v4l-utils is a collection of various video4linux (V4L) and DVB utilities. libv4l is an accompanying collection of libraries that adds a thin abstraction layer on top of video4linux2 (V4L2) devices. The purpose of this 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. It consists of 3 different libraries. 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 support for the application transparent libv4lconvert conversion where necessary.
v9fs provides a Plan 9 9P2000 resource sharing protocol for the Linux 2.6 kernel. This can be used to share files, devices, /proc, /sys, etc. It also works with Plan 9 file servers, and can be used to mount synthetic file systems from Plan 9 applications (see the plan9port project).
vAVRdisasm is an Atmel 8-bit AVR firmware disassembler. This single-pass disassembler can read Atmel Generic, Intel HEX8, and Motorola S-Record formatted binary files containing valid AVR firmware. vAVRdisasm is capable of a variety of formatting options, and can output directly assemble-able code.
Versatile-ISDN (vISDN for short) is yet another ISDN implementation for Linux. It aims at being an open, modular, flexible, and versatile architecture to connect Linux to the ISDN. vISDN is comprised of a channel crossconnector, a lapd/q.931 implementation, an Asterisk channel driver, PPP networking, traffic analysis through Ethereal, and much more. vISDN is in the process of obtaining a certification of compliance from an independent lab. vISDN currently supports Cologne Chip's HFC-based cards for either BRIs and PRIs in user-role or network-role.
vMovieDB is a movie collections manager for the Gnome desktop. You can play selected movies with your favorite video player, manage various types of information for your movies (title, year, media type, quality, subtitles, location, genre, and movie image), export your movies to an HTML or text document, and search for a selected movie on ImDB.com. It has a fast and light database based on XML.
vPICdisasm is a Microchip PIC firmware disassembler that supports the Baseline, Mid-Range, and Mid-Range Enhanced 8-bit PIC cores. This single-pass disassembler can read Intel HEX8 and Motorola S-Record formatted binary files containing valid PIC program binaries. vPICdisasm is capable of a variety of formatting options, including representing data constants in different bases, and can output directly assemble-able code.
vPostMaster is a complete email server for Linux. It is designed to be easily configured in all areas. It includes greylisting, whitelisting, blacklisting, and spam and virus filtering. It supports unlimited domains. It includes Webmail and POP3/IMAP as well as SMTP. Mailing lists and autoresponders are available in the commercial version. It is based on Postfix. The installation uses packages and takes only a few minutes. It features configuration through the Web of all portions of the system from a site-wide policy to per-user preferences and filters.
