Good day! I just would like to as for help to encrypt a video frame by frame!

I know how to encrypt the image itself but from a video, extracting it, encrypting each image and then building it again is a different story. Can anyone help me please? thank you!

P.S.

Sorry for my bad english. :)

Why do you need to encrypt each frame and not just the entire stream?

If you encrypt a frame, you will not be able to use compression algorithms(spatial and temporal compression). You can chose to encrypt only the output of the compression algorithm(some numbers: mainly motion vector and delta changes) but you will have to decrypt data from multiple frames to display a certain frame. Knowing how video encoding works is mandatory.
