[FFmpeg-devel] [PATCH 0/3] v2: vaapi: switch 8bit 444 format to VUYX

[Philip Langdale]

After discussion with Mark, I'm switching the preferred format for 8bit
444 content in vaapi to VUYX, which is the alpha-less variant of VUYA.

This format is formally supported by the driver, so we don't even need
to do any fudging.

I am not removing VUYA because we found another use for it, replacing
the previous requirement to use v408[enc|dec] to work with it.

* v2: Fix test update in wrong change
* v3: Remove incorrect alpha flag from pix_fmt
