Hi
I have downloaded the SDK over 4 months ago now or so... I am trying to export HD VANC CDP 608 and DTVCC (EIA-708b-1999 spec) data to an AAF file. There is no C++ sample that shows how to do this in the SDK.
I have made my app and tried it by calling CreateEssence but I'm not sure what codec or other parameters to use:
Code execution throws an exception AxEx ex.what() shows nothing.
I drilled a bit more and the exception comes from here:
(from c:...\AAF-src-1.1.6\AAF\ref-impl\src\impl\ImplAAFEssenceAccess.cpp)
plugins = ImplAAFContext::GetInstance()->GetPluginManager(); // plugins is set to 0x00470840
//!!!Handle case where multiple codecs exist for a codecID
CHECK(plugins->GetPluginInstance(_codecID, &plugin)); // this line throws the exception
_codecID is set to:
Data1 = 0x568fb761
Data2 = 0x9458
Data3 = 0x11d2
Data4 = 0x004f922c
I just don't know what those parameters should be for my VANC data to export to this AAF file. Bit mad at the moment...
Any help appreciated,
Bodi

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I suspect that CreateEssence fails because it needs a valid codec ID (different from kAAFNoCodec). I have no idea though what it should be in your case. I prefer creating the SourceMob and EssenceData objects directly rather than using EssenceAccess.
