+ * The protection system value of the unspecified UUID.
+ * In some cases the system protection ID is not present in the contents or in their
+ * metadata, as encrypted WebM.
+ * This define is used to set the value of the "system_id" field in GstProtectionEvent,
+ * with this value, the application will use an external information to choose which
+ * protection system to use.
+ *
+ * Example: The matroskademux uses this value in the case of encrypted WebM,
+ * the application will choose the appropriate protection system based on the information
+ * received through EME API.

+ * Since: 1.16
