Hi
I am working on a set of FxPlug filters for use in FCP and Motion.
The bulk of the code in these filters consists of a large
pre-existing library of C++ code. There is a relatively thin layer
of Objective C code, (along with some utility code written in C++)
wrapped around the old library. All of the common Objective C classes
are given unique names (for each filter) at precompile time.
What I am finding is that certain filters interfere with other
filters when they are installed. This happens particularly in debug
builds. (I'm not sure its completely restricted to debug builds -- if
it were, I could work around it if necessary.
What I am seeing is situations like
1. If filter A is installed, FCP will crash (in its own code)
when filter B brings up its UI, even if filter A is not used in the
session
2. If Filter C is installed, Filters D and E will not render
correctly, even if filter C is not used in the session.
I realize this is sketchy information, but I'm hoping someone on one
of these lists has an idea about how to deal with the problem.
Thanks.
