视频视图在android中旋转90度

Question

我想将视频旋转 90 度。

当前我旋转布局，但视频无法播放。 xml

<LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="horizontal"
        android:rotation="90" >

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

java

videoView = (VideoView) findViewById(R.id.videoView);

          final Uri videoUri = Uri.parse(
               Environment.getExternalStorageDirectory().getAbsolutePath()+"/UnoPlayList/restaurant_menu_pro_mkv.mkv");

       videoView.setVideoPath(Environment.getExternalStorageDirectory().getAbsolutePath()+"/UnoPlayList/restaurant_menu_pro_mkv.mkv");
       //videoView.setRotation(180);
    //  videoView.setVideoURI(videoUri);
      videoView.start();

有没有办法旋转视频。

Answer 1

使用camera.setDisplayOrientation() 和recorder.setOrientationHint() 方法在捕捉视频的同时旋转视频。

    camera = Camera.open();
    //Set preview with a 90° ortientation
    camera.setDisplayOrientation(90);
    camera.unlock();

    recorder = new recorder();
    recorder.setCamera(camera);
    recorder.setAudioSource(recorder.AudioSource.MIC);
    recorder.setVideoSource(recorder.VideoSource.CAMERA);
    recorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_720P));
    recorder.setPreviewDisplay(mPreview.getHolder().getSurface());
    recorder.setOutputFile(getOutputMediaFile(MEDIA_TYPE_VIDEO).toString());
    
    //Rotate video by 90 degree
    recorder.setOrientationHint(90);

你只是为视频视图设置旋转而已

          videoView.setRotation(90f);

          (or)


<VideoView
    android:id="@+id/videoView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:rotation="90" />
