I wrote a console32 app on a PC a while back and I need to update it. Basically, it converts an .avi to a series of .bmp's and custom formats. Now I've got an .avi where the source asset is gone and it appears to be DivX (or MP42 which isn't really important). Since I'm able to play it the codec is obviously installed.
In the past I simply called AVIStreamOpenFromFile()and AVIStreamGetFrameOpen() which now returns an error. I've since tried a variety of functions including ICLocate() which tell me no decompressor is installed. Now I know it can be done but I also know it's not easy. Most commercial software cannot handle the file, Premiere, TMPeg, etc. But older Paint Shop Pro 6 can for some reason. So they are obviously doing something the others and I are not.
I also swear I decoded the same file 2 months ago, so either a change in the codec or a Windows Update media change broke it.
So, I know asking here is a long shot, but does anyone know an online resource for Windows coding crap like this?
Thanks,

Re: Needing help or an online source
Fri, October 17, 2003 - 3:07 PMI've now determined NOTHING works. While Paint Shop Pro 6 Animation Shop may have worked at one time it doesn't now. I now believe this may have something to do with MS updates to/for Media Player, Windows Media and possibly updates to the codec itself.
Since video plays on an overlay plane, you can make a codec that can play but does not allow the user to extract the data. This would be due to the overlay plane being a write-only surface and setting or forgetting to set capability options in the codec which are possibly now present for DRM or trusted computing.

Re: Needing help or an online source
Fri, October 17, 2003 - 6:06 PMI've now determined the problem. It was my failure in not enumerating all the codecs that could handle the .avi and then selecting the one that did what I wanted. Thanks to a free util called GSpot was able to easily show the codecs installed on various PC's, one which actually worked. No surprise the MS codec didn't.
