Kind Code:
A1
Abstract:
The embodiments of the present application provide a videoconference auxiliary stream processing method and device. The videoconference auxiliary stream processing method comprises: coding a videoconference auxiliary stream by using a coding window of a predetermined length; performing real-time bandwidth detection and traffic limitation on the videoconference auxiliary stream by sliding the coding window; and when the total code amount of a current auxiliary stream video frame in the coding window exceeds a bandwidth limit, performing frame drop on the current auxiliary stream video frame in the coding window, so that the total code amount of the auxiliary stream video frame in the coding window subjected to the frame drop does not exceed the bandwidth limit. The solution of the embodiments of the present application can improve the picture definition of the videoconference auxiliary stream, and improve user experience.
