Release Notes
Version 1.2.50 (August 2023)
FAdd new deinterlacing functions S2253_GetDeinterlaceMode and
S2253_SetDeinterlaceMode. Deinterlacing uses a hardware
algorithm to smooth motion between two video fields that is visually
more appealing than Interpolate mode, with a few limitations (see
function description for details).
Version 1.2.49 (April 2023)
FVideo renderer change for Windows 11 only. Default will be VMR9
if supported due to some issues with 64-bit VMR7 on Windows 11
(April 2023).
FEVR renderer previewtype added to S2253_SetPreviewType
enumerations.
FDemo application allows changing the video renderer for test
purposes (Default, VMR9, VMR7, EVR).
FBug fix for FPS display under VMR9.
FBug fix for switching between null and non-null windows with
S2253_SetVideoWindow.
Version 1.2.48 (June 2022)
FDriver bug fix for use of the 2253 with some newer video cards.
Please update if experiencing driver crashes when previewing the
video stream.
Version 1.2.47 (April 2022)
FFixed custom size of 768x576 for PAL video system. Fix includes
driver, DLL, and demo application changes. Also adds 768x576
data-range enumeration for standalone DirectShow applications.
FThere is a known issue with the demo application only. For the PAL
video standard, the preview/record size of 720x480 should display
as 720x576. If 720x480 is desired with the PAL video standard,
please use the custom size dialog in the application.
Version 1.2.46 (February 2022)
FDriver fix for 32-bit processs/application on 64-bit Windows. There
was a bug where the 32-bit proxy was not being registered the first
time the device was installed on a PC. This would cause the 32-bit
demo to fail loading (on 64-bit Windows only).
Version 1.2.45 (December 2021)
FWHQL Windows secure boot update for Win10/11.
Version 1.2.44 (November 2021)
FDriver update
Version 1.2.43 (November 2021)
FDriver update. Older driver cleanup fix. Win10 driver renamed to
win_secureboot (usable for Win10 and Win11). Win secureboot
driver not updated at this time.
Version 1.2.42 (August 2021)
F2253 filter display name (aka friendly name) changeable via
DIPswitch. Default is still Sensoray 2253 Capture A, or Sensoray
2253 Capture B, but other switch positions will append the switch
position to the filter name. The appended DIP switch setting is not
zero indexed.
FFor easier identification of multiple boards (up to 4) in the system.
FUse S2253_GetDIPSwitch to retrieve the current DIP switch
position.
FDIP switch 0: Sensoray 2253 Capture A, Sensoray 2253 Capture B
FDIP switch 1: Sensoray 2253 Capture A #2, Sensoray 2253 Capture
B #2
FDIP switch 2: Sensoray 2253 Capture A #3, Sensoray 2253 Capture
B #3
FDIP switch 3: Sensoray 2253 Capture A #4, Sensoray 2253 Capture
B #4
