## Detailed Description

## Type Documentation

### `[since 6.7]` enum class QtVideo::Rotation

The angle of the clockwise rotation that should be applied to a video frame before displaying. The rotation is performed in video coordinates, where the Y-axis points downwards on the display. It means that the rotation direction complies with QTransform::rotate.

Constant | Value | Description
--- | --- | ---
`QtVideo::Rotation::None` | `0` | No rotation required, the frame has correct orientation
`QtVideo::Rotation::Clockwise90` | `90` | The frame should be rotated clockwise by 90 degrees
`QtVideo::Rotation::Clockwise180` | `180` | The frame should be rotated clockwise by 180 degrees
`QtVideo::Rotation::Clockwise270` | `270` | The frame should be rotated clockwise by 270 degrees

This enum was introduced in Qt 6.7.
