canvas stream - fail event

[seobi]

Hello.
I'm testing the canvas stream with the latest version you provided. However, a failure event occurs on the second connection attempt.
As shown in the following log, it will run normally on the first attempt. However, it fails at the second attempt and cannot stream.
I would appreciate if you let me know what I am doing wrong.
Best regards.

We raised ticket WCS-2402. Will will let you know once we have any news.

Good day.
Unfortunately, we cannot reproduce the issue you describe, so please clarify the following:
1) Your test environment: OS, browser
2) WCS version, WebSDK version (probably the latest with Canvas Streaming example fix)
3) Does the issue occurs using Canvas Streaming example without any changes? If not, please provide us a minumally customized code example to reproduce the issue to support@flashphoner.com, we will check

 

[seobi]

I just sent you an email.

 

[Max]

Good day.
Thank you, we received code example from you. We will check.

 

[Max]

Good day.
We've checked your code and found the reason for this issue. There ia the following code in FPStream.js:

sunny.startCanvasStream = async function(stream) {
    FPStream.initialize();
    FPStream.connect(sunny.MEDIASERVER);

    document.addEventListener('onMediaServerConnected', async function (e) {
        var constraints = { audio: false, video: false }
        FPStream.startStreaming(sunny.STREAMKEY, constraints, stream);
    });

    document.addEventListener('onMediaServerDisconnected', function (e) {
    });
}

We added listener removing:

unny.startCanvasStream = async function(stream) {
    FPStream.initialize();
    FPStream.connect(sunny.MEDIASERVER);


    var onMediaServerConnectedListener = async function (e) {
        var constraints = { audio: false, video: false }
        FPStream.startStreaming(sunny.STREAMKEY, constraints, stream);
    };

    document.addEventListener('onMediaServerConnected', onMediaServerConnectedListener);

    document.addEventListener('onMediaServerDisconnected', function (e) {
        document.removeEventListener('onMediaServerConnected', onMediaServerConnectedListener);
    });
}

Then, second canvas stream publishing works after previous unpublishing. Please, apply the changes described above and check.

I realized it was my stupid mistake.
Thank you for the reply.

I've also asked you a question about e-mail, but I'll ask you a question separately because it's different from this issue.
Thank you very much.
