Free and open-source software portal; libavcodec is a free and open-source [4] library of codecs for encoding and decoding video and audio data. [5]libavcodec is an integral part of many open-source multimedia applications and frameworks.
This is a listing of open-source codecs—that is, open-source software implementations of audio or video coding formats, audio codecs and video codecs respectively. Many of the codecs listed implement media formats that are restricted by patents and are hence not open formats.

Linear pulse-code modulation (LPCM, generally only described as PCM) is the format for uncompressed audio in media files and it is also the standard for CD-DA; note that in computers, LPCM is usually stored in container formats such as WAV, AIFF, or AU, or as raw audio format, although not technically necessary.
libvpx offers an asymmetric codec – with encoding taking much longer than decoding – and options for configuring encoding expense independently from decoding complexity. A lookahead of up to 25 frames can be configured, which improves compression efficiency but introduces latency and thereby hurts real-time performance.
Avidemux was written from scratch, but additional code from FFmpeg, MPlayer, Transcode and Avisynth has been used on occasion as well. Nonetheless, it is a completely standalone program that does not require any other programs to read, decode, or encode other than itself.
Here is a list of applications known to be able to read and/or write FFV1 video files, either natively or by installing codec packages. Entries marked with "-" means that they generally only support either encoding or decoding. The term "built-in" means that the application can handle FFV1 without the necessity to install additional codec packages.
