Component

Components gather all the modules of the enc.

• video.py implements the class VideoEncoder which is used to compress a video i.e. one intra frame followed by zero or more inter frames. It contains one or more instances of FrameEncoder.

• frame.py implements the class FrameEncoder is used to compress a frame. To do so, it relies on one CoolChicEncoder.

• coolchic.py implements the class CoolChicEncoder, which is the main coding engine of the codec. It is composed of latent grids, an auto-regressive module, an upsampling and a synthesis.

• intercoding/ contains functions required to encode an intra frame such RAFT-based motion estimation, warping an image with an optical flow or finding a global translation between two frames.
