gscam can no longer be run
I have used gscam for a while and I'm quite happy with it. However, since a week it will no longer start. I get the known 'PAUSED' error, but I don't think any settings have changed. This is the output of running it:
$ rosrun gscam gscam

The settings of the webcam at dev/video0 are:
$ ls -l /dev/video0

Note that I have read and write permissions set for every user and am myself owner of the device.
I also tried to remove and reinstall gscam, to no avail. Does anyone know what else I can try?
Maybe try with gst-launch to see that you get an image (end with e.g. ximagesink).
