A distributed player flow control method and system

Abstract

The invention discloses a distributed player flow control method and system. The method comprises the following steps: connection is established between a player 1 control layer and a player 2 control layer; a player 1 sends a demultiplexing command Cmdprepare to a player 2; the player 2 constructs a demultiplexing module and a data sending module, and replies a Ready message to the player 1 control layer; the player 1 constructs a data receiving module, a decoding module and a rendering module, and notifies UI to carry out play; the player 2 starts the demultiplexing module, reads media file data from IO, carries out demultiplexing to separate original streaming data, and sends the original streaming data through the data sending module; and the player 1 starts the data receiving module, the decoding module and the rendering module, wherein the data receiving module receives the original streaming data and outputs the original streaming data to the decoding module, the decoding module decodes the output data, and outputs the decoded data to the rendering module, and the rendering module finishes rendering and outputs the rendered data. The method can improve media file playing speed and efficiency, thereby preventing obstruction of the control command and improving user satisfaction.

Description

technical field [0001] The present application relates to the technical field of Internet applications, in particular, to a method and system for controlling flow of distributed players. Background technique [0002] Currently, a video player generally refers to software capable of playing media files stored in the form of digital signals, and also refers to electronic device products capable of playing media files. Except for a few wave files, most video players carry video and audio decoders and display components to restore compressed media files, and video players also have a built-in set of conversion and caching algorithms. Of course, most video players can also support playing a single audio file or a single video file. [0003] The general process is: [0004] enter. Read original data from a file or network, such as x.avi, x.mov, rtsp: / / xxx, to analyze the original data, such as a file, first analyze the file format, obtain audio and video encoding parameters fro...

AI Technical Summary

Problems solved by technology

The amount of video and audio data is very large. After the playback starts, the video and audio data in the downlink channel will continuously pour in, blocking the downlink channel.

At this time, if control actions such as Pause, Seek, and Stop are to be issued, the upstream channel will send the control command, but when the control command response returns from the downstream channel, it will be blocked by a large amount of video and audio data

Only when a large amount of data in the downlink channel is consumed can the response of the control command be received. The whole process is quite long or even blocked forever. The user experience will be very bad and bandwidth will be wasted.
