To facilitate the creation of video bookmarks or chapter links for a long movie, the MPMoviePlayerController class defines methods for generating thumbnail images at specific times within a movie. You can request a single thumbnail image using the thumbnailImageAtTime:timeOption: method or request multiple thumbnail images using the requestThumbnailImagesAtTimes:timeOption: method.
