Pipelines are just shaders. There's no reason to treat them
differently.
This also lets us implement shader objects and is an overall
cleanup.

It seems quite different from the format you sent.
Top-posting isn't exactly liked here, though I don't really have a
strong opinion on it.
Apologies, as I'm still relatively new to the FFmpeg community and have a

Any additional guidance would be greatly appreciated.

This commit implements a standard, compliant, version 3 and version 4
FFv1 encoder, entirely in Vulkan. The encoder is written in standard
GLSL and requires a Vulkan 1.3 supporting GPU with the BDA extension.
The encoder can use any amount of slices, but nominally, should use

Could you apply this to ffv1enc_vulkan.c as well? It uses the same
quantization table
that the software encoder initializes, as well as the same option
