On my Win2008 dev machine, I'm making use of NAudio's DmoMp3FrameDecompressor. It makes use of the following DMO:
MP3 Decoder DMO ({BBEEA841-0A63-4F52-A7AB-A9B3A84ED38A})
On an XP machine, playback is failing because this DMO is not present on the system. I'd like to know:
Where does this DMO come from?
It seems to be on most versions of Windows from Vista onwards
Is it possible to install it in XP? The naudio source code indicates that it should be possible.
I don't think so. Why do you think the NAudio source code indicates this? On XP you should use the ACM MP3 decoder,
Which Microsoft package includes it?
None that I know of. If you're on Windows Server, make sure the desktop experience is installed
Is it possible to add it to my installer as a merge module?
Don't think so I am afraid. There tend to be strict licensing conditions about redistributing MP3 decoders.
