(Screen-) Record multiple iOS devices with CoreMediaIO

I am currently trying to achieve live streaming of iOS devices. I would like to use AVFoundation / CoreMediaIO from Mac via cable ( https://nadavrub.wordpress.com/2015/07/06/macos-media-capture-using-coremediaio/ ).

CoreMediaIO only supports one device at a time (source: https://nadavrub.wordpress.com/2015/07/06/macos-media-capture-using-coremediaio/ ).

Is there a way to remove the limitation on one CoreMediaIO device?

Thank you in advance!
