Question

我正在使用带有媒体记录器的surfaceview录制视频，它正在录制但是显示角度是90度移位它不是实际的房间记录，即如果你用我的应用录制房间，显示器将90度移位，房间天花板将在左侧，所以你的房间显示。任何人帮我解决这个问题，以直角视频录制。这是我的代码供您参考，请在这里查看我的编码
main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="horizontal"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   >
<SurfaceView
  android:id="@+id/videoview" 
  android:layout_height="480px" android:layout_width="248dp"/>
<Button
  android:id="@+id/mybutton"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:text="REC"
  android:textSize="12dp"/> 
</RelativeLayout>`

这是我的清单文件

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".SurfaceAngleRecActivity"
                  android:label="@string/app_name">
            <intent-filter>

Answer 1

在Manifest中将您的活动方向更改为横向。

<application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".SurfaceAngleRecActivity" android:screenOrientation="landscape" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application>

Answer 2

private void initMediaRecorder()
           {
               mediaRecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
               mediaRecorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
               //File file=new File(Environment.getExternalStorageDirectory(), PlayPath);
               CamcorderProfile camcorderProfile_HQ =CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH);
               mediaRecorder.setProfile(camcorderProfile_HQ);
               mediaRecorder.setOutputFile("/sdcard/myvideo.mp4");
               **mediaRecorder.setOrientationHint(90);**
           }
