使用SurfaceView和媒體錄制器的Android中的視頻錄制器應用程序：錄制視頻時，它向左顯示90度彎曲

Question

使用SurfaceView進行視頻錄制，一切都很好，但是錄制時視頻向左旋轉了90度。

setContentView(R.layout.activity_video_capture);

SurfaceView cameraView = (SurfaceView) findViewById(R.id.videoview);
surfaceHolder = cameraView.getHolder();
surfaceHolder.addCallback(this);
surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

Answer 1

嘗試這個：

camera = Camera.open(Camera.CameraInfo.CAMERA_FACING_BACK);
camera.setDisplayOrientation(90);
camera.unlock();
mediaRecorder = new MediaRecorder();
mediaRecorder.setCamera(camera);
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
mediaRecorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
CamcorderProfile camcorderProfile_HQ = CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH);
mediaRecorder.setProfile(camcorderProfile_HQ);
mediaRecorder.setOutputFile(getOutputMediaFile(2).toString());
mediaRecorder.setMaxDuration(60000); // Set max duration 60 sec.
mediaRecorder.setMaxFileSize(5000000); // Set max file size 5M
