I followed the recommendation to compile the sources, and was successful with MS Visual Studio C++ 2010 Express. There was no problem with the custom project file. Still, it seems like a waste to install MSVC++ 2010 just to build a single DLL.
If you don't want to go through the hassle, you can use Sodira. If you don't really like the interface (and I don't), copy the included libfaad2.dll into your Dream directory, and rename it to faad_drm.dll (and it must be faad_drm.dll, not faad2_drm.dll).
I've tried it and can confirm it works, although the DLL size is a couple kilobytes larger compared to the DLL I compiled myself (229 KB vs 232 KB). Yeah, it doesn't matter.
I also tried the pre-compiled libFAAD2 2.7 DLL from Rarewares, and it crashes Dream, so don't use that one. But you could try your luck with a 2006 build of Dream, listed at the bottom of that decoders page.
A couple notes about building a DLL, just so I can reference it in case I forget:
- Yes, you should really download faad2_project_files.zip
- I used faad2-2.7.zip, not that it matters
- Unzip faad2_project_files.zip into faad2-2.7/libfaad
- Open the 2010 solution file
- Switch build target to Release
- Build and rename faad2_drm.dll to faad_drm.dll. They could have renamed the build target if they were going to make a custom solution file.
