Hi!
I am trying to concatenate two .mp3 files using ffmpeg lambda-layer. I have
what I think is the correct command, but I struggle to represent it in code
so that it is formatted correctly for the lambda layer. Here is a piece of
code that I am struggling to get right:
spawnSync(
'/opt/ffmpeg/ffmpeg',
[
'-i',
'"concat:/tmp/pt1.mp3|/tmp/pt2.mp3"',
'-acodec',
'copy',
`/tmp/${fileName}`
],
{ stdio: 'inherit' }
)
The error I'm getting: "concat:/tmp/pt1.mp3|/tmp/pt2.mp3": No such file or
directory.
I tried to list files in /tmp/ folder - both files listed in the input are
there, not sure why lambda layer can't find them.
Similar question:

Ffmpeg concatenate protocol documentation:

Thanks in advance!
