OK, I will recover other comment blocks except those in the function optimizatized by this patch. ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel

I am optimizing performance of various media codec libraries for loongson platform, and some progress has been made on libvpx and ffmpeg projects. ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel

Sounds great.
