It is a Video for Windows Video and Audio capture driver that is plug and play compatible. This driver works only with Bt848/Bt878/Ct878A cards sold by the Osprey Technologies Division of ViewCast.com. Testing the Driver: ========================================================== ========================================================== Click on "VidCap32" in the Osprey MultiMedia Capture program group to test the driver. Manuals and Help: ========================================================== ========================================================== 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. Upgrading from Windows NT 4.0 to Windows 2000: ========================================================== ========================================================== If the Osprey card(s) are now installed on a PC that was running Windows NT 4.0 and was upgraded to windows 2000, you will have to install this software. *The Windows NT 4.0 Osprey drivers are not compatible with Windows 2000.* Following any of the two options in section (2) "Osprey Card(s) is Physically Installed & Previous Driver Installation" under the heading "Osprey-100/101/200 Windows 2000 Installation" will be sufficient to bring your devices up to date. Osprey-100/101/200/210/220 Windows 2000 Installation: ========================================================== ========================================================== Depending on your system setup, you will have multiple options for the installation of the Osprey MultiMedia drivers. Following are the different scenarios and their methods of installation: * THREE INSTALL SCENARIOS There are three main situations that might apply to you: Scenario 1: Osprey Card(s) not Physically Installed in the PC. Scenario 2: Osprey Card(s) Physically Installed, but Osprey Software not Installed - RECOMMENDED METHOD. Scenario 3: Osprey Card(s) Physically Installed, and Previous Osprey Software Installed. If you have upgraded from Windows NT 4.0 or Windows 95/98 and had Osprey drivers installed on the previous operating system, follow Scenario 3. In all cases, the most efficient and complete installation method is to run the setup.exe program on the product CD or in the web package that you downloaded after you have installed the Osprey card(s). The setup program automates the Plug and Play steps required to install the drivers and ensures that they are performed correctly. It also installs the bundled applets and Users' Guide. If you have multiple Osprey capture cards in the system it sets all of them up at once. You can skip the detailed instructions if you are upgrading from one Osprey driver version to another. Just run the setup.exe file and all the updated components will be installed. -- SCENARIO 1:OSPREY CARD(S) NOT PHYSICALLY INSTALLED IN THE PC This is the method that we recommend if you are installing an Osprey card for the first time on a system, and the Osprey software has not yet been installed. This scenario is called the "Preinstall Scenario". After the install is run, as soon as an Osprey card is installed in the PC, it is detected and its drivers are started automatically. 1. Double-click the setup.exe file to start the installation. 2. Select Destination Folders and Program Folders when prompted. 3. You will then be prompted to preinstall the drivers. Select yes to continue. 4. A Message saying Digital Signature Not Found will now appear, asking Do you want to continue? Click Yes. 5. Choose No when prompted to reboot at this time. The Osprey software is now fully installed. It will be ready for use after you install the Osprey card in your computer. 6. When you are ready to install the card, shut down and install the Osprey card inside your computer. Then power up the computer and start Windows 2000. Windows 2000 will detect the newly present Osprey card, and begin to activate the pre-installed driver.It will prompt with a Digital Signature Not Found message twice for each card. This happens because Windows sees the audio and video sections of the card are two distinct logical devices. The logical audio device is present even on Osprey-100/101 cards that have extra video or power connectors in place of audio connectors. Click Yes in response to all of these messages, and click Yes to reboot when prompted by the System Settings Change window. The Osprey card will be ready for use after this reboot. -- SCENARIO 2: OSPREY CARD(S) PHYSICALLY INSTALLED, BUT OSPREY SOFTWARE NOT INSTALLED In this case you have two options: Option A: Run the Installation Program (Recommended): When windows 2000 is first started for the first time after the Osprey card is installed, the New Hardware Found wizard will appear one or more times. CANCEL OUT OF THESE WIZARDS. After Windows 2000 has finished starting, do the following: 1. Double-click the setup.exe file. This will start the installation program. 2. Select Destination Folders and Program Folders when prompted. 3. One or more Digital Signature Not Found windows may appear during the installation process. Click Yes in each of them continue. 4. When the installation is finished, there is no need to restart the PC. Your Osprey card(s) can be used directly. If there are multiple Osprey cards in the system, this installation method will set up all of them at once automatically. Option B: Use the New Hardware Found Wizard (Not Recommended): This method is more complicated than Option A. It is particularly inconvenient if you are installing multiple cards at once, since each card has to be set up separately. When Windows 2000 starts it detects the new card(s) and starts the New Hardware Found wizard. Note: For all Bt/Ct878-based Osprey cards, the Wizard detects two logical devices for each card- a Multimedia Video Controller device and a Multimedia Controller device. The Multimedia Video Controller is the video section of the Bt/Ct878 device; the Multimedia Controller is the audio section. The audio logical device is present even on Osprey-100 and Osprey-101 cards that have video or power connectors in place of the audio inputs. When the Hardware Wizard detects a device: 1. Note carefully whether the Wizard says Multimedia Video Controller or Multimedia Controller (audio device). Click Next. 2. Choose Search for a suitable driver... option and click Next. 3. Check the Specify a Location box and click Next. 4. Use the Browse... button to locate the INF file o100drv.inf. This INF file is located in the same directory as the driver files that you are installing either on the CD or in the temporary directory where you expanded the web package. Then click OK. 5. Click Next. Highlight the description of the Osprey device you are installing. Click Next. 6. A Digital Signature Not Found windows will appear. Click Yes to continue. 7. Click Finish, then click Close to exit the Hardware Wizard. 8. If you are installing multiple Osprey cards, this sequence will appear once for each card. 9. If you wish to use the Osprey application software, or access the online Users' Guide from the Start Menu, you will still have to run the installation program after Windows 2000 has finished starting. Double click on the Osprey setup.exe file to run the install. -- SCENARIO 3: OSPREY CARD(S) PHYSICALLY INSTALLED, AND PREVIOUS OSPREY SOFTWARE INSTALLED This scenario is for the case when the Osprey card is physically installed in the PC and there is a previous installation of the Osprey drivers. These methods work for upgrades either from an old Osprey Windows 2000 driver to a newer one, or - if you have upgraded the operating system -from a Windows NT 4.0 driver to a Windows 2000 driver. Under this scenario you have two options. With both options, it is not necessary to uninstall the old driver before installing the new driver. Option A: Run the Installation Program (Recommended) 1. Double click the setup.exe file. This will start the installation program. 2. Select Destination Folders and Program Folders when prompted. 3. Messages saying Digital Signature Not Found will now appear, asking Do you want to continue? Click Yes for each message. This message will appear twice for each card, first for the Osprey Video Capture Device, then for the Osprey Audio Capture Device since they are two distinct logical devices. The logical audio device is present even on Osprey-100/101 cards that have extra video or power connectors in place of audio connectors. 4. If you have one or more Osprey-200s in the system, you will need to restart the system before you can use the updated audio. If you have video-only cards, you do not need to restart the system - the Osprey card(s) can be used immediately. Option B: Use the Device Manager (Normally not Recommended) This method will only install the drivers without updating the bundled applications, Users' Guide, or Start Menu. 1. From the Start Menu select: Settings -> Control Panel -> System ->Hardware -> Device Manager. 2. Double click the Sound, video and game controllers entry. 3. For each entry listed as Osprey Video Capture Device, Osprey Audio Capture Device, or similar description, perform the following steps: a. Double-click on the entry. A Properties dialog appears. b. Click on the Driver tab, then the Update Driver... button. c. The Upgrade Device Driver Wizard window will pop up. Click Next. d. Choose the Display a list of the known drivers for this device... option and click Next. e. Click the Have Disk... button which will bring up an Install From Disk window. f. Use the Browse... button to locate the new file o100drv.inf, located where the new driver files are located. Highlight this file, click Open in the browse box, then click OK. g. Click Next. Three Osprey device descriptions will be listed: Osprey Video Capture Device, Osprey Audio Capture Device, and Osprey Function 1 Placeholder. If the device you are updating is a video capture device, select Osprey Video Capture Device. If the device you are updating is an audio capture device: If your Osprey cards are Osprey-200s, select Osprey Audio Capture Device. If your Osprey cards are not Osprey-200s, select Osprey Function 1 Placeholder. If you have a mix of Osprey-200 and non-Osprey-100 devices, select Osprey Audio Capture Device. Click Next. h. An Update Driver Warning may appear at this point. If you have followed the instructions carefully, this is a safe operation. Click Yes. Click Next. h. A Digital Signature Not Found window will appear. Click Yes to continue. i. Click Finish to close the wizard. 4. When all devices are upgraded, click Close to exit from the device manager. 5. If you have one or more Osprey-200s in the system, you will need to restart the system before you can use the updated audio. If you have video-only cards, you do not need to restart the system - the Osprey card(s) can be used immediately. Multiple cards: ========================================================== ========================================================== It is important to note here that installing one instance of this software using the indicated "Recommended Methods" above, will setup multiple cards if they existed in the system. If the "Non-Recomended Methods" are used, then these methods will have to be repeated for each Osprey card in the system. 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 an optional utility 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 files 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. - Fixed problem where a user who is not a member of group Administrator could not view the Configuration tab of the Osprey driver's Control Dialog. 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.
