Samsung App & Buffering Problem

[Bob1969 13]

I am using version 2.2.8 via the app store, this is to avoid being inconvenienced when using the usb instalation. My windows is not using any resources at all, my windows search is disabled, no scans are taking place, cpu temp is cool and so on.

I understand that Samsung tvs can have buffering issues too so that's something to keep in mind. I reset my tv by holding down the remote power button and restarting the tv. I also unplug the tv and modem for a few minutes too. My tv and pc are connected via 5e network cables. 

This concert movie froze multiple times today,  i have attached the log file, Leonard Cohen in London, it froze at 19.04. I scanned the video with mkvtoolnix and there were no errors. 

I played this video for 1 hour via the tv source menu and selecting the Emby server. It played just fine and it proves the app is causing me a problem here.

Does it still have the same buffering problem if you preselect the AC3 audio track before clicking Play?

Thanks for your reply. It does play fine when i select the ac3 audio track, i just played it for 1 continuous hour. I seen an old post on here where the user also had issues too with FLAC stereo transcoding. My tv supports flac stereo too. I found another video with a Flac stereo audio track and it is also being transcoded.

Do you know why the FLAC stereo is being transcoded and why it is causing my video to buffer and pause.

 

edit - it direct plays FLAC stereo to my android phone

FLAC as an audio music file is supported, but FLAC within a video container such as MKV isn't supported on any Samsung TV I'm aware of.

At the back of your user's manual, you should see a chart like in the link below.

https://developer.samsung.com/smarttv/develop/specifications/media-specifications/2021-tv-video-specifications.html

That's the matrix Emby uses in the app and can be different depending on the year, but pretty much it's been the same every year for a while.

And ya, Samsung TVs are horrendous at streaming transcoded files and buffering.  I always keep a compatible audio file within my videos if they have TrueHD or DTS.  PCM 2.0 is about the only lossless audio format you can have without transcoding.  That and PGS subtitles are bad too.

Oh, and if you want to test it out just disable transcoding on the server for your user.  Your TV should start spitting out Tizen error messages.

Many thanks for your reply. At the back of my manual in the supported video containers, it does not list FLAC as a supported codec.

The second video has now buffered and paused, why is this happening when its meant to be transcoded into another format?

[Bob1969 13]

I did try disabling audio transcoding, there was no audio thats all.

Ahh, okay.  Mine usually spits out a message something about an invalid codec or something.

[FrostByte 5489]

Oh, and also your compatible audio track is going to almost always be better than what Emby transcodes to anyhow.  I think Emby transcodes to AC3 with a max 384 kbps and 5.1 or less channels.
