Release Note - Motion 3.1.18

3.1.18 - 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 dimentions/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 snap shot releases since 3.1.17

• Removed the Berkeley mpeg feature (code commented out)
• Implemented a bugfixed version of http://www.lavrsen.dk/twiki/bin/view/Motion/BrightnessContrastPatch

• 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

• Implemented phase 2 of the rotate patch
• Added brightness patch options to motion-dist.conf

• 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

• 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.

• 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.

• 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 ReleasedSnapshot 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

• 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 Jönsson) 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 Jönsson) http://www.lavrsen.dk/twiki/bin/view/Motion/LabelingSpeedPatch

• 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 Jönsson). http://www.lavrsen.dk/twiki/bin/view/Motion/AlgDiffStandardMmxPatch
• Fixed a small bug which caused in jumpy mpeg1 videos with ffmpeg 0.4.8.

• 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.

• 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

• 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).
