Abstract

The embodiment of the invention discloses a high-definition video encoding and decoding playing method and device, equipment and a medium. The method comprises the following steps: generating a high-definition decoding result according to VR video data sent by VR acquisition equipment of an anchor end; performing double-channel video coding on the high-definition decoding result to obtain a background panoramic video stream and a high-definition video stream of at least one field angle, wherein the video quality and / or resolution of the background panoramic video stream are / is lower than that of the high-definition video stream; and providing the background panoramic video stream and the high-definition video stream of at least one field angle to an audience side so as to perform terminal playing of the high-definition video. By using the technical scheme of the invention, second starting can be improved when the terminal plays the video, and the problems of video playing lagging and black screen are relieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of webcasting, and in particular to a method, device, device and medium for encoding, decoding and playing high-definition video. Background technique [0002] With the application and development of webcasting technology, various livestreaming platforms present a variety of livestreaming content. In order to increase the attractiveness of live broadcast content to users and increase the interactivity, entertainment and sense of presence of live broadcast, virtual reality (Virtual Reality, VR) technology is integrated into live broadcast technology. [0003] In the VR live broadcast in the prior art, the host runs on the host end to provide VR high-definition panoramic video, encodes the high-definition panoramic video and sends it to the viewer end, and the viewer end decodes the encoded high-definition panoramic video to realize VR playback. [0004] VR videos require high resolution...
