x264c.Param outdated?
It seems the Param type is missing a number of fields that were added in the code update commits (i_bitdepth, i_avcintra_flavor, mastering_display, etc, etc), which makes the type incorrect and unable to apply most parameters correctly.
Do you perhaps have any tooling to update these types?
Thanks for reporting. I don't have time to check that currently, I will check this when I find the time. In the meantime PR to fix this is welcome. There is no special tolling but go tool cgo -godefs can be used for that.
This should be fixed in https://github.com/gen2brain/x264-go/commit/a0a7bbb625389d9d5aa1e1b61ff642e027eebb2b. Can you please test?
