This moves the video loading logic into 2 classes:
VideoMetadataandVideoLoader.VideoMetadatais powered byffprobeand gets metadata like frame width and frame height.VideoLoaderbasically just returns an iterators for all frames in the video.I also added a bit of type checking for
ffmpeg_readerand used awithblock for resource safety.
