MP3 playback skips during high disk IO (from other processes). It would be nice if JuK buffered a portion of the MP3 (or all of it) so that disk IO isn't an issue.
Comment 1 Scott Wheeler 2004-04-02 12:53:21 UTC
JuK doesn't handle MP3 playback -- that's handled (including the buffering schemes) completely by the backends.  You can adjust the buffer size for aRts in KControl however.
Comment 2 Stefan Gehn 2004-04-26 17:38:29 UTC
1. Make sure your buffer setting for artsd is not too small
2. Enable realtime-priority for artsd
3. make sure the "artswrapper" binary is setuid root (2. only works with that one, sane distros should do that automatically though)
4. OPTIONAL: Hack mpeglib to use bigger input buffers, I still have to ask somebody if we can bump the buffer to at least 2-4x the size it is now
with all these changes it's quite hard to make noatun, juk or amarok skip if you have a semi decent system.
