canvas-streaming-example's Issues

Updating license?

Have you considered updating the license of this repo to MIT? As mentioned in #3, this code offers a fastinating way to stream from the canvas to any RTMP server. While usage with Facebook Live is thoroughly documented in the readme, it would benefit the larger community to allow alternative server usage.

Canvas Streaming to HLS?

Thanks,

Video image scrambled

Hi there,

We are following the example here but after a couple of minute, we started to see this on Facebook. We can still hear the audio though.

Is there anyone knows what's this problem?

Thanks

WSS Proxy

Hello, I'm having a lot of fun with this sample

I have setup my own RTMP server for streaming to and broadcasting works fine.

However, I need this functionality on a secure https page. Of course, ws:// wont work.
I have setup Apache mod_proxy and mod_proxy_wstunnel before for a webrtc project, and that works fine. For this node project, in Apache sites-enabled I set ProxyPass and ProxyPassReverse to:
"/node http://127.0.0.1:3000" and "/node-ws ws://127.0.0.1:3000"
respectively. The canvas loads over https but when I hit the Go Live button, I get the error:

WebSocket connection to 'wss://hostname.com/rtmp/rtmp%3A%2F......' failed: Error during WebSocket handshake: Unexpected response code: 404

Anybody have suggestions how I can resolve this?

ws.upgradeReq is undefined

WS module version 3.0.0 does not have upgradeReq anymore #1099.

That is really a major breaking change.
We can add req object to on Connect to get the url.

I have raised a PR with these changes:
#5

Am i missing something?

Video stream stops when tab is in background

I use the code to stream video to my own RTMP server (not Facebook's). When the tab where the stream comes from is in background (i.e. the other tab is active), the browser (Chrome) stops sending the video to the server (but audio, which comes from an AudioContext, keeps sending). Even if i use CaptureStream from a video element, not a one, the stream also stops. Are there any workarounds for this case?
I've even disabled "Throttle expensive background timers" flag in Chrome.
