Restart youtube api

I need to upload, destroy and reload the YouTube Upload Widget , but unfortunately the reboot does not work.

I have completed the following steps:

  • I downloaded Youtube Upload Widget as described in the instructions
  • I am shooting a video from a webcam - it works
  • I destroy the widget with widget.destroy( ) - it works
  • I remove the script element from HTML - it works
  • I reload the API as in step 1 - nothing happens

Why is this not working?

onYouTubeIframeAPIReady() will only be called once per page when the window.YT.* interface is loaded through an external script. Removing the <script src="http://www.youtube.com/iframe_api"> element from the page and then re-adding it will not onYouTubeIframeAPIReady() again.

If you want to destroy the <iframe> that contains the download widget, then create a new widget placed in the new <div> that should work, but you shouldn't do it inside the onYouTubeIframeAPIReady() callback a second time. window.YT.UploadWidget() already available in this place, so feel free to use this interface directly from anywhere in your code.

onYouTubeIframeAPIReady () is called only once when the YouTube API loads. The answer is to add another check to step 2 of YouTube:

 if (typeof tag === "undefined") { // if first run load the YT API which will call the correct functions. var tag = document.createElement('script'); tag.src = "https://www.youtube.com/iframe_api"; var firstScriptTag = document.getElementsByTagName('script')[0]; firstScriptTag.parentNode.insertBefore(tag, firstScriptTag); } else { // if YT api already loaded, we need to call the function. onYouTubeIframeAPIReady(); }

Good luck.
