MediaRecorder样本作品在Landscape模式，并使其工作在portrait模式以及您需要添加以下代码精确序列!
这是代码：-
添加这个用于portrait支持mCamera
mCamera.setDisplayOrientation(90);
并支持Audio/Video编码器和OutputFormat添加这个
mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
所以下面是你的完整方法prepareVideoRecorder
private boolean prepareVideoRecorder(){
// BEGIN_INCLUDE (configure_preview)
mCamera = CameraHelper.getDefaultCameraInstance();
mCamera.setDisplayOrientation(90);
// We need to make sure that our preview and recording video size are supported by the
// camera. Query camera to find all the sizes and choose the optimal size given the
try {
// Requires API level 11+, For backward compatibility use {@link setPreviewDisplay}
// with {@link SurfaceView}
mCamera.setPreviewTexture(mPreview.getSurfaceTexture());
} catch (IOException e) {
Log.e(TAG, "Surface texture is unavailable or unsuitable" + e.getMessage());
return false;
}
// END_INCLUDE (configure_preview)
// BEGIN_INCLUDE (configure_media_recorder)
mMediaRecorder = new MediaRecorder();
// Step 1: Unlock and set camera to MediaRecorder
mCamera.unlock();
mMediaRecorder.setCamera(mCamera);
// Step 2: Set sources
mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mMediaRecorder.setOrientationHint(90);
// Step 3: Set a CamcorderProfile (requires API Level 8 or higher)
mMediaRecorder.setOutputFile(CameraHelper.getOutputMediaFile(
CameraHelper.MEDIA_TYPE_VIDEO).toString());
//
//mMediaRecorder.setPreviewDisplay(SufaceView);
// Step 4: Set output file
// END_INCLUDE (configure_media_recorder)
// Step 5: Prepare configured MediaRecorder
try {
mMediaRecorder.prepare();
} catch (IllegalStateException e) {
Log.d(TAG, "IllegalStateException preparing MediaRecorder: " + e.getMessage());
releaseMediaRecorder();
return false;
} catch (IOException e) {
Log.d(TAG, "IOException preparing MediaRecorder: " + e.getMessage());
releaseMediaRecorder();
return false;
}
return true;
}
最后你可以删除screenOrientation从清单
android:screenOrientation="landscape"
上面的代码适用于orientation but Camera显示始终会是90 degree所以你需要通过正确处理你的方向来做出改变。
