Help With Importing mp4

Post by A Cookie » Wed Dec 27, 2017 2:40 pm

So I need to edit the audio in an mp4 file and at first I didn't have the ffmpeg files needed for more advanced files that audacity needed, so I went on youtube to figure out how to do it followed multiple videos step by step through installing. Even after the ffmpeg library autodetects the dll files it needs I still get the "mp4 is an advanced audio coding file audacity can not open" error. I've reinstalled audacity and even reinstalled the needed libraries needed but I still get this error.

We at Aydacity don't make "how-to" videos (they get out of date too quickly) - and most you find on the internet can be wildly inaccurate.

Instead follow the instruction from this page in the Audacity Manual: ... ml#winlame

Download BOTH the LAME and FFmpeg libraries.
Extract the files.
I manually put mine into this folder:
C:\Program Files (x86)\Audacity\Plug-Ins

Start Audacity..

Edit -> Preferences -> Libraries -> LOCATE

For BOTH MP3 and FFmpeg click Locate -> Browse -> (the needed file shows up in the box but that is deceiving) -> Pick Browse and manually browse to the folder where you put the plugins (.dll files).

I moved all mine to:

C:\Program Files (x86)\Audacity\Plug-Ins

Do this for BOTH. Restart Audacity and it should work just fine.

I just went through this and now mine is working perfectly.

Instructions for installing FFmpeg are provided in the Audacity manual.
Windows: ... html#winff
Mac: ... html#macff
Linux: ... html#linff

While other instructions "may" work (or may not), it is always highly recommended to follow the proper instructions as given in the official manual.
