Video processing method and related device

Abstract

A method and a device for processing a video are provided. The method includes: fetching, from a buffer queue, an ith image frame of the video; calculating a sampling interval of the ith image frame; calculating a waiting time of the ith image frame; calculating a regulated waiting time of the ith image frame based on the waiting time of the ith image frame and a regulated waiting time of the (i-l)th image frame; determining a playing interval of the ith image frame based on the regulated waiting time of the ith image frame, the sampling interval of the ith image frame and a preset waiting delay; if the duration between a time point on which the (i-l)th image frame of the video starts to be played and a current time point is not shorter than the playing interval of the ith image frame, playing the ith image frame of the video on the current time point.

Description

technical field [0001] The present invention relates to the technical field of video control, in particular to a video processing method and a related device. Background technique [0002] At present, with the rapid development of network technology and the increasing popularity of mobile terminals, more and more users install applications such as video call software on mobile terminals, and the video image of the other party can be displayed in real time during the call through the video call software. [0003] As the mobile phone terminal on the side of the receiving end, the video image sent by the sending end can be received through the network. After receiving the video image, the receiver can play it in the following two ways: [0004] (1) The receiving end can play the video image of the frame immediately after receiving a frame of video image from the network. [0005] (2) After receiving the video image from the network, the receiving end does not play it immediat...

AI Technical Summary

Problems solved by technology

[0007] For the existing technology (1), since a frame of video image is played immediately after receiving a frame of video image from the network, when there is a delay in the network, the playback of the video image will jitter, and the video will be played as the network delay changes. The image will appear fast and slow, affecting the user's video call experience

[0008] For the existing technology (2), if the video images with a fixed number of frames are buffered in advance, since the current network congestion situation cannot be known in a timely and accurate manner, the fixed frame value that usually needs to be set in advance is difficult to accurately select, so buffering The size of the number of frames cannot accurately match the delay status of the current network

And pre-caching the video with a fixed number of frames and then playing it according to the collection interval will introduce a large cumulative delay and affect the real-time performance of the user's video call
