error: Error: Error exporting file

[dunstan]

I have a question about an error, and two small additional questions:

1. I tried running this for the first time and got the error shown below. Could anyone explain it to me, please? I have FFmpeg installed.
2. I specified a 2 second silence gap, but it says "Silence gap added duration=3". Why the extra second?
3. Is there a way to add silence to the start of the track, too?

Thanks very much.

I have to admit that the error isn't really descriptive. I won't be able to fix that today but I will take a look into this later tomorrow.

Getting the same issue. Without audiosprite, ffmpeg converts files just fine.
OS: macOS 10.13.6
ffmpeg version 4.0.2
Tried node 10.7.0, 8.11.3 LTS - same results.
Also tried different input file formats - no diff.

Also, I'm pretty sure it was working just fine in WSL environment (read: Ubuntu) on windows a week ago.

Ping!

[SargoDarya]

Sorry, haven't had the time yet to look into it. Can you maybe prepare a zip file containing your setup so I have an exact thing to test this easier?

[etall]

the same error

/usr/local/lib/node_modules/audiosprite/audiosprite.js:312:27

mac 10.13.5
ffmpeg version 4.0.1
node v10.8.0

[SargoDarya]

@etall @metalim Can you guys provide a sample zip with the setup you used so I can investigate that further?

[maksmaers]

@SargoDarya I had the same issue, after debugging I found result for ffmpeg command
ffmpeg -y -ar 44100 -ac 1 -f s16le -i /tmp/audiosprite.9684745136330044 -acodec libvorbis -f ogg -ab 128k output.ogg
and I got console error
/tmp/audiosprite.9684745136330044: No such file or directory
if I create this file it is ok

  })

If you're on Mac, you have to install the dependencies exactly as the documentation states:

brew install ffmpeg --with-theora --with-libvorbis

I had installed ffmpeg previously with Homebrew, but not with the options above. Re-installed as above and it works fine now.

[SargoDarya]

Even if that works we probably should add better error reporting. Error exporting file just doesn't cut it.

[mnovbaalen]

I had the same error: Error exporting file.
Running the ffmpeg command manually was working without problems.

It seems to be that audiosprite does not work with ffmpeg 4.x:

At first I installed ffmpeg with snap on Ubuntu 18 LTS. (This is ffmpeg version 4.x.)
When de-installing this version of ffmpeg and installing ffmpeg with the command

sudo apt install ffmpeg

ffmpeg 3.x is installed, and the problem is solved!

This worked for me

[ruthgrace]

on mac osx. upgraded from ffmpeg version 3.4.2 to 4.4 using brew, and was able to get over this error. maybe audiosprite has been updated to only work with ffmpeg 4 now?

[RedRoosterMobile]

I circumvented the bug by using -e mp3 option..
