The following diagram shows a simple configuration for performing OCR on a video stream and sending the results to IDOL Server. The setup includes an ingest engine, an analysis engine, and an output engine. These are usually the minimum required for any configuration.
Process
action, which starts a new session. The Libav ingest engine receives video from the source specified in the action. The Libav engine produces an image track and audio track.A HPE Media Server configuration that matches this process is shown below.
OCRtext
task includes the parameter Input=Image_1
, which specifies that the input for the OCR task is the Image_1
track from the ingest engine. Setting the Input
parameter is optional, because by default HPE Media Server processes the first available track of the correct type.IDOLOutput
task includes the parameter Input=OCRtext.Result
. This specifies that the input for the IDOL output task is the Result
track from the OCRtext
task.[Ingest] IngestEngine=LibAvIngest [LibAvIngest] Type=libav [Analysis] AnalysisEngine0=OCRtext [OCRtext] Type=ocr Input=Image_1 [Output] OutputEngine0=IDOLOutput [IDOLOutput] Input=OCRtext.Result Type=idol Mode=time OutputInterval=60s XslTemplate=./xsl/toIDX.xsl
