Problems solved by technology

[0004] In related technologies, when the streaming terminal obtains the encoded data from the server, because the display timestamp of the video data is smaller than the corresponding encoding timestamp, the streaming terminal will be out of sequence when decoding and playing the video data, resulting in audio video out of sync

Embodiment Construction

[0044] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0045] The related terms involved in the embodiments of the present application are introduced below.

[0046] Push Streaming: The process of transmitting the packaged content in the acquisition stage to the server.

[0047] Streaming terminal: a terminal that executes the above process of transmitting the packaged content in the collection stage to the server. Taking the live broadcast scenario as an example, the streaming terminal is the terminal used by the host user (that is, the host terminal).

[0048] Pull stream: The server already has live content, and the process of pulling it from the specified address.

[0049] Stream-pulling terminal: The terminal that executes the above-mentioned pulling of live content from the server wit...

Abstract

The embodiment of the invention provides a time stamp processing method and device, a terminal and a storage medium, the method is applied to a plug flow terminal, the method comprises the steps of: obtaining m frames of video data, wherein the m frames of video data respectively correspond to m display timestamps, and m is an integer greater than 1; encoding the m frames of video data to obtain mframes of encoded data respectively corresponding to the m frames of video data; adjusting a target display timestamp in the m display timestamps to obtain an adjusted target display timestamp; adjusting a target coding timestamp in the m coding timestamps to obtain an adjusted target coding timestamp; and sending m frames of encoded data, wherein the adjusted target display timestamp and the adjusted target encoding timestamp to a server. According to the technical scheme provided by the embodiment of the invention, the occurrence probability of audio and video asynchronization can be reduced.

Description

technical field [0001] The embodiments of the present application relate to the field of Internet technologies, and in particular, to a time stamp processing method, device, terminal, and storage medium. Background technique [0002] B frame method (B frame) is a bidirectional prediction inter-frame compression algorithm. When compressing a frame into a B frame, it compresses this frame according to the difference between the adjacent previous frame, this frame and the next frame data. That is, only the difference between the current frame and the previous and previous frames is recorded. [0003] In the related art, when the B-frame method is used to compress and encode multiple frames of video data, a situation in which the display time stamp of the video data is smaller than the corresponding encoding time stamp may occur. Incorporate references figure 1 , the streaming terminal obtains 5 frames of video data, and the display timestamps corresponding to the 5 frames of ...
