Hi-
I have a virtual machine application that generates AVI movies. I use
the library from:
http://www.kilvarock.com/freesoftware/dlms/avi63plus.htm.
Should these same routines work to generate AVIs which play on a Mac?
My other problem is that I don't have access to a Mac, so it is almost
impossible for me to tinker with this stuff.
Thanks in advance for the help,
Dan

Yes. I was afraid that would be the response. /dan

There is an ffmpeg DLM for FL. You can get the source code from
http://web.interware.hu/fl/ffmpeg.cc
It has a BSD-style licence, so it is almost totally free. You can convert
it to an IDL DLM, if you have a working ffmpeg library for Mac OS X.
The ffmpeg homepage is:
http://ffmpeg.mplayerhq.hu

Well, there's simply no way that Ronn's avi writer will work on a
Mac. The dll relies on Windows to run the codec to encode the avi.
Someone might be able to write a dll (is that what it's called -
perhaps shared library) for Linux and/or Mac if there is an API for
those systems.
Is that what you're asking?
