libv4l is a collection of libraries which adds a thin abstraction layer on top of video4linux2 devices. The purpose of this (thin) layer is to make it easy for application writers to support a wide variety of devices without having to write separate code for different devices in the same class. libv4l consists of 3 different libraries: libv4lconvert, libv4l1 and libv4l2. libv4lconvert offers functions to convert from any (known) pixel-format to V4l2_PIX_FMT_BGR24 or V4l2_PIX_FMT_YUV420. libv4l1 offers the (deprecated) v4l1 API on top of v4l2 devices, independent of the drivers for those devices supporting v4l1 compatibility (which many v4l2 drivers do not). libv4l2 offers the v4l2 API on top of v4l2 devices, while adding for the application transparent libv4lconvert conversion where necessary.

SMPEG is a free MPEG1 video player library with sound support. Video playback is based on the ubiquitous Berkeley MPEG player, mpeg_play v2.2. Audio is played through a slightly modified mpegsound library, part of Splay v0.8.2. SMPEG supports MPEG audio (MP3), MPEG-1 video, and MPEG system streams. plaympeg, gtv, and glmovie are simple video players provided to test the library. The C library interface is 'documented' in smpeg.h, and the C++ library interface is spread out over the MPEG*.h files. This is a work in progress. Only 16 bit color depth is supported. The player will dynamically conver to other color depths, but playback will be much faster if your display is already set to 16 bit color depth.

MPEG TS/PS/ES Transport, Program and Elementary Stream tools This is a set of cross-platform command line tools for working with MPEG data. The emphasis is on relatively simple tools which concentrate on MPEG (H.264 and H.262) data packaged according to H.222 (i.e., TS or PS), with a particular interest in checking for conformance. Transport Stream (TS) is typically used for distribution of cable and satellite data. Program Stream (PS) is typically used to store data on DVDs. The tools are focussed on: * Quick reporting of useful data (tsinfo, stream_type) * Giving a quick overview of the entities in the stream (esdots, psdots) * Reporting on TS packets (tsreport) or ES units/frames/ fields (esreport) * Simple manipulation of stream data (es2ts, esfilter, esreverse, esmerge, ts2es) * Streaming of data, possibly with introduced errors (tsplay)

Convey allows people across the globe to collaboratively draw images while chatting online. Using pictures in addition to words makes communicating online fun and easy. Convey is an Instant Message (IM) program. You can send an message to a friend, but unlike email, the message instantly appears on your friend's screen if they are online. Otherwise, the message is delivered to your friend when they log onto the Internet. Convey uses the Jabber protocol to send its messages. A protocol consists of the rules by which a computer communicates with another computer. Using Jabber, Convey provides users connections to other popular IM programs, such as AOL Instant Messenger, ICQ, MSN Instant Messenger, and Yahoo! Messenger.

ejabberd is a high performance Free and Open Source distributed fault-tolerant instant messaging Jabber server. Key features include: - A web administration console and command line administration tools that ensure easy set up - Support for encrypted connections to ensure secure communications - Many built-in services, including Jabber User Directory and Multi-User Chat - Standard Jabber transport compliance to enable communication with other instant messaging networks - Automatic collection of statistics for reporting and system analysis - Virtual hosting, enabling ejabberd to run several virtual domains from a single ejabberd instance - Shared rosters, so that users can have predefined entries in their contacts lists - External storage support - Large numbers of supported protocols (see the supported protocols list for details) - Multi-lingual web administration interface - Full IPv6 support

bgpq3 is a lightweight access-list/prefix-list/as-path access-list generator for Cisco and Juniper routers. This program is a mostly complete re-implementation of bgpq (net-mgmt/bgpq), with next major advantages: - much faster, especially for large as-sets. - supports ipv6 both at transport level and in prefix/access-lists generation. - supports asn32 in both asdot and asplain notation, also supports "transition" as23456 generation instead of asn32. However, bgpq3 can not be used as a full replacement of bgpq, because: - "more specific" prefix filtering is not implemented (and not planned). - GateD prefix-filters generation is not implemented (and not planned). - Cisco standard access-lists generation is not implemented (and not planned). - formatted output is not supported (yet?).

Cisco::Reconfig makes it easier to write programs to generate changes to Cisco configuration files. Cisco::Reconfig is a module that parses Cisco router configuration files. It doesn't have any real understanding of Cisco configurations so it might be useful for other similar configuration languages. It knows that nesting is shown by indentation. It knows that ! means a comment. It knows that no may proceed a line without changing where that line exists in the hierarchy. It doesn't know much else. Cisco::Reconfig can be used to modify configurations. The set() method will check the current configruation and return commands to change it if it is other than what is wanted (as passed to the set() method).

RRDBot is an SNMP polling daemon which writes the polled values to an RRD database. It can poll many different SNMP sources in an efficient manner. It has no large external dependencies, and its configuration is stored in text files. It has full support for MIB definition files and using textual MIBs instead of numerical OIDs. A nice feature is the querying of SNMP tables without using a specific index. Indexes of the rows in an SNMP table may change from time to time, and are less than ideal for long term tracking of a given value. For example RRDBot can query the traffic on your router based on the 'xl0' interface name. RRDBot also contains tools to simplify the creation of RRD files, and the various archives contained in them.
