Motion Snapshot Release 3.1.18_snap8

Release Notes

3.1.18 snap8 - 10 Dec 2004

Development Release - not recommended for normal use

Released as snapshot for developers to merge other patches. And for general testing among the ones that wants to help finding bugs.

Changes since 3.1.17

snap1

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

snap2

• 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. PerJonsson is working on a phase 2 of the patch to ensure that changing height and width via xmlrpc is not changing the current width/height as this screws up a lot of malloc'ed memory.

snap3

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

snap4

• 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

snap5

• Merged in the November 10th update of smartmask.
• Started working on fixing the signed vs unsigned issue related to handling of images. The snap5 is created to get the developers in sync.

snap6

• 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.

snap7

• 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). This was done because feature was never completed, noone showed real interest to finish it and there was an almost silent acceptance when it was proposed on the Motion Mailing List.
• Included fix by Jan X. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2004x11x13x202132

snap8

• 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

Next Steps

• NetcamDecompressInMemory patch
• Address some signed chars that maybe should be unsigned in alg.c

Pending patches are

• StreamingNetcamWithoutCurl still too unstable to enter the mainline code without more development on it. The feature itself is high priority.
• LosslessEncoding is a nice to have feature with lower priority. If it works it is in. If not it is out until someone makes it work.

Known Problems

• Motion Guide not yet updated - will wait until more patches are applied.

• The pwc-ioctl.h is for pwc version 9.0.1 and 10.0.5. 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.

Bug Reports

Error on Configure

On Fedora Core 3 i got : checking size of short int... configure: error: cannot compute sizeof (short int), 77

Solution : install libidn-devel-0.5.6-1.i386.rpm

PerJonsson found and corrected a small bug in the ffmpeg code.

In ffmpeg.c line 272 remove this line

c->max_b_frames = 1;

It makes the mpeg1 films more smooth.
