FFmpeg is a free software project that produces libraries and programs for handling multimedia data. FFmpeg includes libavcodec, an audiovideo codec library used by several other projects, libavformat Lavf,6 an audiovideo containermux and demux library, and the ffmpegcommand line program for transcoding multimedia files. FFmpeg is published under the GNU Lesser General Public License 2. GNU General Public License 2 depending on which options are enabled. 7The name of the project is inspired by the MPEG video standards group, together with FF for fast forward. 8 The logo uses a zigzag pattern that shows how MPEG video codecs handle entropy encoding. 9HistoryeditThis section needs expansion with Latest history is not reflected. You can help by adding to it. November 2. The project was started by Fabrice Bellard7 using the pseudonym Grard Lantau in 2. Michael Niedermayer from 2. Some FFmpeg developers were also part of the MPlayer project. The project publishes a new release every three months on average. Powerful MKV Converter Best way to convert MKV files support MKV to AVI, MKV to MP4, MKV to WMV, MKV to Divx. Also support other MKV to other video formats like H. H. 264 or MPEG4 Part 10, Advanced Video Coding MPEG4 AVC is a blockoriented motioncompensationbased video compression standard. As of 2014 it is one of the most. While release versions are available from the website for download, FFmpeg developers recommend that users compile the software from source using the latest build from their source code. Gitversion control system. 1. On January 1. 0, 2. Google employees announced that over 1. FFmpeg during the previous two years by means of fuzz testing. 1. Codec historyeditTwo video coding formats with corresponding codecs and one container format have been created within the FFmpeg project so far. The two video codecs are the lossless FFV1, and the lossless and lossy Snow codec. Development of Snow has stalled, while its bit stream format has not been finalized yet, making it experimental since 2. The multimedia container format called NUT is no longer being actively developed, but still maintained. 1. In summer 2. 01. 0, Fiona Glaser, Ronald Bultje, and David Conrad of the FFmpeg Team announced the ffvp. Through testing, they determined that ffvp. Googles own libvpx decoder. 1. Starting with version 0. FFmpeg also supported Web. M and VP8. 1. 6In October 2. VP91. 7 and the Open. HEVC decoder, an open source High Efficiency Video Coding HEVC decoder, were added to FFmpeg. 1. In 2. 01. 6 the native AAC encoder was considered stable, removing support for the two external AAC encoders from Visual. On and FAAC. FFmpeg 3. Einstein  retained build support for the Fraunhofer FDK AAC encoder. 1. ComponentseditCommand line toolseditffmpeg is a command line tool that converts audio or video formats. It can also capture and encode in real time from various hardware and software sources such as a TV capture card. HTTP and RTSP multimedia streaming server for live and recorded broadcasts. It can also be used to time shift live broadcasts. SDL and the FFmpeg libraries. CSV, XML, JSON, see also Mediainfo. Librarieseditlibswresample is a library containing audio resampling routines. Libav project, similar to libswresample from ffmpeg. FFmpeg audiovideo encoders and decoders. Most codecs were developed from scratch to ensure best performance and high code reusability. Lavf6 is a library containing demuxers and muxers for audiovideo container formats. FFmpeg. This library includes hash functions Adler 3. CRC, MD5, RIPEMD, SHA 1. SHA 2, Murmur. Hash. HMAC MD 5, HMAC SHA 1 and HMAC SHA 2, ciphers DES, RC4, AES, AES CTR, TEA, XTEA, Blowfish, CAST 1. Twofish and Camellia, LZO decompressor and Base. Filters have been ported from many projects including MPlayer and avisynth. Supported hardwareeditFFmpeg encompasses software implementations of video and audio compressing and decompressing algorithms. These can be compiled and run on diverse instruction sets. Many widespread instruction sets are supported by FFmpeg, including x. IA 3. 2 and x. 86 6. PPC Power. PC, ARM, DEC Alpha, SPARC, and MIPS. 2. Special purpose hardwareeditVarious application specific integrated circuit related to video and audio compression and decompression do exist. Such ASIC can perform the computation for audiovideo decompression or compression partly or fully to offload these from the host CPU. To make use of such ASIC, instead of a complete implementation of some algorithm, only the API is required. There are numerous ASICs and APIs available, of which several are supported by FFmpeg. 2. Supported codecs and formatseditImage formatseditFFmpeg supports many common and some uncommon image formats. The PGMYUV image format is a homebrewn variant of the binary P5 PGM Netpbm format. FFmpeg also supports 1. PGM and PPM formats, and the binary P7 PAM format with or without alpha channel, depth 8 bit or 1. Supported formatseditIn addition to FFV1 and Snow formats, which were created and developed from within FFmpeg, the project also supports the following formats Group. Format type. Format name.
