Can you explain what this CONVERTER_COLOR_PROFILE option is actually doing?
You've passed the primaries and transfer function to AMF options later on, but this seems to then only consider a subset of possible matrices rather than just passing that through as well to write into the VUI metadata. Why?
(If this isn't supported by AMF then a more correct solution might be to insert a metadata BSF to edit the correct values into the output stream after it has been encoded.)

Mixed FF_/AV_PROFILE enums looks a bit odd.

Move the first setting of color_depth here? The setting above in unrelated code is easy to miss.

Is this the input bit depth or the codec bit depth? (Can they be different?)
