#3944 closed enhancement (fixed)

Documentation for the libx265 wrapper is missing

Reported by: raine Owned by:

Description (last modified by Timothy Gu)

libx265 has options: preset, tune, and x265-param. They are not documented in doc/encoders.texi.

This ticket was originally about missing option to adjust --psy-rd x265 option. That is invalid because there is an undocumented way to adjust it. This ticket now acts as a reminder to add more documentation for x265. See 2.

Original bug description:
x265 supports psycho-visual options since v1.2 (--psy-rd, --psy-rdoq, also related is --rd):

ffmpeg should provide a way of passing these options to libx265.

I'm guessing there are many other missing options too.

All parameters are passed with the -x265-params AVOption, which takes a : separated list of key=value parameters.
For instance:

ffmpeg -i INPUT -c:v libx265 -x265-params psy-rd=1 OUTPUT

On second thought, i'll keep the ticket open since this is a documentation issue (Namely, there isn't any).
