thanks for your reply.
i have ported mplayer to my mobilephone which runs android based armv6.
but the performance is too bad,and i found yuv2rgb take a lot of time .
the only reanson of using "-vf format=yv12" is making mplayer output
i can implement the colorspace conversion by some more optimized
than "sws_scale".is this idea correct to improve performance ? another
found any promotion except the distortion after use -framedrop.are there more
suggestion to improve decode performance on arm platfrom ? thanks!
