This is a command line utility to strip out in video YouTube advertisements from downloaded YouTube videos, such as those downloaded from youtube-dl. This means that you both don't waste disk space on adverts and don't redistribute adverts. If you want to download and strip a video you can use the wrapper application youtube-dl-sponsorblock which uses youtube-dl to download the video and will then strip the video of sponsors for you.
It makes use of the SponsorBlock API and I'd recommend installing the extension and maybe contributing some sponsorship times when you're ever bored.
You can build youtube-dl-sponsorblock and sponskrub by running dub build, to build only one of them use dub build :youtube-dl-sponsorblock and dub build :sponskrub respectively.
