Webcam to canvas or data URI with HTML5 and Javascript

10 years ago

This post has been sitting around unfinished since April so I thought I should finish it and get it out there.

In this post I am going to show how you can capture an image from a webcam via JavaScript and convert it to a Data URI which can then be saved in a database or displayed in an IMG tag.

Note: This is more of a proof of concept rather than a best practices example so the code is a bit messy and hacked together from various sources.

I have only tested this on Safari for iOS 6 and latest Chrome with a webcam. It may or may no work in other browsers.

All explanations for the the code and markup are in the code comments, so please read them for more detail.

Creating HTML5 widgets for Adobe Captivate 6/7

These two versions are packaged up into a .wdgt file which is just a zip file with the extension changed to wdgt.
