Do you have any idea at all why it doesn't work? Maybe we can help you.

I have the 64-bit version of gstreamer-0.10 base plugins installed, and the 32 bit version does not show up in Synaptic. I hunted down a deb of the 32-bit version and tried to install by double-clicking it. It says that I have the wrong architecture, and it won't let me install it. Well, duh, I know it's a 32-bit package on a 64-bit machine, install it anyways, please. But it has no over-ride option.

Unless ChemDraw plays video or audio with DirectShow, not at all.

The short answer is that a 32-bit binary isn't allowed to call a 64-bit library (and vice-versa). If you want to use the 64-bit gstreamer, you have to use a 64-bit Wine.

The long answer has more to do with the differing code models of 32-bit and 64-bit binaries, and how, more important, you get in and out of 64-bit mode on an x86 CPU. I won't explain it here, but if you're interested, mail me directly.

This particular problem, however, could be a symptom of gstreamer pulling in the 64-bit glib headers (in particular, glibconfig.h). This causes issues, so now the configure script will complain if you aren't using the 32-bit headers. You need the 32-bit glib headers to use 32-bit gstreamer properly.

Yeah it did. It was just breaking silently before. Now it complains loudly.

You could always build glib and gstreamer from source :).
