Panasonic Viera & PS3 - DTS / transcode incompatabilities

Hi there,

First things first……Serviio is an exceptionally good media server, so kudos to all the hard work!

I need a little help / advice;

I'm a little confused with the profiles and the way Serviio is handling devices. I have two devices and they behave very differently with a fairly common file format I use. The file type is MKV, h264 video, DTS audio

My settings are to NOT transcode (reason is below)

1st (main) device is a Panasonic Viera GT50;

This device is being picked up in serviio correctly. Any of the above files play perfectly and with DTS sound which is converted by the TV out the speakers, and passed optically to my home theatre decoder as DTS via the optical link on the TV. This setup is perfect.
If I enable transcoding in Servio, the audio changes to AC3, which is a not as good, so I never have this option enabled.

My 2nd device is a PS3;

Again, the device is being picked up by Servio correctly, however all the files are shown as unsupported. I have tried a few options, one is to enable transcoding (which in turn kills DTS on the Panasonic), and mess about with the PS3 profile. Some of the files then show up as supported.

Reading other posts, I see that serving DTS in stream is not something Servio (or rather ffmpeg) can do, and that TsMuxer (PS3 media server) can.

What I don’t understand is that with transcoding off , how is serviio streaming the raw h264/dts tracks out to the Panasonic, and if it can, how come I can’t get it to work on the PS3 (I have tried a dirty fix of choosing the Panasonic profile for the PS3, but this didn’t work….)

I’m desperate to dump PS3 media server if I can get this to work, anyone got any tips?

PS3 doesn't support DTS, AFAIK. The Pana might, and if it plays with transcoding off, you just need to remove dts transcoding form the profile and then you're good to keep transcoding on.

In PS3 Media Server there is several options to play DTS via PS3, it seems it embed DTS in an LPCM stream.

EDIT : Here is the option name in the profile :
  Code:
# WrapDTSIntoPCM: Set to "true" if the media renderer supports DTS wrapped
# into LPCM in a MPEG file.
WrapDTSIntoPCM = true

That is not supported by Serviio

I know, that's my point, maybe it should be implemented if FFmpeg can do this.

I was looking at it and don't think FFmpeg can do it.
