Yes, it’s finally been released after cooking for so long in the svt-av1-psy fork!
I know everyone is really excited about this. If I’m using ffmpeg, how do I use it (once ffmpeg merges this update)?
Compile FFmpeg with the SVT-AV1-PSY fork
That’s it? I don’t need any arguments or options when I do the transcode?
This adds several new options to the SVT-AV1 standalone encoder (
--enable-variance-boost,--variance-boost-strength). I notice that, by default, variance boost appears to be turned off.To use it with ffmpeg, you’d likely need to explicitly enable variance boost in the source code where ffmpeg applies the config options to the svtav1 encoder.
For testing, it’s probably easier to run the standalone
SvtAv1EncAppwith aforementioned parameters and pipe ffmpeg’srawvideooutput to it. Either way, I assume this functionality will eventually become an option for ffmpeg’s-svtav1-params, now that it’s in the SVT-AV1 main tree.Disclaimer: this is just what I concluded from a quick check of the patch and ffmpeg code.
