Cannot import mp4 file

Audacity Help Forum Windows

I cant open mp4 files in audacity like the title says. I have ffmpeg installed on my machine but im still getting the error message when opening an mp4 file. I already looked in the forum but i wasnt able to find any information

My audacity is on version 3.2.1, i have the 64bit Version and ffmpeg is also the 64bit Version. (Installed it from this url)

This is the log after startup

16:37:02: Audacity 3.2.1
16:37:02: sqlite3 message: (1) no such table: project in "SELECT 1 FROM project LIMIT 1;"
16:37:03: Error: Failed to load shared library 'avformat-59.dll' (error 126: Das angegebene Modul wurde nicht gefunden.)

And the log after trying to open an mp4 file

So this means FFmpeg was loaded OK. The other “errors” are really just “red herrings”, and should probably be reworded. (I get the same “errors” on my machine, yet it loads mp4 files OK).

If you have any custom “rules” set in Edit > Preferences > Import/Export > Extended Import, you can try deleting those custom rules.

You can try converting the file to .WAV using a third party tool such as VLC.

If you want to post the problem file on a public file sharing service, someone will take a look at it and see if they can duplicate your issue.
