Answer 1

Windows is not supported as it doesn't have pseudo-terminal, select() and other unix capabilities. Installing Cygwin won't help either as it doesn't support UNIX-like pseudo-terminal as well.

^{Source: Windows not supported at GH-47 & GH-150}

Workarounds

• You may try mattn/asciinema fork (windows branch).
• Run it within a Docker container.
• Install asciinema in Bash terminal in Ubuntu for Windows

Answer 2

In the Windows world, termios is available via Cygwin because of the POSIX specification.

Mingw32 does not support termios.

(I've a similar issue with urwid, which depends on termios, too)
