Abstract

The invention discloses a data transmission method and device and a nonvolatile storage medium. The method comprises the following steps: acquiring a first transmission code rate when acquisition endequipment sends a multimedia data stream; when the first transmission code rate is greater than the bandwidth threshold, adjusting the coding strategy of the multimedia data stream to obtain a targetcoding strategy; encoding the multimedia data stream by adopting the target encoding strategy, and continuously detecting a second transmission code rate of the multimedia data stream after the multimedia data stream is encoded by adopting the target encoding strategy; and when the second transmission code rate is smaller than or equal to the bandwidth threshold, stopping adjusting the encoding strategy, and continuing to send the multimedia data stream. The technical problems that in the image transmission process, due to the fact that the network transmission bandwidth is not enough, a userreceiving end cannot receive a data packet of a complete frame of a picture, a video is blocked or a black screen is caused, and the user experience is influenced are solved.

Description

technical field [0001] The present application relates to the field of data transmission, in particular, to a data transmission method and device, and a nonvolatile storage medium. Background technique [0002] At present, in the process of image encoding, transmission and decoding, the acquisition end usually collects images at a fixed frame rate, and all the acquired images enter the encoder for encoding; after the encoding is completed, the encoded images are transmitted to the receiving end in accordance with the encoding sequence , and then decoded and displayed by the receiver. In this case, the data transmission is greatly affected by the bandwidth of the transmission network. If the transmission bandwidth is not enough, it is easy to cause video freeze or black screen at the receiving end because the data packet of the complete frame of the image is not received, thus affecting the user experience. It may even cause users to not be able to use it normally. [0003]...
