[mythtv-users] XvMC and the OSD

[Jeremy McDermond]

I hope this isn't information that's already out there, because I  
just spent a few hours pounding my head against the wall and sorting  
through the mplayer and mythtv code after looking for enlightenment  
on google, the wiki, and gmane.

The Greyscale OSD in XvMC hack on the Wiki (http://www.mythtv.org/ 
wiki/index.php/XvMC) also fixes a problem where the X server will  
simply refuse to use XvMC.  This is with an NVidia FX5200 on both the  
7676 and 8178 NVidia drivers.  I'm using mythtv SVN revision 9154.   
Here are the errors that pop out of mythfrontend:

2006-02-26 03:24:44.878 XvMCOSD::CreateBuffer() failed on  
XvShmCreateImage

Buffers.

Note that mplayer also has issues when it calls XvShmCreateImage, but  
I haven't explored how to fix it yet.  I hope this may help someone  
who encounters the same problem.
