[x264-devel] about H264 decoder of libavcodec

[坚 吴]

Dear friends,
    I compressed foreman.cif as out.h264 with x264 encder.After I download ffmpeg -0.4.9-pre1,I uncompressed out.h264 with H264 decoder of libavcoder by the command line "./ffmpeg -i out.h264 264dec.yuv".
    I don't modify it anywhere.In this default case,I try to read where are optimized by mmx/sse/sse2 of this H264 decoder.But in this case,I couldn't find the optimized positions.I consult how open the optimization --mmx/sse/sse2 in H264 decoder.

    thanks
