Grabbing uncompressed frames from a stream

Mar 4, 2009 at 12:10 PM
Hi all,

At this moment I'm trying 2 applications to display the webcam video streams. The first app is the camtest3 which gives the following error:

WebCam: Error calling IssueVendorTransfer rc: 1460  ExtErr: 1460
WebCam: Error calling IssueVendorTransfer rc: 1460  ExtErr: 1460
WebCam: Error setting original probe vals  rc 1460
WebCam: Probe/Commit failed.  Not enough bandwidth for Fmt: 1  Frm: 1
failure calling IOCTL_CAMERA_DEVICE_STARTVIDEOSTREAM rc 1460
ReadFrameThread--


A query gives the following settings from my CAM:

WEBCAM: pddvClas: ProcessFrameFormats:
  cbSize:          68
  wFormatType:      5
  wFormatIndex:     1
  wFrameIndex:      1
  dwWidth:        320
  dwHeight:       240
  dwMaxBuff:    153600
  nNumInterval:    -1

And I'm using WinCE 6 with a OTG port.



My second application is very simple one that only calls the necessary for streaming video. The stream is started but after the getting the first frame I get the following error:

WebCam: Next Frame event not signaled rc 258

Can anyone help on one of these problems?

Actually the problem was that the device was using Bulk as transfer mode.
