[FFmpeg-devel] x265 rpu processing

[FFmpeg-devel] x265 rpu processing

[Robin van der Linden via ffmpeg-devel]

Hello,

I've observed that the "-x265-params dolby-vision-rpu /path/to/rpu" 
doesn't seem to work in my ffmpeg command. Though the libx265 
documentation indicates the presence of this parameter, ffmpeg appears 
to be having trouble recognizing it. In fact, ffmpeg reports it as an 
unknown parameter. Is this option exclusive to CLI currently? Is there 
any anticipated support for it in the future?

For reference, here's the x265 documentation: 
https://x265.readthedocs.io/en/master/cli.html

-- 
Kind regards,

Robin van der Linden

1. Wrong list.
2. That's not how x265-params is supposed to be set:
"set the x265 configuration using a :-separated list of key=value
parameters"

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:
