Fixed #530 - Now you can pass "elementClass" parameter.
Browse files Browse the repository at this point in the history 
let recorder = RecordRTC([streams], {
   type: 'video',
   elementClass: 'your-custom-class'
});

Now you can access <canvas> element anytime using this:

document.querySelector('.your-custom-class').style.opacity = 0;

Why did you use the module.exports = something twice?, There have another module.exports where above RecordRTC.

MultiStreamsMixer is a separate project: https://github.com/muaz-khan/MultiStreamsMixer

That's why I'm using this:

if (typeof RecordRTC === 'undefined') {
    if (typeof module !== 'undefined' /* && !!module.exports*/ ) {
        module.exports = MultiStreamsMixer;
    }

    if (typeof define === 'function' && define.amd) {
        define('MultiStreamsMixer', [], function() {
            return MultiStreamsMixer;
        });
    }
}

Exactly here: https://github.com/muaz-khan/MultiStreamsMixer/blob/master/dev/tail.js#L11-L21
if (typeof module !== 'undefined' /* && !!module.exports*/ ) {
module.exports = MultiStreamsMixer;
}

if (typeof define === 'function' && define.amd) {
define('MultiStreamsMixer', [], function() {
return MultiStreamsMixer;
});
}
