Guvcview
Guvcview (GTK+ UVC Viewer) is a webcam application, i.e. software to handle UVC streams, for the Linux desktop, started by Paulo Assis in 2008. The application is written in C and is free and open-source software released under GPL-2.0-or-later. Guvcview is compatible with all V4L2 camera devices, using the Linux UVC driver and based on ''luvcview'' for video rendering. Audio support employs the PortAudio open-source library. The application's user interface is built using GTK+ and is designed to be simple and easy to use. The application has been noted as using fewer resources than other webcam applications, such as the GNOME standard webcam application, Cheese, and is an alternative to other webcam applications, including Apple Photo Booth and KDE Kamoso. Features Guvcview uses a two-window interface in normal use. One window displays the camera image to be recorded and the other displays the settings and controls, as well as menus. Through the Linux UVC driver, Guvc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lubuntu
Lubuntu ( ) is a lightweight Linux distribution based on Ubuntu that uses the LXQt desktop environment in place of GNOME. Lubuntu was originally touted as being "lighter, less resource hungry and more energy-efficient", but now aims to be "a functional yet modular distribution focused on getting out of the way and letting users use their computer". Lubuntu originally used the LXDE desktop, but moved to the LXQt desktop with the release of Lubuntu 18.10 in October 2018, due to the slow development of LXDE, losing support for GTK 2 as well as the more active and stable LXQt development without GNOME dependencies. The name ''Lubuntu'' is a portmanteau of ''LXQt'' and ''Ubuntu''. The LXQt name derives from the merger of the LXDE and Razor-qt projects, while the word ''Ubuntu (philosophy), Ubuntu'' means "humanity towards others" in the Zulu language, Zulu and Xhosa language, Xhosa languages. Lubuntu received official recognition as a formal member of the Ubuntu family on 11 May 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Webcam
A webcam is a video camera which is designed to record or stream to a computer or computer network. They are primarily used in Videotelephony, video telephony, live streaming and social media, and Closed-circuit television, security. Webcams can be Built-in function, built-in computer hardware or Peripheral, peripheral devices, and are commonly connected to a device using USB or Internet protocol suite, wireless protocol. Webcams have been used on the Internet as early as 1993, and the first widespread commercial one became available in 1994. Early webcam usage on the Internet was primarily limited to stationary shots streamed to web sites. In the late 1990s and early 2000s, instant messaging clients added support for webcams, increasing their popularity in video conferencing. Computer manufacturers later started integrating webcams into laptop hardware. In 2020, the COVID-19 pandemic caused a shortage of webcams due to the increased number of people Remote work, working from hom ...

Video4Linux
Video4Linux (V4L for short) is a collection of device drivers and an API for supporting realtime video capture on Linux systems. It supports USB webcams, TV tuners, CSI cameras, and related devices, standardizing their output, so programmers can easily add video support to their applications. Video4Linux is responsible for creating V4L2 device nodes aka a device file (/dev/videoX, /dev/vbiX and /dev/radioX) and tracking data from these nodes. The device node creation is handled by V4L device drivers using the video_device struct (v4l2-dev.h) and it can either be allocated dynamically or embedded in another larger struct. Video4Linux was named after Video for Windows (which is sometimes abbreviated "V4W"), but is not technically related to it. While Video4Linux is only available on Linux, there is a compatibility layer available for FreeBSD called Video4BSD. This provides a way for many programs that depend on V4L to also compile and run on the FreeBSD operating system. Histor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Instruction Set
In computer science, an instruction set architecture (ISA) is an abstract model that generally defines how software controls the CPU in a computer or a family of computers. A device or program that executes instructions described by that ISA, such as a central processing unit (CPU), is called an ''implementation'' of that ISA. In general, an ISA defines the supported Machine code, instructions, data types, Register (computer), registers, the hardware support for managing Computer memory, main memory, fundamental features (such as the memory consistency, addressing modes, virtual memory), and the input/output model of implementations of the ISA. An ISA specifies the behavior of machine code running on implementations of that ISA in a fashion that does not depend on the characteristics of that implementation, providing binary compatibility between implementations. This enables multiple implementations of an ISA that differ in characteristics such as Computer performance, performa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...

Ubuntu Version History
Ubuntu releases are made semiannually by Canonical (company), Canonical Ltd using the year and month of the release as a Software versioning, version number. The first Ubuntu release, for example, was #0410, Ubuntu 4.10 and was released on 20 October 2004. Consequently, version numbers for future versions are provisional; if the release is delayed until a different month (or even year) than planned, the version number will change accordingly. Canonical schedules Ubuntu releases to occur approximately one month after GNOME releases, resulting in each Ubuntu release including a newer version of GNOME. Every fourth release, occurring in the second quarter of even-numbered years, has been designated as a long-term support (LTS) release. The desktop version of LTS releases for #1004, 10.04 and earlier were supported for three years, with server version support for five years. LTS releases #1204, 12.04 and newer are freely supported for five years. Through the Expanded Security Mainte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
