Motion Snapshot Release 3.2.2 snap8

Release Notes

• Pthread deadlock in motion 3.2.1 fixed (Angel Carpintero) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x26x125712.
• http lockup bugfixes and http://www.lavrsen.dk/twiki/bin/view/Motion/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 conversion 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).

• 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)

• 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).

• Fixed the ffmpeg code so that Motion also compiles against libavcodec build 4754 or later. (Per Jönsson)
• 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

• 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 Hollik). 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).

• 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).

• 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

• 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

Next Steps

• A lot of testing of the brand new netcam code.
• Fix open bugs.
• tuner_number will be introduced later when Motion eventually supports V4L2. Will not be in 3.2.2.
• Add the two new conversion specifiers to Motion Guide and man page.
• Range checking of options - includes a complete redesign of how options are loaded and changed via remote control. This redesign is mainly making the code more robust and should be transparent to the user.

Known Problems

• See the http://www.lavrsen.dk/twiki/bin/view/Motion/BugReports for open bugs.
• The pwc-ioctl.h is for pwc version 9.0.1 and 10.0.6. If you still use the pwc 8 series then you need to use the headerfile pwc-ioctl.h-pwc8.0 (copy the pwc-ioctl.h-pwc8.0 over pwc-ioctl.h). This is relevant for USB cameras using Philips chips.
