Zstandard

Post by Betabot »

I recently added a version of ZRLE that uses Zstd instead of zlib compression to my own vnc software. The two compressions are not compatible so a different encoding number is used, but with minimal changes to the code I got both better compression ratios and lower cpu usage (both compression and decompression).
Zstd is licensed using the BSD license: https://github.com/facebook/zstd

edit:
I added Zstd to my local UltraVNC branch and could provide a patch if anyone is interested.

@Betabot: Where is your code?

UltraVNC is now on GitHub, more easy to work on the code...
