Virtual package installing liquidsoap dependencies for SDL optional features


Dune Dependency






Liquidsoap is a swiss-army knife for multimedia streaming, notably used for netradios and webtvs. It has tons of features, it's free and it's open-source!

Liquidsoap is a powerful and flexible language for describing your streams. It offers a rich collection of operators that you can combine to create and transform streams. Liquidsoap is very light and easy to use, in the Unix tradition of simple strong components working together.

Release Details

Current release status by version: | Branch | Latest release | Supported | Rolling Release | | --------|----------------|-----------|-----------------| | 2.2.x | In development | ✅ | 2.2.x (docker: savonet/liquidsoap:rolling-release-v2.2.x) | | 2.1.x | 2.1.4 (docker: savonet/liquidsoap:v2.1.4| 🌅 | 2.1.x (docker: savonet/liquidsoap:rolling-release-v2.1.x) | | 2.0.x | 2.0.7 | ❌ | 2.0.x | | 1.4.x | 1.4.4 | ❌ | ❌ |


  • Development branch 2.2.x is being prepared for its first stable release. We do encourage new projects to start with it and users to report issues. We will prioritize these issues over other ones.

  • Development branch 2.1.x is nearing the end of its development cycle and will only be updated on a best effort basis or in case of a major issue.


Liquidsoap releases follow a semantic versioning as follows:



  • major_version is bumped when there are major changes, i.e. changes in the paradigm, major implementation change etc. Versions with different major versions are incompatible

  • minor_version is bumped when there are minor changes, i.e. new operators, renaming, new modules etc. Version with different minor versions may be incompatible

  • bugfix_version is bumped when a new bugfix version is published. Versions with only bugfix version changes should be compatible

Please note that liquidsoap is a complex framework with a lot of operators and advanced implementations. For this reason, it is possible that a bugfix actually fixes the behavior of an operator the way it was intended to be and may break scripts that previously relied on incorrect implementations.

Therefore, we strongly recommend maintaining a staging environment that makes it possible to test new versions before using them in production. In this context, the semantic versioning above should guide you in knowing how much scrutiny you should put into a new release before validating it in your staging environment.


Release assets are provided at: Published, versioned releases are available using their published tag, i.e. vx.y.z.

We also provide rolling releases. A rolling release is a snapshot of a current, unpublished release. It can be a future stable release or a future bugfix release for a given major/minor version.

For both types of releases, we reserve the right to update, delete and add assets to the release at any time. If you are looking for permanent links to release assets, you should grab them from, which reflects all our releases but whose artifacts are never modified/deleted.


HTML documentation is available on our website

We also have written the Liquidsoap book which is available online and in physical version.


Contributions are more than welcome: you can submit issues if you find some, or contribute to the code through pull requests. You can checkout the code with

git checkout

To build the code, you will need all the required opam packages installed. You can do it this way:

cd liquidsoap/
opam pin git+
opam pin git+
opam pin git+
opam pin git+ # optional
opam pin -ny .
opam install --deps-only liquidsoap

You might also need to pin a local version of the OCaml modules that we maintain in relation to liquidsoap. This can be done by pinning that module locally using opam.

Assuming that all dendencies are installed, you can now build with

dune build

In order to ensure the quality of your commits, you are recommended to install the pre-commit hooks with

pre-commit install

Those will automatically check before each commit that those meet some of our quality requirements.
