ChrisJ60 4 Posted June 28, 2020 Share Posted June 28, 2020 (edited) I have Emby server 4.4.3.0 running on macOS 10.15.5. As clients I have: - Apple TV 4K running latest tvOS and latest Emby app - iPad Pro 11" (2nd gen) running iOS 13.5.1 and latest Emby app - LG 4K Smart TV with latest Emby app I have a number of 4K MKV files in my library, some with HDR and some without. These files *all* play via Emby on my iPad without any transcoding whatsoever. If I play the same files on the Apple TV 4K or the LG TV via the native Emby apps there is heavy transcoding activity on my server. This does not seem right; if Emby for iOS 13.5.1can play these files without any transcoding then I would have expected Emby for tvOS on an Apple TV 4K to also be able to play them without needing transcoding, I'd also have hoped that the LG native app would also not require transcoding (but that is less of an issue for me). Anyone any ideas what is going on here? Is this really how it is meant to behave? Edited June 28, 2020 by ChrisJ60 Fix typos Link to comment Share on other sites More sharing options...
RanmaCanada 165 Posted June 28, 2020 Share Posted June 28, 2020 They both use different players for different hardware. This is a very common problem with the Apple TV POS. The devs have been working on this for 2 years, but still don't have a solution for Apple and their horrible playback compatibility. A quick search or browse through the forum would have shown you that. Link to comment Share on other sites More sharing options...
ebr 12987 Posted June 28, 2020 Share Posted June 28, 2020 Hi. Did you try enabling MPV in the Apple TV settings? Link to comment Share on other sites More sharing options...
ChrisJ60 4 Posted June 28, 2020 Author Share Posted June 28, 2020 Thanks @ebr, that seems to have done the trick! Link to comment Share on other sites More sharing options...
vdatanet 1369 Posted June 29, 2020 Share Posted June 29, 2020 Well, MPV avoids transcoding but video looks horrible and framerate and dynamic range match does not work. So, that's not a solution: Link to comment Share on other sites More sharing options...
ChrisJ60 4 Posted June 29, 2020 Author Share Posted June 29, 2020 I'm not seeing those issues using MPV. Video quality is excellent, including for 4K (HEVC) and no transcoding either. I'll keep using MPV until(if) I find an issue then I'll be back here Link to comment Share on other sites More sharing options...
vdatanet 1369 Posted June 29, 2020 Share Posted June 29, 2020 Are you playing HDR content? Link to comment Share on other sites More sharing options...
ChrisJ60 4 Posted June 29, 2020 Author Share Posted June 29, 2020 Ugh, yeah, I see what you mean. HDR is pretty poor And comparing regular (non-HDR) video with e.g. the Emby app on LG TV, the quality is also noticeably inferior. So, no good solution here for Apple TV 4K then it seems. Pretty disappointing... Let's hope for some major improvements here in upcoming releases! Link to comment Share on other sites More sharing options...
Luke 30175 Posted July 8, 2020 Share Posted July 8, 2020 We are looking into improving it. Thanks for the feedback. Link to comment Share on other sites More sharing options...
embyologist 0 Posted November 30, 2020 Share Posted November 30, 2020 I'm a long time Plex user and looking at Emby due to the BF lifetime sale. I've got a Synology 1920+ setup with Emby server. The Nvidia Shield playback is flawless and CPU on Synology is low. If I try to play on Apple TV 4K, it hits 95% and struggles. Infuse plays it via Emby Server without an issue. Similarly, Plex has no issue with the playback on TVos Is this a known issue? Is there a workaround or it's on the roadmap to be fixed. Link to comment Share on other sites More sharing options...

Enable MPV player in playback options. Remember to restart the app. 1 Link to comment Share on other sites More sharing options...
