Actually, rosbridge isn’t such a good choice for this. For any remote video streaming you’ll want to use webrtc or similar, see the blog post below.
Tl;dr: rosbridge (a) sends individually compressed images rather than using 100x more efficient stream compression like h264, and (b) won’t handle network issues the right way: it will incur latency when it should dynamically reduce image quality instead and it won’t drop old frames in favor of newer ones.
