Compiling and running from motion revision 564 using ffmpeg 2.6.2 built
from source (from https://www.ffmpeg.org/download.html#releases).
*Here is my analysis so far:*
the only changes are the recommended addition of videodev2.h to track.c and
the additions to the Makefile LIBS of *-lswresample -lva*
*The segfault happens when ever movement is detected.*
gdb takes me to an issue where ffmpeg 2.6.2 ->* libavformat/utils.c* ->
subroutine *avformat_new_stream* -> line 3718 is the issue:
*st->inject_global_side_data = s->internal->inject_global_side_data;*
from gdb I see "s->internal" is null and thus is causing the segfault.
*"s->internal" *is a* AVFormatInternal*
*Here is the gdb stuff*
