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 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
