 Standing in my bathroom and you may ask why and it's not because sound in here is horrible with all the echoing It's because well, I have children on the other end of the house and they're being noisy And I want to record this video right now and normally I go outside for this, but it's hot I live in Florida. Anyway, this is a follow-up video to a video. I posted not too long ago secret message Which was a very simple secret message and we're gonna have a quick look at how to decode that today It was just kind of a barely hidden QR code But definitely I hope to do more videos like that. It's something I've wanted to do for a long time And definitely get a lot more complicated than that one, which was pretty simple. Although, you know Some people might, you know, see things quicker than others So we're gonna look at at decoding that You know basically QR code But there's a few steps to get to that point today in this video But I also hope to do more videos like this. It's not gonna take the place of other videos It's gonna be like every once in a while I'll just make a random video with a secret message and then like a week or so later I'll show you how to solve that secret message and there's no Rewards or prizes usually the end result will link you to a YouTube video where you can comment and say, hey I made it here. Yay, you know Just so you can claim your fame A few things about the first video I posted. First of all, I don't know Maybe you guys don't like this because it had a lot of thumbs down I think there were four currently there are four thumbs up and four thumbs down So half people didn't like this and I don't know why I don't know if it's because it was too hard for them I don't know if it was because it was too easy or they just don't like secret messages But we'll see I like I said, I think about this sort of thing when I'm just out in the bottom like Oh, it'd be cool if I did a secret code like this or a secret code like that and So again, this one was real simple Look at it now, and it'll be more difficult once in the future, but let me know in the comments below Does this sort of thing things seem fun to you? You know my channel is mainly about learning but the second part is about community and just having fun with one Other and I've really over the years tried to get my viewers to be more interactive and There has been a few of you But I thought this would be more thing, you know, we can interact and The only thing I ask and I asked this, you know I had Annotations in the original video and people kind of ignored it is when you get the answer to the video don't post it in the comments Go to the link where it's providing and post your comments there. Don't ruin the fun for other people. Okay? I know me saying that's not gonna help, but let's go ahead and look at decoding That simple qr code now. Okay, so this we're just gonna solve that Simple qr code So first download the YouTube video at the best quality you can I like using YouTube DL But whatever technique you use will be great. So let me go ahead and I'm going to copy and I'm gonna paste in the URL to the video and It shouldn't take long. It's like a 12-second video There we go. So we have that downloaded So next what we want to do is we want to extract a frame from it You could open it up in a video editor like Caden live and then just say extract frame I'm gonna use I'm gonna use ffmpeg because that's what I normally use give it the input of our video So ffmpeg dash I inputted the video dash dash No, just one dash SS 00 colon 00 colon 0 0 actually 0 1 there So what I'm saying here is just go to the first second of the video and we're gonna say v frame One which is the same extract one frame and we're gonna put it output dot png So again ffmpeg and then dash I for the input and we give it the name of the video We just downloaded and then dash SS for you know the second that we want to go to Which it's the same image throughout the entire video. I'm just saying go to one second and extract a Frame just one frame and I'll put it to there hit enter and now if we list you can see that obviously I must have typed something wrong V frame. Oh, sorry. It's v frames with an s There we go So now we have an output PNG which I can display real quick Which right here and if you look close enough you can see that there's qr code in there in fact an image magic here I could probably edit this and and adjust it. I could do that enhancements, so I was gonna go into GIMP because that's what I would normally use Let me just go into GIMP because that's what I was planning on doing But you could use image magic in the GUI there or image magic from the command line to adjust the picture But I'm just gonna say go to GIMP and a lot of the viewers were right You could open this up and you can either Go to colors threshold and it would give you the qr code I haven't tested up people said it worked what I did was I just went to contract Brace and contrast and turn the contrast all the way up because the way I created this image was I Turned the contrast all the way down and then moved it up one one degree, you know So go ahead do that. We'll go ahead and we'll export that and then we will close this So now if I display output.png you can see it's our new image and then I'm going to use Z bar IMG which you can install the package is called Z bar dash tools I've done videos on this before give it an image and we'll find all types of bar codes both qr codes and standard You know standard bar codes like UPCs and stuff We'll go ahead and we'll enter on that and you'll see that it gives you a URL here And then you can go to that URL and comment again I'm going to hopefully do more secret video secret message videos like this just for fun And when you solve them again, don't comment on the secret message comments on how to get there or where it leads Go to the actual video because that's well where it will normally lead or a link on my site or something I don't even know but you can comment after you solve it not on the postings you want to ruin for other people But that is it It's that simple.
