    Sure,

    1. You can set the src attribute on the source element:

      document.querySelector("#myVideoTag > source").src = "http://example.com/new_url.mp4"

      Or using jQuery instead of standard DOM methods:

      $("#myVideoTag > source").attr("src", "http://example.com/new_url.mp4"​​​​)​

    2. Then you need to call the load method on the video element:

      videoElement.load()
