name	video_local_pipeline_and_mintable_export
description	Use for local-first media pipelines and self-contained mintable package exports with ffmpeg/wasm deployment safety and offline validation.

video_local_pipeline_and_mintable_export

Quick Start

1. Validate local toolchain (ffmpeg, ffprobe, runtime deps).
2. Ingest source media and generate segment/preview artifacts.
3. Build final self-contained package (no external runtime refs).
4. Verify offline playback and zero-console-error baseline.
5. Publish package manifest and mintability checklist.

When To Use

• Local-first video review, clip generation, and export workflows.
• Interactive HTML package creation for minting/distribution.
• Pipelines requiring ffmpeg and optional WASM runtime safety.

Inputs Required

• Source media paths and expected outputs.
• Packaging constraints (single-folder, asset budget, local-only behavior).
• Runtime context (desktop browser, hosted static, WASM-enabled path).
• QA acceptance criteria.

Workflow

1. Inspect media metadata and codec compatibility.
2. Run segmentation/preview/contact-sheet steps as required.
3. Generate final package assets and embed local references.
4. Validate runtime controls and playback states offline.
5. If hosted, apply WASM headers/MIME/deploy checks.
6. Produce manifest + artifact inventory + QA report.

Evidence-Backed Guardrails

• Keep outputs self-contained with relative/local references only.
• Treat toolchain checks (ffmpeg availability) as hard preconditions.
• Preserve source immutability in local review workflows.
• Validate compiled package behavior, not only editor/authoring preview.
• Capture screenshot/state artifacts and console health in final QA.

Reference Map

• references/mintable-package-checklist.md -> package integrity and mint readiness.
• references/wasm-runtime-checks.md -> hosted WASM safety checks.
• references/quality-checklist.md -> release gate.
• references/sandbox-evidence.md -> source evidence from Sandbox media projects.

Output Contract

Return:

• processing summary,
• produced artifacts and package path,
• offline playback verification,
• runtime/error validation summary,
• known limitations and next fixes.

Validation Checklist

• Package runs without network dependency.
• All referenced assets are present in package folder.
• Core controls (play/pause/seek/switch) are verified.
• Console/runtime errors are zero or explicitly documented.
• Package size and structure meet distribution constraints.

Failure Modes + Recovery

• Missing toolchain: install/verify ffmpeg stack and rerun.
• Broken local refs: rebuild bundle with strict relative-path validation.
• WASM load failures: fix MIME/headers and re-test hosted runtime.
• Editor/export mismatch: treat exported package as source of truth and patch build path.
