He meant one script per thread.
Each asynchronous function started, starts in separate thread.
So in that example you will have 2 threads since 2 asynchronous functions
will be started, each with its own (different) script.
I am experiencing confusion when looping/foreach through .MP4 files in the Input File Folder.
When running just 1 thread, it works normally and runs smoothly. However, when I use 2 threads simultaneously, it always reads the same file in each thread. Is there anyone who can help me? Thank you.
