我試圖讓視頻播放爲背景。但我只能把它拿到屏幕的一半。所以,我需要將視頻延伸至16:9並將其旋轉90度以使其全屏。如何使視頻內的視頻旋轉90度並使其成爲全屏
我現在正在一個測試項目中工作。
MainActivity
public class MainActivity extends AppCompatActivity implements GestureOverlayView.OnGesturePerformedListener{
GestureLibrary gestureLib;
VideoView vvRick;
private Button btnTest;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
gestureLib = GestureLibraries.fromRawResource(this, R.raw.gestures);
if (!gestureLib.load()) {
finish();
}
GestureOverlayView gOverlay =
(GestureOverlayView) findViewById(R.id.gOverlay);
gOverlay.addOnGesturePerformedListener(this);
vvRick = (VideoView)findViewById(R.id.vvRick);
btnTest = (Button)findViewById(R.id.btnTest);
btnTest.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(), "Workss!!",
Toast.LENGTH_LONG).show();
}
});
}
public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) {
ArrayList<Prediction> predictions = gestureLib.recognize(gesture);
if (predictions.size() > 0 && predictions.get(0).score > 3.0) {
String result = predictions.get(0).name;
if ("turn".equalsIgnoreCase(result)) {
Toast.makeText(this, "Reverse", Toast.LENGTH_LONG).show();
} else if ("easteregg".equalsIgnoreCase(result)) {
Toast.makeText(this, "EasterEgg", Toast.LENGTH_LONG).show();
vvRick.setVideoURI(Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.rickroll));
vvRick.start();
} else{
Toast.makeText(this, "FOUT", Toast.LENGTH_LONG).show();
}
}
}
}

最簡單的將是旋轉'VideoView'。否則,你需要提取每個幀旋轉,然後將它們放在一起,以創建一個視頻等 –
我試過,但現在它並沒有顯示。儘管我可以聽到視頻的聲音。 –
