This version of the driver is for Windows XP only.  Windows
2000 is not supported for this driver, but may be installed
with certain limitations as described in the section
"Limitations on Windows 2000".  DirectX 9 is required.

This driver works only with cards sold by the Osprey
Video Division of ViewCast Corporation.

Installation over a previous Osprey WHQL-signed driver
This driver has not been signed by WHQL.  When installing
on a machine with a previous Osprey driver signed by WHQL,
it is highly recommended that you remove the old driver
and reboot before installing this driver.  Go to the
Control Panel Add/Remove Programs to remove old driver
files.  After rebooting the machine, cancel out of the
Install Wizard and follow the instructions for Windows XP
Installation at the end of this file.

It is also highly recommended that all Osprey cards to be
used with the driver are installed in the system before
installing the driver.  If another Osprey card is added
to the system after installing the driver, Windows will
by default prefer to install the previously signed driver
for the new device.

If the installation program for this driver appears to
hang, press Alt-Tab to ensure that the installation screen
is not hidden.

Testing the Driver
Run "VidControl" or "SwiftCap" under
Program Files\\Osprey 540 and 560\Samples to test
the driver.

Revision History
Changes from 3.1.0 to 3.1.2
- Corrected installation conflict issue noted to occur
with Adobe Acrobat version 7.0
- Corrected issue related to PAL loopback source displaying
black bar on source content
-  Corrected audio source configuration settings such that
audio settings that are selected in the driver are main-
- Corrected audio preview feature
- Enabled the pre-installation of drivers

Changes from 3.1.0 RC1 to 3.1.0 RC2

- Problem in RC1 in which the video would stop after an 
  interval of 10 to 40 minutes on machine-specific 
  machines is corrected.

Known Issues in RC2
When two SimulStreams are running the exact same format,
starting or stopping one stream may cause the other stream
to stop as well.

This driver is fully functional under Windows XP only.
See below for limitations with Windows 2000.

This driver does not support Windows Media Encoder 7.1.  
Please upgrade to Windows Media Encoder 9.

If both an Osprey-2x0 and an Osprey-540/560 are in the same
system, both types of devices should be updated to the 3.1.0
RC2 driver.  The driver property pages may not all work
correctly if this is not done.

The driver supports DV1394 audio capture at 32kHz (often
referred to as "12-bit").  There are clicks in 32kHz audio
from some DV sources but not others.  With some devices
but not all devices, the clicks disappear when the DV
device is repowered after setting the audio rate to 32kHz.
There does not seem to be any problems when the audio
sample rate is 48kHz ("16-bit").  Note that the driver
requires that the AudioConfig applet be used to force the
hardware capture rate to the same rate - 32 or 48kHz - as
the DV source.

If you install the Osprey MultiMedia Capture Driver version
3.0.0 on top of the Osprey-540/560 Capture Driver version
3.1.0, the installation may prompt you to overwrite the file.  The message may ask, "Overwrite the
English (United States) file with the unspecified language
one?"  If this message is displayed select "Yes".

Mixed Installation of VfW and AVStream drivers
To have a mixed installation that includes an Osprey Video for 
Windows (VfW) driver (driver version 2.2.2 or lower) for one
(or more) Osprey card(s) and the Osprey-540/560 3.1.0 
AVStream Capture driver for the other Osprey card(s) do the 

I.    Install the Video for Windows driver if it is not already

II.   Install the Osprey-540/560 3.1.0 Capture Driver.
      This will upgrade all devices to the AVStream drivers, 
      but will not delete the Video for Windows files from the
      PROGRAMFILES directory.

III.  Use the Device Manager and run the INF file to reinstall
      the VfW driver on one or more of the devices.

      1.  The following files must be present in the PROGRAMFILES
          directory (ex. C:\Program Files\Osprey 540 and 560\driver) 
          on your machine: o540drv.sys, o540vc.dll, o450a.sys,
          o540ausr.dll, o540_mix.dll, o540_wav.dll, o540board.dll,
          chewie.rbf, hutt_merge.rbf, and o100drv.inf.

      2.  On the Start Menu right click on "My Computer" and
          select "Properties" from the list.
      3.  When the next dialog box is displayed select "Hardware"
          from the top of the menu.

      4.  In the second row of the next dialog box there is a
          section called "Device Manager".  Click on the button
          to the right that says "Device Manager".

      5.  Double click on the heading that reads "Sound, video
          and game controllers".  There will be two or more 
          Osprey AVStream Devices in the drop down list.

      6.  Right click on the Osprey device that you want to set 
          up with the VfW driver, and select "Update Driver...".

      7.  When the Hardware Update Wizard screen is displayed
          select "Install from a list or specific location
          (Advanced)" and then click Next.

      8.  In the next screen "for choosing your search and
          installation options" select "Don't search.  I will
          choose the driver to install" and click Next.

      9.  Select "Have Disk" in the next screen.

      10. Click on "Browse" and point to the VfW INF file which is
          located in your PROGRAMFILES directory.  For example, 
          C:\Program Files\Osprey 540 and 560\driver\o540drv.inf.
          Click on "OK" at the top of the screen and then click Next.

      11. When the Windows Logo Testing dialog box is displayed
          select "Continue Anyway".

      12. Click on Finish.

      13. Perform steps 6-12 again for other AVStream devices 
          that you would like to set up for VfW.

IV.   In a mixed VfW / AVStream installation the audio mixer will
      always initially display the inputs for a VfW device, even 
      if an AVStream device should be the one selected.  User has
      to switch manually to the correct device using the mixer's 
      Options -> Properties control.

Limitations on Windows 2000
This driver may be installed on Windows 2000 with the
following expected limitations:

- No SimulStream audio.
- No peak level meter in the mixer (mixer may not work at all).
- Need to install DirectX 9.0a or higher.
- Need to manually create registry key to enable audio driver.
  To enable, set:
  to a non-zero value.

Windows XP Installation:
Depending on your system setup, you will have multiple 
options for the installation of the drivers.


Following are the different scenarios and their methods of

 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

 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.


 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 

 2. Select Destination Folders and Program Folders when

 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 AVStream Video Capture Device, then for the
 AVStream Audio Capture Device. This happens because Windows
 sees the audio and video sections of the card as two
 distinct logical devices. 

 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
 XP finds an Osprey card(s) installed, it will automatically 
 activate the driver.


 Run the Installation Program:
 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
 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
