Video frame caching and forwarding method and device, and computer device

Abstract

The invention relates to a video frame caching and forwarding method and device, computer equipment and a computer readable storage medium. The method comprises the following steps: receiving a videoframe of a video sharing terminal; if the received video frame is a key frame, clearing the video frame data in the buffer, storing the key frame in the buffer, and setting pointing positions of a head pointer and a tail pointer of the buffer to point to the key frame; and if the received video frame is not the key frame, moving the pointing position of the tail pointer backwards for one bit, andstoring the received video frame into the pointing position of the tail pointer in the buffer. According to the video frame caching method, the video sharing terminal only needs to send one piece of video frame data to the server for caching and forwarding, so that network congestion caused by sending the video frames to a plurality of video request terminals is avoided. The buffer only stores onekey frame at the same time, so that the real-time performance of the video frame stored by the buffer is ensured, the occupation of cache resources can be reduced, and the caching and forwarding efficiency of the video frame is improved.

Description

technical field [0001] The present invention relates to the field of live video broadcasting, in particular to a video frame buffering and forwarding method, device, computer equipment and computer-readable storage medium. Background technique [0002] With the development of live video technology, live video technology has been applied to all aspects of life. For example, live video technology can be used to synchronously rebroadcast the video frame data played by the video sharing terminal to other video request terminals to realize multiple video requests. Terminal playback content sharing. [0003] For example, in the field of network conferencing system or remote office, often the video sharing terminal needs to share the video sharing computer desktop with other video requesting terminals to display documents and the like. Because the key frame data of the desktop shared video is very large, but the subsequent video frame data does not change much, if the peer-to-peer...
