Plex displays wrong colours with Dolby Vision on AppleTV 4k

From a week ago, yes…
Just an update to how HDR Stream Data is displayed.

Cool - so if this is just an update to how the metadata is displayed in the media info, is Plex Player on Apple TV still discarding the MEL RPU info during playback?

I’m expecting Plex support will eventually mirror Infuse support which mirrors ATV hardware + tvOS software support:

  • no chances for dvhe.07 FEL — fallback to HDR10
  • no chances for dvhe.07 MEL — fallback to HDR10
  • dvhe.08 P8.1 (HDR10 EOTF/PQ) — may be supported sooner or later, may fall back to HDR10
  • dvhe.08 P8.4 (HLG EOTF/PQ) — sooner or later
  • dvhe.05 — sooner or later, should be supported now, but they aren’t (Infuse player is supporting them quite smoothly)

Hey @Ridley,

any chance for a quick update please?

Guess not :slight_smile:

Who would have thought that a year later it still would not be fixed. They should just tell us they admit defeat and we can all move on to Infuse instead of hanging on tenterhooks for a fix.

I wish I could “move on” to infuse, but it just isn’t fleshed out enough for me. So I’m stuck bouncing in between.

yeah infuse is not a wife friendly UX compared to plex

Is there still no fix for playing DV Profile 5 with Plex? I can’t get MKV files using DV profile 5 to play on Windows 10 via chrome, iPad, iPhone or AppleTV. I receive error “File is unplayble. Color Space is not supported”.

More and more content is being released in Dolby Vision Profile 5, and this long known bug lives on with no plan or status. This is definitely a problem with the Plex Server irrespective of the target device (web browser, Apple TV, etc.).

@Ridley - Any status?

Users having issues with HDR content in non-cross-compatible proprietary formats on devices with platform-provided support for that content should verify that there is no other reason that a transcode would be required for the file in question (bandwidth settings, etc); if not, please post client (e.g. iOS, tvOS) and server logs to facilitate further investigation.

For devices without platform-provided support for the content in question, we’re unfortunately not able to provide the features you’re requesting due to intellectual-property licensing constraints. We’d be entirely able to decode, display, and convert this content at a technical level (the technology involved is fairly simple), but we can’t build capabilities into our apps when patents on those capabilities may be held by highly-litigious third parties.

If you’d like us to be able to provide support for these formats, I’d recommend contacting the format vendor and requesting that they make their essential patents available in ways that are compatible with consumer software and open-source tools. Barring that, you can contact your local elected officials and demand legislative change to prevent individual companies from enforcing complete monopolies over technologies that are essential to perform basic tasks such as merely playing back media files. Until one of those two things change, our hands will remain tied. Thank you for your understanding.

Are we back to step 1 now?

No, worse. they’re saying it’s not their problem. They’re implying Infuse is being legally reckless by adding more DV support to their media player.

Can’t believe it took them over a year to impart that little nugget of information. At least now I know not to bother persevering with Plex. End of the road for me with it - Infuse it is.

One other thing - they keep saying converting the media would be potentially litigious… the media can be direct played so no idea what they are going on about now.

you’re right, I got it backwards.

This is insanity. The Plex app on certain platforms already plays these files! It works fine on my x900h TV but not on Apple TvOS. So that logic doesn’t fly here.

Sounds like a cheap cop out to ignore the problem.

@Ridley I am unsure what to make of this, a sample file and server logs were provided, the problem was acknowledged, the platform supports the profile.
Should it work now? Was the work abandoned?
