![]() Decoders in the libavcodec (H.264, SVQ3, WMV3, VP3, Theora, Indeo, Dirac, Lagarith and others). FFmpeg codecs – Codecs in the libavcodec library from the FFmpeg project ( FFV1, Snow, MPEG-1, MPEG-2, MPEG-4 part 2, MSMPEG-4, WMV2, SVQ1, MJPEG, HuffYUV and others).The reference implementation is released under the LGPL 2.1 and currently available in version 2.0 (as of 12/2020) xvc - An open source video codec, aiming to compete with h.265 and AV1. ![]() Google libgav1 - An AV1 decoder by Google.Xiph.Org rav1e - An AV1 encoder written in Rust.VideoLAN dav1d - An AV1 decoder for decoding videos with AV1 codec.While SVT-AV1 already performs very well in constrained quality mode and is economically usable for many scenarios, as of the time being commercial implementations like Aurora1 may still beat it. SVT-AV1 is generally considered to be the most optimized and fastest free AV1 encoder, which is why it serves as the base for the development of new, free, general-purpose and production-ready implementations in the AOMedia Software Implementation Working Group. SVT-AV1 - An AV1 encoder originally developed by Intel and Netflix, which is available as FLOSS now.libvpx – VP8 and VP9 implementation formerly a proprietary codec developed by On2 Technologies, released by Google under a BSD-like license in May 2010.Xvid – MPEG-4 Part 2 codec, compatible with DivX.x265 – An encoder based on the High Efficiency Video Coding (HEVC/H.265) standard.OpenVVC an VVC /H.266 Real Time- Decoder for Mac OS, Windows, Linux and Android and special Version of FFmpeg, which was used for Ateme Satellite Broadcast Test.OpenH264 – H.264 baseline profile encoding and decoding.x264 is not a codec (en coder/ decoder) it is just an encoder (it cannot decode video). x264 – H.264/MPEG-4 AVC implementation.For example, x264 is a widely used open source implementation of the heavily patent encumbered MPEG-4 AVC video compression standard. Many of the codecs listed implement media formats that are restricted by patents and are hence not open formats. This is a listing of open-source codecs-that is, open-source software implementations of audio or video coding formats. ( August 2022) ( Learn how and when to remove this template message) Several templates and tools are available to assist in formatting, such as Reflinks ( documentation), reFill ( documentation) and Citation bot ( documentation). Please consider converting them to full citations to ensure the article remains verifiable and maintains a consistent citation style. The most recent versions of the codec objects also enable access to some legacy codecs, including Windows Media Video 7 and 8, Windows Media Screen 7, the older Microsoft MPEG-4 codecs, and the Microsoft ISO MPEG-4 codecs.This article uses bare URLs, which are uninformative and vulnerable to link rot. This codec is often used for software training or support by recording monitor images while computer applications are being used. Video codec optimized for encoding sequential screen shots from computer monitors. For content that is mixed music and speech, this codec can dynamically change the encoding algorithm used, to get optimal quality.Ī video codec that supports four categories of encoded content: Simple Profile, Main Profile, Advanced Profile, and Image. This is the preferred codec for streams consisting mostly of spoken words. CodecĪn audio codec that supports three categories of encoded content: Standard, Professional, and Lossless.Īudio codec optimized for encoding the human voice at high compression ratios. The following table describes the intended uses of the Windows Media codecs. The algorithms used to compress and decompress data for spoken words differ from the algorithms used to compress and decompress music data. Not only are there different codecs for audio and for video, but also different codecs for different kinds of content that you might want to put into an audio or video file. In some cases the COM objects occupy the same dynamically linked library (DLL).Įvery codec object implements two separate but similar interfaces: InterfaceĬompatible with Microsoft Media Foundation. A codec is usually implemented as a pair of COM objects: one for encoding content, and another for decoding content. The term codec is an amalgamation of the terms compressor and decompressor. For a technical overview of the features of the Windows Media codecs, see About the Windows Media Codecs. This documentation is primarily for developers who want to use Windows Media codecs in their C++-based media applications.
