hevc with main10 profile won’t direct play @jeffmd said:
devices can play 10bit files using 8bit methods
I’d check my logs to see how it occurred but they’ve wiped and don’t contain anything that old.

I noticed the color drifting.
This wasn’t an issue on the AFTV2, maybe due to the difference in hardware?

I’m also experiencing the audio dropout issues documented in other threads
Try AAC in an MP4 container, there is an undocumented limit on bitrate in MKVs, e.g. files from MakeMKV won’t directplay even if AC3 track is selected. I remux the video on blurays and encode the DTS MA audio to AAC, drop it all in a MP4 container with a single FFMPEG command and playback is flawless

There was no problem with 10-bit 4K before the software updates at the end of February.
Are you sure you were using the normal player and not an external player? The old app had that ability, the new app doesn’t.
Sure, only ever used the new app, didn’t own the device before XMAS
@jeffmd said:
ptrjay, I believe what you thought was full support was not, but rather players and devices can play 10bit files using 8bit methods
It is possible that an app will covnert the 10-bit info to 8-bit for rendering purposes. The AFTV will not do this. If it receives a 10-bit HEVC file, it will not play the video, period.

If the DTS-MA is not playing it could be the way the audio is encoded. There are 2 methods, 1 is to use DTS-HD (5.1) with an extension to add the extra 2 channels. The AFTV should be able to pass through the DTS-HD portion. If the audio is encoded as a single DTS-MA stream (no extension), these won’t play.

Just a guess, but it’s possible the AFTV was initially released with the ability to play 10-bit, then something changed. I just know that 10-bit HEVC is not supported now.
hi guys, i have the same problem with hevc playback, i tried many older version from plex app, until the version v4.20.0.522 was everythink fine but after the version v4.21.0.528 the app always transcodes my 4k hevc videos to h264, can the devs change back the changes their done to the app?

@Triplex86 so reverting firmware to v4.20.0.522 or previous restores functionality? @MovieFan.Plex my Amazon Fire software didn’t update between this working and not working, only the Plex software updated. If what @Triplex86 says is true, I’ll revert firmware until a dev notices this and can comment or make a solution.

Plugged my Fire Tv box back in last (after reverting back to my old Roku 3 for Plex duites) to check if 4k playback was fixed yet, but I’m still having exactly the same problems as before.
@MovieFan.Plex has there been any update from the Devs about this known issue? I can’t see anything in the release notes.
To be honest, I am very dissapointed that Plex can’t play back 4k content on a device that is sold with 4k in it’s name. At the minute it’s just an expensive paperweight for me.
Did reverting to 4.20.0.522 work for you? In terms of 4k HEVC files being played back via Direct Play?
Update for what? 10-bit files? If so, there has not been a change. 10-bit files are still not supported. It is a hardware limitation. Unless Amazon provides an update to support 10-bit video, the app will still have to transcode the file.

All my 4k files, all of which have bit depth of 10, play directly using Kodi on PleXBMC using my FireTV2.
I bought a more powerful server and now let the files transcode. Plex seems more focused on the Nvidia shield and Amazon Cloud support so this isn’t going anywhere. I’ll check in from time to time but I’m not holding my breath. Annoying how these files used to play without transcoding and now don’t.
Ok, so my understanding on the documentation is that the AFTVv2 will accept 10bit files, but only plays them back at 8bit. I know this because before one of the updates the AFTVv2 played the video fine. (Hevc Main 10 4k). After the update it tries to force transcoding, So i haven’t been able to use it for that particular video in a while, which is disappointing. The plex software just needs to allow it to direct play and the AFTVv2 should handle the playback of the video without issue.
I decided to add a AFTVv2 to my main 4K TV in the hope that I could play the odd 4K movie via my Plex server, but reading this and based on the fact that my first effort resulted in a transcoded playback session it would appear this is still an issue.
What are the work around options?.. converting the file, another player? etc

So how can Kodi Direct Play a 10 bit HEVC 4k file perfectly fine on the Fire TV 4K?
Go back and read the first sentence you quoted from MovieFan.Plex
However, what you just showed appears to show that it just played it as a 10 bit file which Plex can already do. What it can’t do is transcode the 10 bit file to 8 bit while tone mapping the color space. This is not happening in what you just showed either.
@cayars so what you are saying is that Kodi does the 10 to 8 bit conversion? Well, then the question is, why the official Plex for Android app doesn’t do this.
it just played it as a 10 bit file which Plex can already do
What do you mean by, “which Plex can already do”? Using the official Plex app will cause a transcode from HEVC to H264, as “video.bitDepth limitation applies: 10 > 8”.
Is it not being direct played (taken from the server without transcoding or remuxing)?
The Fire TV 4K can handle this format just fine so there should not be an issue. More or less the same with a Shield TV as well.
This is different than trying to play it back on a Roku 3 at 1080P which would require downsizing as well as tone mapping plus color space change since the device can’t handle the native format.
The FireTV direct plays, but only when using the Kodi Add-on. The normal Plex App causes a transcode.
