CMMFFormatImplementationInformation Class Reference

class CMMFFormatImplementationInformation : public CMMFPluginImplementationInformation

Contains format support information retrieved from the ECom registry.

An object of this type may describe either a concrete format plugin (ie a CMMFFormatEncode or a CMMFFormatDecode implementation) or a format supported by a controller plugin.

The object is created using a CImplementationInformation object retrieved from the ECom registry. All relevant data is copied out of the CImplementationInformation object, and its opaque data is parsed to provide the supplier, supported media ids, supported mime types, supported file extensions, and supported header data matches.

Notes for Format Plugin developers:

The opaque data section of the ECom plugin resource file must be in the format:

opaque_data = "<?>Data 1<?>Data 2<?>Data 3<?>Data 4[...]<?>Data N";

The <?> preceding the data determines the meaning of the data.  The following are the possible tags:

	<s> - Supplier
	<i> - Media Id
	<m> - Mime Type
	<e> - File Extension
	<h> - Header Data
	<c> - Custom Interfaces

UIDs must always be in hex in the format '0x12345678', must include the '0x' and be 10 characters long
