Ligos has no plans to port the Indeo 5 to the Mac OS X platform. (see http://ligos.com/pdf_docs/Indeo_doc.pdf)
The Apple site describes a workaround though:
You have to reboot into Mac OS 9 (is this available to all Mac OS X users, or only to those who upgraded from 9 to X?) then possibly download the codec from that page.
Another thought that hit my mind was you could try mplayer for mac os x. I believe mplayer was originally developed on linux and is like xanim in that it can use windows dll’s to decode videos in a specific codec.
No, it won’t work.
You’ll need to have “Classic” (Mac OS 9) installed.
If you have an Intel Mac - use BootCamp and boot into Win XP, these files play nicely in Windows Media Player.
The “Classic” environment doesn’t work with Intel Macs.
Not a Mac-only solution: But I managed to convert all of my older .avi (IV50) footage to MP4 using Need4 Video Converter for Windows (http://need4video.com/). It costs a few bucks - but it enabled my video in the ancient IV50 format to be converted to the more future-proof MPEG4 format. The MPEG4 files are easily displayed in Quicktime on both Mac and PC.
The Anyvideo converter worked great: converting an IV50 Indeo avi to mp4. The file size is about 25% of the original (and of course the enlarge quality suffers), but it plays a views perfectly on a Macbook Pro OSX within Quicktime.
The conversion is slow, but if you are converting a bunch of avi files, just throw them on the list and let the program do its work. Just to be safe try one file first and then view. If successful put the rest on the list and let it run.
