websocket Javascript Multi-Stream Video Player page

I need an experienced JavaScript developer to modify a video player page playtest.html for viewing multiple streams simultaneously.

To transmit use the : transmit_test.html page, it will connect to antmedia community server
to transmit multiple feeds :
transmit_test.html?streamid=user1
transmit_test.html?streamid=user2
etc

Currently, the page playtest.html can only play one stream due to its connection to a single websocket and video element. The objective of this project is to adapt the page to allow for multiple video players/websockets loading in a designated div.

I am not using the antmedia room feature because i need more flexibility in processing the feeds.

Key Requirements:
- Modify the playtest.html page to enable viewing of multiple streams at once
- Ensure all streams can be viewed simultaneously

The ideal candidate for this project should have:
- Proven expertise in JavaScript
- Previous experience with WebSocket and video player in javascript
- Familiarity with AntMedia Video Server is a plus
