Can you try sideloading our standard android app on the same device and see how that compares? https://emby.media/emby-for-android.html Same result. embyserver (1).txt Link to comment Share on other sites More sharing options...
rbjtech 4266 Posted July 25, 2023 Share Posted July 25, 2023 I've been part of the threads on github reporting these issues. The key issue is HDR10PLUS and DV - simply does not work unless you strip the HDR10PLUS metadata, leaving just HDR10. HDR10 and DV (to make DV8) DOES work just fine however, but the 4K Max seems to be very strict on the format. I've found remuxing/correcting with the dovi scripts from RESET_999 does the trick, and I have 100% success rate here. This is with the standard AndroidTV/FireTV Emby client - it works just fine.

DarrenFabrice 0 Posted September 1, 2023 Share Posted September 1, 2023 Has there been an update on this? Same problem here using a Fire Stick 4k Max with Dolby Vision files. Having to use plex to playback Dolby Vision files at the moment. Link to comment Share on other sites More sharing options...

Same problem here using a Fire Stick 4k Max with Dolby Vision files. Having to use plex to playback Dolby Vision files at the moment. I'm following the thread on github to the Exo Devs - they are aware, have acknowledged the issue and are 'working on it'. A few chases last week, but no news yet. I guess Google need to work with Amazon - so we just need to 'wait'. I solved it by removing the HDR10+ metadata, leaving just HDR10. Now I have no issues with HDR10 or DV+HDR10. As I have no HDR10+ devices anyway (only HDR10 or DV) - this is no big deal for me. 1 1 Link to comment Share on other sites More sharing options...

Silentninjabob 0 Posted September 12, 2023 Share Posted September 12, 2023 (edited) This is also happening on my fire TV max stick I haven't gone through specific files like others in this thread but newer content doesn't work and older content does. As a fix if I find my way with the tactile sounds only through the menu and hit the playback correction button it works again. I haven't read up on what the button does but it fixes the black screen issue if you can find it without looking.

This is a known issue and is with Google and Amazon to resolve - I don't believe Emby can resolve this (it doesn't work on Plex or JF either). 11 hours ago, Silentninjabob said: This is also happening on my fire TV max stick I haven't gone through specific files like others in this thread but newer content doesn't work and older content does.

Playback correction just forces a transcode - this is just a workaround but at least it will playback using tonemapping - but you'll lose HDR and DV.

This is frustrating as apparently Google added HDR10+ certification back in 2021. I'm using a chromecast with Google TV and get the black screen/frozen image, but it works fine on 4 other devices. Might just be time to upgrade to a Shield I guess. Link to comment Share on other sites More sharing options...
rbjtech 4266 Posted September 25, 2023 Share Posted September 25, 2023 (edited) The Shield doesn't support HDR10 Plus at all - so it will downgrade any HDR10 Plus to HDR10. DV+HDR10+ Works fine on the Shield - it will use the DV as a preference. Unfortunately, there does not appear to be the 'perfect' streaming device, that plays all forms of HDR ... and all forms of HD Audio ...

I suspect the device is simply not telling emby it can playback av1 in hardware. @ebrFYI Link to comment Share on other sites More sharing options...

The standard app attempts to decode in software. The TV app does not do that because most TV devices will not be powerful enough for smooth playback.

Interestingly, my FireTV 4K Max using the latest Emby AndroidTV Beta App is Direct Playing AV1 just fine. Infact, in comparison to the latest Android Beta App on the same device, it looks significantly better. The standard App is very difficult to watch with micro stuttering, AndroidTV is very smooth. And yes, I have checked the Screen refresh settings in the App, it didn't appear to make any difference. edit - So AndroidTV is infact transcoding despite what it says on SFN and the Dashboard .. (see below) So is the AndroidTV App using hardware acceleration, but the Android App using software decoding ? (which may explain the above) If yes, why not use the hardware acceleration like the AndroidTV App does ?

rbjtech 4266 Posted September 28, 2023 Share Posted September 28, 2023 (edited) thanks - have tried turning off the frame rate matching in both the FireTV (needs to be ON anyway, otherwise emby doesn't frame rate match regardless of setting ..) and emby - but it still drops frames. It's the only AV1 I have - so it may be the file - so I'm going to try some others ... Edited September 28, 2023 by rbjtech Link to comment Share on other sites More sharing options...
