Hi neilgl,
Thanks for the response. You're right, of course, that rpicam-focus only exists on my system. I mistakenly posted with a wrong context. It should have been rpicam-vid instead:
However, the problem is actually further back in the command line...
sudo gst-launch-1.0 videotestsrc ! videoconvert ! autovideosink
I've now connected a monitor and keyboard and when I run the command locally, the test image is displayed, but I also get some warnings and critical warnings issued.

Code:
rpicam-vid --camera 1 -t 0 --qt-preview --info-text %focus --width 640 --height 480 --codec libav --libav-format mpegts --inline -o - | gst-launch-1.0 fdsrc fd=0 ! tsdemux ! h264parse ! rtph264pay config-interval=1 pt=96 ! udpsink host=192.168.0.30 port=8554 sync=falseThrough an RDP session, I can only run the command with sudo, otherwise my RDP session gets terminated. I don't even have an idea where to start looking for the solution.Code:
gst-launch-1.0 videotestsrc ! videoconvert ! autovideosink
