How to compress/resize and display video in the view

Question

I am displaying images and video as the thumbnail in the view page. Whenever a user uploads image or video I am saving URL into DB and files into the folder. While displaying I am resizing image size on the server side to reduce the page load time. I am able to compress the images and but not the videos. How to resize or compress the video same as the image. At present videos are not displaying because using the same logic to retrieve both image and videos.
