+ * \brief Video stream for a Camera
+ *
+ * A camera device can provide frames in different resolutions and formats
+ * concurrently from a single image source. The Stream class represents
+ * one of the multiple concurrent streams.
+ *
+ * All streams exposed by a camera device share the same image source and are
+ * thus not fully independent. Parameters related to the image source, such as
+ * the exposure time or flash control, are common to all streams. Other
+ * parameters, such as format or resolution, may be specified per-stream,
+ * depending on the capabilities of the camera device.
+ *
+ * Camera devices expose at least one stream, and may expose additional streams
+ * based on the device capabilities. This can be used, for instance, to
+ * implement concurrent viewfinder and video capture, or concurrent viewfinder,
+ * video capture and still image capture.

+ *
+ * Some cameras are capable of supplying more then one stream from the same

+ *
+ * \todo Add capabilities to the stream API. Without this the Stream class only
+ * serves to reveal how many streams of unknown capabilities a camera supports.
+ * This in itself is productive as it allows applications to configure and
+ * capture from one or more streams even if they won't be able to select the
+ * optimal stream for the task.
