I am almost desperate with my MythTV.
I have installed Knoppmyth 5.5 on a Via Epia Me6000 Mainboard and I need to
use the onboard chipset CLE266 for video acceleration.
I also did lots of upgrade using apt-get upgrade.
I have also installed xserver packages of openchrome. In my xorg.conf I start
the driver in section "Device" with "openchrome"
This all works as I have a perfect working DVD-playback with
:~>xine -V xxmc dvd://
Unfortunately my Mythfrontend obviously does not use the hw acceleration
although I have tried different selection in the tv output configuration.
I have tried XvMC as well as Via-XvMC.
As video renderer there is xvmc-blit available but when I start whatching
TV/recording I receive messages like
> VideoOutputXv: Desired video renderer 'xvmc-blit' not available.
> codec 'None' makes 'xv-blit,xshm,xlib,' available, using 'xv-blit' instead.
But the fall back renderer obviously does not support hw acceleration. (High
CPU load, choppy video)
I did some research in the internet and I found that this might be an issue of
the new in Mythtv version 0.21 (which I have installed)
~$ mythfrontend --version
Please include all output in bug reports.
MythTV Version : 17686M
MythTV Branch : branches/release-0-21-fixes

using_xrandr using_xv using_xvmc using_xvmcw using_xvmc_vld
using_bindings_perl using_bindings_python using_opengl using_ffmpeg_threads
My (urgent) questions:
- which renderer is the right one to pass video out through CLE266? When I
tried any other renderer offered in the Mythtv settings, I received a very
choppy video Sad
- how can I fall back to Mythtv 0.20 instead (using apt or a deb-package)?
- Do I need to recompile 0.21? But how ?
Thanks for help
I have already posted this to two forums (mysettopbox.tv
and .mythtvtalk.com/forum) but there are only few views and no replies so far
to this tricky issue ...
