Stream image contained in rostopic

[aufheben1]

For instance, I publishes topic in message type like below

string someInformation; sensor_msg/image wantToStream;

To the best of my knowledge, web_video_server streams only for rostopic, and cannot stream the image information contained in rostopic.

Is there such functionality already in this node and I'm missing it? If not, is there any plan to update these functionality?

No, it's not possible to do this with web_video_server. The topic needs to be a sensor_msgs/Image for the web_video_server to automatically detect it and "bridge it" through HTTP.
