GitLocker: The Coding Marketplace

Description:

blurring 0.2.0

I use a simple template match to find the secret spots in the video. So this is
nothing for a dynamical video. It should be used to clean up for screen records.

Why
Blurring is designed to expand Watch me Coding.
I take my screen in time lapse. One second, one frame. That’s 3600 frames for
an hour. An 8-hour coding day would be 28800 frames. I do not want to search
for secret information in every single frame. I know my secret passwords so I
can scan the video and blur them.

Install
Simple as always. Do not forget to use a virtual environment:
>>> pip install blurring

How to uses
Create a template. You can use any image. Maybe something created with gimp. Or
us supplied tool “blurring-t” (I know that is a ugly name, sorry):
>>> blurring-t template
text [PASSWORD]: PASSWORD
height [18]: 18
...
Before you blur the video, checkout the original.

Now blur it. I use the offset to blur the password before it is completely
visible:
blurring video.mp4 blurred.mp4 template.png --offset 60
This is the result.

And this would be the result without the offset.

There is still something to improve, but for now I am happy.

Watch me coding integration
This is also a plugin for watch me encoding. After you have installed Blurring,
there is an additional command:
>>> wmc -H
info v0.3.3 - Print some infos
link v0.3.3 - Concat all videos to one
record v0.3.3 - Start the record
setup v0.3.3 - Setup the project
blurring v0.1.0 - Blur the final video
First create the final video:
>>> wmc link
Now create the template(s):
>>> mkdir templates
>>> blurring-t templates/dummy
text [PASSWORD]: PASSWORD
height [18]: 18
width [70]: 70
scale [0.4]: 0.4
font [0]: 0
pos_x [0]: 0
pos_y [12]: 12
It is time to blurring out the “PASSWORD”:
>>> wmc blurring
Now you have the video “full_blur.mp4”. Enjoy it.
