Plex displays wrong colours with Dolby Vision on AppleTV 4k

To be clear: is this referring to content that plays normally on the same displays using other apps or devices, or content that doesn’t play with anything else at all? Are you seeing this warped output only when transcoding, or also when Direct Streaming/Direct Playing?

I’m as happy for your engagement in this thread as I am disappointed because it it seems a basic understanding of this issue still has yet to be reached

  • transcoding still yields magenta and green tints
  • the same media can be played properly on other clients and apps using the same display. The LG Plex app plays video with this issue just fine, as well as Infuse.

This is strictly an issue with the Plex app on Apple TV

Okay, support for Direct Play and Direct Streaming of non-backwards-compatible Dolby Vision files in the Apple TV app has been discussed above:

Again, I can’t give exact timelines on feature requests, but this support will be included in upcoming releases of Plex Media Server and Plex for iOS and tvOS.

It’s not clear if we’ll be able to provide support for transcoding Dolby Vision content to other formats. The reason you see incorrect colors in Dolby Vision content is that it’s encoded in a nonstandard proprietary Dolby colorspace; it’s not clear if we can legally distribute our own implementation (whereas we can use the one built into the Apple TV). We’ll implement support if (and only if) we learn that we can do so without exposing ourselves and our users to legal action.

I appreciate your engagement here and I understand that this is not your personal policy but it is set by your employer.

But reading through this thread, I think you got a sense how deeply deeply frustrating that policy is to your customers, to a point where the attitude toward your company shifts into negativity.

We are not asking for an exact date. A “this year” or “early next year” would be enough.

Is there any chance you could bring that up somewhere somehow in a meeting and maybe think about rethinking this whole secrecy thing.

Anyhow, thanks for your work and have a nice weekend.

To be clear, this isn’t about secrecy; it’s about uncertainty. We don’t want to promise to have a new feature out by a particular date when we know that it’s possible that the release could slip due to a variety of factors, such as a major bug being discovered late in the release process. Setting expectations that we can’t be positive we’ll deliver on can lead to worse customer impressions than not saying anything about scheduling, which is why companies usually don’t. With the holiday season approaching, release cadences can also become more unpredictable as people take time off to spend with their families, so there’s more uncertainty about when a given change will ship (including whether it’s before or after the new year).

The feature work to support non-backwards-compatible Dolby Vision on Apple TV and iOS will be available in upcoming releases of those clients and the media server, which I expect to be available within the coming weeks, but I hope you can understand why I’m not able (at a practical level, rather than just a policy one) to provide any more specific a guarantee than that.

Thank you, that is specific enough for me. Appreciated.

Acknowledged with thanks. That’s progress.

Thank you for an earnest update!

Maybe an early Christmas present? Excellent news! :slight_smile:

@Ridley thank you for the update! Any word on DV .mp4 playback on the shield? Currently it does not playback on shield and it is supposed to.

In my experience, it’s best to mark DV releases as undesirable for aquisition.
That should ensure you download HDR10 ones.

DV should be fine for most nonstreaming movie releases since they are backward compatible but series are mostly not.

that’s only because plex doesn’t play them properly, and why this thread exists.

Luckily release groups have caught on quick and now label them either mp4 or mkv. So I use sonarr to grab the right one automagically.

But it’s a plex issue, that plex can eventually fix.

Actually this brings up a good point.

@Ridley do you know if DV support is planned for .mp4 and .mkv like Infuse? If the solution is to resort to using the built-in apple player then I would assume only .mp4 support would be present because AFAIK apple doesn’t support .mkv files. If the new player will support DV then I would assume both container formats would be supported, correct?

With the upcoming server support, we’ll be able to Direct Stream Dolby Vision MKV and MPEGTS files for AVPlayer.

so it’ll be like on-the-fly remuxing to mp4?

I’ll rather avoid the issue than wait around for months for the fix.

Now, this is the kind of response I can get behind.

I know this doesnt help Apple TV users per see…but Ive never been able to play DV material on my 65 inch SonyXH9505…always had the green/purple tint…but happened to play a file on my 49 inch version today and that played fine…before I even realised it was a DV version…so checked both app versions and 65 inch had an older version of the plex player…uninstalled and reinstalled and no more green tint…so on version 28703, all is good…not sure if this helps Apple users but thought Id mention all the same…will check on my ATV4Ks shortly but they get less and less use nowadays

Update…just done uninstall and reinstall on ATV4K and made no difference…shame

Just updated Shield Pro app as well and still not playing back DV on that either (without green tint) NOt sure how I got so lucky with my Sony TVs but glad I did…hope Apple TVs are stored soon for others that rely on them

Ironically most TV platforms do not have this issue but the two most expensive set top boxes do.
