mstubbs 0 Posted August 28, 2016 Share Posted August 28, 2016 (edited) Hi, on the Fire TV Stick App i'm having some audio issues - anything that is 5.1 won't play the dialog track. I can choose 'Dpwnmix to Stereo' and untick 'Bitstream Dolby Digital audio' and this seems to fix it, but causes awful start/stopping of the video. Anyone any idea how to fix this issue? Cheers in advance I should also mention that the videos play fine when using the 'Emby for Kodi' app, although i'm trying to move away from Kodi and into the Emby app Edited August 28, 2016 by mstubbs Link to comment Share on other sites More sharing options...
Luke 37007 Posted August 28, 2016 Share Posted August 28, 2016 Hi, what do you mean by start/stopping? Link to comment Share on other sites More sharing options...
mstubbs 0 Posted August 28, 2016 Author Share Posted August 28, 2016 Keeps pausing video then starting again, makes it unwatchable. When there's no dialog track to video is flawless Link to comment Share on other sites More sharing options...
ebr 14903 Posted August 28, 2016 Share Posted August 28, 2016 What is the stick plugged into? Sounds like it doesn't support multi-channel audio so selecting downmix is the proper thing to do. What is the media info on the item that you are playing and it stutters? Sounds like maybe high-bitrate content that the little processor on the stick cannot decode fast enough so you may have to lower the bitrate to force transcoding on the server.

I have 2 sticks, both with same issue, one plugged into a 42 LED LG, the other a 24 LED. This is an example that stutters Cheers Link to comment Share on other sites More sharing options...
ebr 14903 Posted August 28, 2016 Share Posted August 28, 2016 Okay, that item should be transcoding. Can you post the transcode (or remux) log? Link to comment Share on other sites More sharing options...

ebr 14903 Posted August 28, 2016 Share Posted August 28, 2016 Yeah, the server is simply not able to transcode that item fast enough for smooth playback. What kind of hardware is it running on? Link to comment Share on other sites More sharing options...
mstubbs 0 Posted August 28, 2016 Author Share Posted August 28, 2016 just a self built machine, amd e-350D APU 1.6GHz and 4 GB Ram, Windows 10 Some other 5.1s will play fine with the downmix, e.g If its server side I guess i'll have to stick with kodi for now Link to comment Share on other sites More sharing options...
Luke 37007 Posted August 28, 2016 Share Posted August 28, 2016 Why can't the video stream copy on this one? is it the ref frames? Link to comment Share on other sites More sharing options...
ebr 14903 Posted August 28, 2016 Share Posted August 28, 2016 I don't know why it isn't stream copying. It also isn't copying the audio... Link to comment Share on other sites More sharing options...

ebr 14903 Posted August 28, 2016 Share Posted August 28, 2016 1.2.31a Okay, that is the release so Luke this doesn't have the changes you were thinking. Link to comment Share on other sites More sharing options...
mstubbs 0 Posted August 28, 2016 Author Share Posted August 28, 2016 I'll test the beta and see if that helps Link to comment Share on other sites More sharing options...
Luke 37007 Posted August 28, 2016 Share Posted August 28, 2016 Make sure you're also running the latest version of Emby Server. Link to comment Share on other sites More sharing options...

mstubbs 0 Posted August 29, 2016 Author Share Posted August 29, 2016 So tested the beta, this time everything direct plays (no matter on setting) and no dialog track at all. However if I set it to play with external player (I tested vlc) it plays perfect Link to comment Share on other sites More sharing options...
Luke 37007 Posted August 29, 2016 Share Posted August 29, 2016 no matter what setting? Link to comment Share on other sites More sharing options...
mstubbs 0 Posted August 29, 2016 Author Share Posted August 29, 2016 Yeah it won't downmix at all, tried all combinations Link to comment Share on other sites More sharing options...
ebr 14903 Posted August 29, 2016 Share Posted August 29, 2016 Can you tell us exactly what you tried and what happened? If you are trying to feed the audio direct to a device that cannot decode it, then you will get no audio, but setting the output to downmix should solve that (depending on exactly what is receiving it).

ebr 14903 Posted August 30, 2016 Share Posted August 30, 2016 Okay, if your connected equipment cannot accept a Dolby Digital stream (which, apparently, it won't) then you have to turn off the option to bitstream DD. That is why you are getting no audio on DD tracks with that option on. Now, on top of that, the Fire Stick is very underpowered so we must transcode any high-def content for it and, it appears also that, maybe your server is not powerful enough to handle the transcode...
