Segmentation faults with Lame 3.96.1 -- help!

cdhgee · 05-21-2006, 09:34 AM

I'm trying to convert a WAV file to MP3 using the LAME encoder (version 3.96.1, which I believe to be the latest). Every time I try it, it segfaults. I've tried it with lots of different WAV files, so I know it's not the file that's causing it to fail. I've run it through gdb, below is the output.

I've tried googling for this, and have found a couple of other instances where people have got the same problem, but no suggestions as to what might be at fault.

I've also tried various different command-line arguments: none, --preset standard, --alt-preset standard etc, all to no avail.

Can anyone help?

You might want to download the source code and compile the program on your system. If you go that route and the program is not a single instance standalone program, you might also want to build the result into an RPM that you can install and/or uninstall with your package manager.

Thanks, xode, I'll give that a try.

Yeah, a new copy of lame did the trick - thanks.

Were you able to build it into a package or did you need to build it into a package?

Actually, I just removed lame, and reinstalled the rpm off the Fedora download site. Not sure why it worked this time - maybe the original rpm was corrupted or something. Anyway, it works now :-).
