PTLib is a moderately large C++ class library that originated many years
ago as a method to produce applications that run on both Microsoft
Windows and Unix X-Windows systems. It also was to have a Macintosh port
as well, but this never eventuated. In those days it was called the
PWLib the Portable Windows Library.
Since then, the availability of multi-platform GUI toolkits such as KDE
and wxWindows, and the development of the OpenH323 and OPAL projects as
primary user of the library, has emphasised the focus on networking, I/O
portability, multi-threading and protocol portability. Mostly, the
library is used to create high performance and highly portable
network-centric applications. So all the GUI abstractions ahave been
dropped and it was renamed the Portable Tools Library that you see
today.
Simple Scan is an easy-to-use application, designed to let users connect
their scanner and quickly have the image/document in an appropriate
format.
Simple Scan is basically a frontend for SANE which means that all
SANE supported scanners will work and the interface is well tested.
uShare is a UPnP (TM) A/V & DLNA Media Server. It implements the server
component that provides UPnP media devices with information on available
multimedia files. uShare uses the built-in http server of libupnp to
stream the files to clients.
GeeXboX uShare is able to provide access to both images, videos, music
or playlists files (see below for a complete file format support list
It does not act as an UPnP Media Adaptor and thus, can't transcode
streams to fit the client requirements.
Note that DLNA support is not enabled on OpenBSD.
The portable SDK for UPnP Devices (libupnp) provides developers with an
API and open source code for building control points, devices, and
bridges that are compliant with Version 1.0 of the Universal Plug and
Play Device Architecture Specification.
UPnP is an architecture that enables discovery, event notification, and
control of devices on a network, independent of operating system,
programming language, or physical network connection. UPnP is based on
common Internet standards and specifications such as TCP/IP, HTTP, and
XML.
