我去了上游媒体信息并看到了这个页但无法理解要投票给哪个功能，因此它将提供更多元数据信息。对于图像。
我也搜索了本地联机帮助页以及 --help 但没能走得太远。我确实知道 mediainfo 更适合视频和音频文件而不是图像，但如果一个工具可以完成这一切，那就太好了。
我正在运行 exiftool 10.80-1 并且
$ mediainfo --version
MediaInfo Command line,
MediaInfoLib - v18.03
关于 Debian 测试。

您正在寻找的是mediainfo支持 EXIF 元数据（据我所知，这不是该页面上列出的提案之一）。如果您想要该功能，您应该向他们建议。
