WDM support for nxtvepg (analog capture devices)
The WDM interface library was developed by Gerard Chevalier in 2004-2005. Afterwards it was maintained by the author of nxtvepg.
The following package contains the last release of the WDM interface library for Windows. It allows Windows users to optionally use drivers supplied by their card's manufacturer instead of the one which comes with nxtvepg. Note only analog capture cards are supported (i.e. no DVB).
Main goal of development was to help Windows users who cannot use nxtvepg at all because their TV card is not supported by nxtvepg's driver. In nxtvepg versions 2.x, VBI acquisition in the Windows port of nxtvepg was based exclusively on the DScaler "dsdrv4" driver, which supports only analog TV cards based on Conexant BT878, CX23881 or Philips SAA7134 (and even among these only the ones with supported tuners.) Cards with chip sets from vendors which do not disclose specifications to support open source driver implementations cannot be supported this way. Since nxtvepg version 3.0, WDM drivers are the only way to use TV cards under Windows, as the dsdrv4 driver was removed.
WDM support is useful for Windows users only. UNIX users need not look further.
Download latest release: July 23rd 2006
- Interface library: nxtvepg-wdm-dll-20060723.zip
- WDM Driver sources VBIAcqWDMDrvSrc081905.zip (Visual Studio 2002-V7)
Unpack the ZIP archive into the same directory as nxtvepg, i.e. the DLL should be in the same directory as nxtvepg.exe. Additional instructions see README-WDM.txt in the zip file.
Important note: To use the library you need version 70d of the Microsoft Visual C run-time library (i.e. msvcr70d.dll) For legal reasons it is not included here. There are however plenty of sources for it on the web, you can search for msvcr70d.dll with Google.
Known problems
The following bugs/open issues are already known:
- When initially selecting a WDM source in the TV card input configuration dialog, video source selection may not work (device is allegedly busy.) If that happens, just close the dialog with OK and open it again. After that the video input selection should work.
- TV channel/frequency conversion doesn't work for all channel tables yet.
If you live in Germany and have cable, you need to have a file named
VBIAcqWDMDrv.ini in the same directory as VBIAcqWDMDrv.dll with the
following two lines:
[Debug Behaviour] ForceRFInput=c
This file is already included in the package. - The EPG provider scan must be run in slow mode (you can enable this option at the bottom of the provider scan dialog window.) Even then some networks may appear duplicate in the scan. If your provider isn't found due to this, try running the scan again, or use a K!TV or DScaler channel table and move your provider's channel to the first position.
- Hauppauge PVR 250/350 cards are not supported yet.
Tests feedback
This section lists card and system combinations currently reported as "working".
- Leadtek WinFast TV2000XP Expert on Windows XP and Windows 2000
- Hauppauge WinTv PCI (Bt878 + Philips Tuner) on Windows XP
- Hauppauge WinTv Go on Windows XP
- Hauppauge WinTV PVR on Windows 2000
- Hauppauge WinTV PCI (new series with CX23881 chip) on W2K: works partly
Appearently due to a bug in the WDM driver apx. half of the teletext pages are lost; but if you're patient EPG reception is still possible. - Typhoon card "Art.No. 90031" with Philips capture chip (SAA7134) on W2K
- Almost any card with Brooktree Bt878 or Bt848 capture chip when using the free btwincap WDM driver.
