As far as I know, you can let the user open a file dialog from an <input type="file" /> (it's HTML), but you cannot specify what file types they can choose only from.

(In fact there is an "accept" attribute for <input type="file" /> which intended to give a similar effect ["User agents may use this information to filter out non-conforming files when prompting a user to select files to be sent to the server", from HTML 4 spec http://www.w3.org/TR/REC-html40/interact/forms.html#adef-accept], but it's useless at the moment.)

Of course you can, but the browser does not support it, i.e., the browser will not limit the user's choice to only Images & Videos.

You can try creating a sample webpage containing this. When you click on the "Browse" you can only see a file dialog with "All Files" shown.
