A data processing method, device, electronic device and storage medium

Abstract

The present application provides a data processing method, device, electronic equipment, and storage medium. The method includes: receiving at least one data packet sent by the sending end in real time; Judging whether to adjust the storage space size of the receiving buffer according to the code rate change rate corresponding to the first data packet that will be put into the receiving buffer at present; if the code rate change rate corresponding to the first data packet is positive and greater than the first preset If the threshold is set, the storage space of the receiving buffer is increased; if the code rate change rate corresponding to the first data packet is negative and less than the second preset threshold, the storage space of the receiving buffer is reduced. This application can dynamically adjust the storage space size of the receiving buffer when the code rate change rate corresponding to the data packet to be put into the receiving buffer reaches the adjustment threshold, so that the pressure on the receiving end will not be too large, and the restored Audio and video are also relatively smooth and complete.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, to a data processing method, device, electronic equipment, and storage medium. Background technique [0002] During the transmission of real-time audio and video streams, the receiving end will set up a receiving buffer to buffer the audio and video streams (data packets) transmitted from the sending end to reduce the probability of packet loss. [0003] In the prior art, the size of the storage space of the receiving buffer is fixed, if the size of the storage space of the receiving buffer is set too large, it will cause greater pressure on the receiving end; if the size of the storage space of the receiving buffer is set Too small, packet loss occurs in the data packet, and / or the code rate of a certain audio and video frame is relatively large (that is, the amount of data included in the audio and video frame is large, so the corresponding data packets of th...

[0003] In the prior art, the size of the storage space of the receiving buffer is fixed, if the size of the storage space of the receiving buffer is set too large, it will cause greater pressure on the receiving end; if the size of the storage space of the receiving buffer is set Too small, packet loss occurs in the data packet, and / or the code rate of an audio and video frame is relatively large (that is, the amount of data included in the audio and video frame is large, so the corresponding data packets of the audio and video frame are more or The total amount of data contained in the data packet corresponding to the audio and video frame is relatively large, and the data packet of the audio and video frame will occupy more storage space in the receiving buffer), which will cause the receiving buffer to be blocked, so that the receiving The audio and video freezes finally restored on the terminal
