Example
Given a video element with the ID "myVideo":
var v = document.getElementById("myVideo");
var buf = v.buffered;
var numRanges = buf.length;
if (buf.length == 1) {
// only one range
if (buf.start(0) == 0 && buf.end(0) == v.duration) {
// The one range starts at the beginning and ends at
// the end of the video, so the whole thing is loaded
}
}
This example looks at the time ranges and looks to see if the entire video has been loaded.
