Get OpenTok stream by ID

I am creating an app where I want a specific stream to be shown big on another page. There will be one page with all the streams (subscriptions) and one page which will show a SPECIFIC stream on the whole screen.

  1. Send the streamID of a chosen stream to the database.
  2. On the other page, fetch the last added streamID in the database
  3. Get stream by ID and show it on the page

I got the first two steps working, the last step is a problem. I somehow need to fetch a stream object by the given streamId. Is this possible? OR is there another way to achieve this?

You might not even need a database for what you are trying to do. Simply connect both pages (specific stream and all streams) to the same sessionId. You can put streamId in your url as a parameter like this: ?streamId=1343-thneue...

In your streamCreated event, simply check the stream.streamId in your callback function with your url streamId. If they match, then call session.subscribe on that stream object.

I dont know if this is the correct way to do it but you can add all the stream objects in an array:

var streamContainer = [];
session.on("streamCreated", streamCreatedHandler);

streamCreatedHandler = function(e) {
    streamContainer.push(e.stream)
}

and when your ID gets fetched unsubscribe from current, iterate over the array and subscribe to the new stream:

for(var i = 0; i < streamContainer.length; i++) {
    if(streamContainer[i].id == dbStreamId) {
        session.subscribe(streamContainer[i], 'DOMELEMENT', {options});
    }
}
