# TwitchAdSolutions

This repo aims to provide multiple solutions for blocking Twitch ads.

## Current solutions

- dyn-skip ([ublock](https://github.com/pixeltris/TwitchAdSolutions/raw/master/dyn-skip/dyn-skip-ublock-origin.js) / [userscript](https://github.com/pixeltris/TwitchAdSolutions/raw/master/dyn-skip/dyn-skip.user.js))
  - Notifies Twitch that ads were watched before requesting the main live stream.
  - May slightly slow down loading of streams.
  - Falls back to mute-black if this fails (use an alternative solution if it always fails for you, as it adds additional load).
  - **Currently only handles pre-rolls** (mid-roll ads should be muted/blacked out) (mid-rolls will require a player reload, which currently isn't implemented)
- dyn-skip-midroll ([ublock](https://github.com/pixeltris/TwitchAdSolutions/raw/master/dyn-skip-midroll/dyn-skip-midroll-ublock-origin.js) / [userscript](https://github.com/pixeltris/TwitchAdSolutions/raw/master/dyn-skip-midroll/dyn-skip-midroll.user.js))
  - The same as `dyn-skip`, but also skips midroll ads (experimental/untested).
  - This requires the script to work perfectly, otherwise the player will hit a reload loop.
- dyn-video-swap ([ublock](https://github.com/pixeltris/TwitchAdSolutions/raw/master/dyn-video-swap/dyn-video-swap-ublock-origin.js) / [userscript](https://github.com/pixeltris/TwitchAdSolutions/raw/master/dyn-video-swap/dyn-video-swap.user.js))
  - Ads are replaced by a low resolution stream for the duration of the ad.
  - Similar to `dyn`, but skips closer to 20 seconds when switching to the live stream.
  - You might see tiny bits of the ad.
  - Audio controls wont work whilst the ad is playing.
- dyn ([ublock](https://github.com/pixeltris/TwitchAdSolutions/raw/master/dyn/dyn-ublock-origin.js) / [userscript](https://github.com/pixeltris/TwitchAdSolutions/raw/master/dyn/dyn.user.js))
  - Ad segments are replaced by low resolution stream segments (on a m3u8 level).
  - Skips 2-3 seconds when switching to the live stream.
  - Stuttering and looping of segments often occur (during the ad segments).
  - **NOTE: Removing segments doesn't notify Twitch that ads were watched (aka more served ads).**
- low-res ([ublock](https://github.com/pixeltris/TwitchAdSolutions/raw/master/low-res/low-res-ublock-origin.js) / [userscript](https://github.com/pixeltris/TwitchAdSolutions/raw/master/low-res/low-res.user.js))
  - No ads.
  - The stream is 480p for the duration of the stream.
- mute-black ([ublock](https://github.com/pixeltris/TwitchAdSolutions/raw/master/mute-black/mute-black-ublock-origin.js) / [userscript](https://github.com/pixeltris/TwitchAdSolutions/raw/master/mute-black/mute-black.user.js))
  - Ads are muted / blacked out for the duration of the ad.
  - You might see tiny bits of the ad.
- proxy-m3u8 ([ublock](https://github.com/pixeltris/TwitchAdSolutions/raw/master/proxy-m3u8/proxy-m3u8-ublock-origin.js) / [userscript](https://github.com/pixeltris/TwitchAdSolutions/raw/master/proxy-m3u8/proxy-m3u8.user.js))
  - Uses a proxy server (set to one controlled by @ChoosenEye) to fetch an ad-free stream.
  - Currently only the initial m3u8 is proxied, so there shouldn't be any additional latency.
  - **Assumes the proxy server acts in good faith and maintains a good uptime.**
  - **The current proxy owner doesn't like the url being used by this project, an alternative host would be ideal.** (requires a web server hosted in a non-ad country, taking a channel name as the last url arg, and fetching the m3u8).

## Applying a solution (uBlock Origin)

uBlock Origin solutions are single files, suffixed by `ublock-origin.js` e.g. `low-res-ublock-origin.js`.

- Navigate to the uBlock Origin Dashboard (the extension options)
- Under the `My filters` tab add `twitch.tv##+js(twitch-videoad)`.
- Under the `Settings` tab, enable `I am an advanced user`, then click the cog that appears. Modify the value of `userResourcesLocation` from `unset` to the full url of the solution you wish to use (if a url is already in use, add a space after the existing url). e.g. `userResourcesLocation https://raw.githubusercontent.com/pixeltris/TwitchAdSolutions/master/dyn/dyn-ublock-origin.js` 

## Applying a solution (userscript)

Tampermonkey / Greasemonkey can be used on the files suffixed by `user.js` e.g. `low-res.user.js`

- Viewing one of the userscript files should prompt the given script to be added
