Pushing the websocket data to a server? #18

Closed nicw closed 7 years ago

nicw commented 7 years ago

Hi! The scenario I have is that I need an outgoing connection from this relay to a websockets server, which then isreceiving/relaying/etc.

Your WS example is having the relay act as a client, and users connect to it, which isn't possible in my scenario (firewalls, must be outgoing).

I'm still working through your code, do you see a way that your relay could connect to a WS server and begin sending these messages?

Thanks! Nic

See around https://github.com/OliverF/mjpeg-relay/blob/master/app/broadcaster.py#L161

I believe that by modifying the code a little you'd be able to add a custom client which simply forwards to your websocket server. Or maybe simply connect a local client which forwards to your other server, but maybe there are performances penalties for this.

I had a similar issue to you a while back so I wrote a quick script to sort of "rewire" the direction connections are made: https://github.com/OliverF/rewire/blob/master/rewire.py

Think of your scenario as wanting to plug a "socket" (not the TCP kind, the physical kind) into another "socket". Since mjpeg-relay accepts connections, and so does your websockets server, you need to "rewire" this. So spin up rewire in the following way (run this on the same machine as mjpeg-relay to avoid firewall issues):

python rewire.py -o localhost:54321 -o YOUR_SERVER:12345

That will make rewire make an outgoing connection to both mjpeg-relay and your server, and then pass data between the two. You can also make some combination of incoming/outgoing sockets with rewire. It's just a simple little script so don't expect too much in the performance department.

Hope it helps!

Hey hey, very cool! Thanks for this, I'll pull it down and play with it. I'd actually stepped back for a few days as I wasn't sure if WS was going to be a viable solution for video streaming. This is rejuvenating :)
