=============================================== Osprey Video Division ViewCast Corporation Osprey-500 Capture Driver For Windows XP Version 2.1 Build 423 11/2001 Release Notes =============== This version of the driver is for Windows 2000 and XP only. It is a Video for Windows Video and Audio capture driver that is plug and play compatible. This driver works only with cards sold by the Osprey Technologies Division of ViewCast.com. This release is a Windows XP pre-release awaiting documentation updates. Refer to the Osprey-500 User's Guide, for detailed information about the board and driver. You can access the User's Guide, which is in HTML format, by opening the UsersGuide.htm file located at the root install directory. The User's Guide can also be accessed from the Osprey-500's program group menu after the installation. IE 4.0 or later or Netscape 4.5 or later are required for viewing the user guide. Revision History ================ Changes from 1.0.6 Build 2.2 to 1.0.6 Build 2.3: ================================================ - 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. - Fixed install program so that VFmtDlgCfg is set correctly in registry. - Updated user manual. - A defect exists in the uninstall program. Uninstalling the driver does not remove driver files from the system32 and system32\drivers directories. See Appendix G in user manual for a list of files to remove manually. Changes from 1.0.5 Patch 1 to 1.0.6: ==================================== - Removed the Microsoft Application exclusivity requirement from the audio and video drivers. The Osprey-500 can now work and be fully utilized with any VFW or DirectShow based audio/video application. Changes from 1.0.5 to 1.0.5 Patch 1: ==================================== - Fixed "no audio present" bug that occurred when multiple Osprey cards were installed in some types of machines. - Fixed audio source selection bug caused by installing both Osprey-100 and Osprey-2x0 devices in same machine with the Osprey-500. - Fixed audio echo that would occasionally occur during long encoding sessions. - Fixed audio initialization bug on Osprey-500s that would require a hardware reboot. The bug symptom was that analog audio capture would produce silent data. - Prevents blue screen when a kernel driver synchronization fault is detected. Changes from 1.0.4 to 1.0.5: ============================ - Fixed bug that caused Osprey-500 DV and Osprey-500 Pro cards to display incorrect audio ports. - The WMCap utility is not part of the Osprey-500 software. It is distributed by Microsoft. WMCap is part of Microsoft's Windows Media 7 Resource Kit. You can download it from http://www.microsoft.com/windows/windowsmedia/en/technologies/resource.asp - The Osprey driver includes a new Bypass Color Correction checkbox on the Video Source page of the driver control dialogs. This checkbox applies ONLY to digital video sources. Check Bypass color correction to turn off all saturation, contrast, and brightness conversion in hardware and pass digital video data directly to the host. This is most useful for the SDI and DV input sources. - The Audio Settings applet has been removed from the release. See Appendix I for instructions about setting software gain and rate conversion method parameters. Changes from 1.0.3 to 1.0.4: ============================ - 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-500 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. Changes from 1.0.2 to 1.0.3: =========================== - new WMCap utility has been added. WMCap is a DirectShow application that will capture AVI files. WMCap is an approved application which can utilize the full features of the Osprey-500 card, such as digital video and audio capture. WMCap requires DirectX 7, which is installed as part of Windows XP. WMCap will run only on Windows XP. - The otiyuv.dll has been fixed for the problem that indirectly caused the Windows Media Encoder 7 error/failure: "An unexpected error has occurred with the audio codec. 0xc00d0bc3" - Fixed bug in otiyuv.dll for YUV->RGB32/24 color conversion. Previously two of the component values were swapped yielding a color shift in the resultant decoded image. - Added otiyuv.dll as the decoder for the 422packed (YUY2) color format. This creates a drivers32 registry setting of vidc.yuy2 == otiyuv.dll - Title bar of driver control dialogs correctly identify Osprey cards when configuring Osprey-500 DV and Osprey-500 PRO cards. - Driver supports situation in which digital audio source (AES/EBU or S/P-DIF) is selected but source is not connected to card, or is not providing data. In this situation, the Osprey-500 will internally generate a 48kHz audio stream containing silence. When data is available from the source, the Osprey-500 will automatically switch from the internally- generated 48kHz stream to the input 48kHz source. Changes from 1.0.1 to 1.0.2: =========================== - Added support for PAL - Made aware of w2000 \MediaResources\msvideo entries. Able to set a VfW driver as "default" even when WDM driver(s) are listed in \MediaResources\msvideo. - Grayed out unavailable inputs in Video Source tab and audio mixer for Osprey-500/DV and Osprey-500/PRO boards. - Made special characters in closed-captioning work. Improved closed-captioning decoding. - Removed green flash at start of encoding when filter is enabled. - Grayed out digital video sources when Osprey-100 Analog Mode is enabled. - Fixed bug that caused Osprey-500/DV and Osprey-500/PRO to not have Osprey-500 tab in Video for Windows configuration dialog box. - Fixed coexistence problem with Osprey-200 or other Conexant 878 based cards. Please note that the Osprey-200 also requires a driver update. - Improved audio sample rate detection for digital audio sources - The Audio Settings applet places registry values in this twig of the registry: HKEY_LOCAL_MACHINE\SOFTWARE\Osprey\Osprey500\DeviceX\Audio\RateConversion HKEY_LOCAL_MACHINE\SOFTWARE\Osprey\Osprey500\DeviceX\Audio\Gain RateConversion chooses the method that the Osprey-500 uses to convert audio from one sampling rate to another. For instance, your DV camcorder may provide only 48kHz, but you use a RateConversion method to convert the data rate to 32kHz. For most purposes the default setting of Filter Converter works well. When RateConversion is: 1 - use filter converter (default) 2 - use skip converter (skips samples) 3 - use Microsoft PCM method The default value of Gain is 2. Set it higher for increased software audio gain, and set it below 2 to decrease gain. - Use dB scale for audio peak detection - Fixed reporting of audio peak values - Fixed volume setting on digital inputs Latest Drivers ================= Before installing, check the Osprey Video website or the ftp site for the latest drivers: For the Osprey Video support website, navigate: www.ospreyvideo.com --> Osprey 500 --> Get Software --> click on the Download link for your operating system For the ftp site, go to ftp://ftp.viewcast.com/pub/OSP-500/winxp/latest/ If there isn't a newer driver at the time of your installation, please check the website or ftpsite frequently thereafter. Osprey-500 Windows XP Installation: ======================================= Depending on your system setup, you will have multiple options for the installation of the Osprey-500 drivers. Following are the different scenarios and their methods of installation: * TWO INSTALL SCENARIOS There are two 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 Option A: Run the Installation Program (Recommended) Option B: Use the Found New Hardware Wizard (Not Recommended) 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. 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. If you are upgrading from one Osprey driver version to another, you must first uninstall the current version before installing the new one. -- 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. Messages saying "The software you are installing for this hardware has not passed Windows Logo testing to verify its compatibility with Windows XP" will appear. It was also say that "Continuing your installation ofthis software may impair or destabilize the correct operation of your system either immediately or in the future..." Click "Continue Anyway" 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. This happens because Windows sees the audio and video sections of the card as two distinct logical devices. The logical audio device is present even on Osprey-500 cards that have extra video or power connectors in place of audio connectors. 5. The Osprey software is now fully installed. Assuming you want to use the Osprey card and drivers immediately, shut down Windows XP, install the card, and restart your computer now. When it starts, Windows XP will automatically recognize the card and start its preinstalled drivers. You do not have to install the Osprey card or restart the system immediately. At any time in the future, if Windows 2000, when starting, finds an Osprey card(s) installed, it will automatically activate the driver. -- SCENARIO 2: OSPREY CARD(S) PHYSICALLY INSTALLED In this case you have two options: Option A: Run the Installation Program (Recommended): When Windows XP is first started after the Osprey card is installed, the Found New Hardware Wizard will appear one or more times. Cancel out of these wizards. After Windows XP 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 messages saying "The software you are installing for this hardware has not passed Windows Logo testing to verify its compatibility with Windows XP" may appear. It was also say that "Continuing your installation ofthis software may impair or destabilize the correct operation of your system either immediately or in the future..." Click "Continue Anyway" 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. This happens because Windows sees the audio and video sections of the card as two distinct logical devices. The logical audio device is present even on Osprey-500 cards that have extra video or power connectors in place of audio connectors. 4. When the installation is finished, you must restart your PC. 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 Found New Hardware 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 XP starts it detects the new card(s) and starts the Found New Hardware Wizard. Note: For all 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 device; the Multimedia Controller is the audio section. 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 o500drv.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. Messages saying "The software you are installing for this hardware has not passed Windows Logo testing to verify its compatibility with Windows XP" will appear. It was also say that "Continuing your installation ofthis software may impair or destabilize the correct operation of your system either immediately or in the future..." Click "Continue Anyway" 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. This happens because Windows sees the audio and video sections of the card as two distinct logical devices. The logical audio device is present even on Osprey-500 cards that have extra video or power connectors in place of audio connectors. 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 XP has finished starting. Double click on the Osprey setup.exe file to run the install. Important Notice ================ If you are using an Osprey-100 or Osprey-200 card in the same machine as your Osprey-500 card, we strongly recommend that you upgrade the 100/200-family card to the version 1.55 or later driver.
