VRChat UdonSharp decoder implementation #67
Description
This is a limited implementation and has a few differences to the spec to improve decode performance, due to the incredibly tight performance constraints in VRChat's Udon runtime, but I have posted a sample decoder at https://gist.github.com/TapGhoul/bc7f0d9095aebbc2ef6f766ee1a56586
The changes have been documented in a bullet list in the README.md in the gist.
While this is a bit of an insane implementation, I think it'd be cool to show off purely for the sake of demoing the performance of the codec under constrained environments.
This is a ground-up rewrite to C#. A proper C# impl would want to use different primitives in some areas, but concessions had to be made to get realtime decode performance.
As this deviates a little from the standard format, I'm not sure if it should be listed, but it is a decently well documented and fairly easy to read implementation of the decoder side of the codec.
The decoder can be seen in action in the gist, but here's a video of it in use:
