The problem may be with jquery selector you ve chosen $("video") is not a selector

The right selector may be putting an id element for video tag i.e.
Let s say your video element looks like this:

<video id="vid1" width="480" height="267" oster="example.jpg" durationHint="33"> 
    <source src="video1.ogv" /> 
    <source src="video2.ogv" /> 
</video> 

Then you can select it via $("#vid1") with hash mark (#), id selector in jquery. If a video element is exposed in function,then you have access to HtmlVideoElement (HtmlMediaElement).This elements has control over video element,in your case you can use pause() method for your video element.

Check reference for VideoElement here.
Also check that there is a fallback reference here.

If you want to stop every movie tag in your page from playing, this little snippet of jQuery will help you:

$("video").each(function () { this.pause() });

Starting Video with different browsers

For Opera 12

window.navigator.getUserMedia(param, function(stream) {
                            video.src =window.URL.createObjectURL(stream);
                        }, videoError );

For Firefox Nightly 18.0

window.navigator.mozGetUserMedia(param, function(stream) {
                            video.mozSrcObject = stream;
                        }, videoError );

For Chrome 22

window.navigator.webkitGetUserMedia(param, function(stream) {
                            video.src =window.webkitURL.createObjectURL(stream);
                        },  videoError );

Stopping video with different browsers

For Opera 12

video.pause();
video.src=null;

For Firefox Nightly 18.0

video.pause();
video.mozSrcObject=null;

For Chrome 22

video.pause();
video.src="";

The following works for me:

$( video )[0].pause();

Someone already has the answer.

$( video ) will return an array of video items. It is totally a valid seletor!

so

$("video").each(function () { this.pause() });

will work.

For a JQM+PhoneGap app the following worked for me.

The following was the minimum I had to go to get this to work. I was actually experiencing a stall due to the buffering while spawning ajax requests when the user pressed the back button. Pausing the video in Chrome and the Android browser kept it buffering. The non-async ajax request would get stuck waiting for the buffering to finish, which it never would.

Binding this to the beforepagehide event fixed it.

 $("#SOME_JQM_PAGE").live("pagebeforehide", function(event)
 {
           $("video").each(function () 
           { 
               logger.debug("PAUSE VIDEO");
               this.pause();
               this.src = "";
           });
 });

This will clear every video tag on the page.

The important part is this.src = "";

My experience with Firefox is that adding the id attribute to a video element causes Firefox to crash completely...as in asking you to submit a bug report. Remove the id element and it works fine. I am not sure if this is true for everyone, but I thought I d share my experience in case it helps.

To save hours of coding time, use a jquery plug-in already optimized for embedded video iframes.

I spent a couple days trying to integrate Vimeo s moogaloop API with jquery tools unsuccessfully. See this list for a handful of easier options.

Try this:

if ($.browser.msie)
{
   // Some other solution as applies to whatever IE compatible video player used.
}
else
{
   $( video )[0].pause();
}

But, consider that $.browser is deprecated, but I haven t found a comparable solution.
