Hi Guys,

I'm having a problem finding MT2S files with a TrueHD audio track in the Serviio library.

Serviio finds the files and successfully adds them to the Serviio library (no errors in the log). I'm able to find them in the library in the Serviio MediaBrower (Pro feature) to confirm this. I not however able to see them on any of my DLNA devices (generic profile). They are just not listed.

Some of my findings are:

The same video and audio tracks remuxed into a MKV container appear properly.
Files with a DTS-HD MA audio track in a MT2S container appear properly.
Only TrueHD audio tracks seem to be affected.

Example file information:

I should note that the TrueHD audio track contains both a TrueHD stream plus a 640kbit/s AC3 core.

Not too sure if I have uncovered a bug or I'm just missing something obvious.

That's because truehd audio is not supported by dlna (or last time i checked), and the generic profile doesn't transcode. So the files are missing. MediaBrowser profile transcodes the audio track and is therefore supported.

I was not aware of DLNA not supporting TrueHD audio. I've seen other DLNA servers which support it. A lightweight one that I like to use that supports TrueHD is oShare.

I'll believe you if you say that TrueHD is not supported in DLNA but the only thing that bothers me is that the same file remuxed into a MKV container works. I would expect it to also be missing as with any other different type of container. An MKV file with a TrueHD audio is shown in the library and streams correctly (I just tried this again to be sure).

I was pretty certain that it was a bug and added it to bitbucket. You can remove if you don't see it as something to be fixed (Issue #748 M2TS files with a TrueHD track are not shown in DLNA clients libraries).

Zip, I have a number of BD rips containing TrueHD, and they stream fine. Is that because my player can play the native stream without any transcoding? I have them both in MKV and M2TS containers. I've even seen DTS Master Audio show up on my receiver display, so they seem to stream as well.

Players might support truehd, but there is no DLNA (afaik) media format profile for m2ts with truehd. The fact is streams in a mkv file is, because mkv itself was not a dlna supported format until recently, so Serviio cheats and just send it anyway, with a made up profile - players generally acct it and if they support truehd audio, will play the file.

I will look at the ticket and see if truehd is now officially supported by dlna, and if not, i might add a fake profile for it as well.

That would be awesome if you could.

Hello!
I discovered the same issue: I'm not able to find *m2ts file if it contains True HD audio track: could you please fix this issue in your next patches/versions? It would be very great! There are a lot of movies in my media library contains such audio tracks.

thx in advance!

I have a workaround !!!

The issue is when TrueHD is the the default audio track. If you use tsmuxer and simply change the ordering of the audio tracks and bump TrueHD off the default spot, then Serviio will recognize the file and publish it to your player.
