Supported Media Constraints

[b4oshany]

@steely-glint, @bverbol and @pigeonflight , Brian and I after a conversation with Tim tried to use the gain to control the volume for the microphone. It worked in Firefox and Chrome, even on the iMac, however, it didn't work in Safari desktop nor mobile. You can try the isolated sample demo or review the code.

In addition, we created an isolated demo sample that pre-process the audio stream before sending it, but it didn't work on Safari desktop nor mobile.

Due to this, I created another sample demo, which outputs the supported media constraint for the user browser. In the screenshot below, Safari does not have support for AutoGainControl, which might imply that the gainNode object is not fully supported in Safari.

At this point, I am running out of ideas to resolve the iPhone/Safari issue.
