正如你已经注意到你所提供的链接，你不能运行在iOS动作主权财富基金。它不会很长之前，不会有任何的方式来做到这一点在Android上，无论是。 VideoDisplay的也将无法正常工作，因为，它的动作。
要在iOS上播放YouTube视频，你可以使用（如应用程序，你提到的和iOS上其他YouTube为基础的应用程序做）的的本机的Objective-C库的，这将对获取播放列表和播放视频的全面支持;或者也可以尝试使用JavaScript客户端的web应用程序。
I am trying to fetch youtube playlist and play videos on IOS. My app works fine on Android and Flex simulators but does not work on IOS. Looks like there is a limitation on loading swfs in IOS here.
I am using as3-youtube-data-api for the purpose. Can anyone guide me on how can I embed or play youtube videos using as3 (Flash Builder 4.5) on IOS or is there any other way available?
Note: There is "Cisco Technical Support" app in app store, which plays youtube videos embedded in the app.
Update can VideoDisplay work, as I do not have mp4 for my playlists?
More Update
this is how at least m able to play youtube videos on IOS (read this), but again android gives me a black screen. Is there something I can do with this approach? Please give your suggestions. Thanks
var webView:StageWebView;
public function init():void
{
NativeApplication.nativeApplication.systemIdleMode = SystemIdleMode.KEEP_AWAKE;
webView = new StageWebView();
webView.viewPort = new Rectangle( 0, 35, this.stage.stageWidth, this.stage.stageHeight);
webView.stage = this.stage;
var htmlString:String = "<!DOCTYPE HTML>" +
"<html><body><script>" +
"var tag = document.createElement('script');"+
"tag.src = \"http://www.youtube.com/player_api\";"+
"var firstScriptTag = document.getElementsByTagName('script')[0];"+
"firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);"+
"var player;"+
"function onYouTubeIframeAPIReady() {"+
"player = new YT.Player('player', {"+
"events: {"+
"'onReady': onPlayerReady,"+
"'onStateChange': onPlayerStateChange"+
"}"+
"});"+
"}"+
"function onPlayerReady(event) {"+
"event.target.playVideo();"+
"}"+
"var done = false;"+
"function onPlayerStateChange(event) {"+
"if (event.data == YT.PlayerState.PLAYING && !done) {"+
"setTimeout(stopVideo, 6000);"+
"done = true;"+
"}"+
"}"+
"function stopVideo() {"+
"player.stopVideo();"+
"}"+
"</script>"+
"<iframe id=\"player\" type=\"text/html\" width=\"100%\" height=\"400\" src=\"http://www.youtube.com/embed/g-YW2jkd-Ac\" frameborder=\"0\"></iframe>" +
"</body></html>";
webView.loadString( htmlString );
//webView.loadURL("http://www.youtube.com/embed/M7lc1UVf-VE");
}
public function dispose():void {
try {
webView.stage=null;
} catch (e:Error) { trace("error")}
}
Using Capabilities.os I can identify the OS and work my way through IOS and android.
Again, we cannot invoke javascript in IOS, so I am unable to stop the video.
Update
This is what I did for IOS. It gives in built player controls
public function initIOS():void
{
NativeApplication.nativeApplication.systemIdleMode = SystemIdleMode.KEEP_AWAKE;
webView = new StageWebView();
webView.viewPort = new Rectangle( 0, 40, this.stage.stageWidth, this.stage.stageHeight-40);
webView.stage = this.stage;
webView.loadURL("http://www.youtube.com/embed/"+data.videoId+"");
}
As you've noted with the link you provided, you can't run actionscript swfs on iOS. It won't be long before there won't be any way to do it on Android, either. VideoDisplay also won't work because, well, it's actionscript.
To play Youtube videos on iOS, you can use (as the app you mentioned and other youtube-based apps on iOS do) the native Objective-C libraries, which will have full support for fetching playlists and playing videos; or could also try using the javascript client in a webapp.
