I have read similar questions posted but none did help my case.

Here is my YouTube iframe:

<iframe id="myframe" style="border: solid 4px #37474F; ">
</iframe>

I added the src attribute dynamically.

Here is my player:

var player;

function onYouTubeIframeAPIReady() {
  player = new YT.Player('myframe', {

    events: {
      'onReady': onPlayerReady,
      'onStateChange': onPlayerStateChange
    }
  });
}

I am trying to do player.getCurrentTime(); and player.getDuration(); but both keep giving the "function not defined" error.

The YouTube player API sets player.getCurrentTime not in the constructor but later (possibly when the video is loaded). Likely, this is a bug.

To see that this is true add console.log(player.getCurrentTime) before each call. You will see that this is undefined initially and later changes to a function.

Work around this by testing whether player.getCurrentTime exists. If not, assume a return value of 0.0. Example:

var videoPos = !player.getCurrentTime ? 0.0 : player.getCurrentTime();

The same problem seems to happen with getDuration.

As usr said, it's likely a bug. And here's another solution:

var yourVariable = player.getCurrentTime() || 0;
