Hi, I need to pass a video stream from the ardrone_autonomy package's topic 'ardrone/front/image_raw' to a v4l2 (Video 4 Linux 2) virtual device dev/video0. Is there any package that could help me do this? Thanks for the help! andre_th

I believe gscam can do this. Anything gstreamer can access, gscam can publish.

Right, that is the wrong direction.

But according to umlaeute/v4l2loopback/README gstreamer can be a 'feeder' for the virtual v4l loopback device.

Thanks for the suggestion. I am trying to use Gstreamer but so far I cannot make it work. Seems that is quite complicated to create a pipeline starting from images. I posted a new question on the forum: ar-drone without camera.

Later answered in Can we publish Image topic from ROS to a virtual video device

I just tried ros-virtual-cam out on a jade/14.04 system, looked fine.

If you want to run the tests:

sudo pip install v4l2capture
