Random playback

The SMIL player offers functionality to specify a play mode for a specific playlist in the player's XML definition file. This feature is useful when you want to play content in a random order or randomly pick one element from the specified playlist.

Play modes​

SMIL player supports three types of play modes:

  • random - In every time player reaches segment, the SMIL player shuffles the playlist and plays the whole playlist in a random order. order.

  • random_one - In every time player reaches segment, the SMIL player randomly picks one element from the playlist and plays only that element.

  • one - In every time player reaches segment, the SMIL player plays only one element from the playlist. In the next playback cycle, the SMIL player will pick the element that comes directly after the previous one. This behavior continues until the end of the playlist, after which it will start again from the beginning.

Playlist definition​

Play mode is specified in the playMode attribute of the seq element.
