2. Two cameras support (almost done)
3. On/off camera track transmission (track.enabled=true/false)
4. suppress black screen of disabled video at the receiver (videoelement.display.style = 'none' to suppress, '' to recover)

with customized SkyWay JS SDK

• Fix SDP parameter for opus (stereo=1;maxaveragebitrate=256000)
• addTrack(), removeTrack() support (also replaceTrack() but not tested)
• videoBandwidth, audioBandwidth in the middle of a session
  Note: audioBandwidth does not work for Firefox (sending side)

How to use

1. Open two instances of this application (on two PCs). Using two browers on a PC is OK for a basic experiment.
2. Connect additional camera (webcam) before "call" or accept a call.
3. Choose cameras and audio input devices.
4. Caller: Copy "localPeerId" of the other party to "remotePeerId" text field, then press "Call".
   • All peer names are listed in JavaScript Console of the browser.
5. Callee: "Call" becomes "Answer" when called, then click.
6. No hangup button available now (to be added). Just close the brower tab.
