我正在做在 android 中运行 wowza 示例链接。Wowza 示例链接在 这里。但它不适用于android。

我的代码在这里。

HelloAndroidActivity(MainActivity)

public class HelloAndroidActivity extends Activity implements OnClickListener {

private static String TAG = "androidEx2";

private Button buttonVideoSample;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.i(TAG, "onCreate");
    setContentView(R.layout.main);

    buttonVideoSample = (Button) findViewById(R.id.buttonVideoSample);
    buttonVideoSample.setOnClickListener(this);
}

public void onClick(View v) {
    if (v.getId() == R.id.buttonVideoSample) {
        String video_uri = "rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov";
        Intent intent = new Intent(this, VideoSample.class);
        intent.putExtra("video_path", video_uri);
        startActivity(intent);
    }
}
}

实用程序.java

public class Utils {
public static String durationInSecondsToString(int sec){
    int hours = sec / 3600; 
    int minutes = (sec / 60) - (hours * 60);
    int seconds = sec - (hours * 3600) - (minutes * 60) ;
    String formatted = String.format("%d:%02d:%02d", hours, minutes, seconds);
    return formatted;
}
}

我觉得评论区没有空间。。。

风景：

 <?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/hls_frame"
    android:background="#000000"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
<VideoView
    android:id="@+id/video_player"
    android:layout_height="match_parent"
    android:layout_width="match_parent"
    android:layout_gravity="center"
/>
    <include layout="@layout/player_bar" />
</FrameLayout>

在下面的代码中，活动被传递给一个单独的类（这通常发生在活动本身，但我需要为旧设备支持多个播放器）。感兴趣的方法：

public void loadPlayer() {
        _activity.setContentView(R.layout.hls_video_view);
        if (_activity.url == null) {
            Development.ExceptionMsg("Video Url is Null!");
            return;
        }
        VideoView view = (VideoView) _activity.findViewById(R.id.video_player);
        if (!_activity.isLive) {
            //MediaController for vod only
            MediaController controller = new MediaController(_activity);
            controller.setAnchorView(view);
            view.setMediaController(controller);
        }
        _activity.LogStreamStart();
        _activity.HideBuffering();
        view.setOnCompletionListener(this);
        view.setOnPreparedListener(this);
        view.setOnErrorListener(this);
        //this is important, and should perhaps be part of the interface
        view.setOnTouchListener(_activity);
        view.setVideoURI(Uri.parse(_activity.url));
        view.requestFocus();
        view.start();
    }
