[FFmpeg-user] feature request/suggestion: add support for dolby vision decoding :)

Hi all,

I have been using FFmpeg for a while now, but I am quite new to the mailing
lists, and I accidently chose the wrong one for mailing (Trac). Sorry about
that. Anyway, one thing I noticed is the lack of a Dolby Vision decoder in

Dolby Vision is a 12-bit HDR dual layer codec that has a 10-bit base layer
of either HEVC or AVC, and then an enhancement layer that supplies an extra
2-bits and dynamic HDR metadata. The result can be played on Dolby Vision
compatible TVs.

Would it be possible to implement a decoder for Dolby Vision in libavcodec
and register it using the AVCodec struct? I think it would be nice to see
that, as I know that FFmpeg can decode HDR10, which is another HDR video
format that uses HEVC (except that it is 10-bit, not 12.). Eventually we
will see Ultra-HD Blu-ray discs with Dolby Vision encoded video, so it
would be really useful for a decoder to be implemented.

Best regards,
Andrew Sun
