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.

Member Function Documentation

QCameraFormat::QCameraFormat(const QCameraFormat &other)

Copy constructs a camera format from the other format.

QCameraFormat::QCameraFormat()

Constructs a null camera format.

See also isNull().

QCameraFormat &QCameraFormat::operator=(const QCameraFormat &other)

Assign other to this.

QCameraFormat::~QCameraFormat()

Destructs the camera format object.

bool QCameraFormat::isNull() const

Returns true if this is a default constructed QCameraFormat.

float QCameraFormat::maxFrameRate() const

Returns 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.

Note: Getter function for property maxFrameRate.

float QCameraFormat::minFrameRate() const

Returns the lowest frame rate defined by this format.

Note: Getter function for property minFrameRate.

QVideoFrameFormat::PixelFormat QCameraFormat::pixelFormat() const

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.

Note: Getter function for property pixelFormat.

See also QVideoFrameFormat::PixelFormat.

QSize QCameraFormat::resolution() const

Returns the resolution.

Note: Getter function for property resolution.

bool QCameraFormat::operator!=(const QCameraFormat &other) const

Returns false if the other format is equal to this camera format, otherwise true.

bool QCameraFormat::operator==(const QCameraFormat &other) const

Returns true if the other format is equal to this camera format, otherwise false.
