How to extract all HEVC i-frame images from a x265 video?

Question

I need to drop all the B-frames and P-frames, only keeping the I-frames to be saved as images.

I’m voting to close this question because , as explained by the ffmpeg tag: Only questions about programmatic use of the FFmpeg libraries, API, or tools are on topic. Questions about interactive use of the command line tool should be asked on https://superuser.com/ or https://video.stackexchange.com/. — Rob, Apr 17 '23 at 07:57
To my point of view, this is not surely an FFmepg command question. Potentially I was going to edit the source codes of FFmpeg to extract frames — 2474101468, Apr 18 '23 at 08:04

You can instruct the decoder to skip non-keyframes using -skip_frame.

ffmpeg -skip_frame nokey -i input.mp4 -vsync vfr img%04d.png

ffmpeg questions are off topic. Do not answer off topic questions. [answer] – Rob Apr 17 '23 at 07:58
ffmpeg Qs aren't off-topic. And this Q is not about "interactive use of the command line tool" – Gyan Apr 17 '23 at 10:15
