Abstract

The invention provides a real-time video transmission method, which relates to the field of data transmission, is applied to a video sending end in a real-time video transmission system, and comprisesthe following steps of: obtaining an available bandwidth and an available frame rate according to feedback information sent by a server; Performing frame loss processing on the video data according to the available bandwidth and the available frame rate to obtain video data after frame loss processing; According to the available bandwidth and the available frame rate, encoding the video data subjected to frame loss processing to obtain encoded video data; And sending the encoded video data to a server. an available bandwidth and an available frame rate are obtained according to feedback information sent by the server, the real-time video transmission is carried out on the video data, then the video data is subjected to frame loss processing, and then the video data subjected to the frameloss processing is coded and sent, so that the video code rate is smoothened by the real-time video transmission, and the self-adaptive coding adjustment is realized, thereby ensuring the image quality and fluency of a video sent by a video sending end in real time in a weak network environment.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a real-time video transmission method. Background technique [0002] With the continuous development of network technology, Internet video transmission technology has been widely used. The real-time nature of Internet video makes it possible, for example, to transmit live video streams in classrooms or conference rooms. In Internet real-time video transmission, not only a large amount of video data is transmitted, but also real-time video transmission has high requirements for video delay and picture quality. [0003] In order to ensure the quality of real-time video transmission, it can be designed based on transmission protocols such as TCP (Transmission Control Protocol, Transmission Control Protocol) or RUDP (Reliable User Datagram Protocol, Reliable User Datagram Protocol). TCP can overcome the problem of packet loss through the retransmission of the transport layer. RUDP ...
