SponsorBlock

3rd-Party Ports: MPV | Kodi | Safari for MacOS | Chromecast | iOS

SponsorBlock is an open-source crowdsourced browser extension to skip sponsor segments in YouTube videos. Users submit when a sponsor happens from the extension, and the extension automatically skips sponsors it knows about. It also supports skipping other categories, such as intros, outros and reminders to subscribe.

It also supports Invidio.us.

Server

The backend server code is available here: https://github.com/ajayyy/SponsorBlockServer

It is a simple SQLite database that will hold all the timing data.

To make sure that this project doesn't die, I have made the database publicly downloadable at https://sponsor.ajay.app/database.db (License). If you are planning on using the database in another project, please read the API Docs page for more information.

The dataset and API are now being used in some ports as well as a neural network.

A previous project attempted to create a neural network to predict when sponsored segments happen. That project is sadly abandoned now, so I have decided to attempt to revive this idea starting from a crowd-sourced system instead.

API

Building

Rename config.json.example to config.json and adjust configuration as desired.

There are also other build scripts available. Install npm, then run npm install in the repository to install dependencies.

Run npm run build to generate a Chrome extension.

Use npm run build:firefox to generate a Firefox extension.

The result is in dist. This can be loaded as an unpacked extension

Developing with a clean profile

Run npm run dev to run the extension using a clean browser profile with hot reloading. Use npm run dev:firefox for Firefox. This uses web-ext run.
Known chromium bug: Extension is not loaded properly on first start. Visit chrome://extensions/ and reload the extension.

Attribution Generation

If you contribute and add a dependency, update the attribution file using the following steps:

Make sure the attribution generator is installed: npm i -g oss-attribution-generator

generate-attribution
mv ./oss-attribution/attribution.txt ./public/oss-attribution/attribution.txt
