libavcodec is a free software/open source LGPL-licensed library of codecs for encoding and decoding video and audio data. It is part of the FFmpeg project.
libavcodec is an integral part of many open-source multimedia applications and frameworks. The popular MPlayer, 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.
