I am trying to encode an array - representing an image, of course - to another one with the LEAD MCMP/MJPEG codec (evaluation version). To do so, I create a IltmmConvert *g_pConvert object, where I select the MCMP/MJPEG compressor. Then, I set g_pConvert's source and target, with put_SourceArray and put_TargetArray, with the safearrays I have created. This is where I call StartConvert on g_pConvert, but before that, if I check the object's state, it's always in the state "not ready". What I am supposed to do to make it ready ? Did I forget something here ? Thanks by advance, Emeric    Report

But that's not what I want to do.I think the safearrays I use are correctly initialized (put_SourceArray and put_TargetArray return S_OK), so I don't get what's happening. Has anyone got an idea ? Thanks Emeric    Report
