No Dialog Track

[mstubbs 0]

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

Hi, what do you mean by start/stopping?

[mstubbs 0]

Keeps pausing video then starting again, makes it unwatchable. When there's no dialog track to video is flawless

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

Okay, that item should be transcoding.  Can you post the transcode (or remux) log?

Log.txt

[ebr 16169]

Yeah, the server is simply not able to transcode that item fast enough for smooth playback.

 

What kind of hardware is it running on?

[mstubbs 0]

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

Why can't the video stream copy on this one? is it the ref frames?

[ebr 16169]

I don't know why it isn't stream copying.  It also isn't copying the audio...

[Luke 42077]

Is this the new beta app?

[ebr 16169]

Not sure.  mstubbs - what version of the app?

[mstubbs 0]

1.2.31a

[ebr 16169]

1.2.31a

 

Okay, that is the release so Luke this doesn't have the changes you were thinking.

[mstubbs 0]

I'll test the beta and see if that helps

[Luke 42077]

Make sure you're also running the latest version of Emby Server.

3.0.6300.0

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

[Luke 42077]

no matter what setting?

[mstubbs 0]

Yeah it won't downmix at all, tried all combinations

[ebr 16169]

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).

Okay, I've tried summarising everything

 

On stable:

 

Audio - Direct

• 5.1 File
  Direct Play - No dialog track
• 2.0 File
  Everything fine

Audio - Downmix

 

• 5.1 file
  Direct Play - No dialog track
• 2.0 file
  Everything Fine

Audio - Downmix (Bitstream Dolby turned off)

• 5.1 File
  Transcoding - Audio Works - Constant Stuttering and stopping
• 2.0 File
  Everything Fine

On beta:

 

Audio - Direct

• 5.1 File
  Direct Play - No dialog Track
• 2.0 File
  Transcoding - Audio Fine

Audio - Downmix

• 5.1 File
  Direct Play - No Dialog Track
• 2.0 file
• Transcoding - Audio fine

Audio - downmix (Bitstream Dolby turned off)

• 5.1 File
  Transcoding - No Dialog track - Constant Stuttering and stopping
• 2.0 File
  Direct Play but with audio sync out

[ebr 16169]

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...

So looks like i'm stuck with Kodi for now
