Video encoding according to H.265 standard

U ovom završnom radu opisana je H.265/HEVC normu za kompresiju videa, te njezina poboljšanja u usporedbi sa njenim prethodnikom H.264/AVC. Korištenjem programa FFmpeg, napisan je programski kôd u Python programskom jeziku kojim su kodirane različite video datoteke H.264 i H.265 koderima. Primjenom dvije objektivne metode ocjenjivanja kvalitete videa PSNR i SSIM napravljena usporedba kvalitete komprimiranih videa. Analizom rezultata je utvrđeno da je H.265 postigao prosječno poboljšanje kvalitete od 1.6 dB prema PSNR rezultatima i 0.0143 prema SSIM rezultatima u usporedbi s H.264 za istu kodnu brzinu, što pokazuje da je novi standard uspješno unaprijedio efikasnost kompresije.In this final thesis the H.265/HEVC standard for video compression is described, as well as its improvements in comparison with its predecessor H.264/AVC. Using the FFmpeg application, a program code has been written in Python, with which various video files have been encoded by H.264 and H.265 encoders. Two objective methods for video quality measurement, PSNR and SSIM, have been used for comparison of compressed videos quality. Measurement results have shown that H.265 achieved the average quality improvement of 1.6 dB according to PSNR results and 0.0143 according to SSIM results in comparison with H.264 for the same bitrate, which indicates that the new standard has successfully improved compression efficiency
