Question Does Unity have a compression API?

Seeing how many things can be compressed in so many ways (Gzip, LZ4, Brotli, etc. etc.) within Unity, it baffled me that I couldn't find any built-in API to hand over a byte[] and have it returned in a compressed format.

Not even the in-development packages like Collections and Serialization have something like that (with the exception of "packing").

Currently I just use .NET's GZipStream but I'm wondering if there's anything in the Unity-universe that's also readily available?

... and it needs to have a permissive license - not looking for asset store assets. But internal methods or github repositories with license are okay. I know ZipSharpLib but I was really hoping for something bursted & jobified.

 

There was this recent thread:

I found this delta compression algorithm which references this LZ4 algorithm for .NET. Here’s the Odin extension for it. LZ4 trades compression efficiency for speed.

Since Unity provides LZ4 and LZ4HC as build compression options I'm pretty bummed that there isn't a public API available for this. I mean it's super-simple take some bytes and return some bytes stuff ...

 

https://learn.microsoft.com/en-us/d...ompression.ziparchive?view=netframework-4.5.2 plain old zip. Works with streams, easy to convert from/to bytes.

 

Nice one - available in .NET Standard 2.1 as well.

I recall that someone said rgba or so created issues in newer versions..there was a related post on the forum somewhere from someone who used my example and updated it…can’t remember
