Re: [FFmpeg-devel] x265 rpu processing

[Robin van der Linden via ffmpeg-devel <ffmpeg-devel@ffmpeg.org>]

What list would you suggest instead, main?

The command was just a snipped, normally would do something like this:

/usr/bin/ffmpeg -i "/home/robin/dolby_vision_test_8_1 - [2160p].mp4" 
-map 0:0 -c:v libx265 -preset slower -ss 00:00:00 -to 00:00:10  -crf 20 
-vf zscale=3840:2160,hqdn3d=0.4:0.4:1.25:1.25  -x265-params

But ffmpeg returns the following for the command above:
