Embodiment Construction

[0014] The embodiment of the present invention provides a method that supports direct frame precise positioning of streaming media files. Through the embodiment of the present invention, the data in the streaming media file package is converted into a non-linear method, and each frame in the file package is accurately positioned. . This makes it possible to process, retrieve and edit streaming media files in the nonlinear video processing process, and then shortens the waiting time and saves resources when producing TV programs.

[0015] The current streaming media technology is very unfavorable to editors in the video field of TV stations. Therefore, we need to disassemble the data packet during the file import process, analyze each frame, and write it into an identifiable file. It is equivalent to creating a directory and then reading and writing.

[0016] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is des...

Abstract

The invention discloses a direct and accurate frame positioning method supporting stream media files. The method comprises the following steps of: reading a stream media file packet and recording frame data; judging the recorded frame data and saving the frame data into a corresponding secondary index; when the secondary index reaches a preset full state, saving the frame data into the secondary index in a corresponding primary index; and generating a header file. According to the embodiment of the invention, a received stream media packet is analyzed; data in the packet is divided for extracting effective information, and the extracted effective information is recorded in a companion file, therefore, accurate processing, rapid search and accurate editing of stream media files in nonlinear video processing can be realized, the editing time of a user can be greatly reduced, and the working efficiency can be improved remarkably.

Description

technical field [0001] The invention relates to the technical field of program production, in particular to a method for supporting direct frame precise positioning of streaming media files. 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. However, in the context of the current national policy of triple play, there are very high requirements for the development of the Internet, TV, and telecommunications. [0003] Streaming media is a continuous audio / video data stream transmitted and played in chronological order on the data network. As a new media transmission method, it is more and more widely used in the field of video and TV production. The streaming transmission method of streaming media can divide the entire A / V and 3D multimedia files into data packets containing basic block...
