Problems solved by technology

[0003] However, in the currently commonly used multi-core embedded systems, due to the limited CPU performance of the embedded system, the load on the central processing unit is also getting higher and higher, resulting in a freeze phenomenon in the system. Accumulation in the driver can easily lead to the problem that the audio and video cannot be synchronized

Abstract

The present application relates to a control method, device, computer equipment and storage medium for audio and video synchronization of streaming media. The method includes: when the audio signal is acquired, triggering the controller to start transporting audio data corresponding to the audio signal; when the transport is completed, acquiring time stamp information corresponding to the audio data, the time stamp information is based on the Determine the time when the hardware interrupts; cache the audio data and the corresponding timestamp information in the cache library; when the application program obtains the audio data from the cache library, send the audio data carrying the timestamp information to the application. The adoption of the method can ensure that the application program can normally perform the audio and video communication synchronization processing, thereby effectively solving the problem that the audio and video cannot be synchronized in the streaming media.

Description

technical field [0001] The present application relates to the field of multimedia technologies, and in particular, to a control method, apparatus, computer equipment and storage medium for audio and video synchronization of streaming media. Background technique [0002] With the development of multimedia technology, streaming media push streaming is not only in great demand in traditional applications, but also has new demands in video conferencing, distance education, digital court and other industries, and has higher requirements for terminals, such as digital court Users hope that the manufacturer can provide the function of real-time CD recording, and when the trial is over, the recorded CD will be immediately taken out and sealed. Users hope that multimedia applications can provide higher-definition and more channels of streaming media streaming capabilities to meet the needs of users in different application scenarios. [0003] However, in the currently commonly used ...
