Selecting Video Input

[Ian Davidson]

I have a Video Capture card which I know works.  I can run xawtv and can 
see the video from my camera connected to the Composite input. Xawtv 
allows me to save the configuration information and that is below.


[ian at localhost ~]$ cat .xawtv
[global]
ratio = 4:3
freqtab = europe-west
pixsize = 128 x 96
pixcols = 1
jpeg-quality = 75
keypad-ntsc = no
keypad-partial = yes
osd = yes
osd-position = 30 , 20
use-wm-fullscreen = yes

# [Station name]
# capture = overlay | grabdisplay | on | off
# input = Television | Composite1 | S-Video | ...
# norm = PAL | NTSC | SECAM | ...
# channel = #
# fine = # (-128..+127)
# key = keysym | modifier+keysym
# color = #
# bright = #
# hue = #
# contrast = #

[defaults]
group = main
norm = PAL
input = Composite1
capture = grab

When I try to use GStreamer using the following command, I do not get 
the video input captured
gst-launch-1.0 v4l2src ! 
'video/x-raw,format=(string)I420,width=320,height=240,framerate=(fraction)25/1' 
! queue ! mux. alsasrc num-buffers=440 ! audioconvert ! 
'audio/x-raw,rate=44100,channels=2' ! queue ! mux. avimux name=mux ! 
filesink location=test.avi

I suspect that GStreamer is not defaulting to the Composite1 source, but 
some other - so how do I convince it to use the Composite1?

Thanks
