solidus28 11 Posted October 4, 2017 Share Posted October 4, 2017 Good day! I just picked up a couple Nvidia Shield Pros this week (attempting to move from old Win7 Media Center 1080p setups). In general, it's working fine, but I'm starting to encounter some potential bugs. Wanted to see if these were known or something that could be looked into. I'm just using whatever is available in the Play store, no beta. FYI, All of my movies are blu ray rips to MKV. Receiver is a Marantz SR7010 & TV is a Vizio M70. I sent logs over from the Shield at approximately 9:35a ET on 10/4/2017. Issue #1: I noticed when I play any of the Dark Knight Trilogy movies, the audio is showing on my AVR as plain Dolby Digital. I did try a couple other Dolby TrueHD movies (didn't realize how many are DTS MA these days!) and they seem to show up normally. I've pasted media info below for The Dark Knight. It looks right to me and I never had an issue with EMC playing these movies with TrueHD. When I check on the server, it says it is Direct Playing. Issue #2: Trying to figure out the best refresh rate. If I set the Nvidia Shield to the recommended seeting (2160p, 59.97 I believe), then try to manually change the referesh rate to the 23.98 setting while playing a movie, it seems to revert back to the core audio stream and the only way I can seem to get back to the lossless audio is to stop the playback and start again, even if I pull up the OSD and pick the "HD" audio option. I've tried various movies and that always seems to be the case, but specifically in this log, I was playing Battle Los Angeles. I've pasted that Media Info from the web below as well. Thanks in advance!

ebr 14944 Posted October 4, 2017 Share Posted October 4, 2017 1) The VC1 codec has to be transcoded so that is why it is also delivering straight DD. 2) This sounds like it may be a limitation of the device's display modes but I have this movie so can test this out and see if I can discover anything. As an aside - if you don't have any 4k content, I recommend putting the Shield in 1080 mode. I think you will probably get a crisper picture all around.

solidus28 11 Posted October 4, 2017 Author Share Posted October 4, 2017 The Shield was my attempt at going to 4k I don't have much yet, but I'm sure it will grow. For #2, it didn't seem to be picky for movies. Seemed like just about any blu ray mkv I tested had the same issue. Also tried on a Vizio M55, Yamaha RX-V667, & Shield Pro at 1080p. Still seemed to drop to the lossless audio after a refresh rate switch during playback. Link to comment Share on other sites More sharing options...
ebr 14944 Posted October 4, 2017 Share Posted October 4, 2017 When you switched refresh rates (which is really a complete change of display mode for the device) the player reported an error reading the audio track and then recovered by re-playing it by transcoding. This is why you are losing your HD audio in that situation. 10-04 09:33:57.738 1985 1985 I System.out: ***** Got error from Exo player: AudioTrack write failed: -6 10-04 09:33:57.738 1985 1985 I System.out: Playback error - Failed to load video 10-04 09:33:57.739 1985 1985 I System.out: Player error encountered - retrying I can reproduce this by switching display modes after playback has started so I guess that just throws the player for a loop with HD audio. However, if you turn on auto refresh rate switching in the app, then the display mode is changed before playback starts and it works fine. This will also get you the 1080 mode for 1080 movies which will probably look slightly better on your display. Link to comment Share on other sites More sharing options...
solidus28 11 Posted October 4, 2017 Author Share Posted October 4, 2017 Ok, I uploaded a new log around 11:28a ET Didn't mention that the reason I went down the path of leaving it at the 59hz setting and manually changing was because if I do the auto refresh change (and I also have the second fine tuning option selected), it works great! Until I pause and resume. On initial pause and resume, it looks like it's missing frames or something, just seems off. If I pause and resume again, looks great! Rinse and repeat. Every other time I pause/resume the refresh rate seems funky (even though everything is still report 24p). Not the biggest thing in the world since I know I just need to pause/resume again, but another little niggle. In that log I tried it with an episode of Kevin Can Wait and repeated it multiple times on Despicable Me 3. Link to comment Share on other sites More sharing options...
ebr 14944 Posted October 4, 2017 Share Posted October 4, 2017 Okay. For the next release of the app, this will be handled by stopping the video during the display mode change and then re-starting it. Link to comment Share on other sites More sharing options...
solidus28 11 Posted October 4, 2017 Author Share Posted October 4, 2017 Thanks, Eric. Just another note. If I uncheck the Prefer exact match (forgot the exact wording), it does not exhibit the same behavior when pausing/unpausing. But I'm guessing unchecking that options makes it detect 24 instead of 23.9xxx because if I leave it unchecked, I have a little bit of stutter every 30 seconds or so. That's similar to what I used to see in Windows 7 if I selected 24 exactly, so I'm assuming that's what it's doing. My TV info doesn't seem to show me what variant of 24p it's receiving, it always just shows 24p even if it's 23.9xxx. Not sure if there is something there than can be looked at. The auto switch would definitely be the preferred method. For the VC1 thing, is that a limitation of the Shield hardware or something that Google could end up updating in the software at some point?

ebr 14944 Posted October 4, 2017 Share Posted October 4, 2017 Our menu in the OSD will tell you exactly which refresh rate is the currently selected one. I'm not sure about VC1 but I wouldn't hold your breath. These boxes are not designed to play discs and that's the only place you're gonna see that codec.

hoppel118 37 Posted October 4, 2017 Share Posted October 4, 2017 What happens if you connect your shield via hdmi to the tv directly (without an avr in the chain)? Maybe this helps to find the issue. Which version is your nvidia shield experience? With version 6.0 some refresh rate errors got solved: https://forums.geforce.com/default/topic/1025430/shield-tv/shield-experience-upgrade-6-0-for-shield-tv/ Greetings Hoppel Link to comment Share on other sites More sharing options...

I think we've discovered the issue. It is just that the stream is interrupted while the display is changing modes and that is causing an error for the player. By stopping the playback during the display mode change, we can avoid this. 1 Link to comment Share on other sites More sharing options...

I apologize if I veer too far off topic, but if I were to build a new 4K capable PC, would Emby Theater be capable of playing things like VC1 as well as 4k/hdr media?

Luke 37151 Posted October 7, 2017 Share Posted October 7, 2017 Yes Emby Theater can do that. Link to comment Share on other sites More sharing options...
KarlDag 25 Posted October 9, 2017 Share Posted October 9, 2017 For the record, I was also going to post an issue about refresh rate switching. I played a file on emby for AndroidTV and noticed it wasn't smooth (the opening scene of Star Wars with the panning text). The plex app on the same box plays the same file much better. Also, the ShieldTV has VC1 playback ability, why does it need to be transcoded? Link to comment Share on other sites More sharing options...

I played a file on emby for AndroidTV and noticed it wasn't smooth (the opening scene of Star Wars with the panning text). The plex app on the same box plays the same file much better. This is going to be completely dependent on exactly which mode was selected (there are options to control this and you can select one manually as well). It is also possible that not switching modes provides a better experience (depending on your TV). Link to comment Share on other sites More sharing options...

ebr 14944 Posted October 18, 2017 Share Posted October 18, 2017 Please test VC1 playback with the beta version 1.4.58. Thanks. Link to comment Share on other sites More sharing options...
solidus28 11 Posted January 17, 2018 Author Share Posted January 17, 2018 Did anyone ever confirm if VC1 worked now without transcoding? I returned my Shield, but would definitely give it another shot if this was working now. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
