[ubuntu-mythtv] XvMC gone

[Mario Limonciello]

Eloy:

You're the first person to raise any concerns about this.  Also the first
person I've heard in that XvMC actually functions on 0.24.  My understanding
is that it's only stable with the older NVIDIA drivers.

With how frequently the crash reports were coming in, it sounds like you are
certainly in the minority.

Unfortunately autobuilds are temporarily disabled due to upstream's switch
to git.  We were staged and ready to switch as well, but they changed the
organization last moment so our strategy must be modified.  So even if we
were going to revert the XvMC disable change, it couldn't happen until
autobuilds were re-enabled.

As much as i'd love to make everyone happy, I'm currently leaning on keeping
XvMC off.  Once autobuilds are re-enabled, I would be glad to help teach you
how to set up a local autobuild repository based off of all of our packaging
scripts and what not however so that you can still have XvMC enabled builds
for yourself on 0.24.

Thanks,
