composite video capture to artnet pixel mapping over ethernet

Fri Aug 23, 2019 10:51 pm

does anyone know if it is possible to capture analog composite video with a usb capture dongle or something like this: https://lintestsystems.com/products/picapture-sd1 and then map those to an led pixel wall over artnet/ethernet?

i have built a massive 8'x8' led pixel wall with 2,300 addressable pixels using the F16V3 ( https://www.pixelcontroller.com/store/i ... er=product ) and i would like to be able to map analog video from an LZX video synth to the wall. i can easily map video captured with a usb card and madmapper, but i would like to eliminate the laptop and only use a small dedicated raspberry pi setup if it's possible.

Regards USB Capture "EasyCap" Dongle then STK1160 are cheap and supported under Linux:

thank you, i have seen the easycap dongles but i believe they add latency. is it possible to pixel map that live feed (not a prerecorded clip) onto led’s over artnet?
