Embodiments of the present invention disclose a method and an apparatus for acquiring video coding compression quality. The method may include: acquiring video stream information, where the video stream information includes a video frame type, a video frame size, a frame rate and a bit rate; calculating video content complexity according to the video stream information, where the video content complexity includes temporal complexity, or space complexity, or both the temporal complexity and the space complexity; and calculating video coding compression quality according to the bit rate, the frame rate and the video content complexity. In the embodiments of the present invention, the video coding compression quality may be acquired as long as the video frame information, the bit rate, the frame rate and the video content complexity of a video stream are acquired. The video coding compression quality may be used in subsequent video quality assessment. This process greatly reduces video quality assessment complexity and the assessment may be performed in real time. In addition, because impact of video content characteristics (namely, video content complexity) and impact of a frame rate are considered, the assessed coding compression quality meets the subjective feeling of human eyes better. |
