Tvheadend

Hi,

My question is a generic one, and not so much directly about tvheadend but related: I am using the transcoding-branch of tvheadend to stream to android; Now, transcoding is a cpu-intensive task, and I read that you can use the gpu for hardware accelerating the proces.

Can someone give some insight in how this might be achieved or how this might work ?

My system is a headless A6-3500 Llano processor based server (with build-in Radeon Graphic).

Some specific questions might be:
- Is it possible to use the onboard graphics of my A6-3500 for hardware acceleration ?
- How should I do this: I installed the graphics drivers (ati-drivers), but this seems to make no difference on the CPU load.
- FFMPeg is compiled with vaapi and vdpau support, is this needed? (I guessed it is, but again, no apparent difference in CPU load).

- Also, how can I check on a headless server if the video-drivers work correctly? (f.e.: using "fglrxinfo" gives an error, cant open display)

Any pointers/links/refs as to where to look would be appreciated.

Thanks,

Alex.
