You almost had me look up all the possible yoga moves and try to get a hidden message from that until I noticed that little flicker at the edge of the screen

Code: Select all
mplayer ../a.mp4 -vf crop=30:50:5:15 -vo png
After that I used imagemagick to beef the contrast of the frames up a bit and had them shown to me in 8-column rows (to confirm they could be ascii). Then I just typed them all in by hand, it wasn't really worth figuring out how to automate that.

I used ImageMagick:
convert a.mp4 c.png
mogrify -crop 50x70+0+0 -colorspace gray c.png
Then looked at a 3x3 square and alternated the bit if there was a difference in brightness.
Luckily my first decoded message was:
the answer t?ߋhis chaS?????ߖ??'asana'?ou????????%
Now I should try to optimize my code
EDIT: PNG not JPEG

Hi,
after transforming the vid to jpegs it took me around 8 mins to type the bits ... so doing that by hand is probably the fastest way ... unless you have a nice pattern-recognition software already installed.

I did it by hand... just stepping frame by frame in the browser.

Yep, its just left/right-arrows in Quicktime. I did it simultaneously with laptop and PC to prevent switching apps.

Ouch, must have hurt in the knees. You're just too tall!
Btw: is this supposed to be a kind of advanced version of Mayurasana? I myself don't even come into the starting position of this... tried Kakasana several times but find it quite difficult.

I also did it with Quicktime... and especially liked the unfinished "ommmmmmmm" at the end

hahaha, I got 414 frames, which is not divisible by 8... luckily, the answer was in the middle of the sentence.

Obviously, there should have been some hot chick in the video, then nobody would have noticed the data
