Editing FFmpeg (section)

== Components ==

=== Command-line tools ===
* ''ffmpeg'' 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<ref>[[:commons:File:Gentoo-portage-installing-and-using-of-equery.webm|This video of Linux desktop (X11) was captured by ffmpeg and encoded in realtime]]{{Circular reference|date=March 2024}}</ref> such as a TV capture card.
* ''ffplay'' is a simple media player utilizing [[Simple DirectMedia Layer|SDL]] and the FFmpeg libraries.
* ''ffprobe'' is a command-line tool to display media information (text, [[Comma-separated values|CSV]], [[XML]], [[JSON]]), see also [[MediaInfo]].

=== Libraries ===
* ''libswresample'' is a library containing audio [[Resampling (audio)|resampling]] routines.
* ''libavresample'' is a library containing audio resampling routines from the Libav project, similar to ''libswresample'' from ''ffmpeg''.
* ''[[libavcodec]]'' is a library containing all of the native FFmpeg audio/video encoders and decoders. Most codecs were developed from scratch to ensure best performance and high code reusability.
* ''libavformat'' (Lavf)<ref name="Lavf" /> is a library containing demuxers and muxers for audio/video container formats.
* ''libavutil'' is a helper library containing routines common to different parts of FFmpeg. This library includes hash functions, ciphers, [[Lempel–Ziv–Oberhumer|LZO]] decompressor and [[Base64]] encoder/decoder.
* ''libpostproc'' is a library containing older [[H.263]] based [[video postprocessing]] routines.
* ''libswscale'' is a library containing video [[image scaling]] and [[Color space|colorspace]]/pixelformat conversion routines.
* ''libavfilter'' is the substitute for vhook which allows the video/audio to be modified or examined (for debugging) between the decoder and the encoder. Filters have been ported from many projects including [[MPlayer]] and [[avisynth]].
* ''libavdevice'' is a library containing audio/video io through internal and external devices.
