DVD audio (stream) selection too limited

Recommended Posts

daffy

Hola,

 

I finally am trying to use DVBViewer as a Media Center "application" - so expect some more defect reports in that area like:

 

The DVD audio (stream) selection that is offered for multi-language DVDs is too limited.

 

I have this wonderful DVD "Ein Schweinchen namens Babe" here, with dubbing in the following languages:

 

* Englisch

* Französisch

* Deutsch

* Schwyzerdütsch

* Österreichisch

 

(it's a special, somewhat obscure edition) Well, so DVBViewer only displays

 

* Englisch

* Französisch

* Deutsch

 

in its list of audio tracks - which is a pity, considering that the "Österreichisch" version is ever so slightly ROTFL than the more heart-breaking plain "Deutsch" version :)

 

Now, I do realize that all of the three German variants are showing up as "de" audio channels, and that, for instance, Windows MediaPlayer shows me three times the entry "Deutsch" but - hey - at least it gives me the option to poke around, something that DVBViewer does not allow.

 

Request: Please, do show all three "Deutsch" tracks. :-)

 

**********

 

Below is edited output from IfoEdit - just to prove that the tracks are there...

I know that movie :)

 

The issue may be caused by avoiding double entries for a certain language (same LCID reported by the DVD navigator).

 

DVBViewer GE does it, since I have a Harry Potter DVD with three English audio tracks reported by the DVD navigator, though the DVD menu only displays one. I couldn't determine any difference between them, so I decided to drop double entries in general.

 

DVBViewer Pro does it in the same way, I suppose, thus missing the two additional German tracks.

 

However, "Schweinchen Babe" sheds a new light on it, so I'll probably change it.

I checked it. In the OSD Code there is no limiting in one LCID. In fact the code asks the idvdinfo2 for all available languages and adds them into the selection menu.

 

      for i := 0 to DVD_GetAudioCount - 1 do
       dlg.Addlabel(DVD_GetAudioLanguage(i), i, false);
     i := DVD_GetAudioCurrent;

So I'm quite sure if it is not shown in the OSD Part, it's a limitation of the IDVDInfo2 means DVDNavigator Interface.

Try the Austrian version. Then come back. It's an entirely different movie :-) I am still looking for the DVD of "Schweinchen Babe in der großen Stadt" - in Austrian, of course!

Try running IfoEdit on the DVD - it might show differences in audio stream encoding? In that case, it might be helpful for the menu to show the encoding?

Well, not in the OSD code. But have a look at URDVD (or UVideo?), where the audio tracks are retrieved. I've seen the "no duplicates" code in the DVBViewer Pro source some time ago, so I guess it's still there.

@Griga

of course I use my own code for this means directly asking the IDVDInfo2 interface of the renderer. :)

Maybe there is no LCID for Schwyzerdütsch?

 

Looking at the IfoEdit output and at what Windows MediaPlayer shows, I suspect that the tracks really are flagged as "DE" - without any indication whatsoever of the swiss-ness or austria-ness.

Daffy how exactly did you choose the dvd language in the Pro? via Menu or OSD-Blue -> audiomenu?

Via the menu: Settings -> Audio

 

Unfortunately I do not know how to accomplish this from the OSD - and I don't know whether my OSD menus are still configured appropriately to actually allow me to do anything ;-)

Well the Menu thingy does kick "double" entries. The OSD stuff not.

 

It's a PITA to test the stuff, cause the decoders are complaining about an active debugger, so I have to use some obscure decoders to get where I want. :)

Ha! :)

 

so I have to use some obscure decoders

 

This one is ok for this purpose. Needs video format detection ticked because it doesn't like resolution changes without being reconnected.

Ha! 

I changed the whole section, now it shows all languages and it adds a (ac3) where needed :).

Done. There is an additional English 2ch audio track. But the DVD navigator doesn't allow to select it while playing the DVD. IDVDControl.SelectAudioStream failes. Maybe the graph has to be stopped and reconnected for an audio format change? Well, I'll look after it if someone complains about it... :)

 

Furthermore, there is a second German subtitle track. It can be selected, but I can see no difference between the first and the second.

 

However, DVBViewer GE will show all tracks in the coming 1.8.4 release.

How about looking for the dvb_component_descriptors for the audio tracks? I know, that it's more a question for the Pro cos the GE doesn't support CI yet ;)

 

 

 

the 2nd audio track is in englisch :)

 

50 -> component_descriptor
10 -> 16 bytes
0F -> reserved for future use
01 -> stream_content +
03 -> component_type -> video, 16:9 aspect ratio without pan vectors, 25 Hz
02 -> component_tag
444555 -> ISO 639 language code: DEU
Bildformat
50 -> component_descriptor
0D -> 13 bytes
0F -> reserved for future use
02 -> stream_content +
03 -> component_type -> audio, stereo (2 channel)
03 -> component_tag
444555 -> ISO 639 language code: DEU

50 -> component_descriptor
0E -> 14 bytes
0F -> reserved for future use

Well first DVB<>DVD ;)

 

The described problem seems to be an error of premiere.

Premiere yes, but error no ;) It's about component descriptors.. (without reception we know a lot about P's HDTV in DVB-S2 thanks to the EIT and the descriptors ;) )

Don't understand what your problem is. premiere doesn't mark the english track als english but deu, so it's not a problem of the viewer. Or do you think the viewer takes the pmt, disassembles it and put fake descriptors in it? the pmt PID is just another callback with ts packages and is saved like it's delivered from the driver.

..that depends on what you want. If you want to introduce a preferred language in the DVBViewer, you have to read the component descriptors ( -> ets300468)

Well I think we stop this diskussion now, cause here is only about DVD and the different audiostreams. (absolutly descriptors free ;))

 

The DVB audio stuff is another construction site ;)

 

But your're right and we will talk about it in another thread, if the time comes to put this together ;)
