Save audio to MKV does not work correctly

[xerces8]

I opened a MKV movie file to save/convert.
In the Save/convert dialog I created a new profile, where I enabled only Audio (with the "keep original audio track" option enabled) and Encapsulation MKV.

But the created file was not of type MKV but MPEG (the filename has a .ps appended by VLC).

Also, if I enable "keep original audio track" , what is the meaning of the Codec, Citrate, Channels and Sample Rate options? Should they not be ghosted/disabled, as no re-encoding is being done?

PS: I use VLC 1.1.5 on WinXP Pro SP3

Add file extension by yourself. So video.mkv when you select filename.

I'm not complaining about the file name, but the file contents.

I tried vlc-1.2.0-git-20101231-0002-win32.7z and it is similar there.

If I select an output file named "abc" , VLC changes it isto "abc.ps".
Then even if I select a profile that specifies MKV output, VLC saves something else (I guess MPEG).
If manually change the filename to "abc.mkv" in the text field, before clicking "Start", then it saves MKV.

So the profile selection is effectively ignored.
That is wrong in my opinion.

VLC takes muxer firstly from file extension. And if you don't give file extension, it will default to .ps, so you have to add file extension if you want to get right muxer.

[xerces8]

So the profile setting is completely ignored?

[VLC_help]

For encapsulation yes.

[xerces8]

Then why is it there in the first place? It just confuses the user.

It was changed at some point. And nobody has bothered to update the GUI.
