# indicatesNonRectilinearProjection

A media characteristic that indicates the video track carries information related to how it should be projected for display.

```
static let indicatesNonRectilinearProjection: AVMediaCharacteristic
```

## Discussion

This media characteristic is currently synthesized if the CMVideoFormatDescription specifies a non-rectilinear projection. To determine which kind of projection is indicated, look for the format description extension with key kCMFormatDescriptionExtension_ProjectionKind.
The value of this characteristic is @“public.indicates-non-rectilinear-projection”.
Note for content authors: the presence of this characteristic is strictly inferred from the format description of the associated track.
