Can you tell me the command for extracting the index of key frames from a video using ffmpeg
in Windows. I tried
ffprobe -select_streams v -show_frames \-show_entries frame=pict_type \-of csv bbb480.avi \| grep -n I | cut -d ':' -f 1 > frame_indices.txt
but this error is displayed:
'grep' is not recognized as an internal or external command, operable program or batch file
