Research and Implementation of Video Codec Based on FFmpeg

In this information age, a efficient video encoding/decoding technology will help reducing information redundancy, delaying processing, enhancing the robustness, improving visual perception of quality, increasing the compression ratio, etc. At first, this article describes the history of video encoding/decoding standards development. Research on the key technologies of H.264 coding standard currently which is most widely used. And this thesis will further analysis on the technical improvement of the new generation of High Efficiency Video Coding (HEVC) standard. At the same time, according to the international standard and theory, using ffmpeg and sdl2.0 function library, in win32 environment, and through MFC package the code, developed a software. Through the software debug, realized the encoding/decoding and playing H264 and HEVC format video in this thesis, meanwhile, it also realized the mutual format conversion between H264 and HEVC format.
