Installed FFMPEG, still cannot import mp4 multi track audio

Post by Kbalz » Thu Jan 11, 2018 2:46 am

Hello,

Audacity 2.2.1 on Windows 64 bit
Installed the FFMPEG for Audacity per the wiki instructions
Audacity Edit -> Preferences shows that the LAME and FFMPEG Libraries were located
When I attempt to import my mp4 that has 4 audio tracks, I receive an error:

"(filename).mp4" is an Advanced Audio Coding file. Audacity cannot open this type of file. You need to convert it to a supported audio format, such as WAV or AIFF.

This is a video I recorded using Open Broadcast Software, multi tracks to mp4, pretty standard stuff and I've seen other people on YouTube import this type of file into Audacity with no problems.

here is my error log, thanks for any help in advance, -Kurt

Hello,

SOLVED

User error. Much like I did not read the directions for the forum and waiting for approval, I did not read the Audacity prompt that is showing the 4 tracks on my mp4

I actually have to pick one of the four tracks to import. I was not clicking on any track, and simply clicking OK, expecting that Audacity would then import all 4 tracks into one project. I must do them one at a time and that is perfectly fine.

I can't be sure about that specific format, but with at least some multi-channel formats, you can select multiple channels to import at the same time. Give that a go and see if it works with that format.

This works. During mp4 import, Audacity prompts for which track to import. You can use shift or alt to select multiple tracks from that list and they open in a single Audacity project. Thank you Steve!
