Support for DoVi profile 5 transcoding/tonemapping with latest ffmpeg?

Well, as most of you guys may be annoyed, plex would give out “File is unplayable. DoVi (Profile 5) color space is not supported.” when playing DoVi profile 5 on some devices - especially on typical web browsers.
Due to the “evil Dolby”, we cannot solve it legally for a long time. However, since 2022, ffmpeg >5.0 has already supported Dolby transcoding officially and mpv-player-windows has already supported DV tonemapping.

So, it is now 2024, why can’t I play DoVi profile 5 on my laptop browser? Is there any technical/legal problems exist? I will be very appreciate if we can support this feature. Thanks :smiley:

DoVi 5 Profile is from streaming services such as Netflix. I don’t know all of the intricacies of it, but a quick Google search found me this Reddit thread where people talk about it. May shine some light for you.
