从Android的前摄像头录制视频时颠倒淡化 [英] Video plays upside down when recorded from Front Camera in Android
问题描述
我在做Android的视频摄像头应用程序。它应该有背部和前置摄像头记录的能力。我与后置摄像头完成，一切都很好。但是，当我有前置摄像头录制，视频播放倒挂。我必须发挥记录在我的应用程序本身的视频。我使用VideoView，如何设置方向，或使其正常播放？在默认媒体播放器还打倒挂播放时视频。试图发送视频到iPhone和检查，但仍然发挥着倒挂。我已经向setOrientationHint但MediaRecorder无解的。
我的所有code是类似于<一个href=\"https://github.com/marakana/VideoCaptureDemo/tree/master/src/com/marakana/android/videocapturedemo\"相对=nofollow>中，我已经做了定制agargenta的视频捕捉演示。
问题似乎很奇怪，我感到震惊。

}
}
this.mediaRecorder.setOutputFile（this.initFile（）getAbsolutePath（））;
this.mediaRecorder.set previewDisplay（M preview.getHolder（）getSurface（））; 尝试{
this.mediaRecorder prepare（）。 //开始实际拍摄
//抛出IllegalStateException异常如果不是prepared

}赶上（例外五）{
Toast.makeText（这一点，不能录，Toast.LENGTH_SHORT）.show（）;
e.printStackTrace（）;
this.releaseMediaRecorder（）;
}
这条线将专门旋转视频180度：
旋转=（cameraInfo.orientation - 180 + 360）％360;
除非你有这样做的，我不是看到一个原因，这就是为什么你的视频是上下颠倒。
I am doing android Video Camera Application. It should have capability of recording with back and front camera. I am done with back camera and everything is fine. But when I record with front camera, video plays upside down. I have to play the videos recorded in my application itself. I am using VideoView, How to set orientation or make it play correctly?. Video when played in default media player also playing upside down. Tried sending the video to iPhone and checked but still it plays upside down. I have setOrientationHint to MediaRecorder but no solution.
All My Code is similar to agargenta's Video Capture Demo in which I have done customization.
Issues seems to be strange and I am struck.
this.mediaRecorder = new MediaRecorder();
this.mediaRecorder.setCamera(this.mCamera);
this.mediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
this.mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
if (Build.VERSION.SDK_INT <= 10) {
CamcorderProfile camcorderProfile = CamcorderProfile
.get(CamcorderProfile.QUALITY_HIGH);
camcorderProfile.videoFrameWidth = 320;
camcorderProfile.videoFrameHeight = 480;
// camcorderProfile.videoFrameRate = 15;
camcorderProfile.videoCodec = MediaRecorder.VideoEncoder.H264;
// camcorderProfile.audioCodec = MediaRecorder.AudioEncoder.DEFAULT;
camcorderProfile.fileFormat = MediaRecorder.OutputFormat.MPEG_4;
this.mediaRecorder.setProfile(camcorderProfile);
mediaRecorder.setOrientationHint(90);
} else {
if (tgbSwitchCamera.isChecked()) {
mediaRecorder
.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
// mediaRecorder.setVideoSize(320, 480);
mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
CameraInfo cameraInfo = new CameraInfo();
Camera.getCameraInfo(CameraInfo.CAMERA_FACING_FRONT, cameraInfo);
rotation = (cameraInfo.orientation - 180 + 360) % 360;
mediaRecorder.setOrientationHint(rotation);
} else {
CamcorderProfile camcorderProfile = CamcorderProfile
.get(CamcorderProfile.QUALITY_LOW);
camcorderProfile.videoFrameWidth = 640;
camcorderProfile.videoFrameHeight = 480;
camcorderProfile.videoCodec = MediaRecorder.VideoEncoder.H264;
// camcorderProfile.audioCodec =
// MediaRecorder.AudioEncoder.DEFAULT;
camcorderProfile.fileFormat = MediaRecorder.OutputFormat.MPEG_4;
this.mediaRecorder.setProfile(camcorderProfile);
mediaRecorder.setOrientationHint(90);
}
}
this.mediaRecorder.setOutputFile(this.initFile().getAbsolutePath());
this.mediaRecorder.setPreviewDisplay(mPreview.getHolder().getSurface());
try {
this.mediaRecorder.prepare();
// start the actual recording
// throws IllegalStateException if not prepared
Handler h = new Handler();
h.postDelayed(new Runnable() {
@Override
public void run() {
this.mediaRecorder.start();
pgv.setStart(true);
pgv.invalidate();
CountDownTimer cdt = new CountDownTimer(5000, 1000) {
@Override
public void onTick(long millisUntilFinished) {
}
@Override
public void onFinish() {
if (isRecording) {
handler.removeMessages(STOP);
stopRecording();
}
}
};
cdt.start();
}
}, 1000);
// enable the stop button by indicating that we are recording
} catch (Exception e) {
Toast.makeText(this, "cannot record", Toast.LENGTH_SHORT).show();
e.printStackTrace();
this.releaseMediaRecorder();
}
This line will specifically rotate the video 180 degrees:
rotation = (cameraInfo.orientation - 180 + 360) % 360;
Unless you have a reason for doing this that I'm not seeing, that's why your video is upside-down.
