Audacity and FFMPEG on Mac

[reemas]

might be a stupid question, but when i click on Find Library in the FFmpeg preference section of Audacity 1.3.6a6, I cannot go to the folder where FFmpeg was installed:
/usr/local/lib/audacity

How do I point it there, as it doesn't show up?

Also, of the several files in that folder, which is the correct FFmpeg one? Thanks in advance.

I would do this with the latest 1.3.7a development build following these instructions. That version of Audacity will be looking for libavformat-52.dylib.

I need to export my audio as AAC file so i followed the instruction given in the program to download the FFmpeg plugin. I am using version 1.3.7 of Audacity and the installation said it was successful. In preferences i located the "libavformat.52.dylib" file and pressed ok. Still however the program says it cannot locate the library and i am unable to export. The file address location is correct! i have tried restarting the program and installing the plugin again, still nothing. What should i do?

Audacity has been updated several times since Gale's post.
Try the latest version of Audacity from here: http://www.audacity.homerow.net/index.php?dir=mac%2F

Perfect! I downloaded 1.3.8b and it works fine now.

Thanks for your help.

Thank you Josh24 for your post. With your advice, I was able to get farther compiling ffmpeg than with anything I could Google on the web. My situation may be unique in that I am on PPC Tiger 10.4.11. As you can probably tell from my uninformed scatter-shot query, I hit the wall quickly when open-source downloads do not compile.

My question is: Is there some kind of option I can set, or some files I can modify in my ffmpeg-checkout-2009-09-03 directory that will allow me to push through the make?

ld error during make:

ld: -dylib_compatibility_version must be greater than zero
