title: Problem Using the usb camera in mobile to stream agora video
body: <p>I am using Agora for the live streaming from phone using USB camera to the desktop using mobile app. I have tried the same with flutter But It's not recognizing the USB camera. Now I am using the platform specific app for the same. So now I am using android for the same but again I got the error from Agora
  <code>not supported</code> I am not getting that how to fix that. If there is any alternate for the same please let me know.</p>
