Problems solved by technology

In WebRTC, the validity of inter-frame dependence of H264 is judged by the continuity of the serial number seq_num, so the loss of fec packets will lead to misjudgment of the legality of inter-frame dependence of H264, resulting in problems such as video freeze and inability to play

Abstract

The invention provides a video stream packet processing method and device, electronic equipment and a storage medium. The method comprises the following steps: judging whether a currently received video stream packet is a fec packet or a first packet of a video frame or a last packet of the video frame; if the currently received video stream packet is a fec packet or a first packet of a video frame or a last packet of the video frame, calculating a serial number of the currently received video stream packet and an interval between the serial number of the currently received video stream packet and a serial number of a first packet, the first packet being a packet of a complete frame stored in the stashframes of WebRTC or a packet in received fec packets; and comparing the interval with a preset interval threshold, and determining whether the currently received video stream packet is continuous with the first packet or not according to a comparison result, so that the occurrence of inter-frame dependency legality misjudgment of H264 in WebRTC caused by introduction of an Ulpfec function can be eliminated, and the H264 and the Ulpfec can coexist.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for processing video stream packets, electronic equipment and storage media. Background technique [0002] Ulpfec is a means to improve the QoS (Quality of Service) of weak networks. It is especially effective in weak network environments with high RTT (Round-Trip Time, round trip delay) and a certain packet loss rate. Its working principle is to perform XOR calculation on the data to be protected to generate redundant packets (hereinafter referred to as fec packets), so that when a data packet is lost, the redundant packet can be XORed with other data packets to recover the lost data packet. [0003] For Ulpfec, the same SSRC (Synchronization source, synchronization source) will be used for transmission with the H264 encoded video data packet, and a seq_num (Sequence Number, serial number) sequence will be shared. Since the video data encoded by H264 has a...
