[Libva] Will the intel-driver VPP support motion-adaptive deinterlacing on SNB/IVB?

[Simon Farnsworth]

Hello,

We're attempting to use VA-API on Intel Gen 6 and Gen 7 hardware to replace software 
decoders, and we're hitting quality issues with the VPP deinterlacing support. Our 
CPUs range from Celeron 847 (low-end SNB) to Core i3-3220 (mid-range IVB).

Specifically, it appears to only support bob deinterlacing, which on the common "ticker 
tape" horizontal scrolling text used on news channels looks awful (you can see the 
alternating fields bob up and down.

The description of the deinterlace algorithm in the public SNB documentation, volume 
4 part 1 section 2.8, suggests that the hardware is capable of motion adaptive 
deinterlacing to get better results. Will this be enabled in the intel driver at some 
point?
