how to make getUserMedia() work on all browsers

Question

I learn about web-rtc, it says that you can capture video-cam , i used demo , well this worked on chrome only..

when i open it on firefox i get mess

Answer 1

getUserMedia needs to be prefixed with webkit- or moz-. The first example is only prefixed with webkit-. Therefor it will never work on Firexox, only Chrome and Safari.

The code example does not show the prefix...

Prefixing can be done in this way:

navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia;
