A few weeks ago I got a germ of an idea in my head for a personal web-application that required recording and playing video, something with which I have had very little experience. I have seen how effortless is it to play video with HTML5 so I thought this would be simple. After searching countless sites looking for the HTML5 magic bullet for recording both audio & video, I had pretty much given up.
If you have stumbled upon this article also looking for a way to record audio & video together, you can stop searching now. I can say with fairly strong confidence that such a mechanism does not yet exist (as of the publish date of this article). However, I believe I have a workable solution for the time being.
The full source for the example application is on github.
