-// This file contains two classes, VideoRecorder and FileVideoCapturer.
-// VideoRecorder records the captured frames into a file. The file stores a
-// sequence of captured frames; each frame has a header defined in struct
-// CapturedFrame, followed by the frame data.
-//
-// FileVideoCapturer, a subclass of VideoCapturer, is a simulated video capturer
-// that periodically reads images from a previously recorded file.
