Svtplay has geolocation lockdown, so it's blocked from outside Sweden

It seems that the problem is that UMS doesn't recognize the audio codec. Since it's registered as "undetermined" UMS can't evaluate if your TV can play the file and it falls back to transcoding. The question is why. The parsing isn't in your log (the parsing is cached, so it has probably been done earlier). To log the parsing, disable "use database" and restart UMS in trace mode. That will make UMS slower, but force the parsing to take place while being logged.
What you could also do it paste the MediaInfo output for the file (Open it in MediaInfo, select "text" output, select all, copy and paste it here).

Thanks, that's what I wanted. I don't remember the different labels used in the different versions, so it seems you found the correct option. The parsing was logged at least:

The problem is that "mp4a-40-2" isn't recognized, and thus the
audio codec ends up being "
und". This is a bug in UMS. I don't think UMS will be able to play such files on any renderer (except when you disable transcoding, which disabled the whole logic that fails) until this is addressed.
I'm sure that a sample file would be handy for anyone wanting to look at it. Can't you find some software that allows you to cut a little clip and upload somewhere? 10 seconds should be fine..

I'm no longer a part of the UMS team, so I expect one of those that are to look into the details. That said, AAC isn't really a "
codec" in the traditional sense, you should rather think of it as a "family of codecs" (
https://en.wikipedia.org/wiki/Advanced_Audio_Coding). AAC is a complete mess of many different actual implementations, some that are common and some that are hardly supported at all - and quite a few that's somewhere in between. To make it even worse, AAC was first partially defined in the MPEG-2 standard, but then redefined and vastly expanded in the MPEG-4 standard.
It suffices to say that merely recognizing something as AAC isn't enough to know how to handle it. That said, this is still a UMS bug, it shouldn't end up being "unknown".

I tried to fix it in the
https://github.com/UniversalMediaServer ... /pull/1755 and it will be released in the next UMS version
