Abstract

The invention provides a real-time streaming media transmission method and device and electronic equipment, and the method comprises the steps: receiving real-time streaming media, and obtaining an input frame sequence of the real-time streaming media; calculating the code rate of the real-time streaming media according to the input frame sequence; identifying key frames in the frame sequence, andcalculating the number of unit frames between two continuous key frames; calculating the number of discarded frames according to the bandwidth, the code rate and the number of unit frames between thekey frames, and generating a packet loss mapping table; and transmitting the modified real-time streaming media according to a frame loss rule and a packet loss mapping table.

Description

technical field [0001] The present application relates to the field of data transmission, in particular, to a real-time streaming media transmission method, device and electronic equipment. Background technique [0002] In the existing real-time audio and video communication, it is generally adopted that the terminal A transmits the video stream uplink to the video server, and then the video server downlinks the video stream to the terminal B. When the transmission network from the video server to the terminal B is congested, in order to make the The video on terminal B will not experience accumulated delays and freezes. Usually, when congestion occurs, terminal A is notified to reduce the resolution and encoding bit rate sent, so that terminal B will receive a smooth video stream. Although this can solve the problem of fluency, it loses the clarity of the video. Contents of the invention [0003] The purpose of the embodiment of the present application is to provide a re...
