Summary: ffmpeg (mingw64 x86_64 GCC 4.7.0, yasm 1.2.0) crashes when trying
to decode a dirac stream.
This however doesn't happen if i compile ffmpeg with the --disable-yasm
option.
ffprobe and even ffmpeg with no output parameters run fine when reading
the file and wont crash.
The command line i used was:
{{{
./ffmpeg -i bbb-tr1000.ts -vcodec zlib -an asd.mkv
}}}
And this is the sample i used:
http://dirac.kw.bbc.co.uk/download/video/maybefinal/bbb-tr1000.ts
I'm attaching both the ffmpeg log file and gdb's output.
gdb mentions ff_add_rect_clamped_sse2 as the source of the problem, which
might explain why disabling yasm got rid of the crash.
