Can html 5 serve real time media stream?

Question

I've heard of many interesting features of html 5,

but is it able to serve real time media stream from web camera?

Answer 1

This has nothing to do with HTML 5, actually. In HTML you just point the browser to a resource, specifying it's video. If your camera emits a stream in a format the browser is able to render, then it should work, sure. Though in my experience many cameras yield MJPEG and support for that directly in browsers appears to be limited at best.

Answer 2

Not html5 on it's own but html5 video can read streams(like on youtube, live streaming).

Answer 3

HTML5 video is just a tag that looks like

<video src="movie.mp4" controls="controls">
    Your browser doesn't support the video tag.
</video>

(reference here)

Whatever that movie.mp4 actually contains is decided by the underlying server and may be streaming content as long as the format itself supports streaming. For example h.264's eXtended Profile and Scalable High Profile both support video streaming.

Answer 4

I did the proof for this a few days ago. The answer is yes and no. Yes the XMLHttpRequest allows you to access the data while it is streaming from the camera. No it is not supported across all browsers.

In a XMLHttpRequest you can get status messages from the object when done asynchronously. Problem being that each browser handels this a little diffrent. The big problem is that even though Internet Explorer dose support the update to the status if you try to access the data in state 3 it will give an error. For more info please follow the link.

If your camera can send a video stream that is a standard media type like the other posters have been saying then that would be your best option. Maybe after the release of IE 9 will the XMLHttpRequest work as assumed.
