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@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 <div>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?
