Flix Engine COM

---

Detailed Description

The COM interface provides a thin wrapper for access to non-deprecated Flix Engine functions.

Usage Notes:

• For consistency with COM, all Flix Engine COM functions return an HRESULT. The on2sc returned from the corresponding Flix Engine function is therefore mapped to an HRESULT:

       HRESULT hr= MAKE_HRESULT(SEVERITY_ERROR, FACILITY_NULL, sc);
  

  Should the language not provide access to the HRESULT returned from the function, the sc property within each interface stores the last return code.
• For consistency with COM, all strings are represented using a BSTR. Some Flix Engine functions, however, only support ASCII strings, i.e. those defined as taking a char* rather than an on2tc*. In this case the value passed to the interface will be converted before the call is made. Check the notes associated with the interface for further details.
• Enumeration values should be available as constants if the language has the ability to extract them from the type library, cf. samples.
• String constants (e.g., filter/codec names/params) are available as properties within flixengine_com::IFlix. The documentation for each property refers back to the corresponding filter/codec.

Attention:

flixengine_com is a dual interface, meaning it exposes methods and properties via IDispatch as well as directly through the VTBL.
If using a language that supports direct VTBL binding (e.g., ASP.NET, C#, VB.NET) the assembly file, Interop.flixengine_com.dll, provided in %PROGRAMFILES%\On2 Flix Engine\lib will need to be updated should the major (M) or minor (m) version (x.M.m.x) of the COM library increase. If the application is based on the C++ sample it will need to be rebuilt in this case, flixengine_com_i.c being an analogue of the Interop.flixengine_com.dll assembly.
