The purpose of this (thin) layer is to make it +easy for application writers to support a wide variety of devices without +having to write separate code for different devices in the same class. libv4l +consists of 3 different libraries: libv4lconvert, libv4l1 and libv4l2. + +libv4lconvert offers functions to convert from any (known) pixel-format +to V4l2_PIX_FMT_BGR24 or V4l2_PIX_FMT_YUV420. + +libv4l1 offers the (deprecated) v4l1 API on top of v4l2 devices, independent +of the drivers for those devices supporting v4l1 compatibility (which many +v4l2 drivers do not). + +libv4l2 offers the v4l2 API on top of v4l2 devices, while adding for the +application transparent libv4lconvert conversion where necessary. + +WWW: http://hansdegoede.livejournal.com/3636.html |
