You got two options. Either you filter your valid video extentions as @birgire recommended. I remember a similar issue for the audio shortcode here. There I found a workaround by allowing the empty audio extension. You could try something similar with the video extensions. Here’s a demo plugin: /** * Allow the empty video extension … Read more
Indeed, the “Insert video” action does not do much beyond creating a link. WordPress does not contain a generic player that can play any video hosted anywhere on the internet, but it does support something better: embedding via oEmbed. This means you can put the URL of the video page in your content, and it … Read more
First: You will need a plugin that acts as an intermediary for your cloud storage. Cloud storage innately (if setup properly) will protect your files. I have used the CDN Vault plugin and it works great. It’s a premium plugin that depends on Amazon S3 storage. It does some really great obfuscation and encryption so … Read more
Ran into this same issue and I found the answer after many hours and almost giving up. It’s in a bit of code that written to make the Customizer work with playlists. Checkout this comment from /wp-includes/widgets/class-wp-widget-text.php: /** * Enqueue preview scripts. * * These scripts normally are enqueued just-in-time when a playlist shortcode is … Read more

Registering a custom embed handler Here’s an example how we can use the wp_embed_register_handler() function in your case: /** * Register an embed handler for myvi videos */ add_action( ‘init’, function() { wp_embed_register_handler( ‘myvi’, ‘#http://www\.myvi\.ru/watch/([a-zA-Z0-9_-]+)$#i’, // <– Adjust this to your needs! ‘myvi_embed_handler’ ); } ); Here we constructed the regular expression in a way … Read more
filtering the_excerpt() If you remove_filter( ‘get_the_excerpt’, ‘wp_trim_excerpt’ ) and add your own get_the_excerpt filter you can do this. The default filter (wp_trim_excerpt()) can be found on line 2023 of /wp-includes/formatting.php if you want to just modify that. The extent of what you need to do is just modifying which tags are allowed in strip_tags(). overriding … Read more
That width is dictated by the $content_width global, defined by the Theme. To change it, you’ll need to hook into after_setup_theme and modify it: function wpse124075_setup_theme() { global $content_width; if ( ! isset( $content_width ) ) { $content_width = 640; // your value here, in pixels } } add_action( ‘after_setup_theme’, ‘wpse124075_setup_theme’ );
You can filter the HTML output for oEmbed with oembed_result. Now test the HTTP host of the URL for www.youtube.com and add the parameter. The oEmbed result is cached in a post meta field to avoid too many requests. To update old posts I have added an activation helper that clears those cached content for … Read more
