[FFmpeg-devel] [PATCH 2/2] lavc/vaapi: Add support for remaining 10/12bit profiles

Philip Langdale philipl at overt.org
Sun Aug 14 00:18:21 EEST 2022


With the necessary pixel formats defined, we can now expose support for
the remaining 10/12bit combinations that VAAPI can handle.

Specifically, we are adding support for:

* HEVC
** 12bit 420
** 10bit 422
** 12bit 422
** 10bit 444
** 12bit 444

* VP9
** 10bit 422
** 10bit 444

These obviously require actual hardware support to be usable, but where
that exists, it is now enabled.

I had to make some adjustments to the encode logic for matching bit
depth as the existing code assumed that the picture depth and the pixel
format depth were always the same, which is not true for 12bit content
which uses 16bit pixel formats.
