Hello,
I have a doubt, I think I remember reading how to do this in the past, but I can't remember if it was in gpac or the other known product (I'm not mentioning it here). The question is how to decrypt a specific segment, let's say, video_dash4.m4s if I have the xml I encrypted the full video with, and also (if needed) the dashinit.mp4 file

Then I want to encrypt it back (Only that segment)

Is that possible?
How?

Thanks!
