 // VideoCaptureImpl represents a capture device in renderer process. It provides
 // interfaces for clients to Start/Stop capture. It also communicates to clients
 // when buffer is ready, state of capture device is changed.
 
 // VideoCaptureImpl is also a delegate of VideoCaptureMessageFilter which relays
 // operation of a capture device to the browser process and receives responses
 // from browser process.
 //
 // VideoCaptureImpl is an IO thread only object. See the comments in
 // video_capture_impl_manager.cc for the lifetime of this object.
 // All methods must be called on the IO thread.
 //
 // This is an internal class used by VideoCaptureImplManager only. Do not access
 // this directly.
