The invention discloses a mass data-based distributed video processing system, which comprises the following steps: (1) reading, partitioning and packaging of a video, firstly, obtaining a video file in a corresponding path from an HDFS distributed file system, carrying out reading and partitioning on the video file, and packaging the partitioned video segment data into an object for carrying out a transmission on a video envelop; (2) video analysis algorithm packaging, namely adopting a video analysis algorithm for finishing analysis processing on the video segment data, and carrying out an interaction on the video analysis algorithm and a Hadoop platform through a JNI interface; and (3) result integration and storage, calling packaged video analysis algorithm on each node to finish video analysis processing by the Hadoop platform, and integrating the video segment data into an intact video. According to the mass data-based distributed video processing system, the problems that traditional concentrated video processing is inadequate in storage capacity and processing capacity cannot be expanded are solved; and distributed processing and analysis of massive videos are achieved through expansion of a data structure and related interfaces of a MapReduce computing framework in the Hadoop platform.
