+ * @pipe:		the media pipeline object associated with this stream

+ * @pipe_size:		size of @ved_pipeline
+ * @kthread:		thread that generates the frames of the stream.

+ * When the user call stream_on in a video device, struct vimc_stream is
+ * used to keep track of all entities and subdevices that generates and
