videomode - rafael - 12-08-2011 08:12 AM
Hi guys,
I am using VLDSCapture to get image from my webcam. My webcam is Livecam HD from microsoft. All bitmaps i capture from it are in 640x480 resolution. How can i do to change the resolution ? I discovered the videomodes function but how to set it ?
Thanks,
Rafael

Hi! You can set the VideoSize->Width and height yourself. Make sure Current is set to false.

Look how is my code..
VLDSCapture1.Stop();
VLDSCapture1.VideoSize.Current := false;
VLDSCapture1.VideoSize.Width := 1024;
VLDSCapture1.VideoSize.Height := 768;
VLDSCapture1.Start();
and the resolution does not change..
i am using delphi xe2.

Looks ok, how do you capture your image?
RE: videomode - rafael - 12-08-2011 11:07 AM
I use to capture the picture
VLDSCapture.Outputpin -> VLGenericFilter.Inputpin
and the same VLDSCapture to show the image
VLDSCapture.Outputpin -> VLDSImageDisplay.Inputpin
but i need change the resolution, now is 640x480 and i need other better.
Any solution ?

How do you check it isn't 1024x768?
RE: videomode - rafael - 12-08-2011 12:15 PM
size of image in display.
the image is not streched or proportional.
and when i capture, i see size in property.

Maybe a driver issue then, perhaps Boian has some ideas here...

Which cam (model) do you have? It's possible the resolution you're trying to use isn't supported by the cam for streaming video.

it is supported.
