asbplayer is a browser-based media player and Chrome extension for subtitle sentence mining, hosted at https://killergerbah.github.io/asbplayer/. Use asbplayer to combine subtitles and media extracted from streaming or local video sources to create media-rich Anki flashcards.

If you are a non-English native, and would like to help translate asbplayer, please contact me on Discord.

First, see if you can get started with one of the community guides.

Otherwise, the following steps will work for any language:

1. Install a dictionary for your target language that allows you to do instant lookups. Popular ones are Yomichan for Japanese and VocabSieve for European languages.
2. Install the asbplayer Chrome extension.
3. Install Anki, and create a deck and note type.
4. Install the AnkiConnect plugin for Anki.
5. Configure asbplayer to create cards via AnkiConnect with your deck and note type.
6. Drag-and-drop a subtitle file into the streaming video you want to mine. You may have to adjust the subtitle offset to get the subtitles in sync.
7. When a subtitle appears that you want to mine, use Ctrl+Shift+X to open the Anki dialog.
8. Fill in the definition and word fields and then export the card. To fill in the definition field you may use the dictionary you installed in step 1.

Install the Chrome extension. There are three ways to sync streaming video with asbplayer:

1. Drag-and-drop a subtitle file into the video element you want to sync.
2. Load a file into the asbplayer site and click on the camera in the bottom right to pick a video element to sync. This is the recommended way to load BluRay subtitle files onto streaming video.
3. Use Ctrl+Shift+F to select a video element to sync. From the dialog that appears you can choose whether to load an auto-detected subtitle track or an empty one.

Drag-and-drop media and subtitle files into the asbplayer site to load them.

Make sure Anki and AnkiConnect are installed. Integration with AnkiConnect can be configured in the settings as in this video.

When a subtitle that you want to mine appears, Ctrl+Shift+X opens the Anki export dialog.

All text fields can be edited from the Anki export dialog before exporting the Anki flashcard.

To adjust audio or subtitle selection, adjust the selected time interval for the card using the slider at the bottom of the export dialog. The newly selected time interval can be applied using the buttons in either the sentence or audio fields. See this video for a demo of this.

Ctrl+Left/Right will adjust subtitle offset so that the previous/next subtitle appears at the current timestamp. Ctrl+Shift+Left/Right will adjust offset by 100 ms increments.

You can also adjust offset manually by clicking on the "Subtitle Offset" text field in the controls in the asbplayer tab, typing a number, and pressing Enter.

Ctrl+Shift+F will show detected subtitle tracks for streaming video. Below are the sites where automatic subtitle detection is supported:

• Netflix
• Youtube
• Disney Plus (known issue: subtitles sometimes off by ~5 seconds)
• Hulu
• TVer
• Bandai Channel
• Amazon Prime (known issue: subtitles sometimes off by ~30 seconds)

Ctrl+Shift+F also allows you to choose an empty subtitle track so that you can mine streaming video without subtitles.

An audio track selector will appear for mkv files if experimental web platform features are enabled from chrome:https://flags. Note that enabling this flag may cause issues with other features of asbplayer, such as card creation from streaming sources.

Most keyboard shortcuts shared by the extension and the website are customizable from the asbplayer website settings. These shortcuts can be toggled on and off from the extension popup. Extension-only shortcuts and some shared shortcuts that require special access to Chrome extension features are customizable from chrome:https://extensions/shortcuts.

• Try refreshing both the asbplayer tab and the video in the other tab.
• Make sure that in the extension details, the extension has access to all sites. A lot of video players are loaded inside of iframes, so it's difficult to know every single URL that the extension might need access to.

• Check chrome:https://extensions/shortcuts.
• Check the keyboard shortcut settings from the asbplayer website.
• You can also check the currently-bound shortcuts from the extension popup menu.
• Try uninstalling and reinstalling the extension and restarting Chrome.
• Make sure the extension isn't installed twice.

• See the Keyboard Shortcuts section.

• If you're using Brave, make sure asbplayer isn't being blocked by Shield.
• Make sure that asbplayer is allowed by AnkiConnect, as in this video.
• Check that your browser or an ad blocker isn't blocking the request. A good place to start is by opening your browser's developer console and looking for errors.
• As of this writing enabling experimental web platform features is known to cause this issue. Try disabling this flag from chrome:https://flags.
• On later versions of macOS AnkiConnect will not respond sometimes Anki is in the background. See "Notes for MacOS Users" at the AnkiConnect developer's website.

• See the Browser Compatibility section.

• If you're mining streaming video make sure you use an extension keyboard shortcut (Ctrl+Shift+X by default) from the tab with the streaming video.

• Make sure the browser zoom setting is at 100%.
• You can disable cropping altogether using the extension settings menu.

The asbplayer application and extension have only been tested on the latest version Chrome and likely work on other Chromium-based browsers.

Local video file playback is supported only for codecs supported by the browser. The animebook readme has a detailed explanation of this and links to browsers that have good compatibility. Personally, I use Microsoft Edge and paid one dollar for HEVC support.

Pull requests are welcome! However, to reduce back-and-forth during review ideally consult with me on the corresponding issue or on Discord before attempting changes to UI/UX. When making changes, format code according to the Prettier config and attempt to match the style of surrounding code.

# Install yarn
npm install --global yarn

# Make sure you're on yarn 3
yarn set version 3.2.0

# Install dependencies
yarn

# Starts the development server for the website
yarn workspace @project/client run start

# Build the extension to extension/dist
yarn workspace @project/extension buildDev

If you have problems building try deleting node_modules and re-running yarn.

Submit bugs or feature requests from the issues page. Join the Discord server to talk with me and other language learners.
