V4L2
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] |
Linux
Linux ( ) is a family of open source Unix-like operating systems based on the Linux kernel, an kernel (operating system), operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically package manager, packaged as a Linux distribution (distro), which includes the kernel and supporting system software and library (computing), libraries—most of which are provided by third parties—to create a complete operating system, designed as a clone of Unix and released under the copyleft GPL license. List of Linux distributions, Thousands of Linux distributions exist, many based directly or indirectly on other distributions; popular Linux distributions include Debian, Fedora Linux, Linux Mint, Arch Linux, and Ubuntu, while commercial distributions include Red Hat Enterprise Linux, SUSE Linux Enterprise, and ChromeOS. Linux distributions are frequently used in server platforms. Many Linux distributions use the word "Linux" in their name, but the Free ...

Libav
FFmpeg is a free and open-source software project consisting of a suite of libraries and programs for handling video, audio, and other multimedia files and streams. At its core is the command-line ffmpeg tool itself, designed for processing video and audio files. It is widely used for format transcoding, basic editing (trimming and concatenation), video scaling, video post-production effects, and standards compliance (SMPTE, ITU). FFmpeg also includes other tools: ffplay, a simple media player, and ffprobe, a command-line tool to display media information. Among included libraries are libavcodec, an audio/video codec library used by many commercial and free software products, libavformat (Lavf), an audio/video container mux and demux library, and libavfilter, a library for enhancing and editing filters through a GStreamer-like filtergraph. FFmpeg is part of the workflow of many other software projects, and its libraries are a core part of software media players such as VLC, an ...

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] |

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 ...

Mpv (media Player)
mpv is free and open-source media player software based on MPlayer, mplayer2 and FFmpeg. It runs on several operating systems, including Unix-like operating systems (Linux, BSD-based, macOS) and Microsoft Windows, along with having an Android port called mpv-android. It is cross-platform, running on ARM, MIPS, PowerPC, RISC-V, s390x, x86/IA-32, x86-64, and some other by 3rd party. History mpv was forked by Vincent Lang, also known as wm4, in 2012 from mplayer2, which was forked in 2010 from MPlayer. The motive for the fork was to encourage developer activity by removing unmaintainable code and dropping support for very old systems. As a result, the project had a large influx of contributions. Since June 2015, the project's source code is being relicensed from GNU General Public License version 2 or later (GPLv2+) to GNU Lesser General Public License version 2.1 or later (LGPLv2.1+) to allow using mpv as a library in more applications. Changes from MPlayer mpv has ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MPlayer
MPlayer is a free and open-source media player software application. It is available for Linux, OS X and Microsoft Windows. Versions for OS/2, Syllable Desktop, Syllable, AmigaOS, MorphOS and AROS Research Operating System are also available. A port for DOS using DJGPP is also available. Versions for the Wii Homebrew Channel and Amazon Kindle have also been developed. History Development of MPlayer began in 2000. The original author, Hungary, Hungarian Árpád Gereöffy, started the project because he was unable to find any satisfactory video players for Linux after XAnim stopped development in 1999. The first version was titled ''mpg12play v0.1'' and was hacked together in half an hour using ''libmpeg3'' from Cinelerra, Cinelerra-HV. After ''mpg12play v0.95pre5'', the code was merged with an Audio Video Interleave, AVI player based on ''avifile''s ''Win32 Dynamic-link library, DLL loader'' to form MPlayer v0.3 in November 2000. Gereöffy was soon joined by many other programme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
