View Full Version : MP3 codec for AviSource

I had my Windows codecs scrambled by someone (not me) installing some random video app.

I got rid of it but was left with some problems.

I installed ffdshow and that allows me to view just about anything, and is invoked by DirectShowSource().

However, 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 were fine.

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

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

If anyone else comes across this, my solution was

l3codeca.acm was in the system32 folder and was unregistered

I ran:
regsvr32.exe "D:\WinNT\system32\l3codeca.acm"
(Use your own pathname.)

And now it's registered and AviSource works with MP3.

To repair other built-in Windows codecs, try downloading and installing the K-Lite Codec Tweak Tool and setting it to re-register all of the base codecs.

K-Lite? Really?

:(

You can just get the LAME ACM codec

No, not the codec pack, the codec tweak tool. It's a separate tool. Come on, I'm not about to recommend codec packs to people :rolleyes:

I already had the ACM files, the problem was they weren't registered. I gather the tweak tool can do that.

I also had the Lame ACM, but I believe it's for encoding, not decoding, so it didn't help.
