CVPixelBufferGetBaseAddressOfPlane(_:_:)

Declaration

func CVPixelBufferGetBaseAddressOfPlane(_ pixelBuffer: CVPixelBuffer, _ planeIndex: Int) -> UnsafeMutableRawPointer?

Parameters

• pixelBuffer:

  The pixel buffer containing the plane whose base address you want to obtain.

• planeIndex:

  The index of the plane.

Return Value

The base address of the plane, or NULL for nonplanar pixel buffers.

Discussion

Retrieving the base address for a pixel buffer requires that the buffer base address be locked using the CVPixelBufferLockBaseAddress(_:_:) function.
