Ice Lake hardware deinterlacer test

[sophisticles]

I have finally gotten around to testing Ice Lake's hardware deinterlacer and here are the results. I encourage someone to post a test with qtgmc or whatever all the kids are using nowadays.

The test source can be found here:

The test was done on Manjaro running on a HP laptop that uses a i5-1035G1 and these tests were done via Avidemux.

I tested all available vaapi deinterlacing modes, in both regular frame rate and double frame rate, and I tested with both x265+medium+crf 20; for vaapi I used Intel's hevc but Avidemux does not allow setting quality setting, just a max of 4 b-frames, a max of 250 gop and either bit rate based or "crf", which I used set at 20.

Thoughts are welcome.
