[vlc] VLC and SDI video capture card

[Fernando Pescador]

Hi list,

I found the following problem when using VLC:

I have a DeckLink audio and video capture board with SDI as data input
interface.
I connect an SDI source of data with one video and several independent
stereo audio pairs (several different languages, for example).
My data source integrates all audio channels in an SDI group.

I use VLC 0.9.x to watch the TV program using the Direct Show interface.
It works fine if my SDI data source only integrates one video channel and 
one
stereo audio pair. With this configuration I can watch the TV program
without problems.

The problem appears when I integrate two or more stereo pairs. For
example, if I integrate 3 stereo pairs VLC "thinks" that I have a
5.1 speakers system and I listen 3 stereo audio channels at the same time. I
would like to know if it is possible to select only one audio channel and
to change among the available audio channels in the SDI stream.

Thanks in advance
Fernando
