[FFmpeg-devel] [PATCH 3/3] lavc/vaapi: Switch preferred 8bit 444 format to VUYX

[Philip Langdale <philipl@overt.org>]

As vaapi doesn't actually do anything useful with the alpha channel,
and we have an alphaless format available, let's use that instead.

The changes here are mostly 1:1 switching, but do note the explicit
change in the number of declared channels from 4 to 3 to reflect that
the alpha is being ignored.
