I.e a limited 256 colours OSD engine ?
If you want to use your computer with any regular application, you'll
then can't use the video display provided by this decoder.

To my understanding, VaAPI is not in charge of displaying video.

What you basically have to do is:
- make FFMpeg uses VaAPI (this is generic, not related to your card in
particular)
- implement a video driver (hw specific) towards libVA (no idea if it
is kernel or user based though, need to check this out).
