Italian guy
dont think has something to do with the riddle..

[Gatekeeper]

im so out of ideas lol
I even turned the numbers 2147129 into letters "badgabi" which can make "dig abba" and in 1980 Abba released album Super Trooper, main song on album was Winner Takes It All and was released in July 1980. But then just more dead ends.

lol its funny the things you end up doing when stuck and what you end up looking at. Brain fried now i'm afraid, mentally tired.

Holy crap, that's a freaky website...

None the less it looks like a game....

HAHAHAHAHAHAAHAH

check this out

[Prospero]

searched for geeky things that happened on july 2, 1980 and so far only found that was the release date for the movie Airplane!

Yeap, Leonardo has nothing to do with arts either  

Have you actually visited the site before turning it down?

[Timmmaahh]

well i'm off for some brain break .. sleep

maybe we'll get some hints tomorrow from OP

edit: awwww... OP is online

[Mitchell]

I am off as well. This puzzle is getting way to hard for my brain to handle.
Goodnight everyone!

so you only checked  '2 1 4 7 1 2 9'. it can also be split into '21 4 7 12 9', '2, 14, 7, 1, 2, 9', etc. i think i checked all of them though.

No more hints, this is the final step....

Can you guys check for coordinates on that pls?
Sorry I am using the phone

probably unrelated but an 8bit game: http://8081netlabel.ru/news/dendycompo_ii/2014-02-09-118

OP, what up with the Russian 8Bit video games?

I do speak a bit of Russian just so I know

There's definitely some kind of file/data embedded in Space.mp4, with ffmpeg, I can do:

Code:

ffmpeg -i Space.mp4 -c:a copy -c:v copy out.mp4

and out.mp4 will be about 2.1mb smaller, even though it contains the same two streams.

Code:

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Space.mp4':
  Metadata:
    major_brand     : mp42
    minor_version   : 0
    compatible_brands: isommp42
    creation_time   : 2014-02-25 11:26:52
  Duration: 00:02:48.21, start: 0.000000, bitrate: 444 kb/s
    Stream #0:0(und): Video: h264 (Constrained Baseline) (avc1 / 0x31637661), yuv420p, 640x360 [SAR 1281:1280 DAR 427:240], 244 kb/s, 29.97 fps, 29.97 tbr, 30k tbn, 59.94 tbc (default)
    Metadata:
      handler_name    : VideoHandler
    Stream #0:1(und): Audio: aac (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 95 kb/s (default)
    Metadata:
      creation_time   : 2014-02-25 11:26:56
      handler_name    : IsoMedia File Produced by Google, 5-11-2011

In addition, I think I found the original copy of the video file (before extra data was embedded into it):

Code:

youtube-dl --format 18 https://www.youtube.com/watch?v=3rysbn9bZ54

This file contains the same video and audio streams found in Space.mp4. If extract using ffmpeg:

Code:

ffmpeg -i Space.mp4 -c:a copy -c:v copy a.mp4
ffmpeg -i Laffe\ the\ Fox\ -\ Left\ Alone\ in\ Outer\ Space-3rysbn9bZ54.mp4 -c:a copy -c:v copy b.mp4
sha256sum a.mp4 b.mp4

I get:

Code:

37f60f1717c142e15baec5a429a0ff07ed1d6efe122a06a15a77228170ed051f  a.mp4
37f60f1717c142e15baec5a429a0ff07ed1d6efe122a06a15a77228170ed051f  b.mp4

So I'm pretty sure that it's the original file before extra data was embedded.

So, now the interesting part, let's check the size in bytes of Space.mp4 and the original from YouTube:

Code:

du -b Space.mp4
9356135	Space.mp4
du -b Laffe\ the\ Fox\ -\ Left\ Alone\ in\ Outer\ Space-3rysbn9bZ54.mp4
7209006	Laffe the Fox - Left Alone in Outer Space-3rysbn9bZ54.mp4

9356135-7209006 = 2147129, which is the number found in Number.txt

So, there are 2147129 bytes of additional data besides the audio and video streams in Space.mp4


Edit: extract the extra data with this:

Code:

dd bs=1 skip=7209006 if=Space.mp4 of=binary

The sha256sum of the extra data is cbd47112ad2b9f3661e6506c7999afabd0f468b3a4acec81e0618ef98cb24bf3

[arg]

So, there are 2147129 bytes of additional data besides the audio and video streams in Space.mp4

Yep. That's exactly the path I took.

Code:

8057685995569da18a15912e754e1510181acb8cad31dfcabb9cab367245be2b = sha256("there's a bunch of data at the end of the file I can't identify. the data is uniform and random, so it's almost certainly encrypted.")

Looking at the split binary a bit deeper we get:

Code:

 $ ent split
Entropy = 7.999908 bits per byte.

Optimum compression would reduce the size
of this 2147129 byte file by 0 percent.

Chi square distribution for 2147129 samples is 273.12, and randomly
would exceed this value 20.80 percent of the times.

Arithmetic mean value of data bytes is 127.4944 (127.5 = random).
Monte Carlo value for Pi is 3.140655128 (error 0.03 percent).
Serial correlation coefficient is -0.001094 (totally uncorrelated = 0.0).

Maybe file can help us out?

Code:

 $ file split.bin
split.bin: data

It's encrypted, whatever it is. However it's not the right size to be any block cipher I know of.

Code:

split.bin https://mega.co.nz/#!SF9m0I5R!xOlTLH6-f8DujD92CYNTt1lpunXWn3pikcLV1ZPXVk4

good find!
