我正在做在Android中运行wowza示例链接。 Wowza示例链接是
here.，但在android中不起作用。
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);
}
}
}
实用工具
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;
}
}

最佳答案
我认为评论中没有余地...
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>
在以下代码中，将活动传递到一个单独的类中（这通常会在活动本身中发生，但我需要为较旧的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();
}
