Abstract

The embodiment of the invention discloses a code rate control method and a device of video encoding. The method comprises a step of obtaining the collection frame rate of video data when the video data collected by a camera is obtained, a step of judging the collection frame rate by using a preset target frame rate, and obtaining code rate control information according to a judgment result and the collection frame rate, and a step of controlling the code rate of the video data encoding according to the code rate control information. The uniform adjustment of the collection frame rate can be realized, and the stability of the code rate obtained after video data encoding is maintained.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a video coding code rate control method and device. Background technique [0002] Due to the different processes and technologies of the cameras, the acquisition frame rate of video data is not uniform, and for the same camera, environmental factors will also affect the acquisition frame rate. During the acquisition of video data, the acquisition frame rate always fluctuates within a certain range, which makes the acquisition frame rate and the required frame rate quite different. The bit rate is unstable, which increases the packet loss rate of video data, making the video effect freeze. Contents of the invention [0003] Embodiments of the present invention provide a code rate control method and device for video encoding, which can realize unified adjustment of the acquisition frame rate, and further maintain the stability of the code rate obtained after encoding v...
