How about something like this, then? It adds a new filter to do the video processing, while leaving the scale filter as-is.
Implements denoise, sharpen and all of the colour balance controls; lightly tested but seems working on i965/Skylake.
Outstanding issues:
* The name is not very good, but I can't think of anything better.
* Needs more testing.
* Some error recovery is missing.
* Documentation.
* Reuses the surface pool from the input hw_frames_ctx - is anything going to object to that?
* Can't order the filters applied - does that matter?
* Sharpness + anything else aborts inside the i965 driver, other combinations work - should vaQueryVideoProcPipelineCaps() detect that, or is there some other way to get it?
Thanks,
- Mark
