How to get the GOP size of a video with ffmpeg (C)?

Question

Is there any way to get the gop size of a video I'm decoding using the ffmpeg C API, that isn't demuxing until I find an iframe?

AVCodecContext has an element for this but I'm not sure if it always work: int AVCodecContext::gop_size

I looked at that variable and it claimed my 15 gop size vid was 12. – necrosato Oct 04 '18 at 15:15
For me too always 12 while decoding – Olga Pshenichnikova Dec 04 '19 at 14:59
