Question

我正在开发一个Android应用程序，需要在其中嵌入youtube视频播放器。我成功地从API获得了RTSP视频URL，但在我的Android视频视图中尝试加载此rtsp网址时，它显示“Can't play this video.”。以前我在这个方法中开发了一个类似的应用程序，当时工作正常，但现在也无法加载。

我很确定，我从API获得了正确的RTSP网址。 rtsp://v6.cache6.c.youtube.com/CiULENy73wIaHAlV9VII3c64lRMYESARFEgGUglwbGF5bGlzdHMM/0/0/0/video.3gp

这是我的活动代码：

    mVideoURL = getIntent().getStringExtra("EXT_URL");
    Log.i("VIDEO URL", " " + mVideoURL);

    MediaController mc = new MediaController(this);
    mVideoStreamView = (VideoView) findViewById(R.id.vidPlayer);

    mVideoStreamView.setVideoURI(Uri.parse(mVideoURL));
    mVideoStreamView.setMediaController(mc);
    mVideoStreamView.requestFocus();
    mVideoStreamView.start();

修改从logcat中找到了一些额外的信息：

请建议我在Android视频视图中加载youtube视频。

提前致谢...

修改刚刚检查了另一台设备HTC Desire（2.2）。代码工作正常。我想知道，Nexus（4.1）会出现什么问题？

Answer 1

由于我找不到任何方法在视频视图中加载rtsp URL（对于所有设备和Android版本），我解决了我的另一个问题。我使用webview将youtube播放器嵌入其中，这种方法可以很好地适用于所有经过测试的设备。

这是我的代码：

mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setPluginState(PluginState.ON);
mWebView.loadUrl("http://www.youtube.com/embed/" + videoID + "?autoplay=1&vq=small");
mWebView.setWebChromeClient(new WebChromeClient());

非常感谢你所有的帮助。

Answer 3

由于当前版本的YouTube，如果您使用VideoView来展示您的视频，则可能会出现“无法播放此视频”错误。

使用YouTubePlayerView查看此approcach： http://xinyustudio.wordpress.com/2014/03/17/android-development-play-youtube-video-in-your-app-cant-play-this-video-and-troubleshooting/

Answer 4

使用YouTube Android Player API。它完美地运作。从这里查看我的例子：

activity_main.xml中：

 <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"

tools:context="com.example.andreaskonstantakos.vfy.MainActivity">

<com.google.android.youtube.player.YouTubePlayerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:visibility="visible"
android:layout_centerHorizontal="true"
android:id="@+id/youtube_player"
android:layout_alignParentTop="true" />

<Button
android:text="Button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="195dp"
android:visibility="visible"
android:id="@+id/button" />


</RelativeLayout>

MainActivity.java：

package com.example.andreaskonstantakos.vfy;


import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import com.google.android.youtube.player.YouTubeBaseActivity;
import com.google.android.youtube.player.YouTubeInitializationResult;
import com.google.android.youtube.player.YouTubePlayer;
import com.google.android.youtube.player.YouTubePlayerView;



public class MainActivity extends YouTubeBaseActivity {

YouTubePlayerView youTubePlayerView;
Button button;
YouTubePlayer.OnInitializedListener onInitializedListener;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

     youTubePlayerView = (YouTubePlayerView) findViewById(R.id.youtube_player);
     button = (Button) findViewById(R.id.button);


     onInitializedListener = new YouTubePlayer.OnInitializedListener(){

         @Override
         public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {

            youTubePlayer.loadVideo("Hce74cEAAaE");

             youTubePlayer.play();
     }

         @Override
         public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {

         }
     };

    button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

youTubePlayerView.initialize(PlayerConfig.API_KEY,onInitializedListener);
        }
    });
}
}

和PlayerConfig.java类：

  package com.example.andreaskonstantakos.vfy;

/**
 * Created by Andreas Konstantakos on 13/4/2017.
 */

public class PlayerConfig {

PlayerConfig(){}

public static final String API_KEY = 
"xxxxx";
}

将“Hce74cEAAaE”替换为https://www.youtube.com/watch?v=Hce74cEAAaE的视频ID。从Console.developers.google.com获取API_KEY，并将其替换为PlayerConfig.API_KEY。有关任何进一步的信息，您可以一步一步地遵循以下教程：https://www.youtube.com/watch?v=3LiubyYpEUk

Answer 5

使用视频观看：

1.在布局xml中编码：

<VideoView

       android:layout_width=”wrap_content”

       android:layout_height=”wrap_content”

       android:id=”@+id/YoutubeVideoView” />

2.Code in java class：

VideoView v = (VideoView) findViewById(R.id.YoutubeVideoView);

v.setVideoURI(Uri.parse(“rtsp://v4.cache3.c.youtube.com/CjYLENy73wIaLQlW_ji2apr6AxMYDSANFEIJbXYtZ29vZ2xlSARSBXdhdGNoYOr_86Xm06e5UAw=/0/0/0/video.3gp”));

v.setMediaController(new MediaController(this)); //sets MediaController in the video view

// MediaController containing controls for a MediaPlayer                            

v.requestFocus();//give focus to a specific view

v.start();//starts the video

我们通过为移动平台指定Youtube视频的3gp链接来设置VideoUri。要添加媒体控件，如播放，暂停，倒带，快进和进度滑块，我们将MediaController添加到VideoView。

uri.parse（视频的3gp链接）...你可以从youtube获得这个

Answer 6

结帐link。它解释了如何在VideoView中实现YouTube视频。

Answer 7

这取决于您收到rtsp的视频编解码器格式。某些设备不支持运行.mp4文件。有关详细信息，请浏览Android Media support。检查您是否可以播放任何其他.3gp文件。

Answer 8

经过长时间的搜索，我发现了这种实现方式。

 public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.about_fragment, container, false);

    String frameVideo = "<html><body><br><iframe width=\"320\" height=\"200\" src=\"https://www.youtube.com/embed/XDYbEuY8nIc\" frameborder=\"0\" allowfullscreen></iframe></body></html>";

    WebView displayYoutubeVideo = (WebView) rootView.findViewById(R.id.videoView);
    displayYoutubeVideo.setWebViewClient(new WebViewClient() {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            return false;
        }
    });
    WebSettings webSettings = displayYoutubeVideo.getSettings();
    webSettings.setJavaScriptEnabled(true);
    displayYoutubeVideo.loadData(frameVideo, "text/html", "utf-8");
  return rootView;
    }

在layout.xml内：

 <WebView android:id="@+id/videoView"
            android:layout_height="wrap_content"
            android:layout_width="match_parent"
            android:layout_marginTop="-45dp"
            android:layout_marginLeft="-5dp"/>

这将很好地工作。
