I know your issue,

Video use Media Recorder from Camera, so you need rotate Media Recorder. use below codes should be fixed your issue.

/**
 * 
 * @param mMediaRecorder
 * @return
 */
public static MediaRecorder rotateBackVideo(MediaRecorder mMediaRecorder) {
    /**
     * Define Orientation of video in here,
     * if in portrait mode, use value = 90,
     * if in landscape mode, use value = 0
     */
    switch (CustomCamera.current_orientation) {
        case 0:
            mMediaRecorder.setOrientationHint(90);
            break;
        case 90:
            mMediaRecorder.setOrientationHint(180);
            break;
        case 180:
            mMediaRecorder.setOrientationHint(270);
            break;
        case 270:
            mMediaRecorder.setOrientationHint(0);
            break;
    }

    return mMediaRecorder;
}

Should add before prepare() method :

// Step 5: Set the preview output
    /**
     * Define Orientation of image in here,
     * if in portrait mode, use value = 90,
     * if in landscape mode, use value = 0
     */
    CustomCamera.mMediaRecorder = Utils.rotateBackVideo(CustomCamera.mMediaRecorder);
    CustomCamera.mMediaRecorder.setPreviewDisplay(mCameraPreview.getHolder().getSurface());

Thank you
