Discussion

Using SMPTE 291 and SMPTE RDD 18 standards for user-defined data, this property specifies the user-defined ancillary data to be sent with every frame in AVCaptureBroadcastVideoOutput. The dictionary will contain a NSUUID the rdd18InstanceUID key, a uint16_t for the rdd18UDAMSetVersion key and a dictionary for the rdd18UserItems. The rdd18UserItems will contain keys of the user tag and with the corresponding values.

To update the data please see the following methods:

setUserInstanceUID:userUdamVersion: will update the rdd18InstanceUID and rdd18UDAMSetVersion keys
setRDD18AncillaryData(_:forTag:) will update the rdd18UserItems key
setRDD18AncillaryDataString(_:forTag:) will update the rdd18UserItems key
