no support for via XVMC

[LAL018]

Binary package hint: mythtv

Mythbuntu 8.04

via XVMC does not get detected. In the frontend log the following may be read:

2008-03-08 04:01:41.910 AFD Error: Could not find decoder for codec (MPEG2VIDEO_XVMC_VLD), ignoring.

Perhaps due to openchrome name change.

Have you tried installing the GStreamer codecs?

[laga (laga)]

MythTV does not use gstreamer.

For completeness I want to add to this bug report, that this also occurs with the MPEG2VIDEO_XVMC coded (the non-vld one)

[Mario Limonciello (superm1)]

If it's happening to MPEG2VIDEO_XVMC, you have configuration issue - I have
this one working -

I've got a fix in mythtv bzr revno 71. Should upload within a day or two.

[Huub Bouma (bouma-w20e)]

I used to compile mythtv from svn (but I was still on the 0.20 version)
but a couple of days ago decided to go for the ubuntu packages (0.21)
Since then the xvmc (nvidia) doesn't work anymore for me. So my guess is that the MPEG2VIDEO_XVMC codec isn't compiled into the mythtv package.
Since it worked for me before this upgrade, and I followed the steps in the XvMC mythtv wiki, I don't think this is a configuration issue. But should the xvmc be in the package, or should I build from svn?

The wiki states the following:

=============
 The following binary linux distributions support XvMC out of the box:

    * Mandrivia 2006 Free
    * Debian
=============

So I guess that this answers my question... Ubuntu doesn't support xvmc?

This is the logging from mythfrontend just before the crash:

Ubuntu supports XvMC. For NVIDIA XvMC, I use it *myself*. Make sure you aren't
enabling multiple cores for the XvMC decode. It only works with one.

That did the trick! The number of cores to be used had a value of 4. Setting it to 1 did the trick! Thanks for the tip. I will add it to the xvmc wiki
