问题:

Video not working properly in the below mentioned code. What could be the problem for this?

MediaController mediaController = new MediaController(getBaseContext());
mediaController.setAnchorView(videoweb);

Uri video = Uri.parse("http://www.youtube.com/v/wwI2w2YHkCQ?fs=1");
videoweb.setMediaController(mediaController);
videoweb.setVideoURI(video);
videoweb.start();

Error:

Cannot play video
Sorry,this video cannot be played.

回答1:

The link you have provided, http://www.youtube.com/v/wwI2w2YHkCQ?fs=1, is for an HTML page. The URI to be provided for setVideoURI() should be a media file such as MP4 or AVI.

VideoView cannot parse a HTML page. It can only decode and play a video file or stream a video content (in this case the URI should point to the media file, such as http://people.sc.fsu.edu/~jburkardt/data/mp4/cavity_flow_movie.mp4). See Stack Overflow question Using VideoView for streaming or progressive-download video.

You should use a Webview for opening the YouTube link.



回答2:

VideoView and Mediaplayer can play only formats given in the document Android Supported Media Formats.

The link of the YouTube video you gave is for an HTML page. If you are playing an HTML page as mentioned by Karthik, it is better to use Webview.

String url = "your_youtube_link";
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));

If you want only the video to be viewed from that link, leave all other details in the page. Suppose this is the YouTube link http://www.youtube.com/watch?v=ZC7ZOGpM2cU&feature=g-logo&context=G233b464FOAAAAAAABAA

If you parse the source of the YouTube HTML page, you may see this portion:

<link rel="alternate" type="application/json+oembed" href="http://www.youtube.com/oembed?url=http%3A//www.youtube.com/watch?v%3DZC7ZOGpM2cU&amp;format=json" title="Bigg Boss 5: Juhi Parmar wins Big Boss season 5">
<link rel="alternate" type="text/xml+oembed" href="http://www.youtube.com/oembed?url=http%3A//www.youtube.com/watch?v%3DZC7ZOGpM2cU&amp;format=xml" title="Bigg Boss 5: Juhi Parmar wins Big Boss season 5">

<meta property="og:video:width" content="396">
<meta property="og:video:height" content="297">
<meta property="og:site_name" content="YouTube">

In this, extract the following

<meta property="og:video" content="http://www.youtube.com/v/ZC7ZOGpM2cU?version=3&amp;autohide=1">

In this, the <http://www.youtube.com/v/ZC7ZOGpM2cU?version=3&amp;autohide=1> link will show it fullscreen.



回答3:

Actually, in order to play any streaming video I am using

startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("http://www.youtube.com/v/wwI2w2YHkCQ?fs=1")));

But I don't think this is going to work for your link. Better to try

mediaplayer.setdataSource("your link").


回答4:

OK, try the following code. It will work.

Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse("http://www.youtube.com/v/wwI2w2YHkCQ?fs=1"));
startActivity(i);
