Problems solved by technology
[0004] In the field of mobile video live broadcasting, the encoding method usually uses a hardware encoder, and the restart process of the hardware encoder has a time-consuming problem. If the working time of the two hardware encoders is not well connected due to the restart of the hardware encoder, If the interval is longer, it will lead to discontinuity of the live video, causing the viewer to freeze

The invention relates to the technical field of network live broadcast, and provides a live video hardware encoder control method and device, computer equipment and a storage medium. The method comprises the following steps: creating a first hardware encoder by using a first encoding parameter through a first thread, and encoding the live video data to obtain first video encoding data; acquiring a second encoding parameter according to a real-time network bandwidth, when a hardware encoder is switched, creating a second hardware encoder through a second thread according to the second encoding parameter, acquiring first video encoding data encoded by the first hardware encoder and second video encoding data encoded by the second hardware encoder, and continuously sending the first video coded data to the video receiver, and switching to send the second video coded data to the video receiver until a preset trigger condition is met. Seamless switching can be achieved in the switching process of the two hardware encoders, and live video jamming is reduced.
Description
technical field [0001] The embodiments of the present application relate to the technical field of network live broadcasting, and in particular to a method, device, computer equipment and storage medium for controlling a live video hardware encoder. Background technique [0002] In the process of webcasting, due to the variety of network environments where the anchor and viewers are located, they often encounter the problem that network bandwidth fluctuations affect the viewing experience. Therefore, in the process of broadcasting on the anchor side, it is necessary to continuously adjust the video encoding parameters according to the current network bandwidth in real time to adapt to the network bandwidth and prevent poor network conditions from encoding at a higher bit rate, which will lead to further network degradation. Congestion causes stuttering, or the network has recovered well, but the encoding has been maintained at a lower bit rate, resulting in poor video qualit...
