  • Publication number: 20180262815
    Abstract: A video processing method, video processing apparatus, and a computer storage medium are also disclosed for implementing a solution for compensating for lost video frames that are lost during transmission. Lost video frame detection and compensation is implemented by separately numbering each video frame, at a data layer of transmission, with no need to perform additional encoding/decoding calculation, and without increasing a load of a server during lost frame compensation. A lost video frame is compensated for by inserting a compensation video frame after the lost video frame is detected, so as to ensure that a total quantity of video frames is not changed, thereby avoiding stalling at the playback end during a playback process because the quantity of video frames decreases, and ensuring smooth watching during video playback.
