Ffdshow-tryouts
ffdshow is an open-source unmaintained codec library that is mainly used for decoding of video in the MPEG-4 ASP (e.g. encoded with DivX or Xvid) and H.264/MPEG-4 AVC video formats, but it supports numerous other video and audio formats as well. It is free software released under GNU General Public License 2.0, runs on Windows, and is implemented as a Video for Windows (VFW) codec and a DirectShow filter. Installation and configuration ffdshow does not include a media player or container parsers. Instead, after installation of ffdshow, compatible DirectShow or VFW media players such as Media Player Classic, Winamp, and Windows Media Player will use the ffdshow decoder automatically, thus avoiding the need to install separate codecs for the various formats supported by ffdshow. The user configures ffdshow's audio and video settings by launching the ffdshow video decoder configuration program independently of any media player. For playing transport stream files such as AV ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows 7
Windows 7 is a major release of the Windows NT operating system developed by Microsoft. It was released to manufacturing on July 22, 2009, and became generally available on October 22, 2009. It is the successor to Windows Vista, released nearly three years earlier. It remained an operating system for use on personal computers, including home and business desktops, laptops, tablet PCs and media center PCs, and itself was replaced in November 2012 by Windows 8, the name spanning more than three years of the product. Until April 9, 2013, Windows 7 original release included updates and technical support, after which installation of Service Pack 1 was required for users to receive support and updates. Windows 7's server counterpart, Windows Server 2008 R2, was released at the same time. The last supported version of Windows based on this operating system was released on July 1, 2011, entitled Windows Embedded POSReady 7. Extended support ended on January 14, 2020, over ten years af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demultiplexer (media File)
A demultiplexer for digital media files, or media demultiplexer, also called a file splitter by laymen or consumer software providers, is software that demultiplexes individual elementary streams of a media file, ''e.g.'', audio, video, or subtitles and sends them to their respective decoders for actual decoding. Media demultiplexers are not decoders themselves, but are format container handlers that separate media streams from a (container) file and supply them to their respective audio, video, or subtitles decoders. Notable file splitters * Microsoft AVI splitter - Part of Microsoft Windows. * Haali Media Splitter - demultiplexes MP4 ( MPEG-4), M2TS ( MPEG transport stream) and MKV (Matroska) files. * FLV Splitter - demultiplexes Flash video files. * Gabest splitter (part of Media Player Classic) - demultiplexes e.g. 3GP, MP4 * LAV Splitter - part of the LAV Filters project (open source DirectShow media splitter and decoders). * libavformat (part of the FFmpeg project) - ...

MPEG-4 Part 2
MPEG-4 Part 2, MPEG-4 Visual (formally ISO/ IEC 14496-2) is a video compression format developed by the Moving Picture Experts Group (MPEG). It belongs to the MPEG-4 ISO/IEC standards. It uses block-wise motion compensation and a discrete cosine transform (DCT), similar to previous standards such as MPEG-1 Part 2 and H.262/MPEG-2 Part 2. Several popular codecs including DivX, Xvid, and Nero Digital implement this standard. Note that MPEG-4 Part 10 defines a different format from MPEG-4 Part 2 and should not be confused with it. MPEG-4 Part 10 is commonly referred to as H.264 or AVC, and was jointly developed by ITU-T and MPEG. MPEG-4 Part 2 is H.263 compatible in the sense that a basic H.263 bitstream is correctly decoded by an MPEG-4 Video decoder. (MPEG-4 Video decoder is natively capable of decoding a basic form of H.263.) In MPEG-4 Visual, there are two types of video object layers: the video object layer that provides full MPEG-4 functionality, and a reduced functionali ...

Libavcodec
libavcodec is a free and open-source library of codecs for encoding and decoding video and audio data. libavcodec is an integral part of many open-source multimedia applications and frameworks. The popular MPV, xine and VLC media players use it as their main, built-in decoding engine that enables playback of many audio and video formats on all supported platforms. It is also used by the ffdshow tryouts decoder as its primary decoding library. libavcodec is also used in video editing and transcoding applications like Avidemux, MEncoder or Kdenlive for both decoding and encoding. libavcodec contains decoder and sometimes encoder implementations of several proprietary formats, including ones for which no public specification has been released. As such, a significant reverse engineering effort is part of libavcodec development. Having such codecs available within the standard libavcodec framework gives a number of benefits over using the original codecs, most notably increased ...

AviSynth
AviSynth is a frameserver program for Microsoft Windows, Linux and macOS initially developed by Ben Rudiak-Gould, Edwin van Eggelen, Klaus Post, Richard Berg and Ian Brabham in May 2000 and later picked up and maintained by the open source community which is still active nowadays. It is free software under GNU GPL license. Scripting video editor AviSynth acts as a non-linear video editor controlled entirely by scripting (without a GUI). It emulates an AVI video file (or WAV audio file) as seen by the VFW downstream application, which is typically a media player, video editing software, or an encoder. AviSynth is built upon ''filters'', which are much like DirectShow filters, but with a different binary interface. Filter capabilities include cropping, deinterlacing, inverse telecine, working with still images, doing basic color grading, reducing video noise, and many other things. AviSynth also performs traditional video editing tasks like cutting, trimming and re-sequenc ... [...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, 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, 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 a half-hour using ''libmpeg3'' from . After ''mpg12play v0.95pre5'', the code was merged with an AVI player based on ''avifile''s ''Win32 DLL loader'' to form MPlayer v0.3 in November 2000. Gereöffy was soon joined by many other programmers, in the beginning mostly from Hungary, but later worldwide. Alex Beregszászi has maintai ...

Dolby Laboratories
Dolby Laboratories, Inc. (often shortened to Dolby Labs and known simply as Dolby) is an American company specializing in audio noise reduction, audio encoding/compression, spatial audio, and HDR imaging. Dolby licenses its technologies to consumer electronics manufacturers. History Dolby Labs was founded by Ray Dolby (1933–2013) in London, England, in 1965. In the same year, he invented the Dolby Noise Reduction system, a form of audio signal processing for reducing the background hissing sound on audio tape recordings. His first U.S. patent on the technology was filed in 1969, four years later. The method was first used by Decca Records in the UK. He moved the company headquarters to the United States (San Francisco, California) in 1976. The first product Dolby Labs produced was the Dolby 301 unit which incorporated Type A Dolby Noise Reduction, a compander-based noise reduction system. These units were intended for use in professional recording studios. Dolby was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Filter (video)
A video filter is a software component that performs some operation on a multimedia stream. Multiple filters can be used in a chain, known as a ''filter graph'', in which each filter receives input from its upstream filter, processes the input and outputs the processed video to its downstream filter. __TOC__ With regards to video encoding three categories of filters can be distinguished: * prefilters: used before encoding * intrafilters: used while encoding (and are thus an integral part of a video codec) * postfilters: used after decoding Prefilters Common ''prefilters'' include: * denoising * resizing ( upsampling, downsampling) * contrast enhancement * deinterlacing (used to convert interlaced video to progressive video) * deflicking In video processing, deflicking is a filtering operation applied to brightness Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light. In other words, brightness is the perce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Image Resolution
Image resolution is the detail an image holds. The term applies to digital images, film images, and other types of images. "Higher resolution" means more image detail. Image resolution can be measured in various ways. Resolution quantifies how close lines can be to each other and still be visibly ''resolved''. Resolution units can be tied to physical sizes (e.g. lines per mm, lines per inch), to the overall size of a picture (lines per picture height, also known simply as lines, TV lines, or TVL), or to angular subtense. Instead of single lines, line pairs are often used, composed of a dark line and an adjacent light line; for example, a resolution of 10 lines per millimeter means 5 dark lines alternating with 5 light lines, or 5 line pairs per millimeter (5 LP/mm). Photographic lens and film resolution are most often quoted in line pairs per millimeter. Types The resolution of digital cameras can be described in many different ways. Pixel count The term ''resolution'' is o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LAV Filters
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 of 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, and ...

MPEG Transport Stream
MPEG transport stream (MPEG-TS, MTS) or simply transport stream (TS) is a standard digital container format for transmission and storage of audio, video, and Program and System Information Protocol (PSIP) data. It is used in broadcast systems such as DVB, ATSC and IPTV. Transport stream specifies a container format encapsulating packetized elementary streams, with error correction and synchronization pattern features for maintaining transmission integrity when the communication channel carrying the stream is degraded. Transport streams differ from the similarly-named MPEG program stream in several important ways: program streams are designed for reasonably reliable media, such as discs (like DVDs), while transport streams are designed for less reliable transmission, namely terrestrial or satellite broadcast. Further, a transport stream may carry multiple programs. Transport stream is specified in '' MPEG-2 Part 1, Systems'', formally known as '' ISO/IEC standard ...
