Samsung QN90BA Cant stream files bigger than 50gb

[morfeas2004gr]

Hello everyone,
i have a Samsung QN90BA and i use universal media sever a lot of years.
After upgrading my internet connection to 300Mpbs i wanted to play some movies (50gb and more) but on my Tv it say that is 0bytes.
I stated to play with some renders but again the same.

I connected my Tv with 5Ghz wifi and the connection is perfect and continiously, without any problem.

Do you have any suggestion ?

Thanks!

I would need to see your logs to know what UMS is doing and to be of any help. See the link in my sig.

Internet connection speed has no effect on UMS as it only applies to your local network speed between the computer running UMS and your TV.

If it is showing 0 bytes on the TV then it means that UMS has decided that video is in a format the TV cannot play so will transcode when you play it.
As that transcoded video does not yet exist it will show as 0 bytes as there is no way of knowing the final file size.

It could be that the video is supported and can just be streamed depending on what conf file it is using for the TV.
One way to test this is to play from the #--TRANSCODE--# folder and choose "No Transcoding".
If it will not play then UMS is doing the right thing, if it does then the conf can be tweaked to add that format as supported.

If you do not see this folder then you can enable it in the settings.

Do you want me to run a file that is not playing on my tv and after that send you the log ? Also which log do you want Error, warning, Info, dubug ? Which one ?

Thanks!

Follow the instructions here and show the attempt at playing the video before packing the logs.

That video has DTSHD audio which that TV does not support so it has to be transcoded to be playable.

Code: Select all

Audio codec "dtshd" failed to match support line f:mkv    v:h265    a:ac3|lpcm|adpcm|aac-lc|aac-ltp|aac-main|aac-ssr|he-aac|wma|eac3|ac4|mp3|opus    m:video/x-matroska    w:4096   h:2160   b:800000000   si:ASS|SUBRIP|VOBSUB

Samsung stopped supporting DTS years ago to save on licencing fees.

Transcoding 4K does take a lot of processing power so it might be your computer is unable to keep up.
If you have a graphics card that can hardware encode you can enable this and let it do all the work.

Make sure the GPU is enabled and set the "AVC/H.264 GPU encoding acceleration method:" to a suitable option for your GPU.

Another option is to try a different transcoding profile.
The one used is for HLS which should give an experience similar to just streaming and allow you to enable subtitles on the fly, but requires a full transcode.

MPEGTS-H265-AC3 could be used instead and here it will remux the video and only transcode the audio.
This will have disadvantages like unable to seek (depends on the renderer) and unable to change subs or audio track unless you restart the video.
Also for anything else that is not h265 and unsupported these will be transcoded to h265 which takes even more processing.

I tweaked the conf to do this if the GPU options did not work for you and you want to try this. Save it to "C:\ProgramData\UMS\renderers" and restart UMS.

If you don't have many videos that use DTS you could find other versions of those that do not have this and avoid ones with DTS in the future.
Or you could use something like MKVtools to convert the audio into another format like AC3 so UMS can then stream it.
