[Solved] Error when trying to play movie on Samsung SmartTV UE75KS8005

I have a problem playing back mp4 movie files downloaded from svt play on my Samsung SmartTV.

When I select a movie and hit play, the TV displays a loading progress indicator for a short time and then gives me an error message.

However the TV could play the same files when I used Windows 10 media sharing, so I figured that the files are ok. I figured out a workaround for these particular files, by adding the "mp4" extension to "Skip transcoding for the following extensions", the TV can play them, but then I do want transcoding for other files; that was the reason for switching to universal media server.

I have enabled tracing and restarted, then reproduced the issue with just one movie file in my library in order to reduce the size of the logs. The logs are attached to this post.

The movie that cannot play is from https://www.svtplay.se/video/254347/tim ... ickar-boll
The tool I used to download it is https://github.com/spaam/svtplay-dl

What should I do to fix this so it properly detects whether transcoding is needed and so that transcoding actually works?

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).

I disabled the media library, hopefully that was what you meant by disabling database. I also ran MediaInfo for the file:

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..

Hi Nadahar,
I encountered the same issue with lots of my MP4 files when trying to render them on my LG SJ800V with WebOS v5.8:

Hence, there seems to be a bug in leveraging the parsing result as it was obviously identified as AAC by MediaInfo.

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

Hi valib,
thank you very much for fixing this issue! Meanwhile I have set up my renderer configuration in a way ignoring the audio codec at all since my LG TV renders all of the codecs I encountered in my video files like a charm. Still, I'm looking forward to the new release and finalize the configurations.

Best regards,
fuggi
