Pause and restart doesn't trigger it.
(Knock Knock Knock on wood...) my high CPU utilization problem seems to
have vanished. I wish I could pin down the source of it, since
mysterious vanishings have a way of becoming mysterious reappearances.
On another interesting subject. In checking this pause/restart out, I
noticed that my rebuffering messages happen at startup (initial tuning
of a channel) and channel change. Pause/restart eliminates the
rebuffering messages. Changing channels triggers them again, but
pause/restart cures it each time. Curious. I'm about to go research
whether these "rebuffering" messages are harmful or not. Maybe my
imagination, but I was thinking I saw "jerkiness" (not interlacing
artifacts) that perhaps corresponded to the rebuffering messages. They
seem to happen about twice/second, and I'm wondering if a rebuffer
corresponds to a dropped frame, corresponding to the jerkiness?
Also, if you're interested (Nick), I can document my current settings so
you can compare. For starters, I'm running nvidia 7676, mythtv
0.19-fixes, ivtv 0.4.2, ubuntu 5.1 with 2.6.15 kernel, an nvidia 5200
based card, bob deinterlace, 800x600 resolution, OpenGL VSync set in
mythfrontend and nvidia-settings. Lemme know if the relevant bits
correspond and whether you want any further details.
cheers,
john
