Versions:
Shaka Packager version 3.7.1, released by the Shaka Project, is a command-line media-packaging and development framework engineered to prepare both live and video-on-demand streams for modern adaptive-bitrate delivery. The tool ingests audio/video elementary streams or multiplexed files and outputs ISO-BMFF (MP4/CMAF) or MPEG-2 Transport Stream segments that are fully compliant with the DASH and HLS specifications, while simultaneously generating the corresponding MPD or m3u8 manifests. Its built-in Common Encryption (CENC) module enables studio-grade DRM insertion, supporting Google Widevine, Microsoft PlayReady, Marlin and other systems that share the CENC scheme, so the same set of segments can be served to multiple client ecosystems without re-packaging. Developers use Shaka Packager to create test vectors, build origin servers, automate content-preparation pipelines, and prototype streaming workflows; DevOps teams embed it in CI/CD chains to encrypt, subtitle, thumbnail and package thousands of assets overnight. Because the code is modular and exposes a library API, researchers also employ it as a sandbox for experimenting with low-level container tweaks, new codec support, or emerging CMAF profiles. The project maintains six numbered releases, of which 3.7.1 is the current stable point, offering incremental fixes for segment alignment, key-rotation signalling and HLS byte-range optimisation. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
