This paper mainly deals with an evaluation of video codecs used in todays applications. The paper begins with a short introduction to video quality evaluation methods. It is focuses on the objective measurement methods including Peak to Signal Noise Ratio (PSNR), Structural Similarity (SSIM), and Mean-Singular Value Decomposition (M-SVD). Then, four different video sequences are chosen to evaluate four video codecs, concretely H.264, VP8 concretely Dirac, Flash, VP8 and H.264. These codecs were tested on application developed in C++ wit FFmpeg implementation. The graphs at the end of this paper show the results of the tests in detail.
