DTS file support (in .dts and .wav files)

I have a Samsung UN55ES6100 and some file.dts and file.wav (containing DTS data from a CD) I would like to play.

How can I modify profiles.xml to transcode this to LPCM ... or ideally play it as a DTS stream ... fallback being encoding as AC3 with a loss in fidelity due to transcoding to lossy format.

You could comment on this ticket and even add a sample or link to it

OK, so i've explored a bit and come to the conclusion that multi-channel audio is not possible with DLNA.

The closest one can do, is convert multichannel audio into a video stream with a basic video stream and the mch audio stream.

ZIP - Before I submit a feature request - could I ask what you think of this idea? I'll send you a link to a sample mch audio file converted to video in an PM.

From what I can tell - it would be a kludge to work this into Serviio:
1) If while Serviio is scanning an folder marked as an audio source directory it comes across:
a) FLAC with more than 2 channels,
b) a /.dts$/i file
c) a /.wav$/i file which ffmpeg says contains a DTS stream
d) a /.ac3$/i file
==> Then add an entry in the library under video where the data stream is produced using:

  Code:

ffmpeg -loop_input -i "$dir/folder.jpg" -b 10 -r 1 -i "$dir/$audiofile" $AUDIOCODEC $VIDEOCODEC -shortest $OUTPUT

Where:
- $dir is the dir containing the $audiofile
- If $dir/folder.jpg does not exists, use the Serviio Logo
- $AUDIOCODEC could be something like "-acodec ac3 -ab 640k" or "-acodec dca -ab 1509k -strict experimental" ... depending on the player profile
- $VIDEOCODEC could be something like "-vcodec libx264 -b 100k -r 1" or "-vcodec xvid -b 100k -r 1" ... depending on the player profile

Script to convert MultiChannel Audio into a MultiChannel video stream that works on my Samsung TV served up by Serviio

Multichannel audio should be possible, at least for some renderers (they have DTS/AAC profiles I think). I will see first if that can be developed and if not then I'd be looking at hacks. Hold on with the request.
