ffmpeg 无法提取所有帧

Question

I need to extract all frames from a video.

I have tried this command:

ffmpeg -i battle1.avi outN-%d.png 

This video is 15 FPS with 45 seconds and I get this result:

 Could not get frame filename number 2 from pattern 'outN-d.png'. Use '-frames:v 1' for a single image, or '-update' option, or use a pattern such as %03d within the filename.
av_interleaved_write_frame(): Invalid argument

there is a way to solve?

Thanks !

Answer 1

In your batch file you need to escape the % with, ironically, a % :

ffmpeg -i battle1.avi outN-%%d.png
