Adding multiple video tracks to a peer connection sends duplicate streams

[umesh-timalsina]

Adding multiple video tracks to a peer connection causes the tracks to be duplicated in the browser (Basically, always the last added track). Starting with the webcam example, I have modified the front-end and server code in the following repository.

Basically, for each track in the comma-separated list of arguments for video sources, we create a media player and return video tracks for each source. In the client side, before negotiation, we add the necessary transceivers to the peer connection and add streams per track event in a new video element. However, each stream (even coming from a different track), plays the same video.

I believe that you get the same video because you only get index 0 on tracks from the stream. You can see this in your code at this link:
client.js#L75.

Hi @marcus2vinicius. That's true. However, the track events are fired independently. If I start the stream.py with two videos from the CLI, we get 2 track events. Albeit, the tracks have overlapping videos. If you see stream.py#L81.
