 Today we're going to be solving the hidden message from July 15th 2016 if you watch that it just flashed black and white Some people thought this might be Morse code, which is a good guess But if you control you to look at The source code and we look for the keywords which are the tags for the video. You can see I wrote bar code I even gave you a hint of frame one by one res so Some people were able to figure this out with out that guess They figured it might be a barcode and they were right if not. I pretty much told you right there So let's go ahead and the first thing we're going to do is we are going to download that video So I'm using YouTube DL to download that video Next thing we do is we're going to extract all the frames from it. So Ffmpeg Dash I the name of the video and then we're going to output as PNG files I'm going to label it IMG and then this percent 3d just means it's going to put a three-digit number there Because if I didn't it would go 1 2 3 4 5 6 7 8 9 10 11 12 13 And if you were to put those in alphabetical order it would go 1 10 11, you know so forth and so on So I want it to be at least three digits. So if we run that out Only takes a few seconds we can now list out and you can see that we have all our images Starting with image zero zero one image zero zero two and if we look at the thumbnails for those You can see they're all either fully black or fully white images So if we were to pin them all together in a straight line, they would equal a barcode but right now each image is 1080p which is kind of big and So you'll get a really large number in fact if you're going to use image magic to Create that image to append them all it's going to tell you that it's too big So we don't need it any bigger than one by one pixel, which was what my hint in the video was so we could resize Resize so I'm going to do is you're going to create a for loop And I'm going to loop through every PNG in this folder and I'm going to use convert Which part of the image magic package and I'm going to resize them all to one by one pixels And then we're just going to overwrite the original file So we do that it'll take four or five seconds here There we go now if we go back into our file manager here here's the original video you can barely see here They're now one pixel so that's either going to be white You're not going to see anything or you might see a little dot like there and they are not even that Sure, that's gonna pick up in this recording, but that's all we need So now we're just going to use the image magic package again And we're going to say convert plus append if you did dash append they would Append all the images Vertically, but we want them horizontally And so we're going to say convert plus append every PNG and I'm going to output it as a JPEG Just so I can keep my individual frames and the final frame separate just by giving them different extensions So I'll run that doesn't take very long because it's very very small because each image even though there's 347 of them they're all one pixel each now If I was to display out that 100 dot JPEG you can barely see it here, but that is a barcode I can stretch it out here a little bit and you can see it a little bit better But all we need is one pixel high. So it's one pixel high and I guess 347 wide So now we can use Z bar IMG Give it that file and it will give us the link to our hidden video and if we go there You can see The list of people who made it Before I did this this little example video solution video so go ahead and give props to each one of these guys who made it on their own just to shout out to them and Yeah, so I really thought this one might be more difficult But a lot of people made it so we'll see what happens with the next one the next one We'll see what happens They're gonna progressively probably get a little bit harder and I might stop giving hints in some cases, but we'll see I Thank you for watching.
