Quick One-Liners

# Best quality video
yt-dlp -f "bv*+ba/b" "URL"

# 1080p video + subtitles
yt-dlp -f "bv[height<=1080]+ba/b" --write-subs --sub-langs "en,zh" "URL"

# Extract audio as MP3
yt-dlp -x --audio-format mp3 "URL"

# Download YouTube playlist
yt-dlp --yes-playlist "URL"

# Fast file download (16 connections)
aria2c -x16 -s16 -k1M "URL"

# Download magnet
aria2c --seed-time=0 "magnet:?xt=..."

# Batch images from gallery
gallery-dl "URL"

# Spotify album → local MP3s
spotdl "SPOTIFY_URL"

# All PDFs from a page
wget -r -l1 -A "*.pdf" "URL"

# Video metadata as JSON (automation)
yt-dlp -j "URL"

# Get direct URL without downloading
yt-dlp -g "URL"

Agent Automation Patterns

Video pipeline: yt-dlp -j URL → parse JSON → select format → yt-dlp -f FORMAT URL -o OUTPUT

Ebook search: Search Anna's Archive / Z-Library / 鸠摩搜书 → get download page → extract link → aria2c

Bulk media: gallery-dl --dump-json URL → review items → gallery-dl -d OUTPUT URL

Music: spotdl SPOTIFY_URL (auto YouTube match + metadata) or yt-dlp -x --audio-format mp3 YOUTUBE_URL

Domain Instability

Many resource sites rotate domains. When a URL fails:

Search: [site name] mirror 2026 or [站名] 最新地址
Check Reddit/Twitter for community mirror lists
Anna's Archive = most resilient ebook meta-search
For Chinese cloud search: check 网盘之家导航 for latest links
