Thank you Daniel for your precious help! I also found a way to use a YouTube Video that would work with DFP. Using Inner HTML and a script like this will do it:
<div id="player"></div>
<script>
// 2. This code loads the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// 3. This function creates an <iframe> (and YouTube player)
// after the API code downloads.
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
width: '404',
height: '227',
videoId: 'phOul5I4pIU',
playerVars: {rel: 0, autoplay: 1, controls: 1, modestbranding: 1, showinfo: 1, muted: 1, autohide: 1, loop: 1, playlist: 'phOul5I4pIU'},
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {
event.target.setVolume(0);
event.target.playVideo();
}
// 5. The API calls this function when the player's state changes.
// The function indicates that when playing a video (state=1),
// the player should play for six seconds and then stop.
var done = false;
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.PLAYING && !done) {
// setTimeout(stopVideo, 6000);
done = true;
}
event.target.setVolume(0);
}
</script>
</div>
