video motion detection of linux base

3.2.4     Detailed changes for 3.2.4
snap1
   * Removed all warnings originating from the motion sources when running
     ./configure --with-developer-flags.
     The modifications were done by the following people: Peter Holik, Bill Brack,
     Angel Carpintero and Kenneth Lavrsen.
     We now encourage developers to ensure that new code is checked with
     --with-developer-flags and code made so that no new warnings shows originating
     from the motion sources.
     http://www.lavrsen.dk/twiki/bin/view/Motion/ReduceWarningsPatch
   * Fixed error message with unknown config option (Bill Brack)
   * Fixed small mistake in allocating memory for cnt->imgs.common_buffer
     (Angel Carpintero).
   * Implemented a speed-up patch of the draw text feature (Peter Holik).
     http://www.lavrsen.dk/twiki/bin/view/Motion/DrawTextspeedup
   * http control updated: (null) messages replaced by "disabled", last parameter
     in conf/list are displayed correctly and only in Main thread. When motion runs
     with only one thread, it displays "No threads". (Angel Carpintero)
   * Enhanced compatibility with Lumenera (Bill Brack)
   * http control: selectbox instead of a textfield for changing boolean configs
     (Peter Holik and Angel Carpintero).
     http://www.lavrsen.dk/twiki/bin/view/Motion/WebhttpEnhancements.
   * Introduced check for device image size being a multiple of 16 (Peter Holik).
     http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamModulo16Patch
   * Added the debian sub directory so that people can build the deb package
     (Angel Carpintero).
   * Sync configure.in.freebsd (adding support for jpeg-mmx, developer-flags and
     some cosmetic changes ) (Angel Carpintero)
   * Implemented --with-developer-flags fixes in FreeBSD code (Angel Carpintero).
   * Implemented Threadnr in TLS (thread-local storage)patch. It puts the thread
     number into TLS and modifies motion_log() so that we do not have to drag the
     cnt struct around just to be able to print the thread number in the log and
     on the console. (Per J鰊sson with additional removal of unuseded cnt by
     Kenneth Lavrsen).
     http://www.lavrsen.dk/twiki/bin/view/Motion/ThreadNrTlsPatch
   * Moved the motion_loop initialization into a new function motion_init
     (Bill Brack).
   * Removed old unused code related to read mode (not mmap) from V4L devices
     (Kenneth Lavrsen).
   * In v4l_start change map from unsinged char * to void * to be ANSI C compliant
     with mmap (Angel Carpintero)
   * http control: Changed disabled to (not defined) when displaying option list
     (Angel Carpintero)
   * netcam code now waits for the next frame to arrive for a limited period
     in order to avoid too many duplicate images (Bill Brack).
   * 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. (Kenneth Lavrsen)
   * Last --with-developer-flags warnings eliminated simply by swapping the
     order of the #include statements in the sources (Bill Brack and Kenneth Lavrsen).
   * FreeBSD Code improvements by Angel Carpintero
      * Implemented set/get hue , saturation , contrast and brightness.
      * Better support to capture with big resolution ( 640x480 , 768x576 ).
      * Update Readme adding information about "how to configure a capture
        card and settings" , update packages dependencies .
      * Remove support for libjpeg-mmx , motion sefgault ( future fix ).
      * Cosmetics changes in configure.in.freebsd ( replace --without-v4l by
        without-bktr ).
      * Cleanup code and fix warnings.

snap2
   * Simplified rotation code based on the fact that images must have dimentions
     that are a multiple of 16 (Per J鰊sson)
     http://www.lavrsen.dk/twiki/bin/view/Motion/RotateSimplificationPatch
   * Switchfilter feature repaired. It was called inside motion_detected()
     after overlays on cnt->img.out were added which meant that the feature also
     detected all the overlays, smartmasks, fixed mask and text. It is now moved
     to the motion_loop right after the lightswitch feature and before any
     overlays are added (Kenneth Lavrsen).
   * Fixed small bug where motion was detected when using a tracking camera and
     the camera moved to center position when gap period expires. The fix includes
     gathering the updating of reference frame in one place only in the motion_loop
     (Kenneth Lavrsen).
   * Implemented the 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 (Kenneth
     Lavrsen).
     http://www.lavrsen.dk/twiki/bin/view/Motion/EventConvertionSpecifierDiscussion
   * Renamed some variables related to time to be better descriptive of function
     and type (Kenneth Lavrsen).
   * Added new option 'sql_user_text'. This can be defined with the same
     conversion specifiers as text_xxx, on_xxxx and filenames. The SQL field
     text_left has been removed and replaced by a field user_text which is
     used for storing the interpreted value of sql_user_text (Kenneth Lavrsen)
   * Added new SQL field event_time_stamp of the type TIMESTAMP
     (Kenneth Lavrsen).

snap3
   * Enhancement to Netcam Code for Connection to Pixord Cameras (Bill Brack).
     http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamFixPixordBug
   * Implemented fix to configure so that LDFLAGS from the environment are used
     when making the Makefile (Angel Carpintero).
     http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x09x15x185558
   * Changed configure so that --with-jpeg-mmx is default off as a reaction to
     known problems seen when using the jpeg-mmx library (Angel Carpintero).
   * RPM specs file changed as suggested for use in the Livna repository.
     (Kenneth Lavrsen)
   * The lightswitch and switchfilter features have been moved up before the
     despeckle features are run. This should ensure that both algoritms work on
     raw unfiltered motion pixels which they both were designed for. (Kenneth
     Lavrsen)
     http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x10x05x212444

snap4
   * Integrated NetcamWithFtp patch. To use ftp simply use a URL starting with
     ftp:// (Bill Brack). Code was additionally cleaned up by Kenneth Lavrsen.
     http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamWithFTP
   * Changed error handling in vid_start so that failing to open the video
     device no longer causes an exit but a return with error code -1. (Kenneth
     Lavrsen)
   * Added the %t conversion specifier to show the thread number. (Angel
     Carpintero).
     http://www.lavrsen.dk/twiki/bin/view/Motion/ThreadConversionSpecifierPatch
   * Added help texts in conf.c and motion-dist.conf describing the %t
     specifier. Added a good example of use in motion-dist.conf. (Kenneth
     Lavrsen).
   * Fixed bug related to init of mutex in netcam code (Angel Carpintero).
   * Improved fix for netcam mutex init (Bill Brack).
     http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamFixPthreadInit
   * Netcam_ftp code fixes (Angel Carpintero and Asbj鴕n Pettersen)
     http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamWithFtpEnhancements
   * Enhanced ffmpeg detection (Angel Carpintero).
     http://www.lavrsen.dk/twiki/bin/view/Motion/BetterFFmpegDetection
   * 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. (Kenneth Lavrsen)
   * Removed the sql_user_text option that was added in snap 2 (Kenneth
     Lavrsen)
   * 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. Added fields is now a simple matter of modifying
     the sql query. The default is the same as the default in snap1.
     (Kenneth Lavrsen).
   * 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 (Kenneth Lavrsen).
   * 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 the normal flow with the same grey image with a text
     information being fed to webcam, timelapse, snapshots, vloopback etc.
     Motion uses the width and height from the config file for this. It is
     a good idea to setup width and height so it is the same as the netcam.
     If the dimentions are the same Motion will switch over to the netcam
     seemlessly. If the dimensions are different Motion will perform a quick
     restart so all the many internal buffers can be initialized properly
     (Kenneth Lavrsen).
   * 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. Note the now more well
     defined error coding for vid_next for both netcams and V4L cams.
     (Kenneth Lavrsen)

snap5
   * 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. (Kenneth Lavrsen).
   * 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.
     http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x11x13x115016
     (Kenneth Lavrsen).
   * Move the declaration of sig_handler_action and sigchild_action from
     the setup_signals function where they are local and will be destroyed
     and out in main just before setup_signals is called. Changed the
     function setup_signals so the two structs are passed as pointers.
     (Kenneth Lavrsen)

Release
   * Added new option track_auto which is a boolean option (on or off)
     with default value off. This enable 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. (Kenneth Lavrsen)
   * 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. Feature
     originally made by Moshe Van Der Sterre. Kenneth Lavrsen extended it to
     be more generic.
     http://www.lavrsen.dk/twiki/bin/view/Motion/PwcConfiguration
   * New Feature: Motion is now also supported on MaxOSX with similar
     feature set as for Free BSD. See README.MacOSX for details how to install
     it. (Angel Carpintero)
     http://www.lavrsen.dk/twiki/bin/view/Motion/MacOSXPatch
   * 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 (Angel Carpintero).


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).
