IceBoosteR 10 Posted January 6, 2019 Share Posted January 6, 2019 (edited) Hi, I have boought myself a XBOX One S, as this console is capable of DTS:X and Dolby Atmos. I have a new Denon AVR-2500H as AVR with Atmos and DTS:X capability. In the XBOX settings, I have enabled 4K and Bitstream as audio-format (I have also activated Dolby Atmos for Home Theater). I play now my test movie: Star Wars Episode VII with Atmos as aduio. I play this with the Emby app, but the server needs to transcode as video and audio codec is not supported. I am out of ideas why this is happening, I don't see a configuration issue as I have enabled HDR, 4K and bitstream everywhere. Is this an Emby bug? Currently the newest 4K movies are not watchable for me ... Logfile attached Edited January 6, 2019 by IceBoosteR 2 Link to comment Share on other sites More sharing options...
Luke 37008 Posted January 6, 2019 Share Posted January 6, 2019 Hi, if you use emby user permission to disable access to all transcoding features, do the videos play in the Xbox app, or do they fail? Link to comment Share on other sites More sharing options...
IceBoosteR 10 Posted January 6, 2019 Author Share Posted January 6, 2019 Hi @@Luke, I have diabled: Allow audio playback that requires transcoding Allow video playback that requires transcoding Allow video playback that requires conversion without re-encoding Allow media downloading and syncing that requires transcoding Allow media conversion The Movie is now playing in 4K seamless, but I have no sound. I am also unable to see the "statistics for nerds" menu. Thanks Link to comment Share on other sites More sharing options...

Ohhh f*ck. ANd I have bought myself a XBOX BECAUSE I thought it is cabable of DTS:X nad DD Atmos (which is true...), but not for Emby which is my library for everything .... Is there any possibility to get this to work? I mean I need Emby Theater to have this running on XBOX .... There are not much applications in the Microsoft Store, so the devs can maybe force M$ to do so? Edit: Created a suggestion at the XBOX user voice forum.... https://xboxideas.uservoice.com/forums/911263-idea-drive-suggestion-box/suggestions/36457156-allow-bitstream-passthru-for-3rd-party-apps Ad there is something similar: https://xboxideas.uservoice.com/forums/911263-idea-drive-suggestion-box/suggestions/35722747-idea-drive-for-xbox-media-apps-blu-ray-media-pla#comments Vote for it guys! @@The Emby dev team, if there is anything I could do to help you, lemme know Edited January 6, 2019 by IceBoosteR 1 Link to comment Share on other sites More sharing options...

MrFlibbles 21 Posted January 8, 2019 Share Posted January 8, 2019 (edited) I'm guessing to have the Emby app use "exclusive" mode on the XBox? From the post linked above: App developers absolutely CAN code their app so it goes into Exclusive mode. It's in the SDK. They just haven't yet. But the point remains that there's nothing there for Microsoft to fix. That flag to put apps into exclusive mode has been in the SDK for a while now, and is the only solution you're going to see.

I too have seen this exact statement quoted on a number of threads regarding this topic. Unfortunately, never with instructions on where or how to enable this flag with typical response from Devs being they are unable to locate this flag at all. In all fairness, I've never used their SDK, so can't definitively comment on the actual existence of this flag. I can only assume that if such a flag was available, we would see Pass-through/Bit-streaming audio working on something else besides the "Big 4" streaming apps. Add to that fact that the Kodi Devs worked directly with a Microsoft engineer to port Kodi to Windows UWP, and the fact that they (Kodi's Windows UWP Devs) claim it's currently impossible, I can only assume it's not currently possible. That said, I too am hopeful for a solution to be found for this. Pass-through/Bit-streaming audio not available on the XB1 is really the only thing stopping me from using the XB1 as my main media client. Link to comment Share on other sites More sharing options...
Luke 37008 Posted January 9, 2019 Share Posted January 9, 2019 Yea looking at the api for exclusive mode, it's not that simple. We'll have to stream the data to the audio renderer ourselves, which we currently do not do. The video player handles this for us, so more than likely, we need a new video player. And truthfully based on what i"m reading I'm not even sure it's possible at this stage. 1 Link to comment Share on other sites More sharing options...

Luke 37008 Posted January 12, 2019 Share Posted January 12, 2019 I don't think I'm in a position to answer that. The first step would be for MS to allow all apps to utilize the feature.

Devdroid 21 Posted September 27, 2020 Share Posted September 27, 2020 (edited) Any news on this with regard to Xbox Series X? Guess it's hard to answer before the consoles are available to the general public. Microsoft should send a devkit to @Luke I've pre-ordered the Series X and stumbled upon this thread while trying to figure out if could get it to output Atmos, but alas, probably not. Guess it also won't work with headphones and Dolby Atmos or Windows Sonic? Edited September 27, 2020 by Devdroid Link to comment Share on other sites More sharing options...
Luke 37008 Posted October 3, 2020 Share Posted October 3, 2020 I would think our app should just work on it but we'll see. Link to comment Share on other sites More sharing options...
Moreje 14 Posted January 30, 2021 Share Posted January 30, 2021 Hello, I have bad experience with playing 4K movies on my new Xbox series X (ethernet connected). video is sluttered, transcode playing only audio is transcoded too, whereas my receiver/TV are compatible with the codec. the same movie is well played on my Surface book connected with Wifi is there any plans to upgrade /optimize this app for the Xbox SX? Thank you Moreje 1 Link to comment Share on other sites More sharing options...
Moreje 14 Posted January 30, 2021 Share Posted January 30, 2021 well, it's not working on XBsx... no direct stream, no passthrough Link to comment Share on other sites More sharing options...
MBSki 1009 Posted January 31, 2021 Share Posted January 31, 2021 @Luke You just need to allow the audio to transcode independently of the video to get 4k to work. I've been asking for this for more than a year. I know you have a new "merged" app for Windows and Xbox, but can't you at least just add a fix to separate out the audio and video transcodes so we can watch 4k on the xbox? 2 Link to comment Share on other sites More sharing options...
Moreje 14 Posted January 31, 2021 Share Posted January 31, 2021 I use emby on my 2017 android 4k TV, and it works perfectly. For me, emby on Xbox series X is a total regression Link to comment Share on other sites More sharing options...
