使用ffprobe 查询wav文件信息

使用ffprobe 查询wav文件信息

安装

安装过程和ffmepg相同不在赘述

不带参数查询文件信息

ffprobe ZH_biaobei_标准合成_甜美女声_楠楠_5_5_5_6_1_4047db9ffe21ffc845816028a9fdd120.wav

去除不必要的日志

ffprobe -loglevel quiet ZH_biaobei_标准合成_甜美女声_楠楠_5_5_5_6_1_4047db9ffe21ffc845816028a9fdd120.wav

使用-show_format

ffprobe -loglevel quiet -show_format ZH_biaobei_标准合成_甜美女声_楠楠_5_5_5_6_1_4047db9ffe21ffc845816028a9fdd120.wav

使用-print_format json输出为json格式

ffprobe -loglevel quiet -show_format -print_format json  ZH_biaobei_标准合成_甜美女声_楠楠_5_5_5_6_1_4047db9ffe21ffc845816028a9fdd120.wav

使用 -show_format -show_streams

ffprobe -loglevel quiet -show_format -show_streams -print_format json  ZH_biaobei_标准合成_甜美女声_楠楠_5_5_5_6_1_4047db9ffe21ffc845816028a9fdd120.wav
