It is a Video for Windows Video and Audio capture driver. This driver works only with Bt848/Bt878/Ct878A cards sold by the Osprey Technologies Division of ViewCast.com. Click on "VidCap32" in the Osprey MultiMedia Capture program group to test the driver. The document SimulStreaming_Users_Guide.pdf contains general information about the SimulStreaming capabilities which are available at added cost in this driver version. There are 2 User's Guides included with this release. For detailed information about the Osprey-210 and 220 boards and driver, refer to the Osprey-210/220 MultiMedia Capture Device User's Guide. Refer to the Osprey MultiMedia Capture Driver - User's Guide, for detailed information about the Osprey-100, 101, and 200 boards and driver. These 2 manuals are in PDF format, and are kept in folder \WinNT on the CD. After the driver has been installed, shortcuts to these Users's Guides are placed in the "Osprey MultiMedia Capture" program group, as "Osprey 210-220 Manual" and "Osprey 100-200 Manual". These manuals require the Adobe Acrobat Reader, which is available on the CD, or by download from www.adobe.com. You can read the manuals on the CD by opening files Osprey210-220_Manual.pdf and Osprey100-200_Manual.pdf. The Help inside the Osprey driver is in HTML. This Help requires a frames-capable browser with JavaScript enabled, such as Microsoft IE 4.0 or later, or Netscape 4.5 or later. Installation: ========================================================== ========================================================== During the course of this installation, you will be prompted to select from amongst three setup types: "Osprey-100", "Osprey-200/210/220" or "Custom". Select the: 1. "Osprey-100" setup type, if you are installing any combinations of Osprey-100 cards and/or Osprey-101 cards, only. If one of the cards you are installing is an Osprey-200, select one of the other setup types. 2. "Osprey-200/210/220" setup type, if you are installing any combinations of Osprey-100 cards, Osprey-101 cards, Osprey-210, Osprey-220, and/or Osprey-200 cards. 3. "Custom" setup type if you want more control over the installation. You will be prompted to select which components that you want to install. Changes from version 2.0.0 build 135 to build 252: ======================================================== - A bug which caused audio failure on some machines where Device Properties address of PCI device was 0, has been fixed. Changes from version 1.55 to 2.0.0: ======================================================== - Versions 2.0.0 and later are capable of SimulStreaming. - A new feature has been added to the Video Source Page of the control dialog. This control is a checkbox entitled "Force odd-even frame order". It does not give the user full control over the scan order. Specifically, the user cannot force even-odd field order. If the box is checked, field order is forced to odd-even. If the box is unchecked, the driver chooses the field order that will give fastest performance. - The parameter 'Access to Multiple Boards' on the Video Configuration page has been changed to 'Multiple Opens'. The meaning of this checkbox has also been changed. This checkbox should be selected when using the SimulStreaming feature of the driver. - When SimulStreaming, only 1 session can enable the Closed Caption 'Save to File' option. - Fixed a bug in mixer driver that caused CPU utilization to hit 100% if card was installed in the same machine as a SoundBlaster Live! soundcard and optional software from Creative. Changes from version 1.54: ============================================= - The software gain setting in the registry has been moved to HKEY_CURRENT_USER\SOFTWARE\Osprey\Osprey200\DeviceX\Audio\Gain This applies only to Osprey-200 cards, and not to Osprey-210 and 220 cards. - Non-administrator users can now set and save all audio controls (audio source and volume settings). These settings are now stored in a registry location which does not require Administrator rights to change. - The Audio Settings applet has been removed. - A bug which caused portions of the Osprey-100 VFW SDK MMAC_o100_SRC_CONTROL interface to not work correctly has been fixed. - A bug which caused balanced audio to be unavailable on Osprey-220 cards has been fixed. - The msvideo string written to the registry has been shortened. Some machines limit this string to 31 characters. - Extraneous file oemsetup.inf has been removed. Changes from version 1.53: ============================================= - The Osprey driver includes the new capability to crop the incoming video signal in hardware before it is encoded or captured. Please see the CropApp Manual (in PDF format) which is installed in the Osprey MultiMedia Capture program group for details on using this feature. It is HIGHLY recommended that users read this entire document before enabling hardware cropping. - A method for improving video quality under conditions of PCI bus contention has been added. Known issues in version 2.0.0: ========================================================== ========================================================== - RealProducer / Heavy Load Problem: There is a known problem with RealProducer in which it adds video buffers to the capture device before RealProducer has finished processing the buffers. Typically under non-loaded CPU utilizations this is not a problem because the buffer can be processed by RealProducer before being prepared for capture. However, under heavy CPU load, the capture driver can prepare the buffer for capture before RealProducer finishes or even starts processing the buffer. The result is typically a processed image that has a multicolored pattern in the image. The size / height of this pattern depends on how far RealProducer has processed the buffer before it is prepared for capture. If you find this situation occurs first try to reduce your CPU load before contacting Osprey support. DXMedia: ========================================================== DXMedia version 6.0 works with DirectX version 3.0 for Windows NT. The DXMedia package must be installed in order for Microsoft Windows Media Encoder versions 7.0 and later, and AmCap, to function properly. It is provided on the CD. See the Installation chapter of the Users' Guide for instructions on where to download it.
