Samsung 6 Series Playback Issues

Will need logs to be sure (see the section in red above) but my guess is UMS is transcoding one of those videos as it thinks it is not compatible with your TV.

UMS may be using the wrong conf, or it needs to be tweaked slightly to update what is supported.
there are several possible settings to check,

Code: Select all

MaxVideoWidth
MaxVideoHeight
SupportedVideoBitDepths

as well as if H265 is defined as supported.

Do they play if using the No Transcode option from the #--TRANSCODE--# folder?

If the same thing happens when playing direct from a flash drive then it will not have anything to do with UMS and it is likely to be an issue with those videos.

I think this problem could be straying into areas I know little about and others may be of more help.

But I'll try with what I can see is what it could be.

One issue you are having with the latest version is that the database is not being used which is causing a lot of errors in the logs. Sometimes the database can become corrupt or updating from a early version can cause this. The easiest way to fix that is to fully quit UMS then delete C:\ProgramData\UMS\database and on next run it will be recreated when your media is scanned.


Looking at the logs I can see that the correct conf is being used and is up to date and matches the supported formats that you posted.
Out of the local files you have that are shown in the log, all but 1 have been identified as supported so would be streamed.
The 1 that is unsupported is "[HR] Invasion S01E01 [98501AB2].mkv" because it uses the audio codec "Opus" which is not one of the supported formats on the list.

Code: Select all

Video codec "h265" failed to match support line f:mkv             v:h264                                    a:ac3|lpcm|adpcm|aac-lc|he-aac|wma|eac3|mp3|dts          m:video/x-matroska   w:4096   h:2160   b:320000000
Audio codec "opus" failed to match support line f:mkv             v:h265|mjpeg                              a:ac3|lpcm|adpcm|aac-lc|he-aac|wma|eac3|mp3|dts|truehd   m:video/x-matroska   w:4096   h:2160   b:640000000

So UMS normally would try and transcode so it will play, but transcoding 4k takes a lot of processing power and network bandwidth so it will fail for most people.

Some devices can handle unsupported audio codecs differently, some will refuse to play, others may play with no audio and possibly your TV is trying to play but has no idea what to do with the audio data if it can half understand it so is causing it to glitch. I don't know though so is just a guess if it is doing this when playing from a flash drive too.

You could try and find a different version of that video or If you cannot get the video in another format you could use something like HandBrake to manually transcode it.
