[FFmpeg-devel] x265 rpu processing

Thu Sep 28 13:22:08 EEST 2023

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 
"aq-mode=2:aq-strength=0.8:early-skip=1:ref=4:me=star:subme=4:merange=64:rc-lookahead=5:wpp=1:strong-intra-smoothing=1:rect=0:rd=4:psy-rd=0.1:psy-rdoq=0.20:rdoq-level=2:rskip=2:bframes=4:b-adapt=2:analyze-src-pics=1:colorprim=bt2020:transfer=smpte2084:colormatrix=bt2020nc:hdr10_opt=1:master-display=G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,50):max-cll=2738,90:hdr10=1:chromaloc=2:dhdr10-info='/path/to/metadata.json':vbv-maxrate=2400:vbv-bufsize=4800:dolby-vision-profile='8.1':dolby-vision-rpu='/path/to/dolby_vision.bin'"

But ffmpeg returns the following for the command above:
