cropping from an image inside a memory buffer. The application could
configure a capture device to fill only a part of an image by abusing
V4L2 API. Cropping a smaller image from a larger one is achieved by
setting the field struct
:ref:`v4l2_pix_format <v4l2-pix-format>```::bytesperline``.
Introducing an image offsets could be done by modifying field struct
:ref:`v4l2_buffer <v4l2-buffer>```::m_userptr`` before calling

Introducing an image offsets could be done by modifying field ``m_userptr``
at struct

:ref:`VIDIOC_QBUF`. Those operations should be avoided because they are not
portable (endianness), and do not work for macroblock and Bayer formats
and mmap buffers. The selection API deals with configuration of buffer
