Embodiment Construction

[0021] Attached below figure 1 The present invention will be further described.

[0022] A method for realizing network audio selection source based on FFmpeg, comprising the following steps:

[0023] a) Register audio and video codecs, register audio and video filters, and register audio and video multiplexers through FFmpeg;

[0024] b) Register and load related libraries for network and encryption;

[0025] c) Open N audio streams in the network, where N is a positive integer greater than or equal to 2, and obtain the corresponding decoder of each audio stream;

[0026] d) using a corresponding decoder to extract a single channel in the corresponding audio stream;

[0027] e) Merge the single channel extracted from each audio stream by using the audio mixing and merging filter and output it for playback.

[0028] Through the registration of various audio and video codecs, multiplexers, and filters, multiple network audio sources can be opened at the same time, and an ap...

Abstract

The invention discloses an implementation method of a network audio selection source based on FFmpeg, which comprises the following steps of: registering various audio and video codecs, multiplexers and filters, simultaneously opening a plurality of paths of network audio sources, selecting a proper audio encoder according to a novel audio, extracting a single sound channel, and carrying out confluence playing by using a proper audio filter. The multi-channel network audio selection output scheme based on ffmpeg is realized, the multi-channel audio transmitted from the network can be combinedand output, the transmission real-time performance is very high, and the multi-channel audio collection output requirement in practical application can be met.

Description

technical field [0001] The invention relates to the technical field of network audio source selection, in particular to a method for realizing network audio source selection based on FFmpeg. Background technique [0002] With the vigorous development of 5G wireless communication and network technology, network video conferencing and real-time audio and video transmission are more and more widely used in real life. At present, most of the audio receiving end plays a single audio source data, but there may be more than two audio sources in practical applications, and it is necessary to control multiple audio sources, output a certain audio data independently, or control multiple audio sources. output simultaneously. [0003] FFmpeg is a set of open source computer programs that can be used to record, convert digital audio and video, and convert them into streams. It provides a complete solution for recording, converting and streaming audio and video. However, when targeting...
