edx-val (Video Abstraction Layer)

=================================

edx-val is a django app that creates and retrieves metadata for videos and subtitles. When creating video entries, they can be assigned to preset profiles such as 'high_quality' or 'mobile_only'. When requesting a video, the client does not need to know which profile to retrieve, but only the `edx_video_id` of that video. Since all the different profiles for that particular video is returned, the client can decide which profiles they want to use. 

 

Example:

Retrieve all profiles for a video with `edx_video_id`="example"

.. code-block:: python

    >>> get_video_info("example")

    {

        'url' : '/edxval/videos/example',

        'edx_video_id': u'example',

        'duration': 111.0,

        'client_video_id': u'The example video',

        'encoded_videos': [

            {

                'url': u'http://www.example.com/example_mobile_video.mp4',

                'file_size': 25556,

                'bitrate': 9600,

                'profile': u'mobile'

            },

            {

                'url': u'http://www.example.com/example_desktop_video.mp4',

                'file_size': 43096734,

                'bitrate': 64000,

                'profile': u'desktop'

            }

        ]

    }
