The downloaded shanghaitech dataset is a video. How to convert it into a frame? Or can you put a download link to the Shanghai dataset? #29

Using FFmpeg Please refer to this: https://superuser.com/a/1346333

Just curious, do you set the fps during the conversion?

This is my code: I set it to 24fps (-r 24/1) as it shows in the detail of the video.

for %%F in (*.avi) do (
    If not Exist "%%~nF" MkDir "%%~nF"
    ffmpeg -i %%F -r 24/1 -qscale:v 2 %%~nF\%%~nF-%%3d.jpg
)
