MP3 codec for AviSource?

[AlanHK]

I had my Windows codecs scrambled by someone installing a random video app.
I got rid of it but was left with some problems, specifically with AviSource in Avisynth.

If I now use AviSource() to open an AVI file using MP3 audio, it comes up with an error:
"The requested conversion is not possible".
Previously these worked fine.

I installed ffdshow and that allows me to play just about anything, and is invoked by DirectShowSource(), but AviSource can't use these and still gives the same error.

What do I need to install/enable so AviSource can handle MP3?

This is in Win2k, but most things work the same as XP.

did you try re-installing a mp3 codec?

I think it's Lame ACM that you're looking for

Maybe re-registering quartz.dll? Or l3codeca.acm, l3codecp.acm, or l3codecx.ax?

l3codeca.acm was in the system32 folder and was unregistered
in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32.
-- Looking inside the file it's apparently the Fraunhofer MP3 decoder.
(lameACM.acm was already registered though.)

So I ran:
regsvr32.exe "D:\WinNT\system32\l3codeca.acm"

And now it's registered and AviSource works.

Thanks!

LameACM is only an encoder.
