1. 1. Cli  \paidashi\bin\ffprobe.exe

ffprobe -i 1.flv -print_format json -show_frames -show_format -show_streams -v 0

 

在外部程序调用并处理音频视频信息时，通过ffmpeg/ffprobe查看音频视频文件信息并输出为json格式是非常实用的功能,在终端输入以下命令：

 

ffprobe -v quiet -print_format json -show_format -show_streams #{source}

---------------------

#{source}部分替换为mp3文件所在路径。输出如下：
