I'm not sure about the first line, but the rest of it is Audacity trying to find FFMpeg but not finding it.
FFMpeg is an optional add-on for Audacity that provides support for importing and exporting many different audio formats.

If you want to install FFMpeg, see here: http://manual.audacityteam.org/index.ph ... tallffmpeg

There are a lot of possible configurations that Audacity needs to check through (remember that Audacity will run on almost any computer).
The Errors are configurations that Audacity has tried that have failed,
but then see:

Code: Select all

18:04:29: Loading avutil from 'C:Program Files (x86)Ffmpeg For Audacityavutil-50.dll'

Audacity has found the first part of FFMpeg and loads it.
Follow the list down from there .... no more errors,
then the final line:

Code: Select all

18:04:29: FFmpeg libraries loaded successfully.

Congratulations you have correctly installed FFMpeg.
