iOS local video stream exists in remote client but no bytes sent in RTCLegacyStatsReport
I am using cocoapods GoogleWebRTC in Swift. I am receiving the audio and video remote stream, My local audio stream is sending bytes okay but my local video stream has no bytes sent even when added to videotrack was already added to local media stream. Looking thought chrome webrtc internals, the remote client also received the local audio and video stream but no bytes sent being received for video in iOS client.

As you can see from the logs of video stats, bytesSent is 0. I am using iPad mini version 11.2.2 as my iOS test device. Any idea why there is no bytes sent at all? The remote client is web and there’s no remote ios video showing which is caused by no bytes sent. Thanks.
