Subject: [FFmpeg-devel] FFV1 slicecrc: "hashxx" instead of "CRC" for speed?
Date: Tue, 25 Oct 2022 22:31:48 +0200
Message-ID: <2b7f9605-518a-4cda-6503-7842f22fa620@das-werkstatt.com> (raw)
Hi everyone :)
This is merely a question of interest. Not a request, complaint or
trolling of any kind :)
I'm happy about any answer. I'm curious.
Would it possibly have a significant impact on coding speed of FFV1's
slicecrc option (Where a CRC is calculated for each frame slice), to use
a faster algorithm instead (if one exists)?
I'm wondering if, for example something like "xxHash" may warrant a try?
(Haven't found CRC vs xxHash benchmarks yet, but I'm still looking)
Anyhow,
Thanks for any of your time :D
