# DESCRIPTION
**notcurses-demo** demonstrates the capabilities of the notcurses library. It
can be run in any terminal emulator or console with a correct terminfo(5)
2020-01-12 15:15:56 +00:00
database, but is at is best in a "DirectColor" 24bpp RGB environment. If
**notcurses-demo** seems to generate garbage, something is likely configured in
a way that is going to prevent notcurses from working.

The Debian version of notcurses leaves out certain multimedia considered
2020-02-05 14:39:35 +00:00
non-free under the Debian Free Software Guidelines. As a result, the
**chunli**, **eagle** , **fallin'** , **jungle** , **luigi** , and **view** demos
are unavailable through the Debian package.
2020-02-05 03:49:46 +00:00
2020-02-05 15:41:13 +00:00
If notcurses is built without FFmpeg, the **chunli** , **eagle** , **fallin'** ,
**outro**, **view** , and **xray** demos will be unavailable.
