What's the best way to load a different video background when user refreshes the page? I seem this done in flash but that's not what I want. Thank you.

I would do it this way:
Initialize a set of video sources in an array.
Randomly pickup a video among these sources using Math.random() and apply it to your webpage.
If you want different video after every refresh, save the source path in localStorage and check it after refresh.
Keep it simple. :)

Does anyone have a simple solution to extract frames from a gif using javascript?
I know some online tools like Ezgif and Gif-explode, but I'm wondering if this is also possible using just javascript?
For a client-side solution I'd recommend to have a look at libgif-js.
It allows to step to a specific frame in the GIF and you could then use the Canvas API to capture a single frame by drawing the image to the canvas and then getting the Data URL.

I am a beginner in Javascript.
I have two buttons (start and stop) controlling the flow of mediastream using WebRTC. How could I create a event handler for stop button, which would stop the mediastream.
The only reliable way I've found to do this is to change the src attribute to empty (or to some other URL).
Once you've changed the URL, the media will stop downloading in the background.
