how can i get information of macroblocks, motion vectors, etc
Hello, I would like to know, how can I use opencv to get information relative to coding process as macroblocks, motion vectors
I want to read a .mp4 file get information (motion vector) and encrypt the motion to see the blurred visual at the moment to only encrypt these data.
My regards! Please help me.
if you meant the internal motion vectors, used in the compression -- you can''t from opencv
(you'd probably have to hack into libffmpeg directly for this)
