Extract Text from Subtitle
February 23, 2019
I wanted to create docs for the course I enrolled which would help me for future reference, the course offers subtitle and I don’t wanted to search through subtitle then copy-paste content for docs so I decided to convert those subtitle files into text files and then copy whole text into mkdocs (which is the my reference documentation).
Code:
This file contains hidden or bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To review, open the file in an editor that reveals hidden Unicode characters.
