Abstract

The invention discloses a method for quickly generating an index, which comprises the following steps: establishing a memory pool BlockAllocator which comprises a plurality of DataBlocks; reading data of a streaming media file into the current DataBlock by a data reading scheduling thread; analyzing the data of the streaming media file in the current DataBlock by a data analyzing scheduling thread according to a streaming media data analyzing function, thereby generating IndexInfoData; and writing the IndexInfoData into an Index companion file by an Index companion file data writing thread. Various hardware resources of a computer are fully utilized, and reasonable and effective scheduling is realized, the efficiency of generating the streaming media Index companion file is optimized, the speed reaches the highest and the waiting time for importing the file by a user is reduced.

Description

technical field [0001] The invention relates to the field of streaming media editing, in particular to a method for quickly generating indexes. Background technique [0002] With the rapid development of multimedia video services, the storage medium of files is not limited to cassettes or optical discs, and streaming media suitable for network transmission has received more attention. Streaming Media (Streaming Media) refers to the media format played on the Internet in the form of streaming transmission. It is a continuous audio / video data stream in which data is transmitted and played in chronological order on the network. It is a new media transmission method. It is also more and more widely used in the field of video and TV program production. The streaming transmission method of streaming media can divide the entire A / V and 3D multimedia files into data packets containing basic block information through a special block method, and transmit them continuously and in real...
