Embodiment Construction
[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0040] The inventors of the present invention have found that the prior art strategy for controlling the transmission of live video on the Internet with limited bandwidth has seriously affected the user's online viewing experience. Therefore, there is an urgent need for a new method for controlling the transmission of live video on the Internet with limited bandwidth. Strategies to enhance users' online viewing experience.
[0041] In order to solve the above ...

The invention provides a video coding method and a video live broadcasting client. The method comprises the following steps of collecting a video image frame; determining the coding mode of the video image frame; when the coding mode of the video image frame is a first coding mode, calling the newly configured code rate control input parameter corresponding to the number of online terminals of the current playing live broadcasting video, wherein the code rate control input parameter is dynamically configured along with the change of the number of the online terminals of the current playing live broadcasting video; coding the video image frame according to the called code rate control input parameters; generating the coded video image frame. By using the method and the video live broadcasting client, the coding code rate of the video image frame can be dynamically changed according to the code rate control input parameter corresponding to the number of the online terminals of the current playing live broadcasting video, so that the goals of ensuring the transmission of the video in Internet with the limited band width and simultaneously improving the online watching experience of the user can also be realized.
Description
technical field [0001] The present invention relates to the technical field of video encoding, and more specifically, relates to a video encoding method and a live video client. Background technique [0002] In recent years, with the rapid development of the Internet, there are more and more applications for users to watch live videos online (such as live videos of professional leagues of major games). [0003] In the prior art, when the number of online users watching live video is too large, the expected bandwidth is often exceeded. At this time, two processing strategies are generally adopted: limiting the number of users accessing and temporarily applying for more bandwidth to make the live video available in limited bandwidth. transmitted over the Internet. However, both of the above two processing strategies have certain limitations. Among them, limiting the number of users to access leads to unsatisfactory user experience, and temporarily applying for more bandwidth ...
