libavcodec is a codec collection and part of the free FFmpeg project. In contrast to many other collections, libavcodec does not combine existing individual codecs, but contains mostly completely new codecs in order to achieve better performance and openness of source. In addition, all codecs have been combined in a single program library that can be integrated directly into the respective program. It is also possible to integrate libavcodec as a shared object (Linux: .so) or dynamic link library (Windows: .dll) in applications. The libavcodec library currently supports more than 50 video formats, including H.264 (MPEG-4 AVC), MPEG -1/2, MPEG-4 ASP (DivX / Xvid), WMV 7/8/9, VP8 , Cinepak and HuffYUV , as well as more than 30 audio formats ( MP3 , Vorbis , AC3 , AAC , WMA 1/2 and others) read (decode) and write (encode) many of them. In addition, it offers good portability and is therefore available on all major operating systems.

By using the libavcodec (directly or integrated in a program) you save the installation and registration of each individual codec and possible conflicts between them. The regular codecs can also be installed so that you have an alternative if you have problems.

The library is used by a large number of programs, in particular media players (for example VLC media player ). The widely used DirectShow filter and VfW codec ffdshow also uses libavcodec (among other codecs) . In this way, DirectShow-based multimedia players such as Windows Media Player or alternatives such as Media Player Classic can also use the library.
