I installed the FFMPEG library as per instruction on the wiki, using the Audacity 3.1.3 and FFmpeg 2.2.2

I also tried on installing the library on both Program Files and Program Files (x86) and the results are still the same

  1. So you are going through the motions. The first thing to do is determine whether you have a 32-bit or a 64-bit of 3.1.3 Audacity installed. To do this, Help > Audacity > Build Information. The third line under “The Build” tells you whether you have 32-bit or 64-bit Audacity. Now, your version of FFMPEG must agree with that of the Audacity build.

  2. If you have 64-bit Audacity, then go here: https://lame.buanzo.org/ffmpeg64audacity.php. Ignore all the ads to download all kinds of cool software and locate and click on the link: “FFmpeg v2.2.2 INSTALLER (.EXE)”. This will be installed on C:\Program Files\FFmpeg for Audacity.

  3. For 32-bit Audacity, go here: https://lame.buanzo.org/#lamewindl and download “ffmpeg-win-2.2.2.exe” (search for it). This installs to C:\Program Files (86)\FFmpeg for Audacity.

I had the same issue and it turned out that I had the 32 bit version of Audacity. I uninstalled it, and downloaded and installed the 64 bit version, and now it worked. What was confusing is that Help > About > Build Information does NOT say “32 bit” in the 32 bit version, so if it says 64 bit it’s 64 bit, and if it doesn’t say 64 bit it’s 32 bit.

I stand corrected. Thank you for your report. :smiley:
