Inconsistent Colour Reproduction in Swiftin and Jellyfin Mobile iOS Clients

[milesmorales]

Enable tone mapping.  Currently, Jellyfin will always convert HDR to SDR when transcoding HDR video.  Without tone mapping this will result in washed out colors.  Tone mapping will gracefully convert the color spaces.  You lose HDR but maintain accurate colors.

If it is sometimes direct playing and sometimes not, make sure that you've set the "maximum bit rate" to the highest manual value instead of auto.  Sometimes the auto detection will return an incorrect and low value, resulting in unnecessary transcoding.

There is on going work to allow for HDR to HDR transcoding.  But no ETA.

Thanks for the input, what I understood so far is that if it is Direct play it isn't transcoding anything? (Only decoding but no encoding), but in the case of Washed out colours it is decoding and encoding as per the task manager info on my GPU.

So there is no way to view HDR or Dolby Vision content using Jellyfin on any client?
