SidelineCAM can use advanced HEVC video compression on Apple devices.  HEVC (also called H.265) offers the same quality at 1/2 of the bandwidth!

Follow these steps to activate "WebRTC HEVC" in iOS:

Note: This feature is only available in iOS Safari.

Go to SETTINGS >> Safari >> Advanced >> Experimental Features (or Feature Flags) >> WebRTC H265 Codec

That's a mouthful.  Or just do this:

When done, click REFRESH on sidelineCAM.  You should see a menu where you can select HEVC.
