Function CVPixelBufferGetBaseAddress 

pub extern "C-unwind" fn CVPixelBufferGetBaseAddress(
    pixel_buffer: &CVPixelBuffer,
) -> *mut c_void

Available on crate features CVBuffer and CVImageBuffer and CVPixelBuffer only.

Returns the base address of the PixelBuffer.

Retrieving the base address for a PixelBuffer requires that the buffer base address be locked via a successful call to CVPixelBufferLockBaseAddress.

Parameter pixelBuffer: Target PixelBuffer.

Returns: Base address of the pixels. For chunky buffers, this will return a pointer to the pixel at 0,0 in the buffer For planar buffers this will return a pointer to a PlanarComponentInfo struct (defined in QuickTime).
