Description Marcin Jurkowski 2015-06-15 19:27:44 UTC

Motion compiled with ffmpeg 2.2 or newer segfaults as it tries to write a new avi file. The segfault actually occurs in init_muxer() libavformat function and it's caused by improperly initialized AVFormatContext structure, using av_mallocz() instead of avformat_alloc_context().

The reason for this bug is that gentoo-specific patches (ffmpeg-2.patch, ffmpeg-3.patch, ffmpeg-4.patch), meant to support wide range of ffmpeg versions, introduced #ifdefs in the code and suitable check in configure.in, however the build still uses the old, upstream configure script.

In short, configure script must be regenerated after patching upstream sources.



Reproducible: Always

Steps to Reproduce:
1. Compile motion with ffmpeg 2.2 or 2.6
2. Start motion service
3. Wait till it detects and start recording a motion sequence

Actual Results:  
The motion process immediately crashes, leaving empty (zero-byte) avi file.
