Abstract

The invention discloses a rapid video file playback method and system. The method comprises the following steps: receiving a playback time period input by a user; searching an index file set of video file sets corresponding to a revisit time period in a storage space, and copying the index file set into a playback index file; receiving play information input by the user, and searching an index file corresponding to initial play time in the play information in the playback index file; playing the corresponding index contents by utilizing the index file corresponding to the initial play time searched in the playback index file. According to the method and system disclosed by the invention, the index file set corresponding to the revisit time period in the storage space is copied in the pre-established playback index file after the revisit time period input by the user is received, the index file corresponding to the initial play time is searched in the playback index file and does not need to be searched in the storage space; therefore, the search time of the video index file is shortened, and the random playback efficiency at any time point is improved.

Description

technical field [0001] The invention relates to the technical field of big data retrieval, in particular to a method and system for fast playback of video files. Background technique [0002] In the actual application of intelligent transportation, it often occurs that the client repeatedly checks the information that is very valuable for a certain end. [0003] In the prior art, each playback check needs to be searched in the disk video file information table of the storage server, but the disk video file information table contains a large amount of data, and the query speed is slow, resulting in low efficiency of playing back video files. [0004] Therefore, how to quickly play back video files and improve playback efficiency is a problem to be solved. Contents of the invention [0005] In view of this, the object of the present invention is to provide a method and system for fast playback of video files, so as to quickly play back video files and improve playback effic...
