The invention provides a video transmission method and a video transmission system. According to the video transmission method, a server acquires source data and performs H.264 encoding on the source data to obtain video data, whether the cache of the server is full is judged, and if the cache of the server is full, frame dropping is performed on the video data in the cache of the server in accordance with the rules of frame dropping, and the video data is added to the cache of the server. The method comprises the following steps: S1, the video data in the cache of the server is sent; S2, whether the video data in the cache of the server is sent successfully is judged, the successfully-sent video data is removed from the cache of the server and S3 is executed if the video data in the cache of the server is sent successfully, and dormancy is performed according to the rules of dormancy and S1 is executed after the end of dormancy if the video data in the cache of the server is not sent successfully; and S3, a client receives the video data sent by the server via a network, and plays the received video data according to the amount of video data cached in the cache of the client. By adopting the video transmission method and the video transmission system provided by the invention, a video can be played more smoothly.
Description
technical field [0001] The invention relates to the technical field of network data transmission, in particular to a video transmission method and system. Background technique [0002] With the popularization and rapid development of the Internet, more and more people begin to use various network communication tools, and real-time video technologies such as network video conferencing, video calls, and video surveillance are accepted, recognized and used by more and more people. These real-time videos have the characteristics of a large amount of transmitted data and high requirements for real-time performance. How to transmit stable and reliable real-time video data through the Internet has become a problem that cannot be ignored in real-time video transmission. [0003] In the prior art, when video transmission is performed on the Internet, the network bandwidth of the Internet is relatively small and the network fluctuates greatly, resulting in unsmooth and stuck video. ...
