bamaster 0 Posted July 19, 2018 Share Posted July 19, 2018 (edited) Hello all, I'm pretty new to Emby but I've been running Plex on a Windows PC for several years. I've been impressed with Emby's transcoding so I switched recently. Alas, I an into an issue with HDR with one video. I don't have a lot of UHD content, but I'm not able to watch A Quiet Place with HDR. Using Plex it looks great. But Emby shows a little washed out. Here are some photos. A Quiet Place My TV is the LG OLED 55B7V. Interestingly, the "HDR" logo pops up on the TV set indicating that it's receiving an HDR signal, but the movie isn't displaying it. So I thought Emby wasn't configured for HDR properly, however Planet Earth looks perfect in both Emby and Plex.

Guest asrequested Posted July 19, 2018 Share Posted July 19, 2018 Did a quiet place, transcode? What Android TV device are you using? Link to comment Share on other sites More sharing options...
ebr 14925 Posted July 19, 2018 Share Posted July 19, 2018 Says it is direct playing. We've seen a couple of reports of this with no clue yet as to why it would work for some and not others. I'm wondering if it might have to do with the display mode selection. Is Planet Earth also at 23.976? What happens if you manually change the display mode to one of the other refresh rates?

bamaster 0 Posted July 19, 2018 Author Share Posted July 19, 2018 Did a quiet place, transcode? What Android TV device are you using? I don't think it transcoded. Looking at the Stats for Nerds in the screenshot above it shows "Play method: Direct". It's playing from the Emby app on a NVidia Shield TV 2017. Would the 7.1 TRUEHD audio cause issue? Or different aspect ratios? Link to comment Share on other sites More sharing options...

Planet Earth is playing at 59.94. When I change it to anything else, the colors are washed out. Funny, even when switching back to 59.94 the colors are washed out. I have to back out of the movie completely and restart it to get to load HDR. I tried a few framerates with A Quiet Place but nothing. Wild guess, but I think the right framerate needs to be set when loading up the video. I even switched the defaul audio track to 5.1 DD, no luck.

So, if you disable our auto framerate switching and set your Shield to the framerate that works with PE, does that one also get HDR properly?

bamaster 0 Posted July 19, 2018 Author Share Posted July 19, 2018 Another piece to the puzzle. For grins I installed the Emby app from the LG store directly on the TV. It's not my preferred solution because the 4K file is too big to stream smoothly over wifi (yes, I can hardwire into the TV, but that's not what I want to do)... BUT it looks great! I can't see the framerate in this app, though. Check it... Link to comment Share on other sites More sharing options...
bamaster 0 Posted July 19, 2018 Author Share Posted July 19, 2018 So, if you disable our auto framerate switching and set your Shield to the framerate that works with PE, does that one also get HDR properly? I disabled the framerate switching. The Shield's native framerate for this set is 59.94. PE works fine as before. AQP no workee. I changed the Shield's framerate to 23.976. PE still works fine. AQP no workee. Link to comment Share on other sites More sharing options...
ebr 14925 Posted July 19, 2018 Share Posted July 19, 2018 Okay, so it isn't related to our mode switching and both files are direct playing. That leaves me completely stumped... Link to comment Share on other sites More sharing options...
Guest asrequested Posted July 19, 2018 Share Posted July 19, 2018 I'm thinking it has to do with decoding. Possibly container splitting. I wonder what happens without hwa, or a different decoder. Link to comment Share on other sites More sharing options...
bamaster 0 Posted July 19, 2018 Author Share Posted July 19, 2018 To really mess with your head... the TV thinks it's getting an HDR signal. LG gives this icon with HDR content. But the colors are washed out. It displays this icon in the LG app, too. But HDR works through that. Link to comment Share on other sites More sharing options...
Guest asrequested Posted July 19, 2018 Share Posted July 19, 2018 So that means it's actually signalling the display it's HDR, but something is happening to the metadata, either in transport or at the decoder/splitter level. Try using an external player that will play HDR content. Not mpv, that won't do that. Maybe MX? The file is PAL, correct? Link to comment Share on other sites More sharing options...

Guest asrequested Posted July 19, 2018 Share Posted July 19, 2018 I also have an issue with the decoder and some 4k HDR movies on the shield. It's presenting differently, (I've reported it to Nvidia) but I'm wondering if it's related. Mine will play correctly, with every other decoder.

bamaster 0 Posted July 20, 2018 Author Share Posted July 20, 2018 Thank you both, Doofus and EBR. I'm not sure what the benefit/penalty is with using an external player is, but it seems to work. I'm happy with the Shield, especially with its transcoding voodoo. The Emby app only has one hiccup with only one file, hardly a problem. The problem is that paying for premier just to use the external player to solve this one problem isn't worth it. Emby is a compelling product. For now I'll keep it along with Plex.

Handl3vogn 6 Posted July 31, 2018 Share Posted July 31, 2018 (edited) Looks like we have similar issues. Like @@xenu pointed out in the other tread looks like we have problems with hdr and 3840x1600 resolution. Everything works fine when playing media from Kodi. It only happens in the emby for Android TV app Link to other thread https://emby.media/community/index.php?/topic/60362-shield-atv-hdr/ Edited July 31, 2018 by Handl3vogn Link to comment Share on other sites More sharing options...

pclausen 41 Posted August 5, 2018 Share Posted August 5, 2018 I have a 4K TV (older 2014 84UB9800 84" model) that does NOT support HDR. I also have an Nvidia Shield and was wondering how Emby on the shield deals with HDR rips playing back on TVs that don't support HDR. Will the colors look washed out, or will they look correct (albeit without HDR of course). In other words, will the colors look the same as when playing back a non HDR title/regular 1080p BRD rip?

pclausen 41 Posted August 9, 2018 Share Posted August 9, 2018 (edited) So I picked up 5th Element which I already have on BRD and the colors looks very washed out on the 4k version (but image is much sharper). BRD version: 4K HDR version: Video info from Emby: 4K content from Netflix and Amazon plays back fine on my Shield, but I don't know if any of it is HDR to begin with. My signal path is Shield -> Denon AVR-X6200W -> LG 84UB9800 Is there a way to bring up "Info for Nerds" during playback from the Shield? I wonder if that might provide a clue as to what's going on.

Smuggnat 11 Posted August 10, 2018 Share Posted August 10, 2018 Just to add to this I am experiencing the exact issue described by op. I have a LG (uj6300) 4k HDR capable tv with the Nvidia Shield and using the Emby app to play a large number of my 4k hdr files (not all) results in the TV triggering HDR mode (the odd time it won't trigger at all) but not actually playing the file in HDR. I also tried the LG Emby app and the movies play perfectly as expected, HDR and all. Definitely seems like this started happening after the shield updated to android 8.0 in June I believe it was.

ebr 14925 Posted August 10, 2018 Share Posted August 10, 2018 Hi. There are already two other topics in here on this. At this point, it appears to be an issue with the nvidia decoders but only with some content. Link to comment Share on other sites More sharing options...
Guest asrequested Posted August 14, 2018 Share Posted August 14, 2018 All you guys experiencing this issue should be telling Nvidia about it. I've told them, but the more people that do, the higher they will raise it's priority. Link to comment Share on other sites More sharing options...
iKryten 0 Posted August 15, 2018 Share Posted August 15, 2018 What do we actually tell Nvidia though? Do we have specifics on what encoder settings trigger this problem? Do the nvidia forums have any related posts? Link to comment Share on other sites More sharing options...
