# isReadyForMoreMediaData

Indicates the readiness of the processor to accept more sample buffers.

```
var isReadyForMoreMediaData: Bool { get }
```

## Discussion

An [`MERAWProcessor`](/documentation/MediaExtension/MERAWProcessor) operates asynchronously and often has a fixed capacity for buffers in flight in the processor. This property allows the processor to signal to <doc://com.apple.documentation/documentation/VideoToolbox> that its internal buffers are full and cannot accept more samples. The processor must use [`MERAWProcessorReadyForMoreMediaDataDidChangeNotification`](/documentation/MediaExtension/MERAWProcessorReadyForMoreMediaDataDidChangeNotification) to notify Video Toolbox when this property changes.
