QCameraFormat represents a certain video format supported by a camera device.
The format is a combination of a pixel format, resolution and a range of frame rates.
QCameraFormat objects can be queried from QCameraDevice to inspect the set of supported video formats.
See also QCameraDevice and QCamera.
[read-only] maxFrameRate : const floatReturns the highest frame rate defined by this format.
In 6.2, the camera will always try to use the highest frame rate supported by a certain video format.
Access functions:
| float | maxFrameRate() const |
[read-only] minFrameRate : const floatReturns the lowest frame rate defined by this format.
Access functions:
| float | minFrameRate() const |
[read-only] pixelFormat : const QVideoFrameFormat::PixelFormatReturns the pixel format.
Most commonly this is either QVideoFrameFormat::Format_Jpeg or QVideoFrameFormat::Format_YUVY but other formats could also be supported by the camera.
Access functions:
| QVideoFrameFormat::PixelFormat | pixelFormat() const |
See also QVideoFrameFormat::PixelFormat.
[read-only] resolution : const QSizeReturns the resolution.
Access functions:
| QSize | resolution() const |
Copy constructs a camera format from the other format.
Constructs a null camera format.
See also isNull().
Assign other to this.
Destructs the camera format object.
Returns true if this is a default constructed QCameraFormat.
Returns false if the other format is equal to this camera format, otherwise true.
Returns true if the other format is equal to this camera format, otherwise false.
