Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and implementation examples.

[0016] figure 1 Shown is a system architecture diagram of an encoding method that supports simultaneous use of multi-encoding formats and multi-module processes proposed by the present invention, including a data acquisition module, a data encoding module, a data pool, a control pool, and several data usage processes. The data acquisition module is responsible for collecting audio and video data and sending it to the data encoding module; the data encoding module is equipped with a variety of encoders to support the encoding of various encoding formats, and encodes the collected data according to the requirements of the control pool and writes them into the data pool; The data pool is the storage area for audio and video data. This area is a ring logic storage area, where audio and video data in different formats are placed. The data pool re...

Abstract

The invention belongs to the technical field of network multimedia data coding, in particular to network audio and video data coding technology. The specific steps are as follows: the data use process Pi registers with the control pool; the control pool creates records for the data use process Pi; the data encoding module queries the control pool records; the data encoding module obtains real-time data from the data acquisition module; The read position RPi and the write position RPi read data from the data pool; execute steps 3, 4, and 5 in a loop until the data use process Pi does not need data, and notify the control pool to release the record information of the data use process Pi. Compared with the existing codec technology, the present invention proposes a coding method that supports simultaneous use of multiple coding formats and multiple processes, and can obtain audio and video data in different formats to meet the requirements of different network environments.

Description

technical field [0001] The invention belongs to the technical field of network multimedia data coding, in particular to network audio and video data coding technology. Background technique [0002] With the vigorous development of multimedia in Internet applications, more and more attention has been paid to audio and video codec technology. However, most of the existing codecs still use traditional technology, with a single input source and a single format output, and then shared between threads to support multi-threading. This technology makes each thread using the code stream affected by the encoding format, and cannot output the most suitable audio and video data according to the needs of different network environments. Contents of the invention [0003] Aiming at the problems existing in the traditional encoding and decoding technology of network audio and video data, the present invention proposes an encoding method that supports simultaneous use of multiple encoding...
