I have had a sync problem in LiveTV/recordings for some months now.
I always belived that it was a ivtv problem, and tried older versions
without any luck.
Yesterday i took the time to try to investigate what was the cause of the
Strangely as far as i could understand, it was MythTV that was the cause of
So, what happened and what did i try?
I did go back to ivtv-0.3.3 and used "mplayer /dev/video0" to see if i had
Well, i could show TV, but only one time, and MythTV did segfault and failed
LiveTV some times, so i guess MythTV didn't like that version. But mplayer
So i moved on with the versions of ivtv. Using mplayer everything was fine,
still didn't like older ivtv versions. But i was a bit confused that mplayer
worked. I'm sure i have
tried that before.
Finally i installed the latest stable ivtv, version 0.4.2, rebooted and
tried mplayer. Video/audio
was smooth as a baby. And i knew MythTV could start LiveTV with this ivtv
i started MythTV and LiveTV, and the stuttering began.
I quit MythTV and tried mplayer again, and now the stuttering was there too.
ivtv-0.4.2=>rebooted system=>mplayer == works perfect.
If i start LiveTV i get stuttering, even after quitting MythTv and trying
mplayer again, need to
reboot to get TV smooth again.
Sure, it could be something with my system that is wrong. But it feels
strange that when running
LiveTV the problem begins, and i can't get rid of them without rebooting.
All this was tried with MythTV0.18.2 and the SVN version as of yesterday.
I have tried various settings in the Playback, audio buffering, realtime
priority and everything else
i could think of.
There is no abnormal CPU usage, about 45%, and no peeks when the stuttering
I have a PVR-250 tv-card.
I was waiting for someone else to have this problem, but it seems that i'm
the only one?
I won't put this in trac because i will only get a "works for me=>closed"
But maybe someone with a little more knowledge about linux and mythtv can
help me to find
out why i have this problem. Is it my system or MythTv?
Don't really know what more information could be needed to help me, but i
submit my log
from a session and maybe someone could se the problem there. I used
"mythfrontend -v playback" for this log.
