iStretchMode - the stretch mode,  It will relate to PIPInitDisplayArea method.
 0  = The image is stretched to fit the target frame size in both dimensions, without preserving the aspect ratio.
 1  = The image is not resized. If the image is smaller than the target frame, the surrounding area is black. If the image is larger than the target frame, the image is cropped.
 2  = The image is resized to fit the target frame along one dimension, while preserving the aspect ratio. If the ratio of width to height    in the image does not match the ratio in the target frame, it creates a letterbox.
