[FFmpeg-devel] [PATCH 0/3] V5: VAAPI: Add high bit depth encode/decode support

This changeset fills in support for the remaining high bit depth
formats the VAAPI exposes. This requires adding more weird Microsoft
pixel formats and then mapping them in the VAAPI code. I've also
enabled hw mapping between VAAPI and vulkan for sufficiently simple
formats.

V5: Switched to using alpha-less variants of Y410 and Y412 (called XV30
    and XV36 in libdrm) to avoid forcing the overhead of alpha handling
    in situations where it can't actually be used.

Philip Langdale (3):
  lavu/pixfmt: Add P012, Y212, XV30, and XV36 formats
  lavc/vaapi: Add support for remaining 10/12bit profiles
  lavu/hwcontext_vulkan: support mapping VUYX, P012, and XV36
