[mythtv-users] MythMusic visualisations

[Christopher Briere]

Anyone ??
I've searched the archives and I found nothing. So, if I missed
something, flame me away, but otherwise could someone help me figure
this out ?

Thanks

Hello everyone, 
I've been running quite successfully the whole "mythtv suite", but there
is one thing I never could figure out, so I finally decided to subscribe
to the list and ask this community.
It concerns Mythmusic. I'm running everything on a celeron 2.3ghz, 768mb
ram gentoo box, and I use the ebuild releases exclusively. In mythmusic,
the visualisations work, however, they "stutter", i.e, one second they
are smooth, the other they come to a crawl. And while this happens, X
takes around 70% of the cpu time. I initially thought it was an opengl
issue, but a simple glxgears test showed that is was not (920 fps for a
radeon 7500) So I started to look elsewhere. I discovered that when I
hit pause, the visualizations DO run smoothly (I use "gears" because it
is the easiest to check upon) but as soon as I resume the playback, same
things happen and cpu load rises again.
I remotely ran Mythtv/Mythmusic through X11 on my macintosh and the
display is smooth indeed, thus telling me even more that the problem
comes from the mp3 decoding.
So since I have mp3 files exclusively, I think the problem comes from
MAD. I tried recompiling libmad with the speed flag, switched back to
using MAD, compiled both with --march=pentiumpro, but no progress.
So I turn out to you. I stumbled across this thread in the archive

h_string=MYTHMUSIC%20HOG;guest=1492917&t=search_engine#61917
but I'm still struggling to find the solution. 
Any insight/comments/help is much appreciated. 
Cheers 
Christopher
