# VTFrameProcessorParameters

The base protocol for input and output processing parameters for a frame processor implementation.

## Declaration

```swift
protocol VTFrameProcessorParameters : NSObjectProtocol
```

## Overview

Overview An instance of a class corresponding to this protocol is passed to processWithParameters:error: calls and for asynchronous versions of those calls, the same instance is returned in the completion.

## Topics

### Inspecting the parameters
