The PDAC download file includes the data files and dictionary files (DDFs) for PVideoDB, but you must create the database itself. The data files and DDFs are located in samples PvideoDB, where is the directory where you installed the PDAC header files and samples. Use the following steps to create the PVideoDB database, which is required to use the PDAC samples. When everything else falls flat check out the driver installation application.
