Hydrant groups manager

Hydrant groups manager lives under /admin. Only users in the group admin_policy_object_editor can access this page. Groups are stored in config/role_mapper_[environment].xml 

One can use RoleControls (lib/role_controls.rb) to add/remove groups or add/remove/mass assign users to a group. RoleControls uses RoleMapper from the hydra-access-controls gem.



Matterhorn modules

Processing pipeline

Hydrant distributing module


Engage player

Engage player is a Flash/Javascript hybrid player split into a gem called hydrant-engage. It is included in Hydrant by inserting partial modules/video_player from the gem. It needs to provide a locals hash with 3 properties e.g. locals: {stream:, mimetype: 'video/x-flv', mediapackaged_id: @video_asset.mediapackage_id}

Engage is dependent on Matterhorn and uses mediapackage_id to pulls information about the streaming video from there.

Streaming servers

Red5 is the streaming server at the moment. Adobe Flash Media Server will replace it.
