RTCView shows nothing with the stream from mediasoup-client consumer

1

Hi,

I run a react-native android application which put (mediasoup-client) consumer’s stream url in RTCView, but no video is shown.

The environment in use is,

  • react: 16.9.0
  • react-native: 0.61.2
  • react-native-webrtc: 1.75.1 (latest version, confirmed with ibc)
  • mediasoup-client: 3.2.7 (latest version, confirmed with ibc)

Below is what been observed. What could be done further to debug the possible cause ?
Any advises are appreciated, Thanks !

  • no errors/exceptions is found in all API

  • mediasoup-client producer transport looks fine. Tcpdump shows that packets are flowing in the udp candidate ip/port of sendTransport.

  • mediasoup-client consumer transport looks fine. Tcpdump shows that packets are flowing in the udp candidate ip/port of recvTransport.

  • This application is based on mediasoup-sample-app (https://github.com/mkhahani/mediasoup-sample-app), and ported to react-native (android). The server side is verified working fine with mediasoup-client on win10 (using Chrome browser).

  • In server side, consumer.getStats() is added to see what happened, and looks fine, eg.,
    [
