The plugins directory now supports videos in readme.txt files. YouTube, Vimeo, and WordPress.com VideoPress videos are supported.
Videos are included using one of two formats.
Shortcode: YouTube, Vimeo, WordPress.com VideoPress
Include a normal looking shortcode anywhere in the readme.txt file.
For YouTube and Vimeo, the shortcode has one unnamed parameter: the video’s URL.
For WordPress.com VideoPress videos, the shortcode has one unnamed parameter: the video’s ID. The shortcode can be copied from the video’s embed menu.
To prevent shortcodes from being parsed, enclose the shortcode in backticks.
Autolink: YouTube, Vimeo
Include a YouTube or Vimeo URL by itself on its own line in the readme.txt file.
The Validator shows the videos too.
NB: Directly including object/embed HTML into the readme.txt file is not supported; the goal of the readme.txt file is to be human readable.
PS: Videos are not currently supported as replacements for screenshot images in the screenshots section. It’s silly that the Plugins Directory doesn’t yet support that 🙂 It’s on the todo.
