Center crop a playing video

I have an app which uses video and images in posts. The video and images are fit in a fixed rectangular frame taking the full width of the device and height calculated on the ratio to width. The video if smaller than the rectangular frame stretches and the video larger in height than the rectangular frame is shrunk. I want someone to fix it such that if too large we just center crop and if smaller we zoom. in some places of the code, I see VideoView and scalableVideoView implemented.
