Multiple Video Tracks Issue

Hi everyone,

I’m currently implementing a feature that can send multiple video camera tracks in one session only. What I have done is get all video MediaStreamTrack and add it to the MediaStream and try to send it via peer connection through JVB. But I got these errors.

Has anyone been in this situation? Or can anyone tell me what I did wrong?
Thank you in advance!

Chinese programmer?
