this sometimes causes a crash with
ffmpeg -f lavfi -i testsrc -vcodec libxvid -vframes 2  out.mov

the crash is in xvid but it doesnt crash before, its also occuring
only sometimes i had not been able to reproduce under gdb or valgrind
so i dont really know what to make of it ...

the probably useless backtrace i have:
/usr/lib/x86_64-linux-gnu/libxvidcore.so.4(+0xeb27)[0x7f0849264b27]
/usr/lib/x86_64-linux-gnu/libxvidcore.so.4(+0x13e5a)[0x7f0849269e5a]
libxvid.c:0(xvid_encode_frame)[0x9ef601]
libxvid.c:0(xvid_encode_init)[0x453961]
