hey guys, great work with chromeless! not sure if this is the right place to ask questions but i'll give it a try: i am trying to use chromeless to remotely start a headless chrome on aws to test a webrtc service app and for this i need chrome to play a fake video as webcam using flag --use-file-for-fake-video-capture. i cant find where chromeless starts the remote chrome to insert the flag... can anyone help?
