DRM Offline Packager 2.1

DRM Offline Packager is a secure, on‑premises packaging tool that encrypts and packages pre‑encoded video and audio for distribution without an internet connection. Built for air‑gapped or high‑security environments, it streamlines the creation of HLS and DASH deliverables using industry‑standard common encryption, while keeping keys and assets under your control.

Key features

• True offline operation: run in air‑gapped networks with no external dependencies.
• Standards‑based packaging: outputs CMAF/fMP4 segments with DASH (MPD) and HLS (M3U8) manifests.
• Multi‑DRM ready: uses Common Encryption (cenc/cbcs) and generates PSSH and related signaling; supports SAMPLE‑AES for legacy HLS when required.
• Flexible key management: import KIDs/keys, use local KMS/HSM via PKCS#11, configure clear lead and key rotation.
• Input/Output: ingests pre‑encoded fragmented MP4/MP4/TS and produces aligned ABR ladders for DASH and HLS.
• Automation friendly: CLI and optional local API, JSON job specs, watch‑folder workflows, parallel batch processing.
• Validation and QC: manifest and segment integrity checks, bitrate/ladder alignment, checksum reports.
• Security controls: role‑based access, audit logs, optional tamper‑evident logging, secure key handling and zero‑retention modes.
• Deployment options: standalone binary or containerized; runs on common Linux and Windows environments.
• Deterministic outputs for reproducible builds and predictable caching behavior.

Typical workflow

1. Import pre‑encoded assets and the desired ABR ladder/profile.
2. Supply keys/KIDs or connect to a local KMS/HSM.
3. Select packaging profiles (HLS, DASH, CMAF) and encryption settings.
4. Run the job offline; review validation and compliance reports.
5. Export packaged assets and manifests for transfer to your CDN or delivery system.

Compatibility highlights

• Formats: DASH (ISO BMFF), HLS (TS or CMAF/fMP4).
• Encryption: CENC (cenc/cbcs), SAMPLE‑AES for HLS where applicable.
• Codecs: pass‑through for common codecs such as H.264/AVC, H.265/HEVC, AAC, and Dolby Digital Plus (no transcoding).

Use cases

• Studio-grade on‑prem packaging
• Broadcaster and OTT operations
• In‑flight, maritime, and other disconnected or secure deployments
• Disaster recovery and business‑continuity workflows
• Secure prepositioning and review/approval deliverables

Notes

• DRM license servers and content keys are not included; integration with your chosen DRM provider is required for playback.
• Ensure you have the necessary rights and licenses for all protected content and cryptographic modules.
• Feature availability may vary by platform and configuration; consult your documentation for the detailed compatibility matrix.
