FlashVideo is a complete turn-key video solution that expands Drupal's upload capabilities to allow web developers and users to upload video files, automatically convert those videos to the popular Flash format, and then embed their video in any node type using the simple [video] tag. This module allows more than one video to be attached to any node, and then referenced through the use of parameters passed to the tag [video]. It also includes an automatic conversion of video files to the Flash format using FFMPEG technology.
The OG Public Access module allows Organic Groups (OG) administrators to control public access to their groups' content. This module does not require group administrators to be granted the site-wide administer nodes permission.
The use case for this module is for a site with teams of writers submitting content privately in their groups, and editors controlling what is allowed to go public in specific groups.
This module allows you to add a mathematics filter to your regular input filters. You can then post mathematical equations between [tex] and [/tex] tags.
