Ffmpeg 寻找类似ffprobe的程序来查询图像？

我需要从命令行探测大量图像，看看它们是否会打开

ffprobe在多媒体方面非常出色，但有人能引导我朝着类似的方向发展吗？我可以用它来制作图像，如果宇宙正在回应我对PDF和文档的祈祷

与ffprobe一样，除了使用

identify

。它告诉你像大小、格式、编码等一样思考。

$ file rooster.jpg 
rooster.jpg: JPEG image data, EXIF standard 2.21

$ file -b testsrc.png
PNG image data, 320 x 240, 8-bit/color RGB, non-interlaced

$ file insulated_concrete_forms.pdf
