MediaCapture Windows Phone and Windows 8.1 App handle orientation working on all scenarios - windows-phone-8.1

Question

I have tried all the solutions over the network but no one of these cover all the rotation and orientation cases.
Is there a complete and better solution or documentation to get me able to use mediacapture object well?

If you look at the CameraStarterKit sample from the Microsoft GitHub repository, you'll get a much better idea for how to handle rotation of the camera. It targets Windows 10, but a lot of the code should be portable back to 8.1.
Mainly, it comes down to this:
// Receive notifications about rotation of the device and UI and apply any necessary rotation to the preview stream and UI controls
private readonly DisplayInformation _displayInformation = DisplayInformation.GetForCurrentView();
private readonly SimpleOrientationSensor _orientationSensor = SimpleOrientationSensor.GetDefault();
private SimpleOrientation _deviceOrientation = SimpleOrientation.NotRotated;
private DisplayOrientations _displayOrientation = DisplayOrientations.Portrait;
// Rotation metadata to apply to the preview stream and recorded videos (MF_MT_VIDEO_ROTATION)
// Reference: http://msdn.microsoft.com/en-us/library/windows/apps/xaml/hh868174.aspx
private static readonly Guid RotationKey = new Guid("C380465D-2271-428C-9B83-ECEA3B4A85C1");
/// <summary>
/// Gets the current orientation of the UI in relation to the device (when AutoRotationPreferences cannot be honored) and applies a corrective rotation to the preview
/// </summary>
private async Task SetPreviewRotationAsync()
{
// Only need to update the orientation if the camera is mounted on the device
if (_externalCamera) return;
// Calculate which way and how far to rotate the preview
int rotationDegrees = ConvertDisplayOrientationToDegrees(_displayOrientation);
// The rotation direction needs to be inverted if the preview is being mirrored
if (_mirroringPreview)
{
rotationDegrees = (360 - rotationDegrees) % 360;
}
// Add rotation metadata to the preview stream to make sure the aspect ratio / dimensions match when rendering and getting preview frames
var props = _mediaCapture.VideoDeviceController.GetMediaStreamProperties(MediaStreamType.VideoPreview);
props.Properties.Add(RotationKey, rotationDegrees);
await _mediaCapture.SetEncodingPropertiesAsync(MediaStreamType.VideoPreview, props, null);
}
/// <summary>
/// Registers event handlers for hardware buttons and orientation sensors, and performs an initial update of the UI rotation
/// </summary>
private void RegisterEventHandlers()
{
// If there is an orientation sensor present on the device, register for notifications
if (_orientationSensor != null)
{
_orientationSensor.OrientationChanged += OrientationSensor_OrientationChanged;
// Update orientation of buttons with the current orientation
UpdateButtonOrientation();
}
_displayInformation.OrientationChanged += DisplayInformation_OrientationChanged;
}
But this is just part of the code. You should have a look at the full file (if not the full sample) to get a better understanding of how it works.
