OpenCv API to extract I-frames

Does opencv-python have API to extract I-frames from a video?
I am using ffprobe to extract I-frames from video and passing frame numbers to opencv for manipulating frames but this requires iterate video frames in two steps; one for detecting I-frames and one for manipulating those.
so I searched for a direct way to extract I-frames from video using just opencv but nothing found.
If there is a solution, I'll be happy to hear it.

opencv is too high-level to do this. But you can use ffmpeg programmatically by using the libav functions in your code, to extract/read frames and decode them if you like to. OR you could change the openCV functions (it is open source!) or adapt a MyVideoCapture class (based on the open source VideoCapture class) to return additional frame information to the user.
