您可以使用ffprobe（随附于ffmpeg）收集有关多媒体文件的信息。有关多媒体文件总体内容的信息，请使用
ffprobe -show_streams -show_format DV06xx.avi
有关视频文件中每个帧的信息，请使用
ffprobe -show_frames DV06xx.avi
但是，ffprobe它没有像我最喜欢的工具Mediainfo那样检索到尽可能多的信息，例如，“ ffprobe”不显示视频第一帧的时间代码（尽管手册页另有说明）或录制日期。
如果mediainfo在命令行上运行，甚至可以请求XML格式的输出：
mediainfo --OUTPUT=XML DV06xx.avi
在我的示例中，输出为：
<?xml version="1.0" encoding="UTF-8"?>

添加可选参数-f将产生更详细的信息。
