I wrote up some notes which may complement what you've already found on this
thread & wikis...
Note, I probably didn't have to compile in VDPAU support but only found
VDPAU was missing on my Ubuntu system when I tried to compile and found it
wasn't pulling it in... and the system was missing VDPAU libraries... as a
result video playback was awful until VDPAU was enabled and the system
stopped using the main CPU.
"Include libvdpau1-dev is installed (otherwise no VDPAU compilation
possible). This wasn’t included in my default installation." (Default:
I've also got some imperical notes on VDPAU profiles (Slim, Normal etc). I
ended up editing the pre-configured profiles you've found and watching
playback. For my HW I could only really get Temporal 1X to work, with an
ION 1, and I suspect with the more recent ION 2 chipset you'd have better HD
My post also has some logs which other mythtv-ers were able to browse and
critique possible issues with my setup. If you can collect them I suspect
you'll narrow down your problems quickly as the logs are very verbose.
Hope this helps, I know its not exactly a plug-and-play experience.
