MRML node for representing a single compressed video frame that can be decoded to an image representation In this context, a frame is considered to be a compressed image that may require additional frames to decode to an image, and an image is the uncompressed pixel based representation. A video codec can be used to decode and encode between frame and image representations. More...

Detailed Description

MRML node for representing a single compressed video frame that can be decoded to an image representation In this context, a frame is considered to be a compressed image that may require additional frames to decode to an image, and an image is the uncompressed pixel based representation. A video codec can be used to decode and encode between frame and image representations.
