yt-dlp HLS Proxy

A simple Flask proxy server that uses yt-dlp to fetch HLS streams and serves them through a web player.

Features

• HLS stream proxying via yt-dlp
• In-memory caching (365 days TTL by default)
• URL validation with allowed domains
• HTML5 video player with hls.js
• Configurable via environment variables
• Full metadata display (title, description, views, likes, tags, etc.)

Quick Start

pip install -r requirements.txt
python app.py

Visit http://localhost:5000 and enter a video URL.

Configuration

Variable	Default	Description
PORT	5000	Server port
LOG_LEVEL	INFO	Logging level
CACHE_TTL	31536000	Cache TTL in seconds (365 days)
SOCKET_TIMEOUT	30	Socket timeout for requests
VALIDATION_ENABLED	true	Enable URL validation
ALLOWED_DOMAINS	youtube.com,youtu.be,pornhub.com,xvideos.com	Allowed video domains
ALLOW_LOCAL	true	Allow localhost/127.0.0.1 URLs (for testing)

Routes

• / - Home page with video URL input
• /player?url=VIDEO_URL - Video player page with full metadata
• /hls/<encoded_url>--index.m3u8 - HLS main playlist
• /hls/<encoded_url>--<segment>.ts - HLS segment

Connecting External Player

URL Format

The proxy uses this format: /hls/<encoded_video_url>--<filename>

Example for PornHub:

/hls/https%3A%2F%2Frt.pornhub.com%2Fview_video.php%3Fviewkey%3D69c13273df690--index.m3u8

Using with yt-dlp (as browser substitute)

# Get playlist URL via proxy
yt-dlp --hls-use-mpegts --no-download --print url \
  "http://localhost:5000/hls/https%3A%2F%2Frt.pornhub.com%2Fview_video.php%3Fviewkey%3D69c13273df690--index.m3u8"

Using with VLC

1. Open Network Stream (Ctrl+N)
2. Enter: http://localhost:5000/hls/<encoded_url>--index.m3u8

Using with mpv

mpv "http://localhost:5000/hls/https%3A%2F%2Frt.pornhub.com%2Fview_video.php%3Fviewkey%3D69c13273df690--index.m3u8"

Using with any HLS-compatible player

Most players accept the m3u8 URL directly:

http://localhost:5000/hls/<encoded_video_url>--index.m3u8

Where <encoded_video_url> is the URL-encoded original video URL.

Example - full URL:

http://localhost:5000/hls/https%3A%2F%2Frt.pornhub.com%2Fview_video.php%3Fviewkey%3D69c13273df690--index.m3u8

Python example (using requests + hlsjs)

import requests

video_url = "https://rt.pornhub.com/view_video.php?viewkey=69c13273df690"
from urllib.parse import quote
encoded = quote(video_url, safe="")
hls_url = f"http://localhost:5000/hls/{encoded}--index.m3u8"

response = requests.get(hls_url)
print(response.text)  # Contains rewritten segment URLs

Running with Gunicorn

gunicorn -w 4 -b 0.0.0.0:5000 app:app
