I am currently working at a project where I have to draw stuff over a live video feed coming from a TV set via HDMI (at 1920x1080). Of course this will need a separate piece of hardware to be connected, and an advice about it would be very welcome.
Has anybody already tried something like this (I suppose so) and is willing to help?
So far I tried the Avermedia Live Gamer Portable, but couldn’t manage to make it work properly. It needs a separate software to decode its proprietary protocol and present it as a webcam, and for some reason only the first frame after connecting the HDMI cable can be read from ofVideoGrabber.
Peeking among the extensions I found a few for the Blackmagic series, can somebody give me a hint about which is the cheapest device capable to do the job? The system should be installed in public places (like bars and clubs) so it would be better to avoid expensive and sophisticated hardware if possible.
Unfortunately I am working on a tight budget (out of my own money) and cannot afford to buy several devices to choose among them.
Thanks for helping and all the best,
