Problems with X11Amp

Problems with X11Amp

[@ 2000-01-11 14:46 UTC (permalink / raw)]

Hello All

I have been trying to use X11Amp as MP3 player. When my machine is under little or no load, the player works fine, but when it is under high load, the player seems to lost syncronism, and starts to make noise like that of a radio when no station is tuned on. To make it start again, I have to try to play the osng again many times until it works back again. Can some one tell me what is going on?? Can I prevent this??

Thanks for your help, and sorry for my english

1) Use XMMS instead. X11Amp became XMMS, and X11Amp is no longer supported.
2) It takes a lot of CPU cycles to decode MP3's.  If you run a lot of
   stuff while listening to an MP3, it's going to sound horrible.

...unless you use Linux 2.2 + the lowlatency patch, and sets the mp3
player thead to SCHED_FIFO. That makes the player run as a true hard
real time task, ie it will never drop-out, and it'll just take the
CPU time it needs. (Provided your CPU is fast enough, obviously! :-)

In case you have missed it, see

	http://matrix.crosswinds.net/~linuxmusic/lowlatency.html

It seems like a refined version of the lowlatency patch is going into
the mainstream 2.4 kernels... (Cutting scheduling latencies does
bring advantages in other areas than real time processing as well.)
