I have Emby for Android TV installed on a Sony kd-65xd7505 smart TV.

On Windows 10 I have installed Emby Server 3..2.26.0

My movies are on a NAS and all devices are in the same gigabit network.

 

When I start the app on my TV and select a 4K movie, playing starts but stops after a few seconds. Then, some 6 seconds later, the movie continues to play for about 10-15 seconds and stops again.

This goes on for as long as I keep watching.

HD movies play without any issue, it looks like the app is buffering all the time although the network speed is good.

When I transfer a movie from my PC to the NAS, transferring rate is more or less 50 MB/s.

I hope anyone has a solution to correct this strange behavior.

 

Thanks in advance,

Hans

Is the video direct playing? Can you post server logs and transcode logs is there is any?

I'm not sure what you mean by "direct playing" can I change that in the app or do I have to make changes in the server?

I would post the logs if I knew where to find them, sorry for my ignorance.

You can see if a file is direct playing, direct streaming, or transcoding from your server admin dashboard while playing a video. As for submitting a log refer to:

OK, when I start the movie I see this on the dashboard

Then, when the spinner ends, I see this

When I click on info this window pops up

I've attached 2 log files that were created when I started the movie, I hope this is of use.

Thanks

It appears that the file is being transcoded from h265 to h264 which is very resource intensive and is likely more than your NAS can handle. Hopefully @Luke or @ebr can see why the file isn't direct playing as the Sony TV should support h265 videos.

 

You may wish to try increasing your in-app quality settings which the video may be exceeding causing the server to transcode.

Thanks for your answer @Jdiesel. Am I right that @Luke or @ebr are also looking into it?

 

I've looked for settings in the app itself but did not find anything else then changing the maximum bit rate....

What should I look for?

 

regards.

It is transcoding because the app is requesting only stereo audio.  Is that all the TV can handle or did you set the app Audio setting to "Mix down to stereo"?

Is the video also being touched? It appears that it is going from 40Mbps h265 to 80Mbps h264.

I've just changed that, it was set to "compatible", now it is set to "direct".

The sound is via SPDIF connected to my receiver.

The sound is OK, but the movie is still playing intermittently and I still see transcoding in the dashboard.

I'm sorry @Jdiesel, English is not my native language, what do you mean by "Is the video also being touched"?

 My apologies, that was directed towards @ebr. I was simply asking if video needs to be converted or only the audio.

OK  :D .

As far as I can see from the info window, it's only the audio..... but then again, I'm not the expert ........

Was a new ffmpeg log produced?

I have the latest.

And just for your info, I've installed Emby Theater for Windows and playback is flawless, of course I have no 4K monitor.....

Are you referring  to server-63637214171.txt or the ffmpeg?

The server-63637214171.txt contains also data from the movie I was watching on my PC and that is stereo

The last transcode log you posted still is requesting 2 channel audio.  It may be that is all your hardware setup supports.

Well, when I play a HD movie, I hear perfectly 5.1 sound and the dashboard shows "direct" playing..... so imho that could not be the problem.

I'll remove the log files and do a fresh start, hang on....

So, I deleted all log files and started first a HD movie, it played without any problems with 5.1 sound, the dashboard showed this

Thereafter I played the 4K movie and the dashboard showed "transcoding" again  :(

Attached are the log files, I really hope you can find the issue.....

Hans
