The Codec List profile is used to store precedence and purge lists of video codec MIME subtypes. When configuring precedenceListItems and purgeListItems attributes, the following rules apply:

  1. A precedence or purge list cannot contain duplicate entries.
  2. A precedence or purge list cannot contain a space character.
  3. Duplicate entries are not allowed within a precedence and purge list for the same Codec List Profile.
  4. A purge list cannot contain the list special character, or asterisk (*).

Command Syntax

	precedenceListItems <comma-separated list of MIME subtypes, or "*" for all>
	purgeListItems <comma-separated list of MIME subtypes>
