[mythtv-users] Problems setting up XvMC

[Greg 'groggy' Lehey]

I'm having trouble getting XvMC to start up.  Here's what I've done so
far:

- downloaded the sources from
  http://svn.mythtv.org/svn/branches/release-0-20-fixes/mythtv
- configured with --enable-xvmc
- set the preferred MPEG2 decoder to Standard XvMC (also extra audio
  buffering, as recommended at
  http://www.mythtv.org/wiki/index.php/XvMC).
- Create a file /etc/X11/XvMCConfig with the content
  'libXvMCNVIDIA_dynamic.so.1'

When I try to view a recorded programme, I get the following messages:

----------------------------------------

Tracing the frontend shows that it accesses the
libXvMCNVIDIA_dynamic.so.1 file (many times over), so it's finding the
library.  From googling, it seems that the "Init failed" message is
harmless.  Can anybody point me what to look at next?  I'm quite happy
to build with debugging code or just snoop around myself, if somebody
can tell me what I should be looking for.

Environment:

- FreeBSD 6.2-STABLE
- xorg 6.9
- nVidia GeForce 6200:

nvidia0: <GeForce 6200> mem 0xe4000000-0xe4ffffff,0xd0000000-0xdfffffff,0xe5000000-0xe5ffffff irq 19 at device 0.0 on pci2

nvidia0 at pci2:0:0:       class=0x030000 card=0x01301462 chip=0x022110de rev=0xa1 hdr=0x00
    vendor   = 'NVIDIA Corporation'
    class    = display
    subclass = VGA

- nVidia binary driver version 9631.
