VLC media player is a highly portable multimedia player for various
audio and video formats (MPEG-1, MPEG-2, MPEG-4, DivX, mp3, ogg, ...)
as well as DVDs, VCDs, and various streaming protocols.
It can also be used as a server to stream in unicast or multicast
in IPv4 or IPv6 on a high-bandwidth network.

LibOFX is a parser and API designed to allow applications to support
OFX command responses, usually provided by financial institutions for
statement downloads. The author says, "To my knowledge, it is the first
working OpenSource implementations of the OFX (Open Financial eXchange)
specification on the client side. This project was first started as my
end of degree project, with the goal of adding OFX support to GnuCash.
It has since evolved into a generic library, so all OpenSource
Financial software can benefit from it."

Poppler is a fork of the xpdf PDF viewer developed by Derek Noonburg of
Glyph and Cog, LLC. There are two reasons for forking xpdf. First, to
provide PDF rendering functionality as a shared library to centralize
the maintenence effort. Today a number of applications incorporate the
xpdf code base and whenever a security issue is discovered, all these
applications exchange patches and put out new releases. In turn, all
distributions must package and release new versions of these xpdf based
viewers. Due to this, there is a lot of duplicated effort. Even if
poppler in the short term introduces yet another xpdf-derived code base
to the world, hopefully, over time these applications will adopt
poppler. After all, only one application needs to use poppler to break
even.

Second, libpoppler intends to move forward in a number of areas that do
not fit within the goals of xpdf. By design, xpdf depends on very few
libraries and runs on a wide range of X-based platforms. This is a
strong feature and reasonable design goal. However, poppler intends to
replace parts of xpdf that are now available as standard components of
modern Unix desktop environments. One such example is fontconfig,
which solves the problem of matching and locating fonts on the system
in a standardized and well understood way. Another example is cairo,
which provides high quality 2D rendering. See the file TODO for a list
of planned changes.

Wayland protocols that adds functionality not
available in the Wayland core protocol. Such protocols either adds
completely new functionality, or extends the functionality of some other
protocol either in Wayland core, or some other protocol in
wayland-protocols.
