ffprobe的输出格式：json、csv和xml

ffprobe拥有很多信息输出格式选项，你可以在默认格式（如我们在前例中看到的）、json、csv、xml、flat和ini输出格式中选择。

选择输出格式非常简单，在命令行中使用print_format <option> 即可。下面是几个输出如何查找show_format说明符的示例。

ffprobe的json输出

ffprobe -v error -hide_banner -of default=noprint_wrappers=0 -print_format json -select_streams v:0 -show_format simpsons_1080p2398_clip.mp4

        "filename": "simpsons_1080p2398_clip.mp4",
        "nb_streams": 2,
        "nb_programs": 0,
