My DirectShow code have some problens.

I want to create the DirectShow filters by coCreateInstance funtion.

C++

WINOLEAPI CoCreateInstance(__in     REFCLSID rclsid, 
                           __in_opt LPUNKNOWN pUnkOuter,
                           __in     DWORD dwClsContext, 
                           __in     REFIID riid, 
                           __deref_out LPVOID FAR* ppv);

and it needs the filters clsid.

I don't know how to get the filter's clsid given by SDK like CLSID_VideoMixingRenderer. So I copy the macro and replace the numbers with my.
For example:

C++

//@device:sw:{083863F1-70DE-11D0-BD40-00A0C911CE86}\{D3588AB0-0781-11CE-B03A-0020AF0BA770}
//this is the avi/wmv file source filter moniker numbers  that comes form my graphedit.

OUR_GUID_ENTRY(CLSID_Sourcefilter_AVI_WAV,
      0xd3588ab0, 0x0781,0x11ce, 0xb0,0x3a, 0x00 ,0x20, 0xaf ,0x0b,0xa7,0x70);
x0b,0xa7,0x70);

i put these code in my player.cpp

and the complier reports error.

Can you help me?
thanks

Solution 1

Take out one of the close brackets and change the semicolon to a comma:

C#

OUR_GUID_ENTRY(CLSID_Sourcefilter_AVI_WAV,
      0xd3588ab0, 0x0781,0x11ce, 0xb0,0x3a, 0x00 ,0x20, 0xaf ,0x0b,0xa7,0x70);
x0b,0xa7,0x70);

Becomes:

C#

OUR_GUID_ENTRY(CLSID_Sourcefilter_AVI_WAV,
      0xd3588ab0, 0x0781,0x11ce, 0xb0,0x3a, 0x00 ,0x20, 0xaf ,0x0b,0xa7,0x70,
x0b,0xa7,0x70);
