Embodiment 1

[0025] This embodiment provides a video conference audio mixing method, which can be used for audio mixing under cloud computing conditions. It should be noted that the audio mixing resources (including the main audio mixing resource) described below in the embodiments of the present invention (Master-MP) and auxiliary mixing resources (Slave-MP)) can be hardware mixers or software-implemented mixing resources, which can be used to mix and encode audio. Wherein, the main audio mixing resource may be pre-designated from pre-created audio mixing resources, and after the main audio mixing resource is designated, other audio mixing resources are collectively referred to as auxiliary audio mixing resources.

[0026] Such as figure 1 As shown, the method includes:

[0027] Step S101, the main audio mixing resource receives the audio code stream sent by the auxiliary audio mixing resource, wherein there are one or more auxiliary audio mixing resources, and each auxiliary audio mixin...

Embodiment 2

[0062] This embodiment provides a video conference audio mixing device, which can be used to implement the video conference audio mixing method in Embodiment 1 of the present invention, such as image 3 As shown, the device includes: a receiving unit 10 , a judging unit 20 , a querying unit 30 and a distributing unit 40 .

[0063] The receiving unit 10 is set on the main sound mixing resource, and is used to receive the audio code stream sent by the auxiliary sound mixing resource, wherein there are one or more auxiliary sound mixing resources, and each auxiliary sound mixing resource is used for at least two conference sites Audio streams are mixed.

[0064] The main audio mixing resource can have its responsible sites and receive the audio streams of these sites, or it can only receive the audio streams sent by the auxiliary audio mixing resources.

[0065] The judging unit 20 is configured to judge whether the main sound mixing resource is fully loaded.

[0066] Due to th...

Abstract

The invention relates to the field of audio mixing, and specifically relates to a video conference audio mixing method and device. The method comprises the steps that a master audio mixing resource receives audio code streams sent by slave audio mixing resources, wherein there is one or more slave audio mixing resources, and each slave audio mixing resource is used for carrying out audio mixing on audio code streams of at least two conference places; judging whether the master audio mixing resource is fully loaded or not; searching an idle slave audio mixing resource when it is judged that the master audio mixing resource is fully loaded; distributing partial audio code streams received by the master audio mixing resource to the idle slave audio mixing resource when the idle slave audio mixing resource is searched; and after audio mixing is carried out on the partial audio code streams by the idle slave audio mixing resource, sending the processed audio code streams to the master audio mixing resource. Through adoption of the method and the device, the problem that in the prior art, the number of the conference places capable of accessing audio mixing is liable to be limited by the audio mixing processing capability is solved, and the limitlessly extendable intelligent audio mixing of the conference places with extra large number of squares can be realized.

Description

technical field [0001] The invention relates to the field of audio mixing, in particular to a video conference audio mixing method and device. Background technique [0002] Intelligent audio mixing is a core technology used in multi-party video conferencing. Its advantage is that, without human-computer interaction, the MCU platform can independently select the most suitable participants, mix their voices and send them to all participants, and meet several basic requirements at the same time: 1. Users do not need to apply or intervention; second, the conversation is clear and smooth, without interruption or noise; third, any site can interrupt at any time; fourth, the user will not hear his own voice. [0003] Under cloud computing conditions, unlike traditional multi-level conferences, all sound and image streams will be sent to the MCU platform in the data center for processing and exchange. With the enrichment of video application scenarios, there are more and more vide...
