[MPlayer-users] SDL/aRts audio driver fails

Thu May 16 20:30:02 CEST 2002

Okay, since nobody seems to know how to get aRts to work with mplayer, I
tried this:

I launch 'artsdsp esd' so it runs in the background.  Then I run
'mplayer -ao sdl:esd movie.avi' so mplayer plays through esd.  I can
hear sound when I do it this way, but the audio is almost a second
behind the video due to the caching of two sound servers.  But I guess
it's something I have to live with if I want sound to work.

I am still baffled as to why mplayer doesn't know how to direct sound to
aRts when I run it through artsdsp, while esd and any other program I
have that uses OSS has no problem with artsdsp.

Should I file a bug for mplayer and artsdsp?
