This is an AngularJS directive for MJPEG streams. This directive uses an iframe to stop the browser from loading the MJPEG stream. This is useful for Chrome: https://code.google.com/p/chromium/issues/detail?id=73395

Thanks for this mjpeg directive, this is what I'm looking for.

Although there is no license mentioned, can you tell me which one it is so I know if and where I can use your directive ?

You are a star. I've been working on this bug for like a week straight. Adding the word "IONIC" to the comment thread so that people searching for ionic see this too. WOO HOO YOU RULE. :)

Nice code! There is one bug. When I use this this code, I cannot scroll in parent windows.

Change if (fDoc === document) { f.height = 0; f.height = document.body.scrollHeight; }
with
if (fDoc === document) { f.height = document.body.scrollHeight; }

Cheers!
