Abstract

The invention discloses a video code rate control method, a video transcoding processing method, a video transcoding processing device and machine equipment. The method comprises the following steps:taking each frame of video image data in a video stream as the current frame of video image data, and carrying out video content detection on a preset number of frames of continuous video image data relative to the current frame of video image data; calculating the video change information of the current frame of video image data through the video contents respectively corresponding to the continuous preset number of frames of video image data obtained through detection; and adaptively updating the code rate corresponding to the current frame of video image data according to the video change information. Therefore, each frame of video image data in the video stream has a corresponding code rate, and is obtained by operation according to the video change of the frame of video image data, sothat the dynamic change of the effective code rate of the video stream is realized, the video stream is suitable for each frame of video image data, and the effective and accurate control of the coderate is realized.

Description

technical field [0001] The present invention relates to the technical field of Internet applications, in particular to a video code rate control method, video transcoding processing method, device and machine equipment. Background technique [0002] With the rapid development of video application technologies, more and more video services are implemented based on the Internet, and users can download and play video streams provided by the video services through the Internet. In the video service, Internet bandwidth is an extremely valuable and important resource, so it is often necessary to limit the bit rate of the video stream by means of the encoding process, so that the download of the video stream will not occupy too much bandwidth. [0003] The X264 encoder applied to the H.264 encoding standard supports user-specified code rate, but does not dynamically adjust the code rate so that the specified code rate is suitable for one or several frames of video image data in the...
