some constants in video.c function v4l_picture_controls() which can help
     people hack an optimal set of values for controlling auto brighness for their
     particular camera. For now I am do not want to add all of these to the already
     too large number of motion config options. Maybe based on feedback we can
     permanently change the constants and add an additional auto brightness option.
     Or maybe a combined option that sets more constant based on an algoritm.
     (Kenneth Lavrsen)
     http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2006x02x07x212816
   * Fixed a syntax error in picture.c get_pgm() which caused the program to seg
     fault when a mask file size did not match the picture size. Now the program
     correctly gives an error message and continues without the mask. (Kenneth
     Lavrsen).
     http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x10x08x150720
   * Added Tilt support to stepper track. ( Angel Carpintero ).
   * CPU VIA Ezra C3 autodetection support added. (James Van Vleet)
     http://www.lavrsen.dk/twiki/bin/view/Motion/VIAEzraC3Patch
   * Fixed mysql configure auto-detection for x64 systems. ( Angel Carpintero)
     http://www.lavrsen.dk/twiki/bin/view/Motion/SupportQuestion2006x03x02x152208
   * Added the ffmpeg_deinterlace feature (Andrew Hamilton)
     http://www.lavrsen.dk/twiki/bin/view/Motion/MotionffmpegDeinterlace 	

3.2.4   Formal Release. Summary of changes

Features
   * New text option text_event and new conversion specifier %C. Option
     text_event defines the value %C which then can be used in filenames and
     text_right/text_left. The text_event/%C uses the time stamp for the first
     image detected in a new event. Default value is %Y%m%d%H%M%S. %C is an empty
     string when no event is in progress (gap period expired). Pre_captured
     and minimum_motion_frames images are time stamped before the event happens
     so %C in text_left/right does not have any effect on those images.
   * Added new option track_auto which is a boolean option (on or off)
     with default value off. This enables people to start Motion with auto
     tracking enabled. Changing the config value for track_auto and
     enabling the auto tracking via the httpd track/auto has the exact same
     effect.
   * Added 3 new tracking options: track_step_angle_x, track_step_angle_y,
     and track_move_wait. The options track_step_angle control the movement
     during auto tracking and are currently only active for the pwc type
     tracking. The idea is that they can later also be used for the generic
     tracking as it evolves. The track_move_wait controls the number of frames
     after the camera has moved (auto or manual) during which motion detection
     is disabled. This option should be set so low that the motion detection
     is re-enabled the minute the camera is standing still again.
   * Added new sql_query option. This in combination with convertion
     specifiers incl the two new %f and %n enables the user to use any database
     structure they please. Adding fields is now a simple matter of modifying
     the sql query.
   * Added the %t conversion specifier which is the thread (camera) number.
   * Added two new conversion specifiers: %f which is filename (full path)
     and %n which is filetype (sqltype) valid in on_picture_save, on_movie_start,
     on_movie_end and sql_query. This also means that filename is no longer
     appended at the end of the 3 on_xxxx commands.
   * http control had a number of small improvements.
   * Added the debian sub directory so that people can build the deb package.
   * Enhanced netcam compatibility with Lumenera and Pixord Cameras.
   * Netcam feature now supports both http and ftp.
   * Added an infinite retry scheme for netcams that are not available
     when Motion is started. Instead of just dying, Motion now retries every
     10 seconds until the netcam is available. Until the netcam is available
     Motion enters a mode showing a grey image with a text information which
     is fed to webcam, timelapse, snapshots, vloopback etc. If the actual
     height and width of the netcam does not match the dimentions in the
     config file Motion will perform a quick restart.
   * Added a better error handling of a netcam that changes dimensions
     while Motion is running. Instead of just writing error messages Motion
     restarts quickly to recover from this change.
   * FreeBSD Code improvements including set/get hue, saturation, contrast
     and brightness, support large resolutions.
   * RPM specs file changed as suggested for use in the Livna repository.
   * Changed the sequence of events connected with creating files. Data is
     now written to the databases (if used) before an external commens is
     on (on_xxxx options) allowing the external program to use the new data
     in the database.
   * Motion is now also works on MaxOSX with similar feature set as FreeBSD.

Bugfixes
   * netcam code now waits for the next frame to arrive for a limited period
     in order to avoid too many duplicate images.
   * Motion loop resets its frame timer when the image received is from a netcam.
     This lowers the actual framerate of Motion to the rate the netcam can actually
     keep up with.
   * Removed all warnings when running ./configure --with-developer-flags.
   * Fixed error message with unknown config option.
   * Fixed small mistake in allocating memory for cnt->imgs.common_buffer.
   * Implemented a speed-up patch of the draw text feature.
   * Introduced check for device image size being a multiple of 16.
   * Switchfilter feature repaired.
   * Fixed small bug where motion was detected when using a tracking camera and
     the camera moved to center position when gap period expires.
   * Implemented fix to configure so that LDFLAGS from the environment are used
     when making the Makefile.
   * Changed configure so that --with-jpeg-mmx is default off as a reaction to
     known problems seen when using the jpeg-mmx library.
   * The lightswitch and switchfilter features have changed to ensure that both
     algoritms work on raw unfiltered motion pixels which they both were designed
     for.
   * Fixed bug related to init of mutex in netcam code.
   * Fixed small bug where the displayed time in the grey error image
     shown during start with unavailable netcam could show a garbage value
     under rare circumstances.
   * Restored the function sigchild_handler so it contains the same code
     as before motion-3.2.1_snap9. They is done in an attempt to fix an old
     problem with zombie child processes that has shown up again.
   * Added a work-around so people in FreeBSD that uses a capture card
     where input 1 is not tuner can use motion if frequency is set -1 in
     motion.conf or thread#.conf
