I'm having trouble playing videos on the BF548 EZ-Kit. I have loaded ucLinux onto the board, and am using mplayer to play an mp4 video. It plays, but the framerate is very low, probably <1fps. Also, the audio is really laggy too, since the video doesn't play at the full speed. The display attached to the board is what's listed in the manual:
Sharp LQ043T1DG01 – 480 x 272, 4.3” touchscreen LCD
Analog Devices AD7877 – touchscreen controller
As far as I know, I have the video drivers enabled in kernel. I have also noticed that when changing settings with alsamixer, the text is pretty corrupted in the mixer, but I am communicating with the board via serial, so maybe it's too slow for it to work properly...
I'm running the 2010 RC1-RC5 kernel release.
So what I'd like to know is, how can one play videos properly on the BF548? Should it just work "out of the box" once a video player has been installed, or do I need to configure some other things as well? I'm completely new to doing things on the BF548, so it would be appreciated if someone could help.
