Recommended Open Source Portability Framework
If you're looking for the base portability/framework library for building
your application, then I can recommend the following fine libraries:
| APR |
Apache Portable Runtime, a fine C library/framework for building
portable and high performance applications. |
| ACE |
Adaptive Communication Environment, a fine C++ library/framework
featuring many design patterns for building portable and high performance
applications. |
| PJLIB |
PJLIB contains many functionalities as found in APR and ACE. It is written in C
and it takes portability to extreme level.
|
Recommended Open Source Media Components
If you're looking for some components/libraries for your multimedia
applications, then I can recommend the following fine software libraries:
| PortAudio |
a fine portable cross-platform Audio API written in C for
abstracting sound devices on Windows, Windows Mobile/WinCE, Unix, Linux, MacOS,
etc. |
| resample |
a fine library for performing high level sample rate conversion. |
| Speex |
a fine audio codec! (what else can I say) |
| PJMEDIA |
a media framework suitable for embedeed/DSP or desktop development
alike. |
Open Source SIP (Session Initiation Protocol) Stacks
Please find below links to opensource SIP stacks are actively
maintained at the time of writing:
| NIST
SIP |
Java SIP stack as reference implementation of JAIN API, so
it's has good API and documentation. It also has reference
implementation for servers and user agent. |
| minisip |
GUI user agent and SIP stack with focus on security, and is portable across
Win32, Windows Mobile, Linux, and Linux iPaq. Supports audio and video. [LGPL].
|
| mjsip |
SIP stack written in Java, with layered API approach. Applications
include servers and user agent with audio and video capabilities. [GPL] |
| opensipstack |
SIP stack with media, written in C++ and depends on PWLIB. The website has
reference implementation for SBC and also an ActiveX component for building SIP
user agents.
Footprint is quite large (megs?), but it has media stack implementation (with
video?) too. [MPL]
|
| osip2 and exosip2 |
One of the earliest open source SIP stack, so it enjoys good number of adopters.
Footprint is quite small (several hundreds KBs), and supported ports include
Windows, Linux/*nix, VxWorks, MacOS X, and many embedded
targets. Media stack is available via commercial license only. [GPL or
commercial].
|
| PhAPI |
PhoneAPI from OpenWengo project, written
in C. It says to provide easy to use high level API for developing SIP audio
and video user agents.
Ports include Linux, Windows, and MacOS X. Media stack included. (GPL)
|
| PJSIP |
The SIP (and media) stack features in this website.
PJSIP SIP stack is written in C and is mainly targetted for small footprint, feature rich user
agents, although it has attracted some server side developments too.
Footprint is very small (<200KB), performance is very good (thousands of calls per second), and it is very very portable (Windows,
Windows Mobile (WinCE, PDA, SmartPhone), Linux, *nix, MacOS X, *BSD (FreeBSD), RTEMS, Symbian OS, etc.),
which makes it good candidate for embedded developments.
Complete media framework is available with PJMEDIA. [GPL or other]
|
| resiprocate |
C++ stack from SIPFoundry non-profit SIP
community project. The community is backed by many commercial companies and it
hosts health number of active developers. (Vocal)
|
| Sofia SIP |
A SIP library written in C for building SIP clients. Supports many SIP call,
presence, instant messaging features, as well as TCP, IPv6, TLS, and STUN
support.
Footprint is quite small (several hundreds KBs), and there is user agent
reference implementation which uses gstreamer for the media. (LGPL)
