WolfVision Video Capture II (version 2.7) DirectShow Video Capture driver for WolfVision Visualizers and cameras (afterwards called "Visualizers") General Information =================== This video capture driver can be used to capture a video stream from a WolfVision Visualizer with a suitable video capture application (e.g. VirtualDub, Adobe Premiere, etc.). With this driver you can also use a WolfVision Visualizer the same way like a web cam (e.g. Skype, MS NetMeeting or other applications capable of grabbing video signals from connected cameras). Things to consider ================== 1) The driver is designed to work with 32 and 64 bit versions of Windows 7, Windows 8, Windows 8.1 and Windows 10. 2) It is not allowed to change the picture aspect ratio of the Visualizer while video capture is running, e.g. no switch from 4:3 to 16:9 output resolution or changing into Image turn mode (90 or 270 degrees rotation angle). 3) The list of available Visualizers is only generated once when the driver is loaded by a capture application. The Video Capture driver will not detect when a already discovered Visualizer is disconnected or a new unit will be connected during the driver is running. The application will show a black image when you accidentally select a Visualizer which is no longer present. 4) If you have a previous version of the WolfVision Video Capture driver (e.g. WolfVision Video Capture x.x) installed, please uninstall it before using the new version. Otherwise you won't be able to get a picture from the Video Capture II driver. Known issues ============ 1) The combination of Windows 8/8.1 and Skype is not working with this driver. Skype will crash immediately after startup when Video Capture II driver is installed. You can only prevent this from happening if you disable the driver in the Device Manager of Windows before you startup Skype. This is a commonly observed bug with Skype on Windows 8/8.1. On Windows 7/10, Skype is working fine with this driver. Troubleshooting =============== 1) The application will show a black image when: * Selected Visualizer is switched off Solution: Turn the desired Visualizer on * Selected Visualizer is in an in-compatible mode, e.g. Digital Zoom mode Solution: De-activate the in-compatible mode (or switch the desired Visualizer off and on again to perform the power-on preset) * Selected Visualizer is disconnected Solution: Re-connect the desired Visualizer on the USB-port and restart your capture application * Communication error occurred with the selected Visualizer Solution: Disconnect and re-connect the desired Visualizer on the USB-port and restart your capture application 2) The application will show a corrupted image. One or more of the following reasons might apply: * Aspect ratio of picture was changed while video capture was running Solution: Undo the change or restart your capture application * The selected Visualizer was changed while video capture was running Solution: Undo the change or restart your capture application * The selected device is in the View mode (Show All) Solution: Disable the View mode (Show all) 3) Your Visualizer isn't listed on the drivers property page for selection. This might be caused by a previously occurred error in the USB communication with the respective Visualizer. Solution: Disconnect and re-connect the desired Visualizer on the USB-port and restart your capture application 4) Only applies to 64 bit operating systems: You can use the video capture driver for getting a video stream from a Visualizer but you can't open the drivers property page. This is because the version of your capture application doesn't match with the driver/OS version. It's not possible to open the property page of a 64 bit driver on a 64 bit operating system if the used capture application is a 32 bit version. Solution: Try to get a 64 bit version of your capture application and use this version for capturing For further assistance and troubleshooting, please contact the WolfVision support team at support@wolfvision.com
