x265 Profile cannot be set at all

Description (last modified by cehoyos)

There does not seems to be a way to set the profile for x265.
I tried two ways:

 -profile:v main

or

-x265-params profile=main

Both does not work.

Here is the output when using -profile:v main

Using -x265-params profile=main does start encoding but the error above says the Profile option is unknown and ignored.

How can one set the profile for x265?

The same happens when using Tune and Preset.

  • Component changed from ffmpeg to avcodec
  • Description modified (diff)
  • Keywords libx265 added
  • Priority changed from normal to wish
  • Type changed from defect to enhancement

Possibly related to ticket #4284.

Not related.

x265 docs say "Note that unless an option is listed as CLI ONLY the option is also supported by x265_param_parse()." And profile is indicated as CLI ONLY.

Further, "API users must call x265_param_apply_profile()" which lavc/libx265.c never does.
