Prerequisites

The scripts were tested and developed for Python 3.7.

  • Download Browsermob Proxy v. 2.1.4 and place in Data/Libraries/browsermob-proxy-2.1.4
  • Install Chrome
  • Download Chromedriver and place in Data/Libraries/chromedriver
  • (Optional) Obtain the YouTube Adblocker via the chrome store an and place it in Data/Libraries/AdBlock_YouTube.crx
  • Install the python packages needed via requirements.txt

Example

You can find an example of how to use the scripts in "SampleExample.py"
