Abstract

The invention discloses a streaming media transmission method and device and a computer readable storage medium, and relates to the field of multimedia communication. The streaming media transmission method comprises the following steps: obtaining a nominal code rate of an alternative fragment of a streaming media file from a DASH description file of the streaming media file, and obtaining a peak value ratio from a presentation layer of the DASH description file; predicting the downloading rate of the next fragment by adopting a rate linear fitting model established according to the average downloading rate of the previous preset number of downloaded fragments; predicting the ratio of the code rate of the next fragment to the nominal code rate as a code rate ratio by adopting a code rate ratio linear fitting model established according to the actual code rate of the previous preset number of downloaded fragments; determining a predicted code rate corresponding to each candidate fragment according to the predicted code rate ratio of the next fragment and the nominal code rate; and according to the predicted downloading rate, the code rate ratio and the nominal code rate, selecting a fragment from the alternative fragments for transmission. Therefore, the video transmission quality is improved.

Description

technical field [0001] The invention relates to the field of multimedia communication, in particular to a streaming media transmission method, device and computer-readable storage medium. Background technique [0002] DASH (Dynamic Adaptive Streaming over HTTP, adaptive streaming media transmission) technology has the characteristics of multi-stream fragmentation, and is often used to transmit high-definition, 4K, 8K, VR (Virtual Reality, virtual reality) and other streaming media under mobile networks such as 5G video. The current video application (App) usually determines the bit rate of video playback according to the network bandwidth. Contents of the invention [0003] After analysis, the inventor found that in the related technologies, the terminal only selects the video bit rate based on the current bandwidth, and the fluctuation of the network bandwidth will lead to untimely buffering and video playback freeze. In addition, the dynamic bit rate characteristics of...
