Abstract

Provided are a method for automatically adjusting a live video code rate, a video transmission device and a server. The method (300) comprises: acquiring a current network bandwidth when the video transmission device currently pushes a video stream to the server (S301); performing discretization processing on the current network bandwidth to obtain a discretized current network bandwidth (S302); automatically adjusting the current set code rate according to the discretized current network bandwidth and the current set code rate of the video transmission device (S303); and pushing the video stream to the server based on the adjusted current set code rate (S304). The method can effectively relieve live broadcast lagging and live broadcast delay, and improves user experience. Moreover, after the current network bandwidth is obtained, discretization processing is firstly carried out, so that the frequent adjustment of the code rate is reduced, the oscillation of code rate adjustment is reduced, and the stability is improved.

Description

technical field [0001] The present invention generally relates to the field of live video technology, and more specifically relates to a method for automatically adjusting bit rates of live video, a video transmission device and a server. Background technique [0002] In the live broadcast process of the existing hand-held pan-tilt camera, the server pushes the code stream generally using the fixed code rate set in the early stage to push the stream, but in the actual use scenario, the quality of the live broadcast network changes dynamically and is unpredictable. Using a fixed bit rate to push streams may cause problems such as live broadcast freezes and increased delays during the live broadcast, which will affect the user's live broadcast experience. [0003] Therefore, in view of the existence of the above problems, the present invention proposes a method, system and computer storage medium for automatically adjusting the bit rate of live video. Contents of the inventi...
