Gets a frame at the given render time.
GetFrameAt ( int index ) : FFmpegMediaFrame

Gets the frame at the given index.
GetFrames ( decimal renderTime, decimal duration ) : List

Gets a maximum duration of frames at the given starting renderTime
GetFrames ( decimal renderTime, int frameCount ) : List

Gets a maximum of frameCount frames at the given starting renderTime
IndexOf ( FFmpegMediaFrame frame ) : int

Gets the index of the frame. Returns -1 for not found.
IndexOf ( decimal renderTime, bool checkBounds ) : int

Gets the index of the frame. Returns -1 if not found.
RemoveFirst ( ) : void

Removes the first frame and releases it.
RemoveLast ( ) : void

Removes the last frame and releases it.
Replace ( FFmpegMediaFrameCache newFrames ) : void

Replaces the internally-held frames with the specified new frames.
