# VTFrameProcessorConfiguration

A protocol that describes the configuration of a processor to use during a video processing session.

```
protocol VTFrameProcessorConfiguration : NSObjectProtocol, Sendable
```

## Overview

The VTFrameProcessorConfiguration protocol conformance starts a frame processing session. These properties can be queried on an implementation conforming to this protocol without starting a session.

## Topics

### Determining processor availability

[`supported`](/documentation/VideoToolbox/VTFrameProcessorConfiguration/isSupported)

A Boolean value that indicates whether the current configuration supports the processor.

### Inspecting dimension constraints

[`maximumDimensions`](/documentation/VideoToolbox/VTFrameProcessorConfiguration/maximumDimensions-4vmra)

The maximum dimensions of a source frame for the processor.

[`minimumDimensions`](/documentation/VideoToolbox/VTFrameProcessorConfiguration/minimumDimensions-42b0h)

The minimum dimensions of a source frame for the processor.

### Inspecting pixel buffer attributes

[`sourcePixelBufferAttributes`](/documentation/VideoToolbox/VTFrameProcessorConfiguration/sourcePixelBufferAttributes)

A dictionary of pixel buffer attributes that define what the source and reference frames passed to the processor must conform to.

[`destinationPixelBufferAttributes`](/documentation/VideoToolbox/VTFrameProcessorConfiguration/destinationPixelBufferAttributes)

A dictionary of pixel buffer attributes that define which output frames passed to the processor must conform to.

[`frameSupportedPixelFormats`](/documentation/VideoToolbox/VTFrameProcessorConfiguration/frameSupportedPixelFormats)

A list of supported pixel formats for the current configuration.

### Inspecting frame requirements

[`nextFrameCount`](/documentation/VideoToolbox/VTFrameProcessorConfiguration/nextFrameCount-18e47)

The number of next frames that the processor requires for processing.

[`previousFrameCount`](/documentation/VideoToolbox/VTFrameProcessorConfiguration/previousFrameCount-1crhc)

The number of previous frames that the processor requires for processing.
