chenks 21 Posted November 27, 2016 Share Posted November 27, 2016 (edited) hi, just got a Sony 4K android TV, (KD43X8305CBU) and testing Emby on it. everything is OK apart from the audio sync which is out. if i adjust the audio sync when playing a movie to -200 then it is ok, however i have to keep doing that every time i play something. the movie files i have are MKV x264 with DTS audio track (just the 1 audio track). i set the Emby app to downmix to stereo (as i'm playing just on the TV with the TV speakers). so i'm not sure if the problem is a TV setting or an Emby setting. i don't have any audio sync issues with Netflix or Amazon Video (which are pre-installed on the TV). and when i used a nexus player i didn't have any audio sync issues either. example of one movie with problem Video CodecH264AVCYesProfileHighLevel41Resolution1920x808Aspect ratio2.40:1AnamorphicNoInterlacedNoFramerate23.97602Bitrate11286 kbpsBit depth8 bitPixel formatyuv420pRef frames5NAL4 Audio LanguageengCodecDCAProfileDTSLayout5.1Channels6 chBitrate1536 kbpsSample rate48000 HzBit depth24 bitDefaultYesTitleEng DTS 5.1 Default Subtitle LanguageengCodecSRTDefaultNoForcedNoExternalNoTitleEnglish regular Subtitle LanguageengCodecSRTDefaultNoForcedNoExternalNoTitleEnglish sdh Edited November 27, 2016 by chenks Link to comment Share on other sites More sharing options...
ebr 14913 Posted November 27, 2016 Share Posted November 27, 2016 So the item is not transcoding, correct? Sounds like an issue in VLC's downmixing of the DTS track. Not positive what to do about it. Are you sure it is completely consistent across all of your items? Link to comment Share on other sites More sharing options...
chenks 21 Posted November 27, 2016 Author Share Posted November 27, 2016 How do I tell if it's transcoding or not? There doesn't seem to be any on-screen info to say either way. I only have one platform, android TV. When I had my Nexus player the file played fine (although that was thru Plex) I have now replaced it with a sony android TV and now trying to use emby. This file played fine previously, now doesn't with emby. It's consistent with the few I've tried so far. Link to comment Share on other sites More sharing options...
ebr 14913 Posted November 27, 2016 Share Posted November 27, 2016 Did you try the direct audio setting? Did that result in no audio? Link to comment Share on other sites More sharing options...
chenks 21 Posted November 27, 2016 Author Share Posted November 27, 2016 Just tried that. I still get audio when set to direct and the audio is now in sync. So down mix to stereo isn't needed then it seems? Link to comment Share on other sites More sharing options...
ebr 14913 Posted November 27, 2016 Share Posted November 27, 2016 Not in your particular case . Link to comment Share on other sites More sharing options...

chenks 21 Posted December 4, 2016 Author Share Posted December 4, 2016 sadly the issue is not resolved. i'm having the same problems with a file that has a 5.1 EAC3 audio track. current app settings are Audio Output - Direct Bitstream Dolby Digital audio - YES Bitstream DTD audio - YES VideoCodecH264AVCYesProfileHighLevel41Resolution1280x720Aspect ratio16:9AnamorphicNoInterlacedNoFramerate23.97602Bitrate9143 kbpsBit depth8 bitPixel formatyuv420pRef frames9NAL4 AudioLanguageengCodecEAC3Layout5.1Channels6 chBitrate640 kbpsSample rate48000 HzDefaultYesTitleEng Dolby Digital+ 5.1 Default SubtitleLanguageengCodecSRTDefaultNoForcedNoExternalNoTitleEnglish SubtitleLanguageengCodecSRTDefaultNoForcedNoExternalNoTitleEnglish (SDH) Containermkv Link to comment Share on other sites More sharing options...
ebr 14913 Posted December 4, 2016 Share Posted December 4, 2016 And is the item transcoding or direct streaming? Link to comment Share on other sites More sharing options...
chenks 21 Posted December 4, 2016 Author Share Posted December 4, 2016 Again, how do you tell if it is or not? There is no on screen notification as far as I can see. Link to comment Share on other sites More sharing options...
ebr 14913 Posted December 4, 2016 Share Posted December 4, 2016 If you turn on the "Debug options" in the app settings it will tell you on the OSD. Or you can look at the server dashboard during playback. Also, you can observe what, if any ffmpeg logs are generated by playback. Link to comment Share on other sites More sharing options...
chenks 21 Posted December 4, 2016 Author Share Posted December 4, 2016 I assume Trans/I is what you're looking for? Link to comment Share on other sites More sharing options...
ebr 14913 Posted December 4, 2016 Share Posted December 4, 2016 Yep, thanks. That means it is transcoding which means the issue is probably either with the source or created by the transcode. Luke, is this an ffmpeg issue? Is it something that could be fixed by a different version? I guess it is also possible it is a problem with the TV itself...

chenks 21 Posted December 4, 2016 Author Share Posted December 4, 2016 Plex appears to play it OK on the same TV. And the file plays fine with vlc on laptop. The TV runs android TV 5.1.1 Link to comment Share on other sites More sharing options...
Luke 37065 Posted December 4, 2016 Share Posted December 4, 2016 I would need to see a transcoding log from the server. Thanks. Link to comment Share on other sites More sharing options...
chenks 21 Posted December 4, 2016 Author Share Posted December 4, 2016 Well it's almost 11pm here, so it won't be tonight. Unless the server saves logs from when it was played earlier this evening. Link to comment Share on other sites More sharing options...
ebr 14913 Posted December 4, 2016 Share Posted December 4, 2016 It does. There should be one from your last playback. Thx. Link to comment Share on other sites More sharing options...

chenks 21 Posted December 5, 2016 Author Share Posted December 5, 2016 is that log OK? Link to comment Share on other sites More sharing options...
Luke 37065 Posted December 6, 2016 Share Posted December 6, 2016 The logs look OK to me. Since a lot is about to change with the video player it's probably best to reevaluate with the next update to the app. Thanks. Link to comment Share on other sites More sharing options...
chenks 21 Posted December 6, 2016 Author Share Posted December 6, 2016 when will that be? Link to comment Share on other sites More sharing options...
ebr 14913 Posted December 6, 2016 Share Posted December 6, 2016 If you join the open beta it will be very soon. It would actually be interesting to see if there is any impact on that TV given it is running an older Android version. Link to comment Share on other sites More sharing options...
chenks 21 Posted December 6, 2016 Author Share Posted December 6, 2016 actually there has been a slight change in the TV. i swapped it for a different model. it's now a Sony KD43XD8305.. running android tv 6.0.1 Link to comment Share on other sites More sharing options...

It would actually be interesting to see if there is any impact on that TV given it is running an older Android version. i'm still in trial mode at the moment. I'm not gonna pay for the app until i'm sure it's gonna work for me. so joining the beta probably isn't going to do much good. Link to comment Share on other sites More sharing options...
ebr 14913 Posted December 6, 2016 Share Posted December 6, 2016 The beta will respect your trial period and allow you to see if things work better with the upcoming version. There are some good changes there. Link to comment Share on other sites More sharing options...
