Hello,

I am using mediasoup-client with the react-native-webrtc library. I am trying to implement a video conference application. In the conference, there are streams with vp8 and h264 codecs. If the h264 stream viewed on the RTCview first, all the h264 streams can be viewed. But I can’t see the vp8 streams on the RTCView and vice versa. There was no error in both libraries.

Do you have any suggestions guys 🙂

Thanks.
