Disclosed are a method and a device for obtaining the video encoding compression quality. The method may comprise: obtaining video stream information, the video stream information comprising a video frame type, a video frame size, a frame rate and a code rate; calculating the complexity of video content according to the video stream information, the complexity of the video content comprising the time complexity or the space complexity or the time complexity and the space complexity; and calculating the video encoding compression quality according to the code rate, the frame rate and the complexity of the video content. According to the embodiments of the present invention, the video encoding compression quality may be obtained as long as the video frame information of the video stream, the code rate, the frame rate and the complexity of the video content are obtained, and may be used for subsequent video quality evaluation. The present invention greatly lowers complexity of the video quality evaluation, and can perform evaluation in real time. Meanwhile, because the effect of the video content characteristic (that is, the video content complexity) and the frame rate is considered, the evaluated encoding compression quality can better conform to a subjective feeling of the human eye. |
