I am completely new to this but am a developer. I'm trying to make a web app, just for personal use, that will allow me to record the screen and save it to a flash drive. I've been searching through all the docs and can only find things on recording audio. I want to record audio and video from the HDMI input. My goal is to be able to plug in a playstation 1 to my TV and record my gameplay onto a flash drive. Right now I am trying to make some javasript functions that will do so.
If anyone could lead me in the right direction that would be so nice. Thank you.
