Question

有很多控件可以在日食中播放youtube视频，例如WebView，YouTubePlayerView，VideoView等。

我怀疑是否可以使用媒体播放器播放它？发现，具有.mp4扩展名的网址可以使用媒体播放器播放。但是当尝试使用youtube视频网址时，它会显示错误Start Called in state 0。

if(isYTFlag){ //if youtube url

            mediaPlayer.setDataSource(videoURL);
        }
        else{ //local mp4

            afd = this.getResources().openRawResourceFd(Integer.parseInt(videoURL));
            mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getDeclaredLength());
        }

请帮助验证

这是另一个工作代码

MainActivity.java

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

VideoView videoView =(VideoView)findViewById(R.id.videoView);
MediaController mediaController= new MediaController(this);
mediaController.setAnchorView(videoView);
Uri uri=Uri.parse("rtsp://r2---sn-a5m7zu76.c.youtube.com/
Ck0LENy73wIaRAnTmlo5oUgpQhMYESARFEgGUg5yZWNvbW1lbmRhdGlvbnIhAWL2kyn64K6aQtkZVJdTxRoO88HsQjpE1a8d1GxQnGDmDA==/0/0/0/video.3gp");
videoView.setMediaController(mediaController);
videoView.setVideoURI(uri);
videoView.requestFocus();

videoView.start();}

activity_video_view.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"


android:layout_height="fill_parent">
   <VideoView android:id="@+id/videoView"
    android:layout_height="fill_parent"
    android:layout_width="fill_parent"/>
</LinearLayout>

你试过这个吗？

btnPlay.setOnClickListener(new OnClickListener() {public void onClick(View v) {
startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("https://www.youtube.com/watch?v=jHHn52KhBkQ")));
}}});

在此解决方案中，您可以直接将youtube视频网址传递给我们想要播放到媒体播放器中的Intent。

要播放视频，请尝试此链接Playing(Streaming) video with MediaPlayer

使用您的videoUrl而不是他们的3gp视频网址。

您可以轻松地使用媒体播放器播放视频，如下所示。 Player.java文件

        public class Player extends Activity implements SurfaceHolder.Callback,
                    OnPreparedListener {
                private MediaPlayer mediaPlayer;
                private SurfaceHolder vidHolder;
                private SurfaceView vidSurface;
                String vidAddress = "https://archive.org/download/ksnn_compilation_master_the_internet/ksnn_compilation_master_the_internet_512kb.mp4";
                String videoSrc = "http://bffmedia.com/bigbunny.mp4";
                String videoToPlay = "rtsp://v6.cache1.c.youtube.com/CjYLENy73wIaLQkDsLHya4-Z9hMYDSANFEIJbXYtZ29vZ2xlSARSBXdhdGNoYKX4k4uBjbOiUQw=/0/0/0/video.3gp";

                @Override
                protected void onCreate(Bundle savedInstanceState) {
                    // TODO Auto-generated method stub
                    super.onCreate(savedInstanceState);
                    setContentView(R.layout.mediaplayer);
                    vidSurface = (SurfaceView) findViewById(R.id.surfView);
                    vidHolder = vidSurface.getHolder();
                    vidHolder.addCallback(this);

                }

                @Override
                public void onPrepared(MediaPlayer mp) {
                    // TODO Auto-generated method stub
                    mediaPlayer.start();
                }

                @Override
                public void surfaceCreated(SurfaceHolder holder) {
                    // TODO Auto-generated method stub
                    try {
                        mediaPlayer = new MediaPlayer();
                        mediaPlayer.setDisplay(vidHolder);
                        mediaPlayer.setDataSource(videoToPlay);
                        mediaPlayer.prepare();
                        mediaPlayer.setOnPreparedListener(this);
                        mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }

                }

                @Override
                public void surfaceChanged(SurfaceHolder holder, int format, int width,
                        int height) {
                    // TODO Auto-generated method stub

                }

                @Override
                public void surfaceDestroyed(SurfaceHolder holder) {
                    // TODO Auto-generated method stub

                }

            }
