Since version 1.4.9, the LiVES video editor has support for realtime decoding and for encoding to WebM format using ffmpeg libraries. MPC-HC since build SVN 2071 supports WebM playback with internal VP8 decoder based on FFmpeg's code. [25] [28] The full decoding support for WebM is available in MPC-HC since version 1.4.2499.0. [29]
GIF.gif N/A N/A none Simple animation, inefficient compression, no sound, widely supported Video alternative to GIF.gifv HTML any none Not standardized, and not a real video file in the classical meaning since it merely references the real video file (e.g. a .webm file), which has to exist separately elsewhere.
Digital 3D is only supported at the container format level in Matroska, [41] MXF [43] and WebM (some stereo modes). [39] M2TS supports Digital 3D as multiple files in a specific file structure for encoding stereoscopic video: MVC stereoscopic data is in .ssif files in the /BDMV/STREAM/SSIF/ directory and require a respective base .m2ts file.
FFmpeg is a free and open-source software project consisting of a suite of libraries and programs for handling video, audio, and other multimedia files and streams. At its core is the command-line ffmpeg tool itself, designed for processing video and audio files.
FFmpeg linked with the VP8/VP9 reference codec library libvpx can extract VP8 key frames from WebM media and a script can then add the WebP RIFF header and the NUL pad byte for odd frame lengths. Meanwhile, FFmpeg supports libwebp directly. Gmail and Google Photos both support WebP. Support for WebP is also planned for Google App Engine.
Video converters are computer programs that can change the storage format of digital video. They may recompress the video to another format in a process called transcoding, or may simply change the container format without changing the video format.
[10] [11] The output options for the 2017 version included Apple ProRes, HDV, DVD, Flash, H.264, GIF animation, Ogg-Vorbis, WebM, and WMV.
