Osprey-1000 Audio/Video Capture/Compression/Decompression Board
Windows Release 2.60 x86
Video Capture Driver Patch (oti1kvc.dll)
08/98

Patch Notes:
============

This patch fixes a bug in H.261 parsing discovered by Lucent Technologies.
It was generating the wrong MQUANT and motion vector info.  This has been
corrected.

This patch also provides a new feature, the MMAC_OVERLAY_DELAY_SET message.
This message has been added to the Video Capture driver to allow the user
to set the Overlay Refresh value.  This value is stored in the registry as:

HKEY_CURRENT_USER\Software\Osprey\Osprey1000\Device0\VcDll\User\OverlayDelay


This is a subfunction of the MMAC_O1K_CONFIGURE driver message.  It accepts
1 parameter (the lParam2) as the new value of the Overlay Frame Rate.  It
(unlike the other control panel mods) will use the new value immediately and
adjust the value in the registry shown via the Osprey-1000 Video Capture
Settings dialog.
