Facebook live streams not working

[albertogasparin]

I've found two issues while trying to view Fabecook live streams.
The first one is that rtmps streams are not being recognised as supported because the code just looks for rtmp:// (easy one to solve).

The second issue is the real one: Facebook rtmps streams are not playing. The source is correctly sent to Flash but then nothing shows up (just black screen). Have a look with this stream (available for another 3 hours.):

rtmps://edgetee.xx.fbcdn.net:443/live-md/1282731655104706?api=1&s_p=1&o=lla2&a=AfDrx0WuwBQbFnDh

The stream works with both rtmpdump and this test player.

@albertogasparin sorry for the delay. Can you provide a new live stream URL? I'll enable detailed logs to try to identify the issue.

Hi @gfronza, this page might provide you more links: https://www.facebook.com/livemap/
Let me say that I've tried to debug the problem on another player that has the same issue (VideoJS) and I've discovered 2 things:

1. CDN stream servers require FCSubscribe call as they deny direct connections
2. People behind enterprise firewalls (like me) need proxyType = 'best' otherwise the connection is prevented.

I haven't checked if your code already handles those 2 scenarios.
FYI, this is the PR I've submitted to VideoJS with the changes in order to make FBLive videos work.

@albertogasparin nice!
The original OSMF.swc library was not calling FCSubscribe, but I already changed this.
So what may be causing the issue is indeed this proxyType attribute. I'm thinking about exposing this as an option in rtmpConfig (player setup) instead of hardcoding it.

[albertogasparin]

That would be great 👍
BTW, I would make the most compatible value (best) as the default option, allowing people to set it to something else if they know what they are doing. By looking around I saw that also JWPlayer does that.

@albertogasparin I drafted a new pre-release (https://github.com/flavioribeiro/clappr-rtmp-plugin/releases/tag/0.0.15-rc1). Could you test if that works for you? I don't have easy access to an enterprise proxy to validate the solution.

I added the proxyType option, the default option is none though (since none is the default option of NetConnection too).

You can close the issue if the solution works for you.

Great! Waiting for an updated version on npm.
Cheers 👍

👍 0.0.16 is now on npm. Thanks!

Yes

How ? How to get the rtmp link for watching ? From the API, I can only get the rtmp for publishing video. I can't play video from the same rtmp url.
