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

Embodiment Construction

[0048] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0049] In one embodiment, such as figure 1 As shown, a method for controlling audio and video synchronization of streaming media is provided. This embodiment uses this method as an example to illustrate a terminal. It can be understood that this method can also be applied to a server, and can also be applied to a terminal and a server. system, and realized through the interaction between the terminal and the server. In this embodiment, the method includes the following steps:

Abstract

The invention relates to a streaming media audio and video synchronization control method and device, computer equipment and a storage medium. The method comprises steps of when an audio signal is acquired, a controller being triggered to begin to carry audio data corresponding to the audio signal; when carrying is completed, timestamp information corresponding to the audio data being obtained, and the timestamp information being determined based on the time when hardware generates interruption; caching the audio data and the corresponding timestamp information to a cache library; and when anapplication program acquires the audio data from the cache library, sending the audio data carrying timestamp information to the application program. By adopting the method, the application program can be ensured to normally perform audio and video synchronization processing, so a problem that audios and videos in streaming media cannot be synchronized is effectively solved.

Description

technical field [0001] The present application relates to the field of multimedia technology, in particular to a control method, device, computer equipment and storage medium for streaming audio and video synchronization. Background technique [0002] With the development of multimedia technology, streaming media streaming not only has a strong demand for traditional applications, but also creates new demands in industries such as video conferencing, distance education, and digital courts, and has higher requirements for terminals. For example, digital courts Users hope that the manufacturer can provide the function of burning CDs in real time. When the trial is over, the recorded CDs will be taken out immediately and sealed. Users hope that multimedia applications can provide higher-definition, more-channel streaming media streaming capabilities to meet the needs of users in different application scenarios. [0003] However, in the currently commonly used multi-core embedd...
