I have receive a ctf mission which require us to extract something like flag{*******} from the video. As there is no way to attach a video, i have snapped its first 4 frames(which it seems to be looped later in some patterns). It will be great if I can learn some common skills from this challenge to improve my ctf skill in visual challenge.
I want to get the hidden message from this video, or getting its encoding rules.
