REST - API

All API calls need to use the JSON format.

Most REST operations work as expected. Examples for resource creation are listed on the applications dashboard page.

You can use the API to register a new conference. The conference acronym and the URL of the schedule.xml are required. However folders and access rights need to be setup manually, before you can upload images and videos.

curl -H "CONTENT-TYPE: application/json" -d '{
    "api_key":"4","acronym":"frab123",
    "conference":{
      "recordings_path":"conference/frab123",
      "images_path":"events/frab",
      "slug":"event/frab/frab123",
      "aspect_ratio":"16:9",
      "title":null,
      "schedule_url":"http://progam/schedule.xml"
    }
  }' "http://localhost:3000/api/conferences"

You can add images to an event, like the poster image. The event is identified by its guid and the conference acronym.

curl -H "CONTENT-TYPE: application/json" -d '{
    "api_key":"4",
    "acronym":"frab123",
    "poster_url":"http://koeln.ccc.de/images/chaosknoten_preview.jpg",
    "thumb_url":"http://koeln.ccc.de/images/chaosknoten.jpg",
    "event":{
      "guid":"123",
      "slug":"123",
      "title":"qwerty"
    }
  }' "http://localhost:3000/api/events"

Recordings are added by specifiying the parent events guid, an URL and a filename. The recording length is specified in seconds.

curl -H "CONTENT-TYPE: application/json" -d '{
    "api_key":"4",
    "guid":"123",
    "recording":{
      "original_url":"file:///tmp/123",
      "filename":"some.mp4",
      "folder":"mp4",
      "folder":"video/mp4",
      "size":"12",
      "length":"3600"
      }
  }' "http://localhost:3000/api/recordings"

Download event images again, after event was created.

curl -H "CONTENT-TYPE: application/json" -d '{
    "api_key":"4",
    "guid":"123",
    "poster_url":"http://koeln.ccc.de/images/chaosknoten_preview.jpg",
    "thumb_url":"http://koeln.ccc.de/images/chaosknoten.jpg"
  }' "http://localhost:3000/api/events/download"

Download recordings again, after recording was created.

curl -H "CONTENT-TYPE: application/json" -d '{
    "api_key":"4",
    "guid":"123"
  }' "http://localhost:3000/api/recordings/download"
