Since it can be variable, you will have to analyze yourself by counting
the distances:

$ ffprobe -of default=noprint_wrappers=1 -show_entries frame=key_frame input.file

Use "-g":
ffmpeg -i input.file -c:v outputcodec -c:a copy -g gopsize output.file
("gopsize" stands for a number you have to insert.)
