I agree, a generic ancillary side data type sounds better. It would have to
be handled the same way as mastering metadata (e.g. to allocate it you'd
need to use a separate function), since the size of the data struct can't
be part of the API if we intend to add fields later.
Patrick, if you're okay with that you should submit a patch which bases
such side data on libavutil/mastering_display_metadata.h/.c
