How to record, store, and loop live video input from a Canon DSLR?

The library for reading video from a camera, playing back video, and creating video is Video, with the Movie object. It is built-in to Processing and comes with some example sketches to get started.

Keep in mind that if you are trying to play back a wall of thousands of video clips then there are a lot of hardware and software considerations to make it technically feasible -- in that case, a Java-based language might not be the best choice for you, and you might want something like OpenFrameworks.

Is your application concept as intensive as the example you shared?

Hi Jeremy, Thank you for getting back to me. When I run this code while my Canon 5D mark iii DSLR is connected via USB, Processing doesn't 'print' that the DSLR is 'available' to use:

import processing.video.*;

Capture cam;

void setup() { size(640, 480);

String[] cameras = Capture.list();

if (cameras.length == 0) { println("There are no cameras available for capture."); exit(); } else { println("Available cameras:"); for (int i = 0; i < cameras.length; i++) { println(cameras[i]); } } }

Any ideas on a solution around this?

In regards to your second comment, I am looking to create a sketch that captures 10-16 video clips—not 1000+ as shown in the example.

You cannot directly acces a DSLR camera the way you acces your build in camera or an external usb camera, but there might be some libraries that will allow you acces: https://forum.processing.org/two/discussion/6566/announcing-edsdk-processing-canon-slr-plugin-for-windows
