2008-10-31 06:56:01 decode h.264 by mplayer
Wei Jiang (CHINA)
We tested mplayer to play an H.264 file on 640x480 LCD. The video is encoded in CIF at 500kbps.
./mplayer -nosound -vo fbdev -sws 0 -vf scale=640:480 1.mkv
We found the video output is about 5fps.
And 12 fps with no resize;
I know that mpeg4 decoding is very fast. Why h.264 decoder is so slow?
Any advice would be greatly appreciated!

H.264 uses a slightly different video codec than mpeg4 - mpeg4 has received more optimization than H.264 right now inside ffpmeg.
