1### ► Play Videos plugin for Shaarli
2This plugin adds a `► Play Videos` button to [Shaarli](https://github.com/shaarli/Shaarli)'s toolbar. Click this button to play all videos on the page in an overlay HTML5 player. Nice for continuous stream of music, documentaries, talks...
3
4This uses code from https://zaius.github.io/youtube_playlist/ and is currently only compatible with Youtube videos.
5
6![](https://cdn.mediacru.sh/D_izf0zjAtxy.png)
7
8#### Installation and setup
9Place the files in the `tpl/plugins/playvideos/` directory of your Shaarli.
10This is a default Shaarli plugin, you just have to enable it.
11
12To enable the plugin, add `playvideos` to the `TOOLBAR_PLUGINS` config option in your `index.php` or `data/options.php`. Example:
13
14 $GLOBALS['config']['TOOLBAR_PLUGINS'] = array('aplugins', 'anotherone', 'playvideos');
15
16#### Troubleshooting
17If your server has [Content Security Policy](http://content-security-policy.com/) headers enabled, this may prevent the script from loading fully. You should relax the CSP in your server settings. Example CSP rule for apache2:
18`Header set Content-Security-Policy "script-src 'self' 'unsafe-inline' https://www.youtube.com https://s.ytimg.com 'unsafe-eval'"`
