MP4 multiplexer and demultiplexer library

L-SMASH is a cross-platform library that handles the ISO base media file format and some of its derived file formats, including MP4. It operates as a multiplexer and demultiplexer, and can mux video and audio in several formats using standalone executable files.


Install the latest version of l-smash as follows:

guix install l-smash

Or install a particular version:

guix install l-smash@2.14.5

You can also install packages in augmented, pure or containerized environments for development or simply to try them out without polluting your user profile. See the guix shell documentation for more information.
