## Detailed Description

Video stream for a camera.

The Stream class models all static information which are associated with a single video stream. Streams are exposed by the Camera object they belong to.

Cameras may supply more than one stream from the same video source. In such cases an application can inspect all available streams and select the ones that best fit its use case.

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.
