摘要
针对H.264格式视频编解码器在嵌入式平台上的应用需求,对H.264格式视频编解码器的优缺点进行了理论性介绍,在对H.264视频编解码器研究的基础上,实现了基于嵌入式S3C6410平台的H.264解码器和播放器的移植。对基于Linux的开源编解码库ffmpeg在嵌入式S3C6410平台上进行了移植,实现了嵌入式平台上对H.264码流的解码和播放。对视频流图像分别在PC机和目标板上的解码效果进行了详细比较,论证了研究的正确性,证明了此研究具有工程应用价值。
According to the requirement of H.264 format video codec based on embedded platform application,a theoretical introduction of the advantages and disadvantages of H.264 format video codec is given.The H.264 decoder and player transplantation on embedded S3C6410 platform is realized based on a research of H.264 video codec.Then,the transplantation of Linux-based open source codec library ffmpeg is realized on embedded S3C6410 platform,realizing H.264 bit stream decoding and playback on embedded platform.Finally,the video stream image decoding results respectively on PC and target board are compared in detail,which proves the correctness of the research as well as the value of its engineering application.
