[FFmpeg-devel] [PATCH] avcodec: loongson3 optimized h264dsp weighted mc with mmi

[周晓勇]

i am working on debuging the two patchs i send u before.
mpegvideo patch has two incorrect functions which cause failures in fate-vsynth1(2)-mpeg2(-422).
i will repatch the mpegvideo optimization fist after resolving the bugs.
thanks.
