| Abstract: | 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. |
