> Hello,
> I am trying to use avcodeclib for HD MPEG2 encoding (720p and 1080i). Single threaded encoding works ok. But when I switch to multi-threaded encoding (4 threads) I get crash on 3rd call to avcodec_encode_video. I used GDB to find the address of crash and it is in "avg_no_rnd_pixels16_xy2_mmx + 94".
> Any help in this regard will be greatly appreciated.
> P.S. I am already using multi-threaded decoding perfectly using same libs. My platform is Win32 and I have compiled using MinGW.

Try a newer version of GCC.
