how to run ros usb_cam package and webrtc on the same video device?

asked 2018-05-07 19:47:15 -0500 gravatar image


As title, I would like to run ros usb_cam driver and webrtc on the same video device (say /dev/video0) together.

If I run usb_cam driver first, then webrtc seems to to be failed to open the video device. If I run webrtc only, it seems to be ok.

Is there any idea to run both together?

You may write your own webrtc server who do not open the device,. But subscribe the video topic from the usb_cam node.

Here is a library
