rdlp

A video downloader that extracts metadata and media from supported sites, downloads via HTTP, HLS, or DASH with parallel chunking, and post-processes with FFmpeg library bindings. Inspired by yt-dlp.

Features

• HTTP, HLS, and DASH (static VoD) downloads with resume support
• Parallel chunked transfers with adaptive controller
• FFmpeg-based post-processing (remux, transcode, audio extraction, metadata/thumbnail embedding)
• Audio normalization (peak / EBU R128 loudnorm) with limiter-boost fallback
• Subtitle download, format conversion, and embedding
• yt-dlp-compatible format selection and output templates
• Browser cookie extraction (Chrome, Firefox) and Netscape cookie files
• Browser TLS fingerprint impersonation for sites that block other downloaders
• Keyword search across supported sites with filters (13 search-capable extractors)
• Signed WASM plugin system for adding new sites without recompiling
• Rate limiting, download archive, JSON metadata export
• Interactive format and container selection

Supported Sites

PornHub, XHamster, RedTube, HQPorner, XTits, TNAFlix, EMPFlix, MovieFap, NineAnime, KoreanPornMovie, XVideos, XNXX, EPorner, ABXXX, plus a generic fallback extractor.

See rdlp --list-extractors for the current list.

Building

Requires Rust 1.85+ and FFmpeg shared libraries.

git clone https://github.com/crippledgeek/rdlp.git
cd rdlp
cargo build --release                    # library crates only
cargo build --release -p rdlp-cli        # CLI binary
cargo build --release -p rdlp-desktop    # Tauri desktop app
cargo build --release --workspace        # everything

The workspace uses default-members so cargo build compiles only library crates. Use -p to target a specific binary.

See BUILDING.md for platform-specific FFmpeg setup and troubleshooting.

Usage

rdlp URL                              # download best quality
rdlp -i URL                           # interactive format selection
rdlp --remux=mp4 URL                  # remux to MP4
rdlp -f "bv[height<=720]+ba" URL      # format selection
rdlp --audio-multistreams URL         # use bv+ba/b instead of bv*+ba/b
rdlp -x --audio-format=flac URL       # extract audio
rdlp --cookies-from-browser chrome URL # use browser cookies
rdlp --dump-json URL                  # metadata as JSON
rdlp --search "query" --search-site redtube  # keyword search

Run rdlp --help for the full option list.
