Capture video in mp4 format using intent - Android

So I have been searching for the solution from past few days but it seems that I am unable to find any. At first it seems simple enough.
I have an app that uses default Android camera app to capture the video using intent. Video recording is working perfect but the file format is 3gp. I want to record the video in mp4 format but I do not want to implement my own mediarecorder etc to build my own video recording module.
I have also searched for available extra parameters I can pass into the intent for the file format but I couldn't.
Is there any extra parameter that I can use for selecting file format?
Thanks for all your help!

// Use this code to capture Mp4 video.

Camera recording with framelayout and surfaceview

Trying to record video without default camera of android. I found some sample code to fix my solution. Now in that camera previewing orientation in the framelayout is little weired. When I start the record with portrait the preview is landscape and vice-versa.
I tried with setting rotation for both surfaceview and framelayout. Then I tried with setting orientation and nothing worked for me.
My app is to save the recorded video of front facing camera and save it sd card. All are working fine except that orientation problem.
My code goes below,
Layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<RelativeLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<FrameLayout
android:id="#+id/videoview"
android:layout_width="200dp"
android:layout_height="200dp"/>
<Button
android:id="#+id/mybutton"
android:layout_width="100dp"
android:layout_height="50dp"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:text="REC"

This should fix your issue:
private static void setCameraDisplayOrientation(Context mContext, android.hardware.Camera.CameraInfo info) {
int rotation = ((MainActivity) mContext).getWindowManager().getDefaultDisplay()
.getRotation();
int degrees = 0;
switch (rotation) {
case Surface.ROTATION_0:
degrees = 0;
break;
case Surface.ROTATION_90:
degrees = 90;
break;
case Surface.ROTATION_180:
degrees = 180;
break;
case Surface.ROTATION_270:
degrees = 270;
break;
}
if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
previewRotation = (info.orientation + degrees) % 360;
previewRotation = (360 - previewRotation) % 360; // compensate the mirror
} else { // back-facing
previewRotation = (info.orientation - degrees + 360) % 360;
}
mCameraInstance.setDisplayOrientation(previewRotation);
}

Android Video Orientation changes on mediarecorder.Start()

This question is similar to posts here, here, here, here and here, but I'm stuck and have spent hours trying to figure it out.
I have a video camera preview (which now always shows in the correct orientation), but when I hit record (mediaRecorder.start();), the video orientation changes. I have tried using setOrientationHint, but it doesn't seem to make a difference (as marked in a comment in the code below).
It affects both my test devices (Galaxy and Xperia on Jelly Bean). What should I do to fix this please?
Here's my code:
XML
<RelativeLayout android:id="#+id/surface_camera"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerInParent="true"
android:layout_weight="1"
>
<RelativeLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<FrameLayout
android:id="#+id/videoview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
<Button
android:id="#+id/mybutton"
android:layout_width="100dp"
android:layout_height="50dp"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:text="REC"
android:textSize="12dp"/>

I had a similar problem, i used Rotating a Camera SurfaceView to portrait to set the orientation, i modified it to also set the result to a class variable and set the orientation for the media recorder.

GetCameraDisplayOrientation returns always 0

I'm trying to record a video in the correct orientation in Android. I've built my Activity, it works correctly, the only thing is that the saved video after being recorded is rotated. The preview of the camera works correctly so I can't understand why. To fix the rotation I use this code (the method I've found on Google Developers):
mMediaRecorder.setOrientationHint(getCameraDisplayOrientation());
private int getCameraDisplayOrientation()
{
android.hardware.Camera.CameraInfo info = new android.hardware.Camera.CameraInfo();
android.hardware.Camera.getCameraInfo(CameraInfo.CAMERA_FACING_BACK,
info);
int rotation = getWindowManager().getDefaultDisplay().getRotation();
int degrees = 0;
switch (rotation)
{
case Surface.ROTATION_0:
degrees = 0;
break;
case Surface.ROTATION_90:
degrees = 90;
break;
case Surface.ROTATION_180:
degrees = 180;
break;
case Surface.ROTATION_270:
degrees = 270;
break;
}
int result;
if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT)
{
result = (info.orientation + degrees) % 360;
result = (360 - result) % 360; // compensate the mirror
} else
{ // back-facing
result = (info.orientation - degrees + 360) % 360;
}
return result;
The Activity is defined in the manifest like that:
<activity android:name="pages.CameraPage"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"
android:screenOrientation="landscape"
>
</activity>
The problem is that getCameraDisplayOrientation always returns 0 degrees, no matter how I orient the screen.
I call the method just before the record starts so if I would be able to get the rotation of the screen with respect to the default landscape I'd be ok.
Thanks for your help!

Finally I was able to build successfully my own camera app without any orientation problem. The key was looking at the surfaceView for the rotation. I think it might help someone to have all the code posted here, just copy it and launch the Activity!

The Activity has been tested from Android 2.3.6 to 4.3. If you find any problem or have any suggestion please let me know!

If your issue is associated with your rotation variable, you may consider looking at this link. The main difference to pull away from that link is a WindowManager object is created and then used to get the rotation. This seemingly small difference has been the difference maker between a piece of my code working and not working.
You can simply say Camera.CameraInfo info = new Camera.CameraInfo(); and Camera.getCameraInfo(...);.
I am curious as to why you are specifying CameraInfo.CAMERA_FACING_BACK in android.hardware.Camera.getCameraInfo(CameraInfo.CAMERA_FACING_BACK, info); I feel like you could just call info.facing to get the int instead.
I hope between the link and my suggestions/inquiries that something sparks the correct answer!

Video recorded with Android MediaRecorder is corrupted on Samsung Galaxy S2

Good day! I'm learning how to record video with MediaRecorder but recorded video is corrupted when I play it. See this screenshot: http://www.4shared.com/photo/QtmJCHRi/corrupted-video.html. Picture marked with red rectangle in the left upper corner is what camera can see. But it is so small, it's repeating and there is many green areas. Please advise what am I doing wrong. HW is Samsung Galaxy S2 (GT-I9100, Android 2.3.5). I tried to follow this tutorial: http://developer.android.com/guide/topics/media/camera.html#saving-media
Thank you in advance!

I read about it somewhere (I think it was in SO). The problem is that apparently, the Samsung Galaxy doesn't support recording in HIGH QUALITY (CamcorderProfile.QUALITY_HIGH).
Try with CamcorderProfile.QUALITY_LOW. to see if it works.
EDIT: I found the question with the same issue here
