[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 .

常量	值	描述
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

该枚举在 Qt 6.7 引入。
