[Openchrome-users] Xvmc fails ( memory allocation error corrected)

[R. G. Newbury]

Quickly: how can I test to definitively determine whether xvmc is 
working properly?

Via SP13000 running Fedora 6, openchrome svn 320, latest drm, mythtv SVN 
13339.

Update:

The memory allocation error bug was squashed by upgrading to openchrome 
SVN 320 and the latest git drm. Compile and installation was exceedingly 
smooth...

However, the underlying problem remains. I get washed out colors, with 
streaks of blue or red across the screen, and a bright flourescent 
stripe of green across the bottom of the screen.

Searching the mythtv archive for that symptom revealed a thread from 
last summer which diagnosed the problem as being 'xvmc not running'....


As noted yesterday, I think I have all of the right things in the right 
places, and xvmc should be running.... In fact, I am completely unable 
to understand what could have changed, as I have not upgraded the OS on 
the box since the middle of last year. The openchrome driver I had been 
using was one of Xavier's rpms from the same period. The Xorg.0.log and 
dmesg show absolutely nothing wrong.

But it appears that xvmc may not be running. Myth reports no errors, 
although Via xvmc is the selected decoder.

Even more intrigueing, I now have 2 programs recorded last night, *on 
the same channel* and using the same HDHR tuner, where the first program 
(ER) shows the problem, and the second (Grey's Anatomy) does NOT. There 
were no changes to the OS throughout the recording period... I just let 
the machine record without installing anything while it was busy.

I forgot to check whether the OSD in the latter was colored or grey. But 
the OSD on any of these that show the problem are in blue.

The problem occurs on both PVR500 (internal) and HDHR (external) tuners.

I *suspect* that myth is the problem as this started just when I 
upgraded from myth svn 12618 to SVN 13339 but I am not sure of this, and 
in fact, it is hard to believe that myth would/could degrade this way 
without it being noticed.

(Will attempt checking with xine or mplayer).

Quickly: how can I test to definitively determine whether xvmc is 
working properly?
