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.
Processaction, 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 Media Server configuration that matches this process is shown below.
OCRtexttask includes the parameter
Input=Default_Image, which specifies that the input for the OCR task is the first image track from the ingest engine. Setting this parameter is optional, because the default value of the
Inputparameter for engines that require images is
IDOLOutputtask includes the parameter
Input=OCRtext.Result. This specifies that the input for the IDOL output task is the
Resulttrack from the
