Commit and push your changes to github ```sh git commit -m "Awesome description of some awesome changes." git push ``` 11. Open your branch up on the github website then click `New pull request` and write up a description of your changes. ## Optional ### Run Pre-Commit Checks Locally Installing [pre-commit](https://pre-commit.com/) is easy to do (click the link for instructions on your platform). This repo comes with pre-commit already configured. Doing this will ensure that your project is properly formatted and runs some very basic tests. Once you have pre-commit installed on your system, simply enter `pre-commit install` in your terminal in the folder to have these checks run automatically each time you commit. Even better, after issueing the install command you can now manually run pre-commit checks before committing via `pre-commit run --all-files` ### Pull Upstream Changes You should always be working with the latest version of the tool to make pull requests easy. If you want to do this easily, just add a second remote to your local git repo like this `git remote add upstream https://github.com/igrigorik/videospeed.git` Now any time you like to pull the latest version in to your local branch you can simply issue the command `git pull upstream master` ================================================ FILE: LICENSE ================================================ MIT License Copyright (c) 2014 Ilya Grigorik Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the “Software”), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

By contrast, the average rate of speech for English speakers is ~150 wpm, with slide presentations often closer to 100 wpm. As a result, when given the choice, many viewers [speed up video playback to ~1.3\~1.5 its recorded rate](http://research.microsoft.com/en-us/um/redmond/groups/coet/compression/chi99/paper.pdf) to compensate for the difference. Many viewers report that [accelerated viewing keeps their attention longer](http://www.enounce.com/docs/BYUPaper020319.pdf): faster delivery keeps the viewer more engaged with the content. In fact, with a little training many end up watching videos at 2x+ the recorded speed. Some studies report that after being exposed to accelerated playback, [listeners become uncomfortable](http://alumni.media.mit.edu/~barons/html/avios92.html#beasleyalteredspeech) if they are forced to return to normal rate of presentation. ## Faster HTML5 Video HTML5 video provides a native API to accelerate playback of any video. The problem is many players either hide or limit this functionality. For the best results, playback speed adjustments should be easy and frequent to match the pace and content being covered: we don't read at a fixed speed, and similarly, we need an easy way to accelerate the video, slow it down, and quickly rewind the last point to listen to it a few more times. ![Player](https://cloud.githubusercontent.com/assets/2400185/24076745/5723e6ae-0c41-11e7-820c-1d8e814a2888.png) ### _[Install Chrome Extension](https://chrome.google.com/webstore/detail/video-speed-controller/nffaoalbilbmmfgbnbgppjihopabppdk)_ \*\* Once the extension is installed simply navigate to any page that offers HTML5 video ([example](http://www.youtube.com/watch?v=E9FxNzv1Tr8)), and you'll see a speed indicator in top left corner. Hover over the indicator to reveal the controls to accelerate, slowdown, and quickly rewind or advance the video. Or, even better, simply use your keyboard: - **S** - decrease playback speed. - **D** - increase playback speed. - **R** - reset playback speed to 1.0x. - **Z** - rewind video by 10 seconds. - **X** - advance video by 10 seconds. - **G** - toggle between current and user configurable preferred speed. - **V** - show/hide the controller. - **M** - set a marker at the current playback position. - **J** - jump back to the previously set marker. You can customize and reassign the default shortcut keys in the extensions settings page as well as add additional shortcut keys to match your preferences. As an example, you can assign multiple "preferred speed" shortcuts with different values, allowing you to quickly toggle between your most frequently used speeds. To add a new shortcut, open extension settings and click "Add New". After making changes or adding new settings, remember to refresh the video viewing page for them to take effect. ![settings Add New shortcut](https://user-images.githubusercontent.com/121805/50726471-50242200-1172-11e9-902f-0e5958387617.jpg) Unfortunately, some sites may assign other functionality to one of the shortcut keys - this is inevitable. As a workaround, the extension listens both for lower and upper case values (i.e. you can use `Shift-`) if there is other functionality assigned to the lowercase key. This is not a perfect solution since some sites may listen to both, but it works most of the time. ### FAQ **The video controls are not showing up?** This extension is only compatible with HTML5 video. If you don't see the controls showing up, chances are you are viewing a Flash video. If you want to confirm, try right-clicking on the video and inspect the menu: if it mentions flash, then that's the issue. That said, most sites will fallback to HTML5 if they detect that Flash it not available. You can try manually disabling Flash plugin in Chrome: - In a new tab, navigate to `chrome://settings/content/flash` - Disable "Allow sites to run Flash" - Restart your browser and try playing your video again **The speed controls are not showing up for local videos?** To enable playback of local media (e.g. File > Open File), you need to grant additional permissions to the extension. - In a new tab, navigate to `chrome://extensions` - Find "Video Speed Controller" extension in the list and enable "Allow access to file URLs" - Open a new tab and try opening a local file; the controls should show up. ### License (MIT License) - Copyright (c) 2014 Ilya Grigorik ================================================ FILE: manifest.json ================================================ { "name": "Video Speed Controller", "short_name": "videospeed", "version": "0.9.5", "manifest_version": 3, "minimum_chrome_version": "89", "description": "Speed up, slow down, advance and rewind HTML5 audio/video with shortcuts", "homepage_url": "https://github.com/igrigorik/videospeed", "icons": { "16": "assets/icons/icon16.png", "48": "assets/icons/icon48.png", "128": "assets/icons/icon128.png" }, "permissions": [ "storage", "activeTab" ], "background": { "service_worker": "background.js" }, "options_ui": { "page": "ui/options/options.html", "open_in_tab": true }, "action": { "default_icon": { "19": "assets/icons/icon19.png", "38": "assets/icons/icon38.png", "48": "assets/icons/icon48.png" }, "default_popup": "ui/popup/popup.html" }, "content_scripts": [ { "all_frames": true, "matches": [ "http://*/*", "https://*/*", "file:///*" ], "match_about_blank": true, "exclude_matches": [ "https://hangouts.google.com/*", "https://meet.google.com/*" ], "css": [ "styles/inject.css" ], "js": [ "content.js" ] } ], "web_accessible_resources": [ { "resources": [ "inject.js" ], "matches": [ "http://*/*", "https://*/*", "file:///*" ] } ] } ================================================ FILE: package.json ================================================ { "name": "video-speed-controller", "version": "0.8.0", "description": "Speed up, slow down, advance and rewind HTML5 audio/video with shortcuts", "type": "module", "scripts": { "build": "node scripts/build.mjs", "dev": "node scripts/build.mjs --watch", "prebuild": "rm -rf dist", "test": "npm run build && npm run test:unit", "test:unit": "node tests/run-tests.js unit", "test:integration": "node tests/run-tests.js integration", "test:e2e": "npm run build && node tests/e2e/run-e2e.js", "test:browser": "echo 'Open tests/fixtures/test-page.html in browser'", "serve": "python3 -m http.server 8000", "lint": "eslint src/**/*.js tests/**/*.js", "lint:fix": "eslint src/**/*.js tests/**/*.js --fix", "format": "prettier --write src/**/*.js tests/**/*.js", "zip": "npm run build && cd dist && zip -r videospeed.zip . && cd .. && echo 'Extension packaged at dist/videospeed.zip'" }, "devDependencies": { "@eslint/js": "^8.57.0", "esbuild": "^0.25.0", "eslint": "^8.57.0", "fs-extra": "^11.2.0", "globals": "^13.24.0", "jsdom": "^23.0.0", "prettier": "^3.1.0", "puppeteer": "^24.10.2" }, "eslintConfig": { "env": { "browser": true, "es2022": true, "node": true, "webextensions": true }, "extends": [ "eslint:recommended" ], "parserOptions": { "ecmaVersion": 2022, "sourceType": "module" }, "globals": { "chrome": "readonly" }, "rules": { "no-unused-vars": [ "error", { "argsIgnorePattern": "^_" } ], "no-console": "off", "prefer-const": "error", "no-var": "error", "eqeqeq": "error", "curly": "error", "semi": [ "error", "always" ], "quotes": [ "error", "single", { "avoidEscape": true } ] } }, "prettier": { "singleQuote": true, "semi": true, "tabWidth": 2, "trailingComma": "es5", "printWidth": 100 } } ================================================ FILE: scripts/build.mjs ================================================ import esbuild from 'esbuild';

The speed controls are not showing up for local videos or Incognito mode?

To enable playback of local media (e.g. File > Open File) or Incognito mode, you need to manually grant additional permissions to the extension.

  • In a new tab, navigate to chrome://extensions
  • Find "Video Speed Controller" extension in the list and enable "Allow access to file URLs" and/or "Allow in Incognito".

Chrome browser installed 2. Extension loaded in developer mode ## Loading the Extension 1. Open Chrome 2. Go to `chrome://extensions/` 3. Enable "Developer mode" (toggle in top right) 4. Click "Load unpacked" 5. Select the videospeed project directory 6. Verify the extension appears in the list ## Test Cases ### 1. Basic Functionality Test **URL:** https://www.youtube.com/watch?v=gGCJOTvECVQ **Steps:** 1. Navigate to the YouTube URL 2. Wait for video to load 3. Look for the Video Speed Controller overlay (small speed indicator) 4. Verify the controller shows "1.00" initially **Expected Results:** - ✅ Speed controller appears over the video - ✅ Shows current speed (1.00x) - ✅ Controller has +, -, reset, and other buttons ### 2. Speed Control Test **Steps:** 1. Click the "+" (faster) button 2. Observe speed changes to ~1.10 3. Click the "-" (slower) button 4. Observe speed changes to ~1.00 5. Click faster multiple times 6. Click the reset button **Expected Results:** - ✅ Video speed increases with "+" - ✅ Video speed decreases with "-" - ✅ Speed display updates accordingly - ✅ Reset button returns to 1.00x - ✅ Video playback actually speeds up/slows down ### 3. Keyboard Shortcuts Test **Steps:** 1. Focus on the video (click on it) 2. Press 'D' key (faster) 3. Press 'S' key (slower) 4. Press 'R' key (reset) 5. Press 'Z' key (rewind) 6. Press 'X' key (advance) **Expected Results:** - ✅ 'D' increases speed - ✅ 'S' decreases speed - ✅ 'R' resets to 1.00x - ✅ 'Z' rewinds video by ~10 seconds - ✅ 'X' advances video by ~10 seconds ### 4. YouTube Integration Test **Steps:** 1. Pause/play the video using YouTube controls 2. Seek to different positions in the video 3. Change quality settings 4. Verify speed controller remains functional **Expected Results:** - ✅ Speed settings persist through pause/play - ✅ Speed settings persist through seeking - ✅ Controller remains visible and functional - ✅ Speed changes affect actual playback rate ### 5. Settings Persistence Test **Steps:** 1. Set video speed to 1.5x 2. Navigate to another YouTube video 3. Check if speed setting is remembered (depends on settings) **Expected Results:** - ✅ Speed may reset to 1.0x or remember 1.5x (based on extension settings) - ✅ Controller appears on new video - ✅ All functionality works on new video ### 6. Cross-Site Test **Test URLs:** - https://vimeo.com/90509568 - https://developer.mozilla.org/en-US/docs/Web/HTML/Element/video (scroll to examples) **Steps:** 1. Navigate to different video sites 2. Verify controller appears 3. Test speed controls **Expected Results:** - ✅ Controller works on multiple video sites - ✅ All functionality is consistent across sites ## Troubleshooting ### Controller Not Appearing - Check if extension is enabled in chrome://extensions/ - Refresh the page - Check browser console for errors (F12 → Console) ### Speed Not Changing - Verify video is playing (not paused) - Check if site has custom video controls that interfere - Try keyboard shortcuts instead of buttons ### Performance Issues - Lower video quality if needed - Close other tabs to free up resources ## Reporting Results For each test case, note: - ✅ PASS: Feature works as expected - ⚠️ PARTIAL: Feature works but with issues - ❌ FAIL: Feature doesn't work - 🔍 NOTES: Any additional observations ## Expected Final Result All test cases should pass, confirming: 1. Extension loads correctly 2. Video detection works 3. Speed controls function properly 4. Keyboard shortcuts work 5. Settings persist appropriately 6.
