.save('./public/_ugc/' + data + '.mp4');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 ?
