(This is a resend, since my join confirm hadn't gone
through yet.)
I have RTFM and googled for a couple of days now
trying to figure out this problem.
I have a Via EPIA ME-6000 mainboard (c3 600mhz),
256MB, with a g200-TV 8MB PCI card installed, gentoo
2.4.20, kde3.1.1, mgavideo 0.1.0. DMA is on.
I can capture using lavrec and play back the resulting
AVI file in lavplay with no problems. But when I try
to play back the same file in mplayer 0.9.0rc5, the
output is corrupt.
(Lavrec and MythTV hw MJPEG capture uses 20-30% of
cpu. Lavplay uses 100% of cpu but is smooth output.)
What I see in mplayer is: Every second or so the full
frame is redrawn, sometimes horizontally skewed, but
in the upper left of the screen, you can see the full
frame rate video (about 20 pix high by 100 pix wide)
is playing. Just to the right of this (same 20pix
high) it starts to look like garbage that is changing
very quickly. It looks like it's playing all the data
but it keeps getting corrupted.
CPU is only 40% or so while this is happening, so that
shouldn't be a problem. I've also tried various screen
depth and size settings.
The reason I want to figure this out for mplayer is
that I see the same output when I use hw mjpeg output
in mythtv 0.8. I'm hoping someone can point me in the
right direction.
Could this be a problem with Xvideo or ffmpeg? mga or
mgavideo? (I saw one post on ffmpeg-devel that sounded
similar, but of course no helpful responses).
If I do mplayer -no xv, I see the same problem, so
maybe it's not xv. I have also tried various
decimation/quality settings in lavrec, same problem on
playback in mplayer.
I am not trying to do TVOUT (yet; figure one problem
at a time is enough).
Any help would be greatly appreciated.
Thanks.
