Embodiments of the present application provide a stream media feature extraction method, a multi-modal content representation model establishment method, a stream media feature extraction device and an electronic device, relating to the technical field of artificial intelligence. The method extracts the content features of video clips in stream media through a pre-established multi-modal content representation model.
