--- Comment #1 from Christian König deathsimple@vodafone.de --- Yeah, that is a known issue.

The current VA-API implementation waits for the result after sending a single frame to the hardware.

The OpenMAX implementation pipelines the whole thing and waits for a result after sending multiple frames to the hardware to chew on.

So with OpenMAX the hardware is always busy, while with VA-API it constantly turns on/off.
