Cannot load ffmpeg libraries

sadlof · May 30, 2014, 3:09pm

I am running Audacity 2.0.5 on a Windows 7 PC. I am attempting to download the FFmpeg libraries, but Audacity says it can’t locate the library. I try to manually locate the path at C:ProgramFiles(x86)LameforAudacitylame_enc.dll. When I then tried to import a WMA file, I got the returned message “Audacity attempted to use FFmpeg to import an audio file, but the libraries were not found.” The Help Log is pasted below.

Thanks for any help you can provide.

If I had to guess at it, I’d say Audacity doesn’t have permission to go down that pathway. We need to wait for the WIndows elves to appear.

The instructions are here: http://manual.audacityteam.org/o/man/faq_installation_and_plug_ins.html#ffdown .

You appear to have installed FFmpeg in C:Program Files (x86)Lame For Audacity or at the least, pointed Audacity to lame_enc.dll when you opened the Libraries Preferences and pressed “Locate…” for the FFmpeg library. Try opening the Libraries Preferences, press “Locate…” to the right of “FFmpeg Library”, then “Browse…” then select and open “avformat-52.dll”.

If that doesn’t work, uninstall FFmpeg then install it properly into C:Program Files (x86)Ffmpeg For Audacity and restart Audacity.
