Both VA-API and VAAPI stands for Video Acceleration API, h264_vaapi in FFmpeg is

Currently, create_pnext is only used if an applicable external memory
extension is enabled. This will usually the case when used from the command
line, but may not be when the Vulkan context is created manually.
For images used in video decoding, create_pnext contains the video profile

For the FFmpeg meeting, of course. For the rest, I dunno yet.

Neon RGB24->YUV420P and BGR24->YUV420P functions. Works on 16 pixel
blocks and can do any width or height, though for widths less than 32 or
so the C is likely faster.

Add simple C functions for converting XRGB to YUV420P. Same logic as the
RGB24 functions but dropping the A channel.

Allow odd widths for conversion it costs very little and simplifies
setup slightly. x86 asm will fall back to the C code if width is odd.
Round to nearest rather than just down. This reduces the Y error
reported by tests/swscale from 3 to 1. x86 asm doesn't mirror the C so
exact correspondence isn'
Add a rgb24->yuv420p conversion. Uses the same code as the existing
bgr24->yuv converter but permutes the conversion array to swap R & B

Rename swscale conversion functions for converting BGR24 frames to YUV
as bgr24toyuv12 rather than rgb24toyuv12 as that is just confusing and
would be even more confusing with the addition of RGB24 converters.

-bitexact as a general flag doesn't affect swscale so add swscale option
too to get correct CRCs in all circumstances.

This patch set expands the set of dedicated RGB->YUV unscaled functions
to help with encoding camera output on a Pi. Obviously there are other
uses but that was the motivation.
It enforces the general bitexact path for the fate tests that depend on
it.
It renames the existing bgr function as bgr..
