BRAWSource plugin for Vapoursynth & Avisynth

[ChaosKing]

Uses the Blackmagic RAW SDK to decode audio /video files.
Supports Windows, Mac, Linux. It's a dual plugin, works in Vapoursynth / Avisynth. Every usefull information is exported as frame props.

It's an AI created plugin, took about ~4h to build. For fun and Ai tesing.

Works great on Linux :D

Vapoursynth: pip install vapoursynth-brawsource
Avisynth: extract the release into your plugins fodler

Please test and report back if it works on your machine or something is missing.

The SDK has GPU support, not sure if it's really faster in vs/avs context.
It supports 3 Pipelines — CUDA (NVIDIA), Metal (macOS) und OpenCL. CUDA only is enough?

EDIT:
clip: Mountains.braw 6048x4032 290 frames x4
best CPU: 25.8 fps best CUDA: 26.2 fps speedup: 1.02x

Raw decode performance in cuda is 5x faster (200+fps) - moving frame data between cpu<->gpu is expensive
Mac could be much faster with its Unified Memory.

Well that's pretty dang cool to see. And cheers to another Zig plugin!

v0.2.1-beta is out https://github.com/theChaosCoder/vapoursynth-blackmagicraw-source/releases
- much faster 8bit decoding
- gpu support metal & cuda (still room for improvement)


A 6K Video decodes with ~200fps (metal) on my m1 Macbook vs ~80fps (cpu)
Same Video with CUDA on RTX3080 ~175fps


Todo: Pypi release

[ChaosKing]

v.0.3.1
- GPU optimizations
- You can now install via pip install vapoursynth-brawsource
- v3 builds (AVX2)

It would be nice if someone can test the avisynth plugin. I only tested this in a vm.
