Syntax

chunkinfo = chunkDataInfo(src)

Description

chunkinfo = chunkDataInfo(src) returns a listing of available and enabled fields for video chunk data for the videosource object, src. To enable chunk data reading from the hardware, set src.ChunkModeActive = "True". You use src.ChunkSelector and src.ChunkEnable to configure individual fields of chunk data.

Note

This function supports only GenICam™ GenTL compliant hardware.
