This message has oneof_ fields (mutually exclusive fields).
For each oneof, at most one member field can be set at the same time.
Setting any member of the oneof automatically clears all other
members.
int
Streaming mode ONLY. In streaming mode, we do not know the
end time of a tracked object before it is completed. Hence,
there is no VideoSegment info returned. Instead, we provide
a unique identifiable integer track_id so that the customers
can correlate the results of the ongoing
ObjectTrackAnnotation of the same track_id over time.
This field is a member of oneof_ track_info.
