Actually /dev/video0 exist, in some cases is a tv card or in other cases is another video card. I was looking for a simple way to find out the web cam device with a bash command (or set of commands). I admit that I had no idea that gstreamer-properties affects gconf variables, so I can query gconf variables with bash commands, but I wonder if there is a (gst) command that retrieves data from gconf variables.

I'm tryng to write a simple intranet videochat script in bash, it just connects 2 pc in a lan trough ssh and using gst-launch the script opens the remote cam and shows the image on the local pc. It's quite easy using a pipe like this: gst-launch v4l2src ! videoscale ! video/x-raw-yuv,width=320,height=240, framerate=30/1 ! ffmpegcolorspace ! jpegenc ! tcpserversink host=$MyIp port=1000 (I use tcp because the router filters udp) That works, but if the remote pc has the cam on a device that is not /dev/vide0 the pipe can't shows the image of the web cam. I have to specify in the pipe    device=/dev/video1. So I tried the autovideosrc option, but no way the pipe is still showing the /dev/video0 device, even if in gstreamer-properties the video input device defined is the usb web cam. </BLOCKQUOTE> the settings done in gstreamer-properties would affect gconfvideosource /gsettingsvideosrc. One more question, is there a /dev/video0? If not v4l2src could probably be enhanced to try /dev/video1 and so on automatically. Stefan <BLOCKQUOTE TYPE=CITE> How can I do to obtain an automatic detection of the web cam device in the pipe?
