kVTCompressionPropertyKey_FieldDetail

Field ordering for encoded interlaced frames.

Declaration

let kVTCompressionPropertyKey_FieldDetail: CFString

Discussion

If a video encoder enforces specific field ordering, this property will be read-only (VTSessionSetProperty(_:key:value:) returns kVTPropertyReadOnlyErr). The field detail is set on the format description for output samples, and may affect source frame scaling. NULL is a valid value for this property.
