Scott,
I'm sure you are right :) But imagine a mounted Pocket PC or Smartphone used as a 'cheap' security device sending images to a web server. For example, if you are a student using a shared fridge, stick your device to the inside door and catch the thief steeling your milk. Could be a lot of fun!
Or use the device for time laps image capture on a construction site.

Hi Marcus,

I am finding that some win mobile 5 devices just wont run the Directshow TimedCamera code. Have you found the support of cameras under winmob5 not as standardized as it was supposed to be?

On the devices that do run it, I am having a real fight setting the image size, can anyone point me the right direction :-)

re: Timed Camera Capture

Simon — Wed, 26 Apr 2006 18:21:39 GMT

Hi there!

This code is exactly what I have been trawling the web for! I need to make an application that will stream images from a Windows Mobile 2005 PocketPC (HTC Universal) to a web service so that clients can then view the "latest" image. The standard Camera dialog is not suitable to the user intervention it requires, and my C++ knowledge is practically none-existent, so this wrapper for it is ideal.

However, I have run into a problem with it. I have got the code working fine on the device, but every time I get a response from the camera of "Error from capture" and am unable to identify why. (This is in the ResponseToMessage method, in the switch statement, at the line "case (int)DSHOW_MESSAGE.MESSAGE_ERROR:".

I was wondering if you had any ideas why this might be, or could point me in the right direction?

Cheers!

typedef BOOL (*fnCaptureStill)(TCHAR szfile[MAX_PATH]);

BOOL CamCap()
{
INSTANCE hCam = LoadLibrary(TEXT("CameraCaptureDLL.dll"));
fnInitializeGraph funcInitializeGraph = NULL;
fnCaptureStill funcCaptureStill = NULL;

funcInitializeGraph = (fnInitializeGraph)GetProcAddress(hCam, TEXT("InitializeGraph"));

if (funcInitializeGraph)
{
funcInitializeGraph(hWnd);
}
...

Thanks for this code sample. I tried it out on my new Cingular 8125, and it works like a charm. However, I have only one problem: the still images it takes are always 160 wide X 120 pixels high, and I can't seem to find any way in your code to set the image size.

The phone has a 1.3 megapixel camera, and when I use the built-in picture taking program, 160X120 is the smallest size available, with a couple other bigger sizes including 1240 X 760 or something high resolution like that.

Do you know of any way to set this picture size? Thanks.

re: Timed Camera Capture

Arjun — Fri, 23 Mar 2007 22:28:07 GMT

Hi,

I am using the modified DirectShow Camera Capture sample for capturing the Video from my Win Mobile device. Now my problem is that I want to capture it direct-to-disk using directshow (so that the user can see real-time increase in size of the captured file and should also be abel to preview the file midway in between (using the local media player), while recording is still going on).

I could easily capture the video from the win mobile camera, and also the associated Audio. But it gets written to an asf file in the specified location, only after I manually stop the capturing by click of the Stop button on my custom interface. My need is that the captured audio and video keeps on getting written to the asf file continously as i capture, without depending on user input to stop the recording. This means that on start of the camera capture, a file should be instantaneously created in the specified location, and captured video/audio keeps on getting written frame-per-frame to this file and the file should keep on growing in size with the progress in capturing.

Please let me know how to do that, since I could not find anything on the same.

Please mail me if you got any solution on this at arjun.bahree@gmail.com

Thanks in Advance

Hello,

Many of you ask how to change the resolution of the image taken. I think following line of code should do it for you:

camera.Resolution = New Size(640, 480)

where camera is an object of class CameraCaptureDialog.

Cheers

re: Timed Camera Capture

Daniel — Mon, 03 Sep 2007 23:24:29 GMT

I didn't belive it helps - nevertheless I tried ;)

Code like this:

Doesn't help me with changeing the resolution!

Any other Ideas?

re: Timed Camera Capture

Herman — Wed, 05 Dec 2007 09:23:56 GMT

Resolution for "Can't find PInvoke DLL 'CameraCaptureDLL.dll"

It is during deployment of the app to your phone/pda that this file is not getting copied. That's why when the app executes, it can't find the file -- it was never there to begin with.

A solution is to add this file into your VS.net 2005 project. in Solution explorer, right-click the project and choose Add>Existing Files, then select the CameraCaptureDLL.dll.

Once the file is added, check the properties. It should say that the file is considered as 'Content'. Set the option to Copy to Output Directory All the Time.

Rebuild and re-deploy. The error should now disappear.
