    mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
    mMediaRecorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH));
    mVideoFile = new File(getOutputMediaFile().toString());
    mMediaRecorder.setOutputFile(mVideoFile.getAbsolutePath());
    mMediaRecorder.setPreviewDisplay(mPreview.getHolder().getSurface());
    mMediaRecorder.setOrientationHint(270);
    mMediaRecorder.setMaxDuration(10000);
    mMediaRecorder.setOnInfoListener(this);
    try {
        mMediaRecorder.prepare();
    } catch (IllegalStateException e) {
        Log.d("CAMERA", "IllegalStateException preparing MediaRecorder: " + e.getMessage());
        releaseMediaRecorder();
        return false;
    } catch (IOException e) {
        Log.d("CAMERA", "IOException preparing MediaRecorder: " + e.getMessage());
        releaseMediaRecorder();
        return false;
    }
    return true;
}
if (prepareVideoRecorder()) {
    // Camera is available and unlocked, MediaRecorder is prepared,
    // now you can start recording
    mMediaRecorder.start();
}

Based on spitzanator's answer:

  1. Make sure your permissions are correct:

<uses-feature android:name="android.hardware.camera.front" />

  1. Apparently this line of code does not work with the front camera:

mMediaRecorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH));

spitzanator also says: That signature for CamcorderProfile.get() defaults to a profile for the back-facing camera:

Returns the camcorder profile for the first back-facing camera on the device at the given quality level. If the device has no back-facing camera, this returns null.

The ideal solution can be found here.

Side note: Due to low reputation I wasn't able to make a comment rather than posting an answer, so all the credits goes for spitzanator.
