I have source to a mplayer which uses the MFC/PP as the video codec for the
four video encodings it supports. A hd video with MFC decode utilizes ~30% of
the 6410 and without the HW assist utilizes all the CPU and still drops
frames. This is all within Xwin using the fbdev.
This MFC/PP driver pair is useful to users now. I am sorry they are not
good enough for the next-s3c.
