Patch 1/6 starts by moving the V4L2PixelFormat class to a separate file, without modifying the code. Patch 2/6 then moves format conversion from V4L2VideoDevice to V4L2PixelFormat, and patch 3/6 replaces the big switch-case's with std::map. Patch 4/6 further rework V4L2PixelFormat by splitting the PixelFormatInfo class out and exposing it as an internal API. Patch 5/6 adds Bayer formats support to both PixelFormatInfo and V4L2PixelFormat. Path 6/6 finally adds additional data to PixelFormatInfo.
