CBaseVideoRenderer base class issues

Hi all. So I'm writing a direct-show camera capture class for
WindowsMobile 5. It's only purpose is to establish the filter graph
to capture a camera image and save it to a raw buffer.

So I intend to create a filter graph and attach a camera capture
filter and a custom VideoRenderer filter that I will be creating. The
VideoRenderer won't do anything except copy the captured frame to a
circular queue of raw buffers.

Everything was compiling and working up until I tried to get the
video
renderer to link. Here is my class decleration:

class TVideoRenderer : public CBaseVideoRenderer
{
//
// Member variables
private:
// GUID used to identify the direct show video renederer
static const GUID ms_guidVideoRenderer;


TCaptureDevice& m_rCapDevice;
DWORD m_dwPitch;
DWORD m_dwWidth;
DWORD m_dwHeight;

//
// Construction / Destruction
public:
TVideoRenderer(IUnknown* pUnk, TCaptureDevice& devCamera,
HRESULT*
phResult);
~TVideoRenderer();


//
// Public member functions
public:
HRESULT CheckMediaType(const CMediaType* kpMediaType);
HRESULT SetMediaType(const CMediaType* kpMediaType);
HRESULT DoRenderSample(IMediaSample* pMediaSample);



};


But when I go to link, I get errors galore. I've included the
following libs into my project:

dmoguids.lib
strmiids.lib
strmbase.lib
Uuid.lib


Here are the link errors.. if anyone could point me in the right
direction it would be so much appreciated!

Try setting ProjectSetting->C/C++->Language->Treate wchar_t as built in type
to "NO".
Hope it helps.

Also if only thing that you want to achieve is to Capture raw frame and write
it into some memory buffer then look at sample grabber.Sample grabber should
fit your requirement and also involves lot less work on your part..:-)

Well the problem now isn't the link errors it's when I go to
instantiate the newly created TVideoRender class. My app crashes
during the constructor which is in turn instantiating the
CBaseVideoRender class. I've read that I should be using the debug
direct show libs - specifically for strmbase.lib but as we all well
know.. there isn't a strmbased.lib under the WindowsMobile 5
platform... or is there? I can't find it if there is.

Here is my constructor code:

TCaptureDevice::TVideoRenderer::TVideoRenderer(IUnknown* pUnk,
TCaptureDevice&
dsDevice,
HRESULT* phResult)
: m_rCapDevice(dsDevice),
m_dwPitch(0),
m_dwHeight(0),
CBaseVideoRenderer(ms_kguidVideoRenderer, NAME("Video Renderer"),
pUnk, phResult)
{
ASSERT(NULL != phResult);

if (phResult)
{
*phResult = S_OK;
}
}

You can try downloading Windows CE 5.0 Evaluation Edition to get access to
shared source and debug and release libraries for your debugging purposes.
