A media permissions dictionary controls restrictions on how media content may be accessed and played back. The TF entry specifies whether and how the media player may write temporary files when playing the media.

Temporary file controls are important for media that a player must decompress or pre-process before display. The permissions dictionary allows authors to restrict this behaviour for security or licensing reasons.
