Modes for requesting a specific deinterlacing technique.

```

## Discussion

This is an optional property for video decoders to implement. Decoders should only accept the modes that they will implement.

This property is only applicable if [`kVTDecompressionPropertyKey_FieldMode`](/documentation/VideoToolbox/kVTDecompressionPropertyKey_FieldMode) is set to [`kVTDecompressionProperty_FieldMode_DeinterlaceFields`](/documentation/VideoToolbox/kVTDecompressionProperty_FieldMode_DeinterlaceFields).
