And can you switch off the downmix that way???

 

Yes on my tests it works. When the setting is downmix i can hear the sound. When the setting is passthrough i cannot hear the sound (i don't have amplifier).

 

It's the same behaviour like on openpli dvbmediasink, on opepli dvbmediasink you are not adding dts caps when downmix is enabled. On my patch i remove the already added caps when downmix is enabled.

 

 

Hello

 

Thanks for works around dts downix. But it's not work on my DM800se

 

And where is this setting for switching beetwen passthrough and downmix placed?

Or with the following image for dm500hd:

I'm using this on my DM8000,  pass through and downmix work just fine for DTS, however, what it doesn't do is handle the DTS 5.1 core from a DTS HD track.

 

When I used before the Newnigma solution on DMM based images this was possible.

 

Any solution ?

 

Thanks

what does it do in that case, does it playback the legacy DTS data, or doesn't it playback anything?

What the Newnigma solution does is playback the legacy DTS data from a DTS HD track as you put it which is what I meant by DTS core 5.1.

 

This solution doesn't playback, there is just silence with downmix and pass through.

strange, because the legacy data is always first, I would expect dtsdownmix to ignore the substream, and play the legacy data.

If your file has extension m2ts change it to mkv and try again.

 

If you have sample please post it to check (or you can use samples from here : http://www.demo-worl...on-trailers.php)

This works on my dm800se:

 

Monster & THX (Lossless) DTS-HD MA 5.1 1080/23.98p
 

Attached File  hd_thx_monster_and_thx_lossless.jpg   41.01KB   36 downloads

 

PS. Why we display audio/x-private1-lpcm and not something more human friendly on audio details?

 

...

eServiceMP3::audio stream=0 codec=audio/x-private1-lpcm language=und

...

Thanks, but that doesn't work either.


I'm wondering if everything I need is installed, I have

Probably you need patched gst-plugin-dreambox-dvbmediasink.

 

Wait until changes show up, images build from sources (for dm800se and dm500hd) work with no problem.

Hello,

 

 

In order to display LPCM audio instead of audio/x-private1-lpcm what we need to change?

 

We are getting this value when we are calling the getTrackInfo. The value of  m_audioStreams codec is getting value here and here.

 

Probably the gst_tag_list_get_string is not returning LPCM audio, this requires patches on GStreamer right?

 

Also the gstCheckAudioPad is returning atUnknown for audio/x-private1-lpcm? We need to add atLPCM on enum and handle it?

 

...
        else if ( gst_structure_has_name (structure, "audio/x-raw-int") )
                return atPCM;
        else if ( gst_structure_has_name (structure, "audio/x-private1-lpcm") )
                return atLPCM;
....

dts is downmixed to lpcm, and the caps info is retrieved from the audiosink, so you get lpcm

We need to add gst_tag_list_add on dtsdownmix to get "LPCM audio" on description instead of audio/x-private1-lpcm?

 

gst_tag_list_add (taglist, GST_TAG_MERGE_REPLACE, GST_TAG_AUDIO_CODEC, "LPCM audio", NULL);

In that case something like 'Downmixed DTS' might be more informative
