# MERAWProcessorPixelBufferManager

Describes pixel buffer requirements and creates new pixel buffers.

```
class MERAWProcessorPixelBufferManager
```

## Discussion

It contains the interfaces that the [`MERAWProcessor`](/documentation/MediaExtension/MERAWProcessor) uses for two tasks. First, to declare its set of requirements for output <doc://com.apple.documentation/documentation/CoreVideo/cvpixelbuffer-q2e> in the form of a [`pixelBufferAttributes`](/documentation/MediaExtension/MERAWProcessorPixelBufferManager/pixelBufferAttributes-2cki6) dictionary. Second, create pixel buffers that match processor output requirements and satisfy Video Toolbox and client requirements.

## Topics

### Creating a pixel buffer

[`pixelBufferAttributes`](/documentation/MediaExtension/MERAWProcessorPixelBufferManager/pixelBufferAttributes-2cki6)

A dictionary that contains the attributes Video Toolbox uses to create a pixel buffer for the video RAW processor.

[`pixelBufferAttributes`](/documentation/MediaExtension/MERAWProcessorPixelBufferManager/pixelBufferAttributes-4fe69)

A dictionary that contains the attributes Video Toolbox uses to create a pixel buffer for the video RAW processor.

[`-  createPixelBufferAndReturnError:`](/documentation/MediaExtension/MERAWProcessorPixelBufferManager/makePixelBuffer())

Generates a pixel buffer using the session’s pixel buffer pool.
