Base class of all stream related images.
A stream related image is returned from a grab synchronization method like Stream.wait(). These kinds of images normally use an underlying ring buffer or a queue to reuse memory and increase performance. This then implies, that the validity of this image's data is limited according to the used acquisition engine / strategy.
By default, you expect images of this type to be valid from creation until the next synchronization / acquisition start.
The content of a stream image may be overwritten, depending on cvb.RingBufferLockMode.

float: Gets the raw timestamp as reported by the driver.
This value's unit depends on the driver used.
