TRANSCODER, METHOD AND DEVICE FOR CONTROLLING CODE RATE |
摘要 |
A method and device for controlling a code rate are provided, and this application relates to a video communication technology. The method for controlling a code rate includes the following steps. An output target bit of a current frame is acquired, where the current frame is a currently processed input frame. A target quantization parameter is acquired according to the output target bit by utilizing a nonlinear code rate control model. The present invention is applicable to transcoding between compressed videos.
