Comment (by burek):
Btw, by "it doesn't work" I mean everything hangs, just like ffmpeg in
second shell is waiting for something, and it doesn't read both inputs in
parallel.
The first ffmpeg shows that it read the input properly and is just about
to create outputs:

The second ffmpeg just hangs after the intro text:
