1. Introduction

YouJizz uses a custom player that exposes multiple encodings in JSON or inline JavaScript. Direct MP4 links and optional HLS manifests can be extracted from these payloads.

1.1 Research Scope

YouJizz watch pages and player configuration
Encodings arrays with multiple quality levels
Direct MP4 and optional HLS URLs

1.2 Methodology

Inspect inline scripts for encodings JSON
Capture network requests during playback
Validate media URLs with ffprobe

2. YouJizz Video Infrastructure Overview

2.1 Video Hosting Types

Direct MP4 hosting
Optional HLS playlists for adaptive streaming

2.2 CDN Architecture

Primary site domain: youjizz.com
Video assets hosted on CDN subdomains

2.3 Video Processing Pipeline

User loads watch page
Player script loads encodings JSON
Client chooses quality and requests MP4/HLS

2.4 Access Control and Authentication

Most public content is ungated
Some assets may require referer headers

3. URL Patterns and Detection

3.1 Watch Page URL Patterns

https://www.youjizz.com/videos/<slug>-<id>.html

3.2 Embed URL Patterns

https://www.youjizz.com/videos/embed/<id>

3.3 Direct Media and CDN URL Patterns

https://cdn.youjizz.com/videos/<id>/<quality>.mp4
https://cdn.youjizz.com/videos/<id>/master.m3u8

3.4 Regex Patterns for URL Extraction

youjizz\\.com/videos/.*-(\\d+)\\.html
encodings\\s*:\\s*\\[

3.5 Command-line URL Extraction

grep -oE "https?://[^'\" ]+\.(mp4|m3u8)" page.html | sort -u
grep -nE "encodings|videoUrl|hls" page.html

4. Stream Formats and CDN Analysis

4.1 Stream Formats

Format	Extension	Notes
MP4 (progressive)	.mp4	Multiple encodes per quality
HLS (adaptive)	.m3u8	Used for adaptive streaming when present

4.2 Typical Quality Ladder

Quality	Typical Resolution	Notes
Low	360p - 480p	Fast preview streams or mobile variants
Medium	720p	Common default for web playback
High	1080p+	Available when source uploads are higher quality

4.3 CDN URL Construction and Query Parameters

Encodings JSON usually contains URL and quality
Quality may be expressed in height or label

4.4 Validation and Inspection Commands

ffprobe -hide_banner -show_streams "video.mp4"

5. yt-dlp Implementation Strategies

yt-dlp can parse watch URLs directly when an extractor exists, or you can pass the direct MP4/HLS URL.

5.1 Basic Usage

yt-dlp [OPTIONS] [--] URL [URL...]
yt-dlp -F "https://example.com/watch/123"

5.2 Authentication and Cookies

Add referer headers if CDN returns 403

5.3 Format Selection and Output Templates

yt-dlp -f bestvideo+bestaudio/best "URL"
yt-dlp -o "%(title)s.%(ext)s" "URL"
yt-dlp --download-archive archive.txt "URL"

5.4 Site-Specific Examples

yt-dlp "https://www.youjizz.com/videos/<slug>-<id>.html"
yt-dlp -F "https://www.youjizz.com/videos/<slug>-<id>.html"
yt-dlp "https://cdn.youjizz.com/videos/<id>/<quality>.mp4"

5.5 Batch and Archive Mode

yt-dlp -a urls.txt --download-archive archive.txt
yt-dlp --no-overwrites --continue "URL"

5.6 Error Handling Patterns

Use --add-header 'Referer: https://www.youjizz.com/' for CDN assets

6. FFmpeg Processing Techniques

FFmpeg is best used for remuxing HLS playlists or validating MP4 outputs.

6.1 Inspect and Validate Streams

ffmpeg -i "https://cdn.youjizz.com/videos/<id>/master.m3u8" -c copy output.mp4

6.2 Common Remux and Repair Patterns

ffmpeg -i "playlist.m3u8" -c copy output.mp4
ffmpeg -i input.mp4 -c copy -movflags +faststart output.mp4
ffprobe -hide_banner -show_streams output.mp4

7. Alternative Tools and Backup Methods

7.1 Streamlink

streamlink "https://www.youjizz.com/videos/<slug>-<id>.html" best -o output.mp4

7.2 aria2c

aria2c -o video.mp4 "https://cdn.youjizz.com/videos/<id>/<quality>.mp4"

7.3 gallery-dl

gallery-dl "https://www.youjizz.com/videos/<slug>-<id>.html"

7.4 Browser DevTools

Search for encodings JSON in inline scripts
Look for mp4 URLs in Network tab

8. YouJizz API Integration

8.1 Known Endpoints

None documented; rely on page and player data extraction

8.2 Example Requests

# No public API calls identified; extract URLs from HTML/player data

8.3 Token and Session Handling

No public API documented; use player config payloads

9. Implementation Recommendations

9.1 Detection Hierarchy

Parse encodings array for MP4 URLs
Fallback to HLS playlist if available

9.2 Site-Specific Notes

Choose highest bitrate encode by resolution
Prefer MP4 for faster downloads

9.3 Storage and Naming Strategy

Use video ID in filenames

10. Troubleshooting and Edge Cases

Encodings array may be loaded via XHR; capture in Network tab

11. Conclusion

YouJizz provides multiple MP4 encodings and occasional HLS manifests in its player configuration. A robust downloader should parse the encodings array and select the best available URL, falling back to HLS when needed.

Tool	Best Use Case	Notes
yt-dlp	Primary downloader for MP4/HLS	Supports cookies, format selection, retries
ffmpeg	Remuxing and validation	Useful for HLS to MP4 conversion
streamlink	Live/HLS fallback	Streams to file or pipes into ffmpeg
aria2c	Multi-connection HTTP/HLS downloads	Good for large files and retries
gallery-dl	Image-first or gallery-heavy sites	Best for gallery or attachment extraction
