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

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
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"
