The YouTube Subtitle Explorer is a tool you can install on your server to provide a website to display videos from one of your youtube playlists. Users can then search by languages to find videos that contain or don’t contain subtitles for a particular language. Users can also easily submit caption files that can be then uploaded directly to youtube which makes maintenance very easy.
As seen on Minute Physics Translate.
Like the software? Why not buy me a coffee? All donations go first towards maintenance of YTSE, then to future open-source projects (and/or coffee).
- Positive and Negative search for videos by one or more subtitles by language name.
- Watch video with specified captions by clicking on a language.
- Google/YouTube OAuth 2 login authentication. Meaning much less likelihood of getting spam submissions.
- “Help Translate” crowdsourcing feature. So anyone can safely submit subtitle files for any of your videos.
- Administration panel that allows you to moderate caption submissions.
- Caption trash archive (to keep past submissions).
- Email notifications for (consenting) contributors and the administrator.
- Automatic Updates! Update feature allows administrator to update the system with the click of a button.
- Ability to (almost) entirely override the look/feel of the site.
- Maintenance mode.
- Webserver with PHP 5.3+, and SQLite 3
- Google account and Youtube Account
- Download the latest source from GitHub
- Extract the zip contents into a folder on your web server.
- If the folder isn’t the root directory, edit the
.htaccessfile contents to point it to the subfolder. (Look for the helpful comments)
- Visit the directory in a browser and follow the instructions (it will tell you to visit
You will need to create your own developer API keys to install this app. You will need a google Project with API OAuth access and a YouTube developer key.
- Visit YouTube’s API Dashboard.
- Click to create a “New Product”
- Enter a name like “YTSE”
- Click save
- Visit google’s api console.
- Create a new project (give it a name you like)
- Click on “API Access”
- Click “Create an OAuth 2.0 client ID…”
- Enter the product name: “YTSE”
- Select Application Type = “Web Application”
- In the “Your site or hostname” section, unless you have a secure site, change the protocol to
httpand enter the url to get to the app. (i.e. if your installation is on example.com in the subfolder translations/, you would enter: example.com/translations/ ). Click Continue.
- You’ll need to click “more options” in order to specify the “Authorized Redirect URIs” field. Specify it as your homepage with the path login/authenticate/callback (eg: if your installation is on http://example.com in the subfolder translations/, the field should end up being: http://example.com/translations/login/authenticate/callback)
SECURITY NOTE: if your system ever becomes comprimised, or you suspect it may be comprimised, the above URLs will allow you to change your client secret and invalidate API keys. This is the first thing you should do if you think someone has hacked your system.
/admin in your web browser to login to the admin panel.
After you have finished installing the app, you can set up email notifications to be sent when you get a new submission. To do this, visit the admin panel and click on the “settings” tab.
.htaccess files with “deny from all” rules in certain sensitive directories. These include:
Whatever you do, ensure that these directories are not accessible by the public and are only accessible by the php application code. (as long as the htaccess files are working that should be taken care of already).
Also, please remember that you shouldn’t share the API keys. If your system ever becomes compromized you can always invalidate the keys through google, and paste any newly created keys into the
If you ever suspect that your system has been compromized (and someone could have downloaded your database), then immediately unauthorize this app from your google authorized applications and websites page.
Once the app is installed, you’ll be notified in the administrator panel if there are updates. Just remember to always backup before updating.
If you have knowledge of HTML/CSS, you can override any of the templates by creating your own in the
/user/views directory. Just name your override the same name as you find it in the
/app/views directory. Don’t change any code in the
/app directory because you will loose those changes if you upgrade.
Views are rendered with the twig templating system. You will need to understand how to write twig templates before you can make any changes.
Creating new templates will let you change almost all markup on the app. This is also how you should include your own css or js files.
Tip: all full-page templates extend the
page-skeleton.twig template. So if you override that one, it’s a great place to place your custom css js includes. Feel free to use your own subdirectories in
/user to hold your custom js/css.
Please feel free to send pull requests my way. Dependencies are entirely managed by composer.
