video motion detection of linux base

     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)

   * 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)

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)
     http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamStabilityPatch
      * 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.
   * Improvements of motion.conf help comments including improvements in new
     onxxxx options. (Kenneth Lavrsen)
