[gst-devel] v4lsrc input channels

[flowolf]

Hi all,
I have a problem with v4lsrc: I'm using it on a bt878 video capture 
board which has 4 input channels. On mplayer I can select the channel 
with the input option:
mplayer tv:// -tv 
driver=v4l:width=800:height=576:device=/dev/v4l/video0:input=3:norm=PAL 
-vf pp=fd

take look at this part of mplayer's output:

Selected device: BT878 video ( *** UNKNOWN/GENER
 Capabilites: capture tuner overlay clipping scales
 Device type: 171
 Supported sizes: 48x32 => 924x576
 Inputs: 4
  0: Television: tuner audio tv camera  (tuner:1, norm:pal)
  1: Composite1: audio camera  (tuner:0, norm:pal)
  2: S-Video: audio camera  (tuner:0, norm:pal)
  3: Composite3: audio camera  (tuner:0, norm:pal)
Using input 'Composite3'

How can I do the same thing with gstreamer?
Thank you and sorry for my bad english.
