Multiplayer - a multi-stream HTML5 video player

This player plays multiple streams in parallel with a single set of controls. It has been tested with up to 4 streams but should in principle be able to handle an arbitrary number for streams.

The player uses a simple json format to bundle several streams along with some metadata. The format is exemplified in packagedef.json. Such a bundle is usually referred to as a "presentation".

There is also support for playlists, which are also specified in json format. That format is exemplified in listdef.json

Online playback

When playing back presentations online, index.html should be called with the following GET parameters:

• presentation: The ID of a presentation package available on the same web server under /presentation/<ID>

  Allowed aliases for this parameter: play, show, p and s

• playlist (optional): The ID of a playlist package available on the same web server under /playlist/<ID>

  Allowed aliases for this parameter are list and l

Offline playback

The intended use for offline playback is to enable a download feature in a video portal. When playing pack a presentation offline (using files stored on the local machine), dlplayer.html should be used instead of index.html.

The downloaded package should contain:

• dlplayer.html: This is a version of index.html that includes all support files in-line to reduce the number of files for the downloading user to deal with.

  In order for the file to point to the correct presentation data, there is a line that looks like this: localPresentation = %PACKAGE%

  When preparing a download package, the preparing script should replace %PACKAGE% with the json package data relating to the presentation to be downloaded.

• A subdirectory containing the media files

  The paths in the json package data should be relative to dlplayer.html.

Offline playback doesn't support playlists.

Other parameters

There are a few GET parameters that are respected but don't neatly fit into the above:

• debug: Disables automatic prefixing of presentation and playlist paths. Useful when testing and the /presentation or /playlist context paths are unavailable.

• more: Displays a small down arrow in the middle of the video control bar. Only exists so that it will be more obvious that there is more content to see below the presentation when playing in the play platform.
