Problems solved by technology
[0003] The traditional key frame processing method is generally that the video source terminal periodically sends key frames, and the server forwards the key frames to the terminal that plays the video to realize the acquisition of the key frame, and can ensure the picture of the terminal that plays the video by increasing the key frame forwarding frequency Display quality. However, key frames occupy much more resources than predicted frames. Increasing the forwarding frequency will greatly increase the resource usage, resulting in low forwarding efficiency for video key frames.

The invention relates to a video key frame forwarding method and apparatus, and a live video system. The method comprises the following steps: obtaining an arrival time required for the arrival of a next key frame of a video source terminal that forwards a video, wherein the key frame is a key frame periodically sent by the video source terminal; if the arrival time exceeds a time threshold of allowing timeout, sending a key frame request to the video source terminal, and waiting for the arrival of the key frame; and at the arrival of the key frame, receiving the arrival key frame, and forwarding the received key frame to a video request terminal. According to the video key frame forwarding method, when it is obtained that the arrival time required for the next key frame exceeds the time threshold of allowing timeout, the key frame request is sent to the video source terminal to avoid an overlong waiting time of the key frame so as to effectively improving the forwarding efficiency ofthe key frame.
Description
technical field [0001] The present invention relates to the technical field of video live broadcast, in particular to a video key frame forwarding method, device, video live broadcast system, computer equipment and computer storage medium. Background technique [0002] When performing live video broadcasting such as video conferencing, the terminal playing the video usually needs to call the video data of the corresponding video source terminal through the server, and the video data generally includes key frames (I frames) with complete information, forward prediction frames (P frame) and bidirectional predictive frame (B frame). However, when the terminal playing video obtains the live video of a certain video source terminal for the first time, the video screen can be normally displayed and the live broadcast can be started only after receiving the key frame data. [0003] The traditional key frame processing method is generally that the video source terminal periodically...
