Revision History ========================================================== ========================================================== Changes from 2.2.1 Build 11 to 2.2.2 Build 18: ========================================================== - Added support for new Osprey-560 card. - Fixed blue screen crash that occurred on some systems (including some Dell PowerEdge servers) during installation of audio driver. - Provided registry-enabled workaround for data loss/repeated video lines which occurs with some motherboard bridges and chipsets. To enable, set HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\o540drv\Config to 0x00100002 and reboot. - Provided registry-enabled workaround to turn off SimulStream warning message that displays when SimulStream is not enabled or starting an encoding session with a larger image size than a currently running stream. To enable workaround, set HKEY_CURRENT_USER\Software\Osprey\Osprey540\Device0\VcDll\ExtFlags to 0x100. For more than one device, replace Device0 with the appropriate device number. - Fixed problem where video driver crashed or behaved incorrectly when application requested HD video size (larger than 720x480 for NTSC). - Added support for SDI audio channels 3 and 4. Changes from 2.2.0 Build 358 to 2.2.1 Build 11: ========================================================== - Fixed Blue Screen crash which could possibly happen when installing multiple Osprey cards. - Fixed error in pre-install Installation scenario. Changes from 2.1.5 Build 78 to 2.2.0 Build 358: ========================================================== - A new feature available in this release of the Osprey-540 driver is a free 10-day test drive of the Osprey SimulStream(TM) feature. Included in this release is a 10-day evaluation license for SimulStream. There is a user option to toggle this capability on and off. While in evaluation mode a watermark will appear on the active video region which denotes usage of an evaluation version of Osprey SimulStream (TM). After the 10-day trial period has expired, one may renew the Osprey SimulStream (TM) evaluation by visiting our website at http://www.ospreyoffers.com/ospreysseval. - Added warning message to warn that no SimulStream license is present if user tries to open 1 board in multiple capture/encoding sessions without SimulStream feature enabled. - Fixed bug which could possibly crop incorrect vertical region if the user had enabled SimulStream capability but not CC decoding. - Changed timeout-period in driver startup for checking whether a SimulStream evaluation key is enabled. - Applet o500audstat has been removed from the release, but is available from Customer Support. - The Closed Caption checkbox is now disabled when the Video Standard in use is PAL format, or when DV is selected for video source; the PAL video standard and DV sources do not support CC. - Audio upsampling quality has been improved. - Fixed potential audio capture failure to start problem. - When matching audio and video devices, changed to use only the lower 4 bits of PCI bus. This fixes problem for Magma expansion chassis. - Fixed a bug which could result in a race condition when using SimulStream feature. Fixed bug which could consume 100% of CPU when driver control dialog was open. - Fixed memory access violation in driver. - Fixed a bug in resuming from power-down state. - Fixed problem of analog video input being too dark (AGC). - Corrected Saturation and Contrast settings for Video-out. - Fixed a bug which produced 'pop' sound on audio-out port when selecting SDI or AES audio. - A bug which caused audio failure on some machines where Device Properties address of PCI device was 0, has been fixed. Version 2.1.5 Build 78: ================================================ - Initial driver release for Osprey-540 - The level meter in the audio Record Control mixer works at all times, whether the user is capturing or not. If audio signal is present, the level meter 'lights up'. Known issues in version 2.2.2: ========================================================== ========================================================== - The video-out signal from the Osprey-540/560 card is only valid when a video input signal is present. - With the existing SimulStream architecture, you MUST pair your fastest desired framerate with your session with the largest pixel size resolution when creating multiple capturing/ encoding sessions using the optional SimulStream feature. This is explained in the SimulStreaming_Users_Guide.pdf as "...all frames must be scaled copy or none of the frames must be scaled copy." If you do not follow this guideline, some streams may fail to start encoding/capturing, or a blue screen crash could possibly occur. The driver will display a warning message if the Nth stream which you attempt to start violates this guideline. - RealSystem Producer 8.5 / Heavy Load Problem: There is a known problem with RealSystem Producer 8.5/8.51 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. Osprey-540/560 Windows 2000 Installation: ========================================================== ========================================================== Depending on your system setup, you will have multiple options for the installation of the Osprey-540/560 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 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. 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-540/560 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 2000, install the card, and restart your computer now. When it starts, Windows 2000 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 2000 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 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, 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 2000 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 o540drv.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. Important Notice ========================================================== ========================================================== If you are using an Osprey-100, Osprey-200/210/220, Osprey-500, or Osprey-2000 card in the same machine as your Osprey-540/560 card, we strongly recommend that you use version 2.0.0 or later drivers on all Osprey cards.
