  I have the above code that can successfully generate a 5s video in my local Mac.

  However, when I push the code to the production Ubuntu, it can only generate a 1s video only.

  There is no error in the Ubuntu side. I wonder if I missed anything.

  I also wonder should I preload the source images first ?

  node v12.13.0

  ffmpeg version 2.8.15-0

  ubuntu0.16.04.1
