Webrtc_ros client

edit

Hello,

I want to transfer images from client on robot to the server on the remote PC via webrtc. I found webrtc_ros project on github: https://github.com/RobotWebTools/webrtc_ros/tree/develop/webrtc_ros. As I understood there is only webrtc_ros_server_node that starts server. I can connect to this server via my internet browser. And I can see image topics from server. That means that client can only receives a stream. So I have two questions:

• Is there a version of webrtc_ros client that I can run on robot (not in browser) and connect to the webrtc_ros server? Code that published in the mentioned repo not enough clear for me, but as I understood this client starts automatically when I connect to the server via browser.
• Is it possible for client to publish stream to the server? Now it looks like client can only receives stream.

I would be happy to get any advise or even better code snippets that could help me.
