ffmpeg播放器可以用来记录、转换数字音频、视频，并能将其转化为流的开源计算机程序。采用LGPL或GPL许可证。它提供了录制、转换以及流化音视频的完整解决方案。它包含了非常先进的音频/视频编解码库libavcodec，为了保证高可移植性和编解码质量，libavcodec里很多code都是从头开发的(Bitstream filters for editing metadata in H.264, HEVC and MPEG-2 streams Experimental MagicYUV encoder TiVo ty/ty+ demuxer Intel QSV-accelerated MJPEG encoding native aptX and aptX HD encoder and decoder NVIDIA NVDEC-accelerated H.264, HEVC, MJPEG, MPEG-1/2/4, VC1, VP8/9 hwaccel decoding Intel QSV-accelerated overlay filter mcompand audio filter acontrast audio filter OpenCL overlay filter)

使用Visual C++编程工具开发音乐播放器(Using Visual C++ programming tools developed music player)

命令行下可直接运行可将WAV转成MP3等格式 ffmpeg -i a.wav a.mp3 (命令行下可直接运行可将WAV转成MP3等格式 ffmpeg-i a.wav a.mp3 )

wav文件的与处理，包括预加重，分帧，合并，测试通过(wav files with the treatment, including pre-emphasis, sub-frame, combined, tested through)

rgb顺序的视频图片转换为bgr格式的方法，曾经困扰了我一阵子(rgb sequence of video images converted to bgr format, had bothered me for a while)

说明：  用dxshow编写的视频播放器。。。。。。。(Dxshow prepared to use video player。。。。)

能实现视频帧格式的选择，前一帧的播放，整个视频的文件播放(Can realize the video frame format of choice, before playing a frame, the video file playback )

这是一个数字信号处理的函数库,包括FFT变换，各种滤波算法， 如果你要编写数字信号处理相关的程序，这是个不错的选择(This a digital signal processing functions, including FFT, various filtering algorithm, if you want to prepare digital signal processing related to the procedure, which is not a bad choice)

说明：  用于移动节点定位算法 Centroid算法以及其改进算法(For mobile node localization algorithm Centroid algorithm and its algorithm are proposed)
