I am trying to add a marker to all I frame by sending a "HELLO" message in
h264 metadata ( SEI_USER_DATA) however i could not find much success in it.

If anyone could help me out, your inputs would be highly appreciated.

ffmpeg -i input.mp4 -c copy -bsf:v h264_metadata=sei_user_data=‘hello’

I could not find a way to add/insert at a particular frame.

Thank you
