# isReadyForMoreMediaData

A Boolean value that indicates whether the receiver is able to accept more sample buffers.

## Declaration

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

## Discussion

Discussion An object conforming to AVQueuedSampleBufferRendering keeps track of the occupancy levels of its internal queues for the benefit of clients that enqueue sample buffers from non-real-time sources, for example, clients that can supply sample buffers faster than they are consumed, and so need to decide when to hold back. Clients enqueueing sample buffers from non-real-time sources may hold off from generating or obtaining more sample buffers to enqueue when the value of readyForMoreMediaData is NO. It is safe to call enqueue(_:) when readyForMoreMediaData is NO, but don’t enqueue sample buffers without bound. To help with control of the non-real-time supply of sample buffers, clients can call requestMediaDataWhenReady(on:using:) in order to specify a block that the receiver should invoke whenever it’s ready for sample buffers to be appended. The value of readyForMoreMediaData often changes` from NO to YES asynchronously, as previously supplied sample buffers are decoded and rendered. This property is not key-value observable.
