Audacity Forum

Does audacity only need the libavformat.so library? If you install libavformat-dev then that should pull in all of the required parts of FFmpeg as dependencies.

I'm updating an old Debian install and shall get back to you later...

The instructions in the build.txt were written by developers for developers.
The instructions here on the help forum were written by me, for end users, and are thus detailed step-by-step instructions for a standard "release build".

Did you use the -Daudacity_use_ffmpeg=loaded option as described here: viewtopic.php?p=398471#p398471
