Problems solved by technology

[0004] However, in application scenarios with lower delay requirements, if the delay between the first image frame and the latest image frame of the live broadcast is too large when the broadcast starts, the viewing terminal adopts the above technical solution and needs to play the live video at double speed. At this time, it is easy to cause the live broadcast to freeze

Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0035] First, several nouns involved in this application are introduced:

[0036] Live broadcast refers to the playback mode in which the post-production synthesis and broadcasting of the video are carried out simultaneously. The live broadcast delay refers to the time difference between the acquisition moment of the live image frame on the live broadcast source and the playback moment of the live image frame on the live viewing terminal. For example, the live broadcast source starts streaming at 10:00:00. After the process of transmission and loading, the playback time of the screen of the live broadcast source at 10:00:00 seconds on the terminal is 10:00:03 seconds, then the above The time difference of 3 seconds is the live b...

Abstract

The application discloses a method, device, equipment and storage medium for playing live video streams, belonging to the technical field of live broadcasting. The method includes: pulling a live video stream from a content distribution server, the live video stream includes a sequence of live image frames, and the live image frames in the sequence of live image frames carry a cache time stamp, and the cache time stamp is used to instruct the content distribution server to cache The time of the live image frame; determine the start time of the live video stream based on the first pull time of the live video stream; The first live image frame; starting from the first live image frame, playing the live video stream. This method can control the delay time of live video stream playback, meet the live broadcast scene with lower delay requirements, and reduce the occurrence of live video stuttering at the same time.

Description

technical field [0001] The present application relates to the field of live broadcast technology, and in particular to a method, device, device and storage medium for playing live video streams. Background technique [0002] Today, live broadcast technology is widely used. For example, application development and application testing are completed by dedicated engineers. When test engineers find problems during application testing, they can use live broadcast to communicate with development engineers about the above problems. However, there is always a delay in live broadcast technology. question. [0003] In order to solve the delay problem in the live broadcast technology, the first delay threshold and the second delay threshold are set in the viewing terminal of the live broadcast system, and the viewing terminal plays the live video. After a period of live broadcast, the viewing terminal is relatively slow The time difference between the played image frame and the latest...
