[MPlayer-users] Mplayer oss Mixer error. sound output isn't smooth in time to play file.

[KJ YOO]

I played MP3 Files by Mplayer.
My Mplayer binary is compiled arm-linux (arm926ej-s)
I ported to my embeded board.
It's davinci dm6446. but I don't want to use dsp codec.
Anyway I successfully complied mplayer.

but mp3 playback sound is very bad.
Although I used libmad, It's has serious delay.

What can I do?

It's Mplayer execute log...
