[ubuntu-mythtv] VAAPI for Intel Atom Cedar trail chipset

[JASON HOLT]

I am running MythBuntu 12.04 (32 bit) with an Intel Atom DN2800MT motherboard (Cedar trail chipset.) I installed the cedarview proprietary drivers using apt-get and 1080i OTA video works great, but the CPU usages is ~33%

The proprietary bundle included a VAAPI driver, so I read the how-to at www.mythtv.org/wiki/VAAPI and assumed that since the driver was installed, I could skip step 3 (complling the driver). I followed all the other steps, but after setting up the VAAPI playback profile, the same videos will not play. I receive the error "Failed to open video output."

mythfrontend --version shows using_vaapi
 
The following portion of the mythfrontend.log appears noteworthy...

Sep 6 15:05:04 mythbox mythfrontend[1815]: E CoreContext mythplayer.cpp:2675 (StartPlaying) Player(0): Unable to initialize video.
 
Should I not have skipped step 3?
 
Any ideas?
