[FFmpeg-user] Calculation of duplicated video frames in live stream

I'm trying to detect duplication of video frames in live streams. Such
situation occurs when encoder can't encode stream at specified fps. I see
few frames with the same pkt_size. I know that there is filter to detect
similar frames but such technique looks like overkill.
The simplest solution I see is to compare crc of frames.
Is my idea right? Have ffprobe such option? Thank you very much!
P.S. Command I currently use: ffprobe -hide_banner -v error -show_frames
-show_entries frame=media_type,key_frame,pkt_pts_time -i rtmp://host/path
