Abstract

The invention provides a video-based key frame request method and device, equipment and a storage medium, and the method comprises the steps: repeatedly transmitting a key frame request to recording equipment every preset first time until a complete key frame is received or repeatedly executing N times, wherein the key frame request is used for requesting a key frame, and N is a positive integer greater than or equal to 1; and then receiving a key frame sent by the recording device. Therefore, the problem that in the prior art, a playing device can only wait for a recording device to send out a key frame, so that a video cannot be normally played easily can be solved, the video playing continuity is ensured, and the video playing effect is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of video technology, and in particular, to a video-based key frame request method, device, device, and storage medium. Background technique [0002] With the development of video technology, video transmission technology has been applied to various fields. In the field of video transmission, the recording device as the recording end needs to send key frames to the playback device as the playback end; furthermore, the playback device can start video recording according to the key frame play. [0003] However, in the prior art, once the playback device does not receive the key frame in time, the video cannot be played normally, and even a black screen or blurred video occurs. However, the playback device can only play the video after the key frame is sent by the recording device, and the video may not be played normally. Contents of the invention [0004] The embodiment of the present app...
