Constructing Directshow filter graph manually to read an ASF file on network on WinCE

Constructing Directshow filter graph manually to read an ASF file on network on WinCE

Hi all,

I have written my custom ASF parser filter. This filter I can connect
in a filter graph avoiding Windows media source filter. I have been
able to play a local file.

The procedure:

1. Create instance for CLSID_AsyncReader source.
2. Add source filter to graph
3. Load local file
4. Create my ASF parser filter instance.
5. Add parser filter to graph.
6. Get source output pin
7. Render source output pin
8. Run the graph

Now for playback over URL I am trying to create instance of
CLSID_URLReader.
But it is not getting created on WinCE.

Does anybody have any idea how to create filter graph to read over
URL.
I am doing this development for WinCE.

Thanks,

Rishi

    HRESULT hr = CoCreateInstance(CLSID_URLReader, 0,
CLSCTX_INPROC_SERVER,
        IID_IBaseFilter, (void**)&pSource);

 But it is not getting created on WinCE.

CLSID_URLReader is supported on WinCE, but not support on Windows Mobile.

Or, When you built the OS Image with Platform Builder, You didn't add it.

I tried to add the URLmon to OS image, but still the call,

HRESULT hr = CoCreateInstance(CLSID_URLReader, 0,
                                             CLSCTX_INPROC_SERVER,
                                             IID_IBaseFilter,
(void**)&pSource);

fails.
I am doing this development on WinCE 5.0. Could you please the Catalog
components required to get it working.
It would be of great help.
