Janus Gateway only work with Web RTC ? Can it be configure to work with flash audio video?

[Justin Patel]

Hello,

As we are planning to use Janus for webinar, we may have few client which do not use web rtc enabled browser, in that case can Janus be integrated with flash audio and video ?

[Lorenzo Miniero]

Not at the moment, if you want support for Flash you'll need to integrate this yourself. We have plans to start working on this but not in the near future. A more or less simple approach that doesn't need much coding could be to redirect the incoming video from publishers in the videoroom plugin to an external ffmpeg/gstreamer pipeline that translates the RTP to RTMP/codecs a flash media server expects.

Do you think this can be done by just simple writing plugin for janus? or we have to have new server for this ?

[Lorenzo Miniero]

You probably don't need a new plugin for that, you can just extend the videoroom one with the feature you want.

Thank you for fast reply.

I have small question..

If we write java applate plugin for desktop share, can this be transfer with data channel ? and record it ?

At the moment the data channels support in Janus is limited to strings, no generic data.

can this be change? or extended ?

Further work on data channels is planned not sure when this will happen though.

Why would you want ugly old Flash? It is so yesteryear, and doesn't work on many mobile devices.

If you want Webrtc support for Internet Explorer or Safari browsers use the Temasys plugin.  If you use their adapter.js file in your project it will prompt to install the plugin where needed.

If you want Webrtc support for ios devices, your site visitors can use Bowser from the Apple Store.

Did anyone used Temasys plugin with Janus gateway? It works?

[Lorenzo Miniero]

I didn't test it personally, but I know of people who used it successfully. In general, I don't see why it shouldn't, as Janus can talk to whatever uses WebRTC. You may need to edit janus.js (if you're not the WebRTC part yourself) to use a different adapter, though.

I replaced it with Tamesys adapter.js: https://github.com/Temasys/AdapterJS

But it doesn't work, for example Echo test demo fails receiving the stream on the event 'onlocalstream'. (Attach screenshoots)

Any idea?

Thanks in advanced

You'll probably have to change the calls to getUserMedia in janus.js, as we don't use what our adapter defines: unless the Temasys plugin defines navigator.mediaDevices.getUserMedia?

That said, I have no idea what the error message in Spanish says. Besides, adapter and janus.js aside, our JavaScript code in the demos is probably something Internet Explorer will never like. I guess you'll have to change parts of that too, e.g., disabling all calls to console.log which IIRC doesn't exist on IE.

PS: also check if attachMediaStream is defined in the plugin adapter, as that's what we use to display the video.

Thanks Lorenzo, Temasys plugin defines navigator.mediaDevices.getUserMedia and attachMediaStream.

Sorry for the spanish message. That means: "SCRIPT28: Out of stack space".

Just checked line 182 of echotest.js and it seems harmless, though:

https://github.com/meetecho/janus-gateway/blob/master/html/echotest.js#L182

There's a

    if($('#myvideo').length === 0) {

Is that the line in your version as well, or do you have a modified version of the source?

L.

[Oscar Vadillo]

I am using the original version, maybe I put some alert at top, but nothing important sentence.

I think that the problem is with the method JSON.stringify in IE11. If I comment all lines with JSON.stringify it works, but in janus.js MUST use the stringify method for communicate with the gateway.

So the problem is here: https://github.com/Temasys/AdapterJS/issues/83

It isn't a problem about Janus but I will let know you when I resolved it.

Thanks Lorenzo

[Lorenzo Miniero]

IE doesn't have any stringify support? That's weird... looking around there seems to be a script you can use to do that though: http://www.json.org/js.html

L.

[Oscar Vadillo]

JSON.stringify does not support plugin objects.

This is not specific to the Temasys plugin; It's just that stringify doesn't know what a plugin object is.

Best case scenario it will fail on entering the function, worst case it will try and return the kind of errors you are facing now.

At the moment we don't have an elegant solution to this issue and don't want to release and maintain a bad solution.

We also don't see this as blocking issue because there are a lot of ways around (one can build a tree without JSON.stringify)

For these reasons, we don't plan on publishing a solution in the close future.

So I think that I will edit janus.js, replacing JSON.stringify method by one-by-one properties...
