Setting Up A Device For DirectShow

For using devices, DirectShow needs a public adapter that must be registered with the operating system. As described in Registering Devices , this can be done with the help of DeviceConfigure .

Note: If running a 64-bit DirectShow application, make sure to use a 64-bit version of DirectShow_Acquire, which can only be installed with a 64-bit version of DeviceConfigure . (And respectively for a 32-bit version)

Connect the device to the host.
Power the camera using a power supply at the power connector.
Wait until the status LED turns blue.
Open the tool DeviceConfigure ,
set a friendly name ,
and register the device for DirectShow .

Note: In some cases it could be necessary to repeat step 5.

Changing Camera Properties

When selecting a DirectShow_Acquire camera as a DirectShow capture device (in the "Open Capture Device" dialog), there are two possibilities to display the camera property dialog:

A. Click the checkbox "Show more options" and append " :dshow-config" to the options in the bottom edit box:

B. Alternatively, press the button "Advanced options" and, in the window that is going to be displayed, click the checkbox "Device properties" followed by pressing "OK". This fills in all the relevant settings of the dialog into the edit box in the "Open Media : Capture Device" dialog from solution A above.

After selecting the activity to invoke (Play/Stream/Enqueue/Convert), the DirectShow_Acquire property dialog will open.

Note: Most properties in this dialog control the camera directly, so they stay the same as long as the camera is not reset. Properties that control streaming (like the ImageDestination::PixelFormat) are set by the VLC Media Player each time the capture device is started.

After pressing "OK", the selected activity will start.
