Hi all..
i'm trying to add a web cam to my pionner at-e robot, i have ubuntu 10.4 server version (no x systems), i have already installed the required components of GSCAM and the compilation gives no errors or warnings
i export the environment variable
$ export GSCAM_CONFIG="v4l2src device=/dev/video1 ! video/x-raw-rgb ! ffmpegcolorspace"
then i run the node
$ rosrun gscam gscam
but i get the next error:
Gstreamer Version: GStreamer 0.10.28 no element "v4l2src"
any ideas? is it possible to run gscam on a server edition of ubuntu?
thanks a lot
Mario
You need to have the gstreamer0.10-plugins-good package installed. The v4l2src element is located in the "good" plugins http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-good-plugins/html/gst-plugins-good-plugins-v4l2src.html

Mario Garzon (Feb 22)editI also have this problem. But I am not familiar more with ubuntu and I dont understand anything from this manual http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-good-plugins/html/gst-plugins-good-plugins-v4l2src.html Can I ask you to explain it for me?
Many thanks.
The manual is just for the gstreamer0.10-plugins-good library, which is used by gscam to publish the output of the webcam over ROS, in a server edition of ubuntu that library is not included so you have to manually install it usign
sudo apt-get install gstreamer0.10-plugins-good
hope that answers your question..
Mario
