Media12899 Audio/Video: Unknown MIME type when I stop video

[Tim McClure]

My web page is using the Temasys plugin in IE 11.  The video is displaying fine but when I close the video I get the following exception:

MEDIA12899: Audio/Video : Unknown MIME type

Below is the code I use on the stop.  The code works in Chrome.  I need to be able to reuse the videoOutput because of my retry logic - sometimes it take more than 1 try to get the video.

Tim

 stop: function () {
        videoOutput.pause();
        if (webRtcPeer) {
            webRtcPeer.dispose();
            webRtcPeer = null;
        }
        if (pipeline) {
            pipeline.release();
            pipeline = null;
        }
        kClient.close();
        hideSpinner(videoOutput);
    }
}

Hi,

Your stop function doesn't look bad to me, as long as you call videoOutput.play later.

Are you using videoOutput = attachMediaStream(videoOutput, stream) to play your streams ?

[Tim McClure]

I am using kurento utils which does the following - it does not set the videoOutput to the returned value - do you think I should change this?  The code:

function setRemoteVideo() {
    if (remoteVideo) {
        var stream = pc.getRemoteStreams()[0];
        remoteVideo.pause();
        attachMediaStream(remoteVideo, stream);
        remoteVideo.load();
    }
}

Yes, you need to do that.

Same thing for your local stream.

For the plugin, we need to replace the video element with an object element (that;s done in AdapterJS).

When we do that, your reference to remoteVideo is removed from the DOM and thus, needs to be updated. 

See the plugin doc for more info http://confluence.temasys.com.sg/display/TWPP/How+to+integrate+the+Temasys+WebRTC+Plugin+into+your+website

Cheers,

J-O

I made the change you suggested.  The code is below - the object returned does not have a load method so I get an error.  I will try taking it out the remoteVideo.load() line - does this make sense? 

function setRemoteVideo() {
    if (remoteVideo) {
        var stream = pc.getRemoteStreams()[0];
        remoteVideo.pause();

        remoteVideo = attachMediaStream(remoteVideo, stream);
        remoteVideo.load();
    }
}

[Jacques-Olivier Haché]

You don't need to run load.

[Tim McClure]

Thx that worked - I have implemented a retry loop to start the webrtc negotiation it I do not get video in a certain timeframe - the retry dies with in IE because I guess you change the video DOM element.  Any recommendations to get around this besides reloading the page?

[Jacques-Olivier Haché]

Again, please read the documentation. Most likely your issue is that you don't wait for the plugin to be loaded in memory. Have a look at AdapterJS.webrtcReady
