jrwalte 17 Posted December 14, 2020 Share Posted December 14, 2020 I'm having an issue with getting Atmos to work with my Denon and Shield Pro 2019 (new install with this Pro. I used a regular in the past on this setup and was working). At first Atmos wouldn't work at all for Emby, but it would for Disney + and Netflix. After fiddling around with Emby (In the end I cleared the cache and restarted) I seem to have it working most of the time. For the few movies I've tried, 'Atmos' would appear on my Denon and Emby would not show it is transcoding. However, for some Dolby Vision demo files under .m2ts format, Emby wants to keep transcoding the TrueHD due to 'unsupported format'. Is the container the issue? It's not like it is a big loss if I can't play the demo files, but since I was having issues with all Atmos, I wanted to check if this is just an issue with this file type and I won't keep having issues with my movies in the future. I submitted a log as user Primary at about 2:25am EST of me playing Captain America with Atmos working and then 'Dolby Vision Demo Disc S01E03' and it transcoding. I appreciate your help Link to comment Share on other sites More sharing options...
rbjtech 4291 Posted December 14, 2020 Share Posted December 14, 2020 (edited) How is the Shield connected to the Denon ? Is it - Shield > HDMI > Denon > HDMI > TV If yes, then you should have no issues playing any Atmos audio format - True-HD or DD+ (+ DTS-X etc) If you are connecting Shield > HDMI > TV > HDMI > Denon - then this is not the optimal way to connect as you are then relying on ARC/eARC for Audio. TS files should play without transcoding, but currently the release version of Emby (ExoPlayer) on the Shield does not support DV - this should change with the upcoming release I believe.

jrwalte 17 Posted December 14, 2020 Author Share Posted December 14, 2020 It is HDMI from Shield Pro to Denon. I've used the same cables in the past on the regular Shield and it played Atmos. I didn't have the demo files at the time, so that is the difference. I never expected DV to work and it would just be HDR10? But I was thinking Atmos should? Do you think it is the fact the file has DV, that Emby gets a playback error and starts to transcode the audio even though it doesn't need to? Is there a way to force Emby not to do that?

Luke 37133 Posted December 14, 2020 Share Posted December 14, 2020 Hi there, did you explore the stats feature in the video player to learn why it was transcoding? Link to comment Share on other sites More sharing options...

It very well could be related but knowing the exact reason given would be helpful. Are you actually going to have real media in m2ts format? I would think you most likely wouldn't and would have mkvs or mp4s instead. Link to comment Share on other sites More sharing options...

Yes it said transcoding due to audio not supported. The video was still playing direct. My library is always MKV. It's just these demo files that are m2ts. I thought the exact reason would have been provided in the log that should have been submitted? Do you need anything else? Link to comment Share on other sites More sharing options...
sooty234 266 Posted December 14, 2020 Share Posted December 14, 2020 Dos your Denon actually support TrueHD? Streaming services use DD+ with Atmos, so you can't make that comparison. Link to comment Share on other sites More sharing options...
vdatanet 1549 Posted December 14, 2020 Share Posted December 14, 2020 Denon model? Link to comment Share on other sites More sharing options...
jrwalte 17 Posted December 14, 2020 Author Share Posted December 14, 2020 Yes the Denon x4500H supports TrueHD. I did get Atmos working with my MKV movies it seems (I tested 3) which are all TrueHD and it used to work with all my movies in the past on this Denon when I was using a Shield 2019. I had just upgraded it to a Shield Pro and at first Emby would keep transcoding the audio. I know the cables and the receiver aren't the issue. It might just be these particular m2ts files for the Dolby Vision/Atmos demo. But you'd think it should work with Emby, anyway. So potentially a bug to squash as DV grows in support. I downloaded the demo sites non 4k DV versions of 1080p with Atmos, which are MKV. I suspect these will probably work and not transcode. Link to comment Share on other sites More sharing options...
Luke 37133 Posted December 15, 2020 Share Posted December 15, 2020 Can you try this on the shield and see how it compares? Thanks. Link to comment Share on other sites More sharing options...
jrwalte 17 Posted December 15, 2020 Author Share Posted December 15, 2020 (edited) So the 1080p Atmos MKV plays fine. But it stinks that I can't showcase 4K HDR and Atmos at the same time, so it would be nice to fix. However, we know 4K and HDR aren't the problem, because I can get Atmos with 4K HDR movies. The only difference is 1) the m2ts container and 2) that it has DV. I don't think I have any movie with DV. I'll give the other Emby version a try.

jrwalte 17 Posted December 15, 2020 Author Share Posted December 15, 2020 The Emby for Android download has same behavior as the Shield version.

You already said all your media is in mkv so this should be no problem. Link to comment Share on other sites More sharing options...
CBers 6773 Posted December 15, 2020 Share Posted December 15, 2020 (edited) I downloaded the Chameleon.m2ts file and it direct plays the video, triggering HDR on my TV, but for some reason remuxes the TrueHD (Armos) audio to AC3. 14:30:28.701 Stream mapping: 14:30:28.701 Stream #0:0 -> #0:0 (copy) 14:30:28.701 Stream #0:2 -> #0:1 (truehd (native) -> ac3 (native)) SFNs says "Unsupported container".

We'll look into whether we can expand the exo support for m2ts. Link to comment Share on other sites More sharing options...

jrwalte 17 Posted December 15, 2020 Author Share Posted December 15, 2020 I have tried the direct play ts option and it will still transcode TrueHD. I'll need to figure out how to mux m2ts to mkv and try that. Link to comment Share on other sites More sharing options...

ebr 14939 Posted December 15, 2020 Share Posted December 15, 2020 Unfortunately, the error rolled off in your logs. I'll have to see if I can reproduce but I suspect this is a limitation of that container in Exo. Link to comment Share on other sites More sharing options...
