GPUNumParallel The maximum number of video frames to analyze concurrently using the GPU (per CPU thread).
Input The track that you want to process.
NumParallel The maximum number of CPU threads to use for analysis.
SegmentDuration The maximum duration of a record in the SegmentedResult or SegmentedResultWithSource track.
Type The analysis engine to use. Set this parameter to Demographics.

Output Tracks

Output track Description Output1
Data Contains one record, describing the analysis results, for each input record. No
DataWithSource

The same as the Data track, but each record also includes the source frame.

No
Result Contains one record, describing the analysis results, for each detected face. Yes
ResultWithSource

The same as the Result track, but each record also includes the best source frame.

No
SegmentedResult

(Available only when processing video). The same as the Result track, except the duration of each record is limited by the parameter SegmentDuration. If a result exceeds the specified duration, Media Server begins a new record with the same ID.

Yes
SegmentedResultWithSource

(Available only when processing video). The same as the ResultWithSource track, except the duration of each record is limited by the parameter SegmentDuration. If a result exceeds the specified duration, Media Server begins a new record with the same ID.

No

NOTE: To use the SegmentedResult or SegmentedResultWithSource tracks, ensure that the input for the face demographics task is the DataWithSource track produced by face detection.
