# releaseFrame(_:)

Release a decoded frame when the encoder extension no longer needs the frame.

## Declaration

```swift
func releaseFrame(_ frame: IOSurface!)
```

## Parameters

- `frame`: The decoded frame to release.

## Discussion

Discussion Use the releaseFrame: method to release a frame that the extension obtains by using the copyFrame: method and to notify the decoder that the encoder extension no longer needs the frame. When you use the Objective-C manual reference-counting implementation, call the releaseFrame: method before the frame release call to insure the releaseFrame: method receives a valid frame.
