Live video processing method and device and storage medium

Abstract

The embodiment of the invention relates to the technical field of video processing, and discloses a live video processing method. The method comprises the following steps of: obtaining live source video streams of various visual angles; obtaining a to-be-downloaded video slice of each view angle according to the live broadcast source video stream of each view angle; receiving a live broadcast watching request of a playing device, and the live broadcast watching request comprising a first live broadcast main view angle; and in response to the live broadcast watching request, sending the to-be-downloaded video slice of the first live broadcast main view angle and the to-be-downloaded video slice of at least one side view angle adjacent to the first live broadcast main view angle to a playingdevice. According to the live video processing method and device and the storage medium provided by the embodiment of the invention, bandwidth waste during panoramic video transmission can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of video processing, and in particular, to a live video processing method, device, and storage medium. Background technique [0002] With the popularity of live broadcasting, some new business experiences have also begun to be promoted gradually. Among them, 360-degree panoramic video live broadcasting has been welcomed by a large number of users, because this live broadcasting method allows users to choose their own viewing angles, and the user's sense of participation has been greatly improved. big boost. [0003] The existing 360-degree panoramic video broadcasting scheme is usually as follows: First, deploy N cameras (N is generally greater than 4) around the live broadcasting site to ensure that the cameras can cover the live broadcasting site 360 ​​degrees, and the optical axes of all cameras are on the same plane. N cameras capture N video streams and input them to the encoder, ...

AI Technical Summary

Problems solved by technology

[0004] However, the inventor found that at least the following problems exist in the prior art: after the above-mentioned N video streams are spliced ​​into a 360-degree panoramic video stream, they are directly sent to the playback device for decoding and playback, but the playback device generally displays at most 2 panoramic video streams at the same time. Therefore, splicing N video streams into a 360-degree panoramic video stream and sending it to the playback device will cause a waste of bandwidth during video transmission.
