Detailed Description
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.
Property Documentation
[read-only] maxFrameRate : const float
Returns the highest frame rate defined by this format.
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 float
Returns the lowest frame rate defined by this format.
Access functions:
| float | minFrameRate() const |
[read-only] pixelFormat : const QVideoFrameFormat::PixelFormat
Returns 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 QSize
Returns the resolution.
Access functions:
| QSize | resolution() const |
Member Function Documentation
[noexcept] QCameraFormat::QCameraFormat()
Constructs a null camera format.
See also isNull().
[noexcept] QCameraFormat::QCameraFormat(const QCameraFormat &other)
Copy constructs a camera format from the other format.
[noexcept] QCameraFormat::~QCameraFormat()
Destructs the camera format object.
[noexcept] bool QCameraFormat::isNull() const
Returns true if this is a default constructed QCameraFormat.
bool QCameraFormat::operator!=(const QCameraFormat &other) const
Returns false if the other format is equal to this camera format, otherwise true.
[noexcept] QCameraFormat &QCameraFormat::operator=(const QCameraFormat &other)
Assign other to this.
bool QCameraFormat::operator==(const QCameraFormat &other) const
Returns true if the other format is equal to this camera format, otherwise false.
