<pre wrap="">I, too, took the time to get XvMC working on my
7300. I was able to follow
the directions in the wiki, and after using envy my
CPU usage decoding ATSC
HD is now officially in the cellar! (...that's a
*good* thing. :) Also
lets me know XvMC really *is* working!)
However, the OSD is in greyscale. I tried adding
Section "Device"
...
Option "UseEvents" "true"
Option "XvmcUsesTextures" "false" (necessary
for color Chromakey OSD)
Option "NVAGP" "1" (some users report 2 works
better, may not be
applicable to newer driver versions)
EndSection
to the xorg.conf and restarting X... no effect.
I tried switching from xvmc-blit to xvmc-opengl, no
effect. Though looking
at the frontend log, I'm not surprised:
2008-04-15 17:51:53.115 VideoOutputXv: XvMC Adaptor
Name: 'NV17 Video
Texture'
2008-04-15 17:54:15.534 VideoOutputXv: Desired video
renderer 'xvmc-opengl'
not available.
2008-04-15 17:54:18.342 VideoOutputXv: Desired video
renderer 'xvmc-opengl'
not available.
codec 'MPEG2 IDCT' makes
'xvmc-blit,' available,
using 'xvmc-blit' instead.
I tried switching from chromakey to opengl for the
OSD renderer, no effect.
(But that's not really surprising, since xvmc-opengl
isn't available,
switching the OSD renderer shouldn't do anything.)
And yes, in the frontend logs, I get complaints
about chroma keying being
unavailable:
2008-04-15 17:55:09.079 VideoOutputXv: Ack!
Disabling ChromaKey OSD
We can't use ChromaKey OSD
if chromakeying is not
supported!
So it appears as though the tradeoff is a B&W OSD
with XvMC, or doing
without XvMC alltogether. And XvMC-openGL appears
to be a non-starter.

Thanks, I had a feeling I wouldn't be able to get
color OSD to work with the 7300. I would use the grey
one but on standard def the OSD resolution is messed
up so it's hard to read the OSD. I found a work around
though as I setup a match criteria to use standard
ffmpeg at standard def and XvMC at high def so only on
a few channels do I get a grey OSD which is worth it
since the xvmc performs much better. Thanks for the help.

You can also try using a different OSD theme. You can change the OSD
theme independent of the regular MythTV theme. I have found that retro
is much easier to read. I use that for my OSD theme and it works great
in color and in grey.<br>
