Installation

You can use a release archive or build the CLI from the repository.

Release archive

Download the matching platform asset from the OpenJOC releases page. Extract it into a directory you control and put the CLI on your PATH, or invoke it by its full path.

The v0.16.0 release workflow targets macOS arm64, Windows x86_64, and GNU/Linux x86_64. Ecosystem packages have their own runtime and licensing boundaries; use the package quick-start material that ships with each archive.

Build from source

The workspace declares the Rust edition, version, repository, and minimum supported Rust version in the root Cargo.toml. From a clean checkout:

cargo build -p openjoc-cli --release --locked
./target/release/openjoc --version

On Windows, run the equivalent binary from target\\release\\openjoc.exe.

To install into a chosen prefix:

cargo install --path crates/openjoc-cli --locked --root /path/to/prefix

Input tools

Raw E-AC-3 input is handled by OpenJOC's bounded reader. Seekable ordinary MP4/M4A input uses the repository's container boundary and may require ffprobe or ffmpeg. Non-seekable and fragmented MP4 input is not admitted for the documented streaming path.

Windows LAV package

Windows playback through DirectShow is a separate optional package. It installs an OpenJOC-owned filter beside stock LAV and does not modify PotPlayer automatically. Follow Windows LAV / PotPlayer after extracting that package.

Check the installation

openjoc --help
openjoc self-test

self-test reports a missing optional public fixture as NOT_APPLICABLE; that result is not silent success for a fixture-dependent check.
