Abstract

The embodiment of the invention provides a video data transmission method and a transmission device. The video data transmission method comprises the following steps: acquiring network transmission quality between a video sending end and a video receiving end, and a video clip needing to be sent to the video receiving end; obtaining video frames obtained by video clip coding according to the network transmission quality, the network transmission quality and the number of key frames obtained by video clip coding being in a positive correlation relationship, and the network transmission qualityand the number of non-key frames obtained by video clip coding being in an inverse correlation relationship; and sending the acquired video frame to a video receiving end. According to the technical scheme provided by the embodiment of the invention, when the network transmission quality is better, the decoding time of the video receiving end can be reduced by sending more key frames, and the definition of video playing can be ensured; And when the network transmission quality is poor, the video data transmission quantity can be reduced by reducing the transmission of the key frames and increasing the transmission of the non-key frames, and meanwhile, the video playing fluency can be ensured.

Description

technical field [0001] The present invention relates to the technical field of computer and communication, in particular, to a video data transmission method and a transmission device. Background technique [0002] With the development of mobile terminals and network technology, more and more users start to watch videos online through terminals such as mobile phones, tablet computers, and personal computers. However, the playback effect of videos will be affected by network quality and terminal processing efficiency. Contents of the invention [0003] Embodiments of the present invention provide a video data transmission method and transmission device, and then at least to a certain extent, when the network transmission quality is good, the decoding time of the video receiving end can be reduced by sending more key frames, and the video data can be reduced. The buffer consumption at the receiving end can ensure the clarity of video playback; when the quality of network tra...
