I use ffmpeg and libx264 to gernate the out.264, I think it is the h264
stream, yes ffplay can play it ,and but not correct in some frames. just
like the log I paste in the previous mail. I want to ust ffmpeg first, but
it seems that the bug has exist for a long time.I serarch in internet, and
someone report the bug in 2011.
