New submission from John Stebbins <[email protected]>: I am transcoding a file to mpeg4. When enabling threads and b-frames, the resulting output has errors. If I disable either threads or b- frames, the output is good.
Command line: ./ffmpeg -v 9 -loglevel 99 -i ~/Bubblegum2-r3803.mp4 -bf 3 -threads 12 - vcodec mpeg4 test.mkv When played with mplayer, I get these errors: [mpeg4 @ 0xd175c0]illegal MB_type [mpeg4 @ 0xd175c0]Error at MB: 853 [mpeg4 @ 0xd175c0]concealing 0 DC, 0 AC, 0 MV errors Log is attached.
