audacity 2.1.3 can't use ffmpeg 3.3.2 avformat-57.dll

Downloaded audacity 2.1.3 portable.
Downloaded ffmpeg 3.3.2 shareable, both 32bit and 64bit, portable, from http://ffmpeg.zeranoe.com/builds/
Got ffmpeg link from https://www.videohelp.com/software/ffmpeg “view developers site”.
Went into Audacity → Edit → Preferences → Libraries and clicked ‘Locate’ for the ffmpeg library avformat-57.dll;
Navigated to my location and selected it, but it did not work.
Tried both 32bit and 64bit.

Does Audacity require v55 ie avformat-55.dll?
If so, the oldest version at zeranoe.com is v3.2 and it has avformat-57.

2 log files below:
For the 32bit ffmpeg avformat-57.dll
and the 64bit ffmpeg avformat-57.dll

If you mean the PortableApps version of Audacity, that is not our product and we are not able to offer support because we don’t know what modifications they have made. Contact PortableApps for support.

On the other hand, you can download the ZIP version of Audacity via the Audacity website (Audacity ® | Download for Windows) and use that as a portable version by creating a “Portable Settings” folder in the same location as the audacity.exe file (see: Missing features - Audacity Support)

For the official version of Audacity, see here for information about supported versions of FFmpeg: FAQ:Installation, Startup and Plugins - Audacity Manual

If you use the Audacity ZIP file supplied by us, it supports maximum of FFmpeg 2.3.x for loading through Libraries Preferences. Use our recommended FFmpeg installer: http://manual.audacityteam.org/man/installing_and_updating_audacity_on_windows.html#winff.

Alternatively you can export (not import) using arbitrary versions of ffmpeg.exe using Audacity’s command-line exporter.

Yeah, I read that, just didnt think it could be correct.

To be explicit:

The manual Installing and updating Audacity on Windows - Audacity Manual section “Installing the FFmpeg Import/Export Library on Windows”

Says to

Go to the external download page
Left-click > this link> , do not right-click.

“this link” is http://lame.buanzo.org/#lamewindl

The FFMPEG section of that page a little lower down says

RECOMMENDED ZIP OPTION: > ffmpeg-win-2.2.2.zip

The zip file is http://lame3.buanzo.com.ar/ffmpeg-win-2.2.2.zip

That all seemed obscure to me. But if it’s the recommend way, I trust y’all.

BTW I edited the OP. I am trying to import a .webm file audio/webm downloaded from youtube.

Then why not simply install FFmpeg 2.2.2 per our instructions? The FFmpeg 2.2.2 we “recommend” on the Buanzo page supports WebM. The WebM container format uses the VP8 video format with Vorbis or Opus audio and FFmpeg 2.2.2 includes support for Opus as well as Vorbis audio.

If your desired WebM file does not import into Audacity using FFmpeg 2.2.2, shows us the output of Help > Show Log… and the output of MediaInfo. You can download “MediaInfo” from MediaInfo - Download MediaInfo for Microsoft Windows. Get the version without installer, because the installer may have malware or adware.
