The events that occur in video usually span multiple frames. For example, a person, object, or logo might appear on screen and remain there for seconds or minutes. Media Server analysis tasks run analysis on single frames, but also follow events across multiple frames.
Analysis tasks can produce the following tracks:
The following diagram shows how Media Server creates records (represented by blue squares) when a person appears in a video.
Event
track when the person appears and disappears from the scene.Data
and DataWithSource
tracks for each analyzed frame. If there are multiple people in the scene, Media Server creates multiple records in the Data
and DataWithSource
tracks for each frame.Result
and ResultWithSource
tracks for each event (in this case a detected face). This record spans the event and summarizes the analysis results.
For information about the tracks that are produced by Media Server tasks, and the data contained in each track, refer to the Media Server Reference.
