How to rotate a Video in WindowsPhone 8.1 Silverlight

Question

Hi,
Let me explain my problem.
I want to record video without shutter sound, so i choice CaptureSource  instead of
MediaCapture.
With MediaCapture i can set SetPreviewRotation(VideoRotation) to
change to rotate of video, the problem is with CaptureSource,
i can't do that.
So i looking for some way to rotate a video.
With library, maybe ffmpeg is the right way, but i can't use it with WP.
Anyone can tell me how to rotate a video, please ?

Since you didn't share any code, I hope this works for you. They key here is to rotate the VideoBrush.
//check if webcam is detected
if (captureSource.VideoCaptureDevice != null)
captureSource.Start();
//RotateTransform
RotateTransform aRotateTransform = new RotateTransform();
aRotateTransform.CenterX = 0.5;
aRotateTransform.CenterY = 0.5;
aRotateTransform.Angle = 90; //set this value to what you need
//create a videobrush
VideoBrush vBrush = new VideoBrush();
//set the rotate transform to VideoBrush relativetransform
vBrush.RelativeTransform = aRotateTransform;
//set it to us the capture source
vBrush.SetSource(captureSource);
//fill the rectangle with the video brush contents
vRect.Fill = vBrush;
Hope it works.
