## Discussion

This property is specific to MV-HEVC.

The entries in the specified array should be in the same order and have the same count as the value specified in [`kVTCompressionPropertyKey_MVHEVCVideoLayerIDs`](/documentation/VideoToolbox/kVTCompressionPropertyKey_MVHEVCVideoLayerIDs).

The default value is `NULL`.
