Video coder-based code rate control method and device, and video server

摘要

The invention is applicable to the field of videos and provides a video coder-based code rate control method and device, and a video server. The method comprises the following steps: in the video playback process, when a code rate needs to be switched, modifying time stamps of frames transmitted to the video coder in a switching process; transmitting, to the video coder, the frames having modified time stamps; and for each frame output by the video coder, restoring the time stamp of the output frame to be the original time stamp. The present invention avoids the stuttering resulted from interruption of coding, providing a very smooth switching process.
