Hi all!
I'm developping an application to extract streams from ripped DVD. A user can select the video title and the languages he wants to extract from the ripped files. To select the correct audio streams, he can preview the selected title with VLC.
In my soft, the audio streams are displayed as:
- Stream 1 : English (stream 0xBD80)
- Stream 2 : French (stream 0xBD81)
- Stream 3 : French (stream 0xBD82)
- Stream 4 : English (stream 0xBD83)
This order is based on the stream number (0xBD8X).
But I've just realized that VLC wasn't following this logic (DVDs like Alien, BeetleJuice, Yellow...) and that could lead to a wrong user choice in my software.
So what I'd like to know is: Which rule VLC is following to display the audio languages available? Is it based on the language, its type (5-1, stereo...)?
Thanks a lot!!!!

Language display order : any idea?
I tried to guess without success how VLC displays the DVD available languages. It's not :
- by language alphabetic order (English, French, Italian...)
- by audio type (stereo, 5-1, DTS...)
- by DVD stream number (0xBD80, 0xBD81...)
So what else could it be???? Thanks for any suggestion or advice!

This is perhaps somewhat related...
I have found that VLC media player selects the wrong audio track by default on my Star Trek DVDs (Deep space 9 and Voyager DVDs, region 2).
In the DVD menu, deutsch is at the top of the list, but english is the default selection.
However if I make no choice, VLC media player will use the deutsch track.
A little anoying.

For each type of subtitling system it is different. To further confuse the issue, the author of the subtitle can choose a default. In most systems, if there is no default specified, the default will be however the system is setup.
In my opinion, it would be best not to choose a default. However, the end user must be aware of this or have the system set to their prefered language and not be unhappy when the subs also default to that language.
Unfortunately, I have found many here that would prefer subtitles show in a different language than their system. So there really is no resolve other than to set a preferred language (and fall backs if that language is not available) within the player. If you create a new system, each and every player will need to provide support and it will probably be a long time before it begins to be accepted.
You might check out the various standards for subtitling on the web.
VLC has tried to accommodate every contingency, but people still complain about subtitles on a daily basis. Most probably because they don't understand how they work.

Americans in general are arrogant. Region 1 disks are most generally released first then Region 2 and so on. Rather than completely recode the disk in mastering many disks are just cloned so the default audio is still English. Really the default can be anything, Just like subtitles.
If the producer of the film requests a change of default audio and subtitle of the mastering people for each Region then the system works.
Perhaps, you should suggest to the MPEG committee that the selection of Subtitles and Audio should be automatic based on the installed Language of the system. Changes are not set in stone yet for the Blue Ray disks and because of this manufactures are open to suggestion.

I'am not sure you understood what I was saying.
The Start Trek DVDs play with deutsch audio in VLC on my system.
This is only with VLC. If I play the DVDs using PowerDVD or MS media player or something, the audio is English.
The default audio track on the Star Trek DVDs is indeed English, as it should be. But VLC selects the deutsch audio track anyway.

Yes! But, your disk is a Region 2 disk and PowerDVD and WinDVD are American products. I have found that for Region 2 disks in PAL the default in many cases is Deutsch (I have experienced other language defaults) in VLC but when played in WinDVD the same disk is English default. At the same time any Region 1 disks I play agree and the default is English.I'am not sure you understood what I was saying.

PS: If you have PowerDVD or WinDVD installed WMP 9 or 10 will agree because it is a Direct Show player and uses the same ActiveX components that are installed with either one of these programs as would any other Direct Show player. VLC is a stand alone system that uses its own libraries to decode media files and has nothing to do with Windows Direct Show filters.
Just because it is no 1 in the list does not mean it's the default. Worse yet is they may not be sorted alphabetically.I see what you mean, but when I enter the audio track selection menu using VLC, the default selected language there is English, not Deutsch.
I'm not sure what you mean by "the default selected language there is English, not Deutsch" because earlier you said of the (Deep space 9 and Voyager DVDs, region 2). In the DVD menu, deutsch is at the top of the list, but english is the default selection." I assume you mean with PowerDVD.
But you have also said "The Start Trek DVDs play with deutsch audio in VLC on my system. This is only with VLC. If I play the DVDs using PowerDVD or MS media player or something, the audio is English" This is what I responded to.
So I'm getting confused. All I know is there is discrepancies in the system and who ever came up with the idea of Region coding should be shot to put them out of our misery!
Hey! I believe you! I'm just describing what I have experienced with various programs and what I have seen others say.
The real problem is some consistency does not appear to exist between Regions. It's kind of like not knowing who is Master and who is Slave in a two drive set up. It doesn't end up working right, depending on the player and the drive and the region coding.
Also note that there is no sort order!

Just trying to explain a bit better, you did say that you are getting confused.Hey! I believe you! I'm just describing what I have experienced with various programs and what I have seen others say.
When I just put the DVD in the drive and press play in VLC, it plays with Deutsch audio. If I enter the audio track selection menu (screenshot above), the English audio track is preselected!
I do believe you that the audio track selection system is not without flaws, but I don't really see how that could possibly apply here..
What do you refer to when you say there is no sort order? The audio tracks on the StarTrek DVD are sorted alphabetically.

In this post two things appear obvious to me.
1. The default (which is a flag) was changed without changing the menu. Probably only for Region 2 disks.
2. Yes there is a sort order if I am in China, But I'm not a Chinaman I read from left to right and not from top to bottom.
It would be interesting to verify exactly how the menu and default flags are specified on the disc. Do you know of any good IFO parsers that could extract this information from the IFO file?
2: Columns are read from top to bottom in most languages (including english).
If you read columns from the leftmost column to the rightmost column and then go on to the next line, then I would not want to be you when I read a newspaper.

Is that what you call columns, could have fooled me? Hmmm! And all this time I thought I needed to be Chinese or at least have slant eyes. Certainly not marked like a newspaper!It would be interesting to verify exactly how the menu and default flags are specified on the disc.

On the other item, 99% of the commercial disks are made using the Sonic Solutions system. Hollywood's favorite software. Perhaps they have an answer for you.
