On the Web platform, how to share system sound and microphone sound during screen sharing?

Web screen sharing can select the target window to share. Different platforms and different choices will have different performances:

• Windows system:

  • Share the entire desktop, can push out the system sound.
  • Share browser tabs, can only push out the sound of the tab.
  • Share other application windows, cannot push out the sound of the application.
  • Screen sharing cannot capture microphone sound. You need the SDK to push a second stream to push the sound captured by the microphone.

• Mac system:

  Cannot push out the system sound, can only push video data.
