Hi everyone!

I'm searching for a ROS package to create a virtual webcam device streaming the content of a topic of type image. The virtual webcam should be accessed by a browser to stream content with WebRTC.

Has anyone a solution for that?

Thanks!

Please see #q203812.

The jgoppert/ros-virtual-cam mentioned in the second answer is still available.

Thanks for your reply. Do you know any alternatives?

Not without you telling us why you'd need alternatives?

Do the discussed packages not work any more? If not: why not?

Its not working in my scenario (Firefox recognises the virtual camera but fails on displaying video while chrome does not even detect the camera)

That's likely a problem with v4l2loopback, not with those packages. It's not specific to any application, it's a known limitation with known work-arounds.

See v4l2loopback device detected by Chrome, not seen by Zoom or Firefox for instance.

And it seems you already posted lucasw/image_to_v4l2loopback#5, so let's give @lucasw some time to respond.
