YouTube Player API: How to get duration of a loaded/cued video without playing it?

Question

I\'m not able to get the correct video duration/length (in seconds) of a loaded/cued video via the getDuration() method of the YouTube Player API; the same method, however,

Answer 1

"Loading, and immediately playing and pausing the player would be not my favorite method."

I don't think there is any other method.

In my case it works well, even for a satellite internet user.

Here is my code :

// I set youtube player-ready event to a variable for irrelevant reasons
function onYouTubePlayerReady(playerid) { 
    youtube_player_ready;
}
youtube_player_ready = function(playerid) {

    // load video
    document.getElementById(playerid).cueVideoById(yt_video_id);
    // mute video
    document.getElementById(playerid).mute();
    // play video to get meta data
    document.getElementById(playerid).playVideo();

    yt_get_duration[index] = function(){
        // if duration is available
        if (document.getElementById(playerid).getDuration() > 0) {
            // pause video
            document.getElementById(playerid).pauseVideo();
            // unmute
            document.getElementById(playerid).unMute();
            // save duration
            video_duration = document.getElementById(playerid).getDuration();

        }
        // else keep trying
        else {
            setTimeout(yt_get_duration[index], 150)
        }
    }
    // get duration
    yt_get_duration[index]();

}
