封装格式种类很多,例如 MP4,MKV,RMVB,TS,FLV,AVI 等等,它的作用就是将已经压缩编码的视频数据和音频数据按照一定的格式放到一起。例如,FLV 格式的数据,经过解封装操作后,输出 H.264 编码的视频码流和 AAC 编码的音频码流。 解码 将视频/音频压缩编码数据,解码成为非压缩的视频/音频原始数据。音频的压缩编码标准...

看过了FFMPEG中的一些结构体,可能对于怎么使用这些结构体写代码有些遗忘,尤其是如何处理音视频。接下来从头开始实现一个从MV中可以提取音频数据的小例子,但是由于ffmpeg不支持MP3onMP4的encoder,所以在输出文件的时候可以设置为AAC格式,如果设置为MP3输出格式,则不会导出音频数据。
需求:实现一个嵌入式linux上支持mp3/aac/wav文件的播放器 实现:所以考虑基于ffmpeg 实现一个嵌入式linux的播放器,这里主要应用ffmpeg的协议处理和音频解码能力,虽然网上的代码很多,不过由于版本的差异,例子程序接口存在差异,实现起来还是花了两天调试的时间;
