Ich verwende den Media Player, um ein Video zu streamen. Er spielt nur den Ton ab, aber nicht das Video. Kann mir jemand helfen? Mein Code ist unten.
public class VideoViewApplication extends Application {
@Override
public void onCreate() {
}
@Override
public void onTerminate() {
}
}
public class VideoViewDemo extends Activity implements
OnErrorListener,OnBufferingUpdateListener, OnCompletionListener,
MediaPlayer.OnPreparedListener, SurfaceHolder.Callback {
private static final String TAG = "VideoViewDemo";
private MediaPlayer mp;
private EditText mPath;
private SurfaceHolder holder;
private ImageButton mPlay;
private ImageButton mPause;
private ImageButton mReset;
private ImageButton mStop;
private String current;
private SurfaceView mPreview;
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
mPreview = (SurfaceView) findViewById(R.id.surface);
mPath = (EditText) findViewById(R.id.path);
mPath.setText("rtsp://video2.americafree.tv/AFTVHorrorH26496.sdp");
mPlay = (ImageButton) findViewById(R.id.play);
mPause = (ImageButton) findViewById(R.id.pause);
mReset = (ImageButton) findViewById(R.id.reset);
mStop = (ImageButton) findViewById(R.id.stop);
mPlay.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
playVideo();
}
});
mPause.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
if (mp != null) {
mp.pause();
}
}
});
mReset.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
if (mp != null) {
mp.seekTo(0);
}
}
});
mStop.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
if (mp != null) {
current = null;
mp.stop();
mp.release();
}
}
});
// getWindow().setFormat(PixelFormat.TRANSPARENT);
holder = mPreview.getHolder();
holder.addCallback(this);
holder.setFixedSize(100, 100);
runOnUiThread(new Runnable(){
public void run(){
playVideo();
}
});
}
private void playVideo() {
try {
final String path = mPath.getText().toString();
Log.v(TAG, "path: " + path);
if (path.equals(current) && mp != null) {
mp.start();
return;
}
current = path;
mp = new MediaPlayer();
mp.setOnErrorListener(this);

mp.setDisplay(mPreview.getHolder());
mp.setDataSource(path);
mp.prepare();
Log.v(TAG, "Duration: ===>" + mp.getDuration());
mp.start();
} catch (Exception e) {
Log.e(TAG, "error: "+ e.getMessage(), e);
if (mp != null) {
mp.stop();
mp.release();
}
}
}
