I’m trying to get the dimensions of a video of which I’m overlaying onto a page with JavaScript, however it is returning the dimensions of the poster image instead of the actual video as it seems it’s being calculated before the video is loaded.
Answer
<video id="foo" src="foo.mp4"></video>
var vid = document.getElementById("foo");
vid.videoHeight; // returns the intrinsic height of the video
vid.videoWidth; // returns the intrinsic width of the video
