The invention provides a real-time communication transmission method and device and a real-time communication processing method and device. The real-time communication transmission method comprises the steps of: carrying out audio and video collection through target collection equipment corresponding to a first client, and obtaining a to-be-transmitted first audio and video; encoding the first audio and video to obtain a first video stream, non-key frames in the first audio and video being encoded by only referring to key frames in the same image group; and transmitting the first video streamto a second client through real-time communication connection between the first client and the second client. According to the method, the problem of poor timeliness of real-time audio and video communication caused by overlarge decoding time delay in an encoding and decoding mode in the prior art is solved.
Description
technical field [0001] The technical field of communication of the present application, in particular, relates to a real-time communication transmission method and device, and a real-time communication processing method and device. Background technique [0002] In real-time audio and video communication (RTC) scenarios, latency is an important technical indicator. When optimizing latency metrics, it is necessary to consider both control costs and not affecting user experience (ie, subjective video quality). [0003] In the related art, the RTC low-latency technology reduces the encoding delay at the acquisition end by adopting the LDP encoding configuration. figure 1 The frame types of the LDP encoding method and the reference relationship between frames are shown. like figure 1 As shown, the direction of the arrow indicates that it is referenced. Taking the frame with POC=3 as an example, it needs to refer to the 0th frame (long-term reference frame) and the 2nd frame (s...
