I found questions like this. Some say that is possible, but the solutions have not worked for me and others say that is not possible.
I have this code for record mp4:
import java.io.IOException;
import android.app.Activity;
import android.content.pm.ActivityInfo;
import android.media.CamcorderProfile;
import android.media.MediaRecorder;
import android.os.Bundle;
import android.os.Environment;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import android.view.View;
import android.view.View.OnClickListener;
public class MainActivity extends Activity implements OnClickListener, SurfaceHolder.Callback {
MediaRecorder recorder;
SurfaceHolder holder;
boolean recording = false;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
recorder = new MediaRecorder();
initRecorder();
setContentView(R.layout.activity_main);
SurfaceView cameraView = (SurfaceView) findViewById(R.id.surfaceView1);
holder = cameraView.getHolder();
holder.addCallback(this);
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
cameraView.setClickable(true);
cameraView.setOnClickListener(this);
}
private void initRecorder() {
recorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
CamcorderProfile cpHigh = CamcorderProfile
.get(CamcorderProfile.QUALITY_HIGH);
recorder.setProfile(cpHigh);
recorder.setOutputFile(Environment.getExternalStorageDirectory().getPath() + "/video.mp4");
recorder.setMaxDuration(5 * 1000); // 50 seconds
recorder.setMaxFileSize(5 * 1000000); // Approximately 5 megabytes
}
private void prepareRecorder() {
recorder.setPreviewDisplay(holder.getSurface());
try {
recorder.prepare();
} catch (IllegalStateException e) {
e.printStackTrace();
finish();
} catch (IOException e) {
e.printStackTrace();
finish();
}
}
public void onClick(View v) {
if (recording) {
recorder.stop();
recording = false;
// Let's initRecorder so we can record again
initRecorder();
prepareRecorder();
} else {
recording = true;
recorder.start();
}
}
public void surfaceCreated(SurfaceHolder holder) {
prepareRecorder();
}
public void surfaceChanged(SurfaceHolder holder, int format, int width,
int height) {
}
public void surfaceDestroyed(SurfaceHolder holder) {
if (recording) {
recorder.stop();
recording = false;
}
recorder.release();
finish();
}
}
And this other for get frames in real time:

import java.util.Iterator;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mVideoCaptureView = (SurfaceView) findViewById(R.id.surfaceView1);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
SurfaceHolder videoCaptureViewHolder = mVideoCaptureView.getHolder();
videoCaptureViewHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
videoCaptureViewHolder.addCallback(new Callback() {
public void surfaceDestroyed(SurfaceHolder holder) {
stopVideo();
}
public void surfaceCreated(SurfaceHolder holder) {
startVideo();
}
public void surfaceChanged(SurfaceHolder holder, int format,
int width, int height) {
}
});
}
private void startVideo() {
//Open camera
SurfaceHolder videoCaptureViewHolder = null;
try {
mCamera = Camera.open();
} catch (RuntimeException e) {
Log.e("CameraTest", "Camera Open failed");
return;
}
mCamera.setErrorCallback(new ErrorCallback() {
public void onError(int error, Camera camera) {
}
});
//Get params
Camera.Parameters parameters = mCamera.getParameters();
//Get Frame rate
int[] minFrameRate = {90000,90000};
List<int[]> supportedPreviewFps=parameters.getSupportedPreviewFpsRange();

while(supportedPreviewFpsIterator.hasNext()){
int[] tmpRate=supportedPreviewFpsIterator.next();
if(tmpRate[0]<minFrameRate[0])
{
minFrameRate[0] = tmpRate[0];
minFrameRate[1] = tmpRate[1];
}
}
//Set frame rate
parameters.setPreviewFpsRange(minFrameRate[0],minFrameRate[1]);
Log.i("Info", "Frame rate set to: " + minFrameRate[0] + ','+ minFrameRate[1]);
//Get image size
List<Size> supportedPreviewSizes=parameters.getSupportedPreviewSizes();

while(supportedPreviewSizesIterator.hasNext()){

Log.v("CameraTest","supportedPreviewSize.width = "+tmpSize.width+"supportedPreviewSize.height = "+tmpSize.height);
}
//Set params
mCamera.setParameters(parameters);
if ( mVideoCaptureView!=null)
videoCaptureViewHolder = mVideoCaptureView.getHolder();
try
{
mCamera.setPreviewDisplay(videoCaptureViewHolder);
} catch (Throwable t)
{
Log.e("Error","mCamera.setPreviewDisplay(videoCaptureViewHolder) fail");
}
//Start camera
Size previewSize=mCamera.getParameters().getPreviewSize();
int dataBufferSize=(int)(previewSize.height*previewSize.width*
(ImageFormat.getBitsPerPixel(mCamera.getParameters().getPreviewFormat())/8.0));
mCamera.addCallbackBuffer(new byte[dataBufferSize]);
mCamera.addCallbackBuffer(new byte[dataBufferSize]);
mCamera.addCallbackBuffer(new byte[dataBufferSize]);
mCamera.setPreviewCallbackWithBuffer(new Camera.PreviewCallback() {
public synchronized void onPreviewFrame(byte[] data, Camera camera) {
try
{
camera.addCallbackBuffer(data);
}catch (Exception e) {
Log.e("CameraTest", "addCallbackBuffer error");
}
}
});
try {
mCamera.startPreview();
} catch (Throwable e) {
mCamera.release();
mCamera = null;
return;
}
}
private void stopVideo() {
Log.i("StopVideo","OK");
if(null==mCamera)
return;
try {
mCamera.stopPreview();
mCamera.setPreviewDisplay(null);
mCamera.setPreviewCallbackWithBuffer(null);
mCamera.release();
} catch (IOException e) {
e.printStackTrace();
return;
}
mCamera = null;
}
public void finish(){
stopVideo();
super.finish();
}
@Override
public void onBackPressed() {
stopVideo();
super.onBackPressed();
};
}
This last code have a funcion "onPreviewFrame" that get frames in real time.
How I can include this function to the first piece of code?
I've tried to make using the Camera object, but if Camara is open and starts recording mp4 fails because it can not do both at once
