在这个信息时代，高效的视频编解码技术将有助于减少信息冗余、延迟处理、增强鲁棒性、改善视觉质量、提高压缩比等。本文首先介绍了视频编解码标准的发展历史。对目前应用最广泛的H.264编码标准的关键技术进行研究。并对新一代高效视频编码(HEVC)标准的技术改进进行了深入分析。同时，根据国际标准和理论，利用ffmpeg和sdl2.0函数库，在Win32环境下，通过MFC封装代码，开发了软件。通过软件调试，实现了H.64和HEVC格式视频的编解码和播放，同时实现了H.64和HEVC格式的相互转换。
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.
