java中初始化MediaRecorder的实现方法
java中初始化MediaRecorder
实现代码：
privatebooleaninitializeVideo(){
Log.v(TAG,"initializeVideo");
if(mSurfaceHolder==null){
Log.v(TAG,"SurfaceHolderisnull");
returnfalse;
}
mMediaRecorderRecording=true;
if(mMediaRecorder==null)
mMediaRecorder=newMediaRecorder();
else
mMediaRecorder.reset();
if(mCamera!=null){
if(Integer.parseInt(Build.VERSION.SDK)>=8)
VideoCameraNew2.reconnect(mCamera);
mCamera.release();
mCamera=null;
}
if(useFront&&Integer.parseInt(Build.VERSION.SDK)>=5){
