Thanks for the reply. I'll try to clarify.
First of all, I'm using version 0.9.6. I'm not using mlt++ precisely
because of the C++ name mangling problem. I'm using the Hello World example
from http://www.mltframework.org/bin/view/MLT/Framework (with minor code
changes to adapt to VS and because mlt_factor_init usage apparent changed
since the page was written and 0 signified failure, not success). My code
is in a C++ file but the calls work well enough (apart from the crash).
If MLT on Windows is generally untested, I guess I'll stay away from it for
now (my current needs don't require something as powerful as MLT). Even
compiling it wasn't totally smooth sailing (had to change the way macro
varargs are defined in mlt_log.h to the Microsoft way).
