[vlc] Re: Questions about VLC using two channels at the same time

[Juliano Pillati]

I use here capture video(bt878) and ido streaming all simultaneouly 
without problem..  sucess in v4l and v4l2 too.
I use one simple command line for so streaming.. using in each card 
/dev/video0 video1 video2 and video3. That are separated devices..  Vlc 
not have problem for me doing that...
