1.15.2 Logging
The DirectShow_acquire logging procedure is equal to the logging of the MATRIX VISION products which uses
mvIMPACT Acquire. The log output itself is based on XML.
If you want more information about the logging please have a look at the Logging chapter of the respective "mv←-
IMPACT Acquire API" manual or read on how to configure the log-output using mvDeviceConfigure in the "mv←-
IMPACT Acquire GUI Applications" manual.
1.15.3 Setting up devices for DirectShow usage
In order to be able to access a device through the mvIMPACT Acquire driver stack from an application through
DirectShow a registration procedure is needed. This can either be done using mvDeviceConfigure or by a command
line tool that is part of the Windows operating system.
