Reference: Detailed explanation of the command

Get the last frame of the video (currently only one frame every 50 milliseconds, that is, 0.05 seconds, to output the picture)

ffmpeg -i C:\ds.mp4 -r 20 -f image2 C:\ds_image-%05d.jpeg

Among them, 20=1/0.05,
if you want to output the picture to a certain directory, you need to create a new folder in the C drive first, otherwise an error will be reported, and then execute the command.

ffmpeg -i C:\ds.mp4 -r 20 -f image2 C:\ds\ds_image-%05d.jpeg
