 /**
- * \class V4L2PixelFormat
- * \brief V4L2 pixel format FourCC wrapper
- *
- * The V4L2PixelFormat class describes the pixel format of a V4L2 buffer. It
- * wraps the V4L2 numerical FourCC, and shall be used in all APIs that deal with
- * V4L2 pixel formats. Its purpose is to prevent unintentional confusion of
- * V4L2 and DRM FourCCs in code by catching implicit conversion attempts at
- * compile time.
- *
- * To achieve this goal, construction of a V4L2PixelFormat from an integer value
- * is explicit. To retrieve the integer value of a V4L2PixelFormat, both the
- * explicit value() and implicit uint32_t conversion operators may be used.
