DaulCamera: OpenPreviewWindow com error Preview failed - W2K SP4
By: GerhardS Rank: Newbie Topics: 0 From: Germany	Added: 09/04/2007 - 12:30 AM I'm currently testing AbelCam with several USB cameras, e.g a DaulCamera or a Typhoon Motion Cam. But something general seems not to work. The cams can be configured successfully but will not start: 00:09:08 ------------------------------------------------------------------------ 09-04-2007 Started log 2.2.0 Release: 2007-08-11 00:09:09 Microsoft Windows 2000 Server\|C:\WINNT\|\Device\Harddisk0\Partition1 5.0.2195 IGSSRVHO System Name System Manufacturer X86-based PC 670601216 00:09:09 Listing available sound devices: Manufacturer \| Name \| PNPDeviceID \| ProductName 00:09:11 write_config 00:09:39 new form for DaulCamera-1 00:09:39 InitCodecs 00:09:39 Reading codecs from file C:\WINNT\Profiles\All Users\Anwendungsdaten\Seiz System Engineering\AbelCam\codecs.xml 00:09:39 done InitCodecs 00:09:39 vserver set frmvcx+vserverstruc 00:09:40 checkboxcam changed True 00:09:40 DaulCamera-1 start 00:09:41 OpenPreviewWindow com error Preview failed Error Code -2146827255 using Renderer vcxVMR9 00:09:41 fvcx(currentfvcxnr).BackGroundActive 00:09:41 Strange: cam DaulCamera reports not active but is connected 00:09:41 vserver set frmvcx+vserverstruc 00:09:41 DaulCamera cam.active false, stop timergrabframe Really strange is, that the cams run fine with other webcam applications like Dorgem for Fwink. Any ideas how to fix this problem? Or what is missing on this system? Thanks.

By: GerhardS Rank: Newbie Topics: 0 From: Germany	Added: 09/05/2007 - 12:22 AM Hello, according to DxDiag Version 9.0c (4.09.0000.0904), so the most actual version of DirectX available for W2K. I also checked system with DxDiag -> no problems found. The system has no sound card installed. Can this explain the problem?
By: sse Rank: Forum Addict Topics: 73 From: n/a	Added: 09/07/2007 - 08:29 AM Gerhard, to figure out if it's the Audio part of the software causing problems, you may start AbelCam with the 'AbelCam without Audio' Startmenu entry (in Tools). Also, you may want to try the latest version, which uses a new OCX which might resolve this. See AbelCam Issues for this release.
By: GerhardS Rank: Newbie Topics: 0 From: Germany	Added: 09/10/2007 - 01:20 AM Stefan, a strange thing happened. After adding more memory to the system (from 640 MB to 1 GB) AbelCam starts the camera successfully. So far it looks fine. But while AbelCam is running the CPU Load is permanently at 100 %. Just stopping the camera the CPU Load returns to normal. This happens with version 2.2 and 2.2.1. and also when running AbelCam as a service. While using the same camera with Dorgem the CPU Load increases shortly when an image is captured. However, turning on the Preview Window also causes a CPU Load of 100 %. Is this possibly a camera driver or an USB interface issue? Would it be possible to turn the Real Time Preview feature off?
