Abstract
A method, system, and non-transitory computer readable storage medium having instructions for generating an event video sequence. The method comprises receiving input image frames encoded into a sequence of image frames arranged in groups of pictures, each group of pictures having a GOP structure. The method further comprises storing a pre-event sequence of image frames in a first-in-first-out buffer, said pre-event sequence having a first predetermined GOP structure, upon receiving an event notification, retrieving the pre-event sequence from the buffer, and generating the event video sequence by combining the pre-event sequence and a post-event sequence of image frames, said post-event sequence having a second GOP structure, which is different from said first GOP structure. The system may be included in a camera.
