Launching Audacity 2.1.0-alpha, Audacity loads FFmpeg correctly from "C:ffmpeg for audacity":Ĭode: Select all 14:28:48: Audacity 2.1.0-alpha-Dec 4 2014ġ4:28:57: Trying to load FFmpeg libraries.ġ4:28:57: mLibAVFormatPath ('C:ffmpeg for audacitybinavformat-55.dll') is not empty. I added "C:path test" to the system PATH and rebooted. That DLL is useless as the other shared libraries are missing. Then I created C:path test and added only "avformat-52.dll" (a valid file from FFmpeg 0.6.2, but 0.6.2 is incompatible with Audacity 2.1.0). Still, I created "C:ffmpeg for audacity" without installing FFmpeg and pointed Audacity in Libraries Preferences to "C:ffmpeg for audacityavformat-55.dll" and exited Audacity. Those are not exact steps to reproduce, because I don't know if you installed FFmpeg to "C:ffmpeg for audacity" (which sets a registry key). (i created a dir c:test and added it to the path) Create a empty/different/invalid dummy file named "avutil-52.dll" somewhere inside the PATH trail. In Audacity options set your ffmpeg folder truthfully to (for example) "c:ffmpeg for audacityavformat-55.dll" and close Audacity.Ģ.
