"Ok, to pass all those through, change the "mpegts" container to the following:"

Hi, where is this file located and what's it called? Can you edit it with notepad?

Thanks.

Those changes are part of the 2.4.5 release (for the "Sony BDP (PAL)" device profile).

Device profiles are here: http://forum.conceiva.com/showthread...ofiles-located and yes, you can edit them with Notepad. Just remove read-only from them first.

Thanks, Dennis. I would be interested in doing this with a BD-C6900 (Samsung BDP-3D profile) and a Samsung C7000 TV.
It looks like the profile for the BDP has only the AC3 audio codec parameter in the mpegts container. The BD-C6900 can support DTS audio but not trueHD. That's all I've tried so far.

I'm not sure which profile file is for the Samsung C, but assuming the one for the BDP is "SamsungBDP-3D.prf".
But it would be nice to add the DTS pass through capability to the profile. Is that possible? TIA.

I have to say that my DLNA experience has been soooooo much better since these changes. Negligible FFmpeg CPU usage and superb video and audio qualities.

Did you try adding the "dts" codec to the BDP profile? If you did, did it play natively?

The "C" profile is in the "SamsungLA.prf" file.

Will Mezzmo pass-through "MVC (Multiview Video Codec)"? Thanks.

Thanks Dennis,

It worked to add the DTS to the profile "SamsungBDP-3D.prf" as follows:

<avcontainer id="mpegts" name="mpegts" encode="0" mimetype="video/mpeg" dlnaprofile="MP3" supportschunked="0">
<video>
<format id="h264" encode="0">
</format>
</video>
<video>
<format id="mpeg2" encode="0">
</format>
</video>
<audio>
<format id="dts" encode="0">
</format>
</audio>
<audio>
<format id="ac3" encode="0">
</format>
</audio>
</avcontainer>

The BDC6900 will pass the DTS audio without re-encoding, but if I force re-encoding (to compress the file size) with "Deliver media files supported by the device: Never Deliver" in the advanced device settings, it always re-encodes the audio from DTS to AC3 dolby.

If I play the file without transcoding, it plays with the DTS but stutters a lot.
Is it possible to re-encode the original video to a smaller file size and still keep the DTS audio? I'm hoping that playing back the transcoded file will get rid of the stuttering even if the audio is DTS.

Thanks Again.

PS I did the same thing with my Samsung C7000 TV with the same results except that the C7000 has an extra 'sound' selection under the TV's remote tools button and allows me to switch from Dolby to PCM. The BDC6900 doesn't have that feature.

Can you please post FFmpeg information on such a file?

Thanks - we'll add it to our profile to be shipped with the next update.

That's because the encoding container doesn't have encoding enabled for DTS. Can you please send a message to support mentioning this thread and I'll send you a device profile to try.

Email request sent. I look forward to trying the new profile.

Thanks very much again, Dennis!
