摘要
H.264编解码器的软件实现是嵌入式应用领域的热门研究课题。在此介绍以S3C2440为硬件平台,在Linux开发环境下实现基于H.264的x264编码、ff mpeg解码以及ffplay解码播放的移植过程和方法。实验结果表明,在qcif分辨率下,可以获得近实时的解码和播放。最后针对视频流进行实时编解码和播放的要求,提出对编解码优化的方案。
Nowadays,the software realization of H. 264 encoder /decoder is the hotspot of the embedded application research. Implementation of H. 264 encoding and decoding in the Linux system baded on S3C2440 is introduced. The encoding code is based on x264, and the decoding code on ffmpeg eodec, and play on ffplay codec. The experimental results show that at the resolution of qcif,the near real- time decoding and playing can be gained. Aimming at real - time video decoding and playing based on the video streaming,the optimization of eodec options is given.
