I would like to stream the video that I being output on my HDMI via USB-C, instead of streaming the content shown on my screen. Specifically Djay for IPad by Algoriddim allows you to connect an external monitor but keeps the apps control view while sending the video to the HDMI instead of sending the mirror (option exists for either mirror or full video content in the app). I would like Twitch to have access and an option to select the HDMI output to stream for this app.
