Replacing the WMV ASF Writer with a custom filter (Windows Embedded CE 6.0)
1/6/2010
This topic describes how to add your own multiplexer filters and file writers so that they can be accessed in the Capture Graph Builder.
You have two options when writing Multiplexers/Filewriters:
- Implement the Multiplexer (Mux) and the file writer in separate filters.
In this case, the file writer should implement the IFileSinkFilter Interface and the IFileSinkFilter2 Interface, not the mux filter. You will need to add the FileWriter registry value as shown: [HKEY_CLASSES_ROOT\CLSID\{Mux Filter CLSID}]\FileWriter = “{File writer’s LCSID}”. - Implement the Mux and file writer in on filter.
Implement the IFileSinkFilter and IFileSinkFilter2 in the mux filter.
