Firefox Video Tile Issues

See original GitHub issue

Scenario 1 : Tile Errors and Freeze

Timeline:

UserA joins as first user with Chrome and starts video
UserB joins as second user with Firefox 76 and starts video.
UserA turns video tile off and on several times.

On UserB’s Firefox console an error is thrown and tiles might freeze sometimes, either immediately or when UserA leaves the meeting.

Error thrown on Firefox:

ERROR: TypeError: this.removeTrackRemovedEventListeners[track.id] is not a function

Source of error: https://github.com/aws/amazon-chime-sdk-js/blob/5a9d8d0a6b6c0809c7a856a1e3da89b1706dfdb0/src/task/CreatePeerConnectionTask.ts#L263

Scenario 2 : Duplicate Tiles

Timeline:

UserA joins as first user with Chrome and starts video
UserB joins as second user with Chrome and starts video
User C joins as third user with Firefox and starts video

Bug: Four videos tiles will be displayed on Firefox, one of Chrome’s would be duplicated.

Note: Also happens if UserA shares video and screen and then Firefox joins, one of Chrome’s streams would be duplicated , either Video or Content.

Sample I’ve provided a sample app to replicate both issues, tested with latest version of the SDK (1.7.0) and with one and two machines:

The proper fix for this issue requires changes in our infrastructure as well as client side changes. The infrastructure changes are in the process of being deployed and will take some days to be fully deployed. Once those changes are fully deployed the client side changes will be merged to master.

Sorry for the wait.

The set of changes in #417 is to address the problem @rachinkapoor was seeing.

I have a handle on the problem described in scenario 1 and working on coming up with the best solution.
