Problem "video unvailable" with Youtube on iOS only

Hi everyone,

I have a problem with Youtube video on iOS. Like you can see :

I use sanitizer :

async ngOnInit() {
   = this.getSanitizedUrl();

getSanitizedUrl() {
        let id_yt = this.navParams.get('id_yt');
        return this.sanitizer.bypassSecurityTrustResourceUrl('' + id_yt);

front :

<iframe id="player" width="560" height="315" [src]="video" frameborder="0" allowfullscreen></iframe>

but it’s not working on iOS.

Do you have some ideas ?
