Question

Do you have any idea why I’m getting an error “Can’t create event listener of null” from this:

    var my;
    my.newVidObj = document.createElement('video');
    my.newVidObj.src = "vid-source.webm";
    my.newVidObj.load();        
    my.newVidObj.addEventListener("play", function() {
        // Do something
    }, false);  

Also, is there any way to use video tag methods on jquery objects (creating the video tag via jquery, for example)?

I edited the below answer to be correct, but it needs to be peer reviewed. Here is the solution:

var vid = $("<video />", {
    id: "my-HTML5-video",
    src: "video.webm"
}).bind("play", function(){
    alert('test');
}).appendTo("body")[0].play();

I think it should be:

var vid = $("<video />", {
    id: "my-HTML5-video",
    src: "vid-source.webm",
});

vid.appendTo("body");

vid[0].play = function(){
    alert("yaaay!");
};

Correction by OP:

var vid = $("<video />", {
    id: "my-HTML5-video",
    src: "video.webm"
}).bind("play", function(){
    alert('test');
}).appendTo("body")[0].play();
