iOS - Not able to render Remote videoTrack and audioTrack

Hi guys,

I’m following the mediasoup-ios-client-demo app. When I join the room, users in Chrome are able to see and listen to iOS client, but the remote videoTrack and audioTrack in iOS are not rendered, it displays a black screen. I did receive the audioTrack and videoTrack from the server. (code and codecs are attached below)

There was an issue with socket in this demo. It solved.
