Feature Specification — YouTubeDownloader with serial.YoutubeMusicDown

Overview

  • Build a robust command-line and library feature named serial.YoutubeMusicDown that downloads audio from YouTube (videos and YouTube Music), supports batch processing, metadata tagging, rate-limiting, resume/retry, and integrates with a serializable job queue ("serial" prefix refers to serializable job objects for persistence and reproducible runs).

Goals

  • Reliable audio extraction and conversion to MP3/AAC/FLAC.
  • Preserve/attach metadata (title, artist, album, artwork, track number).
  • Support playlists, channels, and individual URLs.
  • Resume partially downloaded jobs; idempotent operations.
  • Configurable concurrency, bandwidth throttling, and retry/backoff policies.
  • CLI + Python library API with well-documented, testable behavior.
  • Secure handling of file paths, quota, and user-provided data.
  • Extensible plugin hooks for post-processing, cloud upload, or tagging.

Architecture

  • Components:
    • Job model: serializable job object capturing input URLs, desired format, settings, state, progress, timestamps, and unique job ID.
    • Job Store: persistent storage (SQLite + local filesystem) for serialized jobs and checkpoints.
    • Downloader Engine: orchestrates downloads, concurrency, retries, and uses worker pool.
    • Extractor: wraps youtube-dl / yt-dlp or native extraction code to fetch best audio streams / DASH manifests.
    • Converter: uses ffmpeg for conversion, normalization, clipping metadata embed.
    • Tagger: writes ID3/MP4 tags, embeds cover art, uses MusicBrainz/AcoustID lookup optionally.
    • CLI: user-facing commands for enqueue, status, resume, cancel, list, config.
    • Library API: Job creation, execution, progress callbacks, and hooks.
    • Plugins: post-upload (S3, Google Drive), notification (desktop, email), custom metadata enrichers.
    • Security layer: sandboxing ffmpeg calls, validate URLs, sanitize filenames, and safe temp directories.

Data Model — Job (serializable)

  • id: UUIDv4
  • input: list of source objects type: "url"/"playlist"/"channel", value: string
  • format: "mp3" | "aac" | "flac" | "m4a" | "wav"
  • bitrate: e.g., 320k or "best"
  • normalize: boolean (apply loudness normalization)
  • metadata: title, artist, album, track, year, genre, artwork_url
  • options: split_chapters, embed_subtitles, lyrics, auto_track_numbering
  • state: "queued" | "downloading" | "converting" | "tagging" | "completed" | "failed" | "cancelled"
  • progress: current_index, total, bytes_downloaded, total_bytes, percent
  • retries: integer
  • created_at, updated_at, completed_at, last_error
  • backoff_policy: max_retries, base_delay, max_delay
  • user_id: optional (for multi-user setups)
  • output_path_template: e.g., "artist/album/track:02d - title.ext"
  • extra: freeform map for plugins

Job Store

  • SQLite table mapping job id to JSON blob, index on state and created_at.
  • Checkpoint files for in-progress downloads (e.g., partial .part files), with atomic rename when finished.
  • Housekeeping: periodically remove or archive old completed jobs; configurable retention.

Downloader Engine

  • Worker pool (configurable size, default 4).
  • Per-worker bandwidth limiter using token-bucket to throttle downloads.
  • Concurrency controls for same-source protection (avoid hammering a single channel).
  • Queue prioritization (priority numeric; FIFO for equal priority).
  • Graceful shutdown: workers persist checkpoints and update job state.
  • Resume logic: if a partial .part file exists, resume using extractor's continuation flags or HTTP range requests.

Extractor

  • Default backend: yt-dlp via subprocess or library API (configurable).
  • Fallback: native DASH hls extraction if yt-dlp fails.
  • Pre-flight probe: obtain metadata and available formats before downloading.
  • Select audio-only stream if available; otherwise extract best audio track.
  • Handle age-restricted, region-restricted content via user-supplied cookies or OAuth tokens (securely read from config, never persisted in job JSON).
  • Emit progress events: bytes, speed, eta.

Converter

  • ffmpeg subprocess with safe argument quoting; temp files in dedicated temp dir.
  • Support copy stream (no re-encode) when target is compatible; otherwise re-encode with libmp3lame/libfdk_aac/libvorbis/FLAC.
  • Optional loudness normalization (EBU R128).
  • Optional volume boost or clipping avoidance.
  • Split chapters into tracks if requested.

Tagger Metadata

  • Use extracted metadata; if missing, use heuristic from filename or web scrape.
  • Optional MusicBrainz query to enrich artist/album data; optional AcoustID fingerprinting for identification.
  • ID3v2.4 tagging for MP3; MP4 tags for M4A; Vorbis comments for FLAC.
  • Embed cover art: download artwork_url or fetch highest resolution thumbnail.
  • Preserve original URL in a dedicated tag (e.g., TIT3 or TXXX) for provenance.
  • Support piping lyrics and subtitles into tags when present.

CLI Design

  • Commands:
    • serial-ytdown add [URL|file] --format mp3 --bitrate 320k --out-template "artist/title.ext" --priority 10
    • serial-ytdown status [JOB_ID|--all]
    • serial-ytdown start [--workers N]
    • serial-ytdown resume JOB_ID
    • serial-ytdown cancel JOB_ID
    • serial-ytdown list --state queued,downloading
    • serial-ytdown config set|get
    • serial-ytdown export-job JOB_ID --json
  • Output: concise tabular status in terminal; JSON output option for scripts.
  • Config file: YAML or TOML (~/.config/serial-ytdown/config.toml).

Library API (Python)

  • from serial.ytdown import Job, Engine, JobStore
  • job = Job.from_urls(["https://..."], format="mp3", bitrate="320k")
  • store.save(job)
  • engine = Engine(store, workers=4, concurrency=2)
  • engine.run() # blocking
  • engine.start_background() # non-blocking with callbacks
  • engine.on_progress(job_id, callback) # register callback
  • engine.shutdown(graceful=True)

Progress & Observability

  • Emit structured progress events via UNIX domain socket, gRPC, or websocket, with JSON schema.
  • Metrics exportable to Prometheus: queue_length, jobs_completed_total, jobs_failed_total, current_workers, bytes_downloaded_total.
  • Optional Sentry integration for errors.
  • Logging: structured JSON logs with rate-limited noise from ffmpeg/yt-dlp.

Error Handling & Retries

  • Differentiate transient (network, 5xx) vs permanent (DRM, removed video).
  • Retries use job.backoff_policy; exponential backoff with jitter.
  • If extractor reports unavailable format, attempt conversion pipeline or mark as failed with clear reason.
  • Automatic blacklist for sources causing repeated failures.

Security & Safety

  • Sanitize output paths: remove traversal, control characters; limit path length.
  • Run external binaries with limited environment and resource limits (setrlimit for CPU/time if supported).
  • Validate downloaded files via checksum or duration sanity checks.
  • Optionally run conversion within a container or isolated user.
  • Do not store credentials in job JSON; reference secure credential store.

Storage & Disk Management

  • Configurable storage root; per-job quota and global quota enforcement.
  • Auto-pruning policy: keep N newest or M GB, delete older completed jobs.
  • Deduplication: hash audio content and store shared blobs; jobs reference blobs to save space.

Testing Strategy

  • Unit tests: Job serialization, path sanitization, retry/backoff, tag writing.
  • Integration tests: with yt-dlp and ffmpeg in CI using sample fixtures (mock HTTP and small test media).
  • Fuzz tests: weird titles, emojis, surrogate pairs in metadata.
  • Performance tests: large playlist download, concurrency limits, throttling correctness.

Deployment & Distribution

  • Distribute as pip package with optional extras: "serial.ytdown[ffmpeg,yt-dlp,musicbrainz]".
  • Prebuilt binaries for macOS/Linux via PyInstaller or static builds.
  • Docker image with entrypoint for daemon and CLI.
  • Systemd unit file example for background service.

UX Considerations

  • Default safe settings for filesystem (no overwrites; prompt or add suffix).
  • Respect YouTube terms; warn users about copyrighted content and legal use.
  • Clear error messages with suggested remediation (e.g., "provide cookies file for age-restricted content").

Example Job JSON "id": "c3f4d2b8-... ", "input": ["type":"url","value":"https://www.youtube.com/watch?v=abc"], "format":"mp3", "bitrate":"320k", "state":"queued", "progress":"current_index":0,"total":1,"bytes_downloaded":0,"percent":0, "output_path_template":"artist/title.ext"

Implementation Notes & Priorities

  • Phase 1 (MVP): Job model, CLI add/status, yt-dlp extractor integration, ffmpeg conversion, basic tagging, SQLite job store, single-worker engine, resume support.
  • Phase 2: Concurrency, throttling, plugin system, metadata enrichment, MusicBrainz integration.
  • Phase 3: Distributed queue, cloud plugin, GUI front-end, content deduplication, strong sandboxing.

API Examples (Python)

from serial.ytdown import Job, Engine, JobStore
store = JobStore('~/.serial-ytdown/jobs.db')
job = Job.create(urls=['https://www.youtube.com/watch?v=...'], format='mp3', bitrate='320k')
store.save(job)
engine = Engine(store, workers=2)
engine.start_background()

Acceptance Criteria

  • Downloads audio and produces correct file with embedded metadata for single video, playlist, and channel inputs.
  • Jobs survive process restarts and can resume from partial downloads.
  • Configurable concurrency and throttling behave as specified.
  • Tagging correctly embeds metadata and artwork for common cases.
  • Tests covering at least 80% of core logic.

Roadmap (short)

  • 0–1 month: MVP features and tests.
  • 1–3 months: Concurrency, plugins, MusicBrainz/AcoustID.
  • 3–6 months: Packaging, Docker, performance tuning, UI prototype.
