6.2 Enable Camera Streaming with Initial VPAC Configuration

After verifying that the camera and its driver work functionally and the GStreamer plugins for VPAC supports the new sensor, this step is to run live streaming with an initial VPAC configuration. The purpose of this step is to make sure that the GStreamer plugins for VPAC work properly. The live streaming will also make next steps easier, for example, for adjusting camera mounting position.

The initial DCC binaries are automatically generated by Python scripts so that both VPAC and Auto Exposure (AE) program are set up properly for the sensor resolution and color format. TI's reference imaging software provides necessary tools to generate an initial VPAC configuration (or DCC profile), as described in sections below.
