mythfrontend eating cpu<BR></FONT><BR></DIV>
<DIV></DIV>I'm building my first myth box. I've got most of the stuff working
but I have this lingering problem for which I'd appreciate some
help.<BR><BR>Video playback is choppy, with lots of "prebuffering pauses". The
CPU is pegged at 100%, all of it on mythfrontend according to top. It's the same
whether I play live tv or a recording. If I play with mplayer instead (either
live on /dev/video0 or a recording made by myth), it's all smooth with the CPU
at < 10%, big difference ! Searching the archives, I found references to
possible sound problems, but I don't think that's the case here, I've tried to
cripple my sound artificially by pointing mythfrontend to an alsa device that
doesn't exist (and saying OK to continue with no sound), and the problem
remains, choppy video, high cpu (and no sound of course). <BR><BR>This is on an
up-to-date gentoo, amd64 (Athlon 64 3000), 512MB, sata drive, PVR-150, video
output to a CRT TV through S-Video on a cheap nVidia card. Latest nVidia driver
(81.78), gentoo ebuild for mythtv (0.18.1-r1 ).<BR><BR>Any clue where to look
?<BR>Thanks<BR> Vincent<BR></BODY></HTML>
