Abstract

The invention discloses a generation method and device of a playback video file. The method comprises that video stream data is grabbed, a video stream fragment is generated according to the grabbed video stream data, the generated video stream fragment is set, and the set video stream fragment is stored and further called during playback. Compared with the prior art in which the playback video file is not generated before live streaming is completed, the video stream fragment that can be called and played back by a user can be generated in the live streaming process, the problem of playback delay of the live streaming video is solved effectively, time to wait for playing back the live streaming video is shortened, and user experience is ensured. The video stream fragment is set, the size of the video stream fragment is relatively small, so that the video stream fragment of the relatively small size can be set in shorter time, namely, the whole video stream data is set basically after that live streaming is completely, and the problem of playback delay of the live streaming video is solved further.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method for generating a playback video file and a device for generating a playback video file. Background technique [0002] Streaming data is data that can be transmitted on the network in a streaming manner, and large-scale website systems usually rely on a content delivery network (Content Delivery Network, CDN) to transmit the streaming data. [0003] During the live video broadcast, the live video broadcast end pushes the real-time recorded video stream data to the node server in the content distribution network, and the node server will cache the received video stream data, and after the live video broadcast ends, all the cached video stream data will be The data cache is a playback video file in a specified format, such as an mp4 file, for users to call and watch back. [0004] However, the playback video file in the prior art is generated after the live ...
