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.

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 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

QCameraFormat::QCameraFormat(const QCameraFormat &other)

Copy constructs a camera format from the other format.


Constructs a null camera format.

See also isNull().

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

Assign other to this.


Destructs the camera format object.

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.

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

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