Application audio isolation acquisition method and device, storage medium and equipment

Abstract

The invention provides an application audio isolation collection method and device, a storage medium and equipment. The method comprises the steps of collecting to-be-output sound data of a target application process in a sound card driving layer; storing the to-be-output sound data to a target sound cache region corresponding to the target application process; and reading the sound cache region in real time through an application fluidization control layer, obtaining the to-be-output sound data from the target sound cache region, and encoding the to-be-output sound data. The scheme has the positive effects that the cost is low, the system performance is not influenced, and the application does not need to be changed.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, in particular, to a method, device, storage medium and equipment for applying audio isolation and collection. Background technique [0002] Application streaming refers to running the application on the cloud, collecting and encoding the display output and sound output during the running of the application in real time, and then transmitting them to the terminal in real time through the network. The terminal decodes the output in real time, and the terminal side can control the application. Real-time transmission to the cloud through the network to realize the control of the application. [0003] In the prior art, there are mainly two ways to implement application streaming on the Linux system. One is to use a virtual machine to implement. In this way, each virtual machine only provides services for one client at the same time, and the voice of the application is The sound curren...

[0003] In the prior art, there are mainly two ways to implement application streaming on the Linux system. One is to use a virtual machine to implement. In this way, each virtual machine only provides services for one client at the same time, and the voice of the application is The sound currently played by the virtual machine system can be isolated and collected by directly collecting the sound currently played by the system; but because the number of virtual machines in this method is the same as the number of concurrent applications, there is a defect of high cost

Another method is to simultaneously stream multiple applications on a Linux system. This method is relatively low in cost, but when implementing application streaming on a Linux system, system sound collection is realized by accessing a virtual sound card device. In this method If you want to realize the sound collection of multiple application processes, you need to deploy a large number of virtual sound card devices, which will affect the stability of the system, and you need to modify the application to ensure that the application correctly outputs the sound to the corresponding virtual sound card.
