Analysis Task Output Tracks

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:

TIP:

Data and DataWithSource tracks contain a significant amount of information, often more than you want to output from Media Server. These tracks are most useful as the input for other tasks. For example, you can use the DataWithSource track from face detection as the input for face recognition, so that face recognition receives the location of each face in every frame and all of the source frames.

The following diagram shows how Media Server creates records (represented by blue rectangles) when a person appears in a video. All of the records in the following example would have the same ID because they all relate to the same detected face (the same event).

For information about the tracks that are produced by Media Server tasks, and the information contained in each track, refer to the Media Server Reference.
