Mass video file storage system based on cloud computation, analysis method and system thereof

The invention relates to the video monitoring field, and discloses a mass video file storage system based on cloud computation, a mass video file analysis method and a mass video file system. Slicing is performed accurately, so that decoding for video data analysis is complete and effective. According to the mass video file storage system provided by the invention, the method comprises the following steps: a client inquires management information of a video file, and slices the video file according to the management information and generates slice information, wherein a slice comprises at least one data block, each data block comprises at least one video frame sequence, each video frame sequence in each data block is complete; the client uploads the slice information to a main node and submits assignments to the main node; the main node decomposes the assignments and distributes tasks and slice information to task nodes; each task node executes the distributed task, acquires and analyzes the data block; each task node acquires metadata obtained by analysis, concludes and outputs.
