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.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property maxFrameRateᅟ: 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:

maxFrameRate()

property minFrameRateᅟ: float¶

Returns the lowest frame rate defined by this format.

Access functions:

minFrameRate()

property pixelFormatᅟ: QVideoFrameFormat.PixelFormat¶

Returns the pixel format.

Most commonly this is either Format_Jpeg or QVideoFrameFormat::Format_YUVY but other formats could also be supported by the camera.
