Geographic Restrictions: Region-based content blocking
Age Verification: Adult content access controls

3. Embed URL Patterns and Detection

3.1 Primary Embed Patterns

3.1.1 Standard Video URLs

https://www.tnaflix.com/cum-videos/{VIDEO_TITLE}/{VIDEO_ID}
https://www.tnaflix.com/embed/{VIDEO_ID}
https://player.tnaflix.com/video/{VIDEO_ID}

3.1.2 Direct Video Stream URLs

https://static.tnaflix.com/contents/videos_sources/{VIDEO_ID}/file.mp4
https://cdn.tnaflix.com/contents/videos/{VIDEO_ID}/{QUALITY}.mp4
https://media.tnaflix.com/videos/{VIDEO_ID}/playlist.m3u8

3.1.3 Mobile and Progressive URLs

https://m.tnaflix.com/video/{VIDEO_ID}
https://www.tnaflix.com/ajax/video-player-url/{VIDEO_ID}

3.2 Video ID Extraction Patterns

3.2.1 Standard Format

/video/([0-9]+)/
/embed/([0-9]+)/
tnaflix\.com/[^/]+/([0-9]+)

3.2.2 URL Parameter Format

video_id=([0-9]+)
v=([0-9]+)
id=([0-9]+)

3.3 Detection Implementation

Command-line Detection Methods

Using grep for URL pattern extraction:

# Extract TNAflix video IDs from HTML files
grep -oE "https?://(?:www\.)?tnaflix\.com/[^/]+/[^/]+/([0-9]+)" input.html

# Extract from multiple files
find . -name "*.html" -exec grep -oE "tnaflix\.com/[^/]+/[0-9]+" {} +

# Extract video IDs only (without URL)
grep -oE "tnaflix\.com/[^/]+/([0-9]+)" input.html | grep -oE "[0-9]+"

Using yt-dlp for detection and metadata extraction:

# Test if URL contains downloadable video
yt-dlp --dump-json "https://www.tnaflix.com/cum-videos/title/{VIDEO_ID}" | jq '.id'

# Extract all video information
yt-dlp --dump-json "https://www.tnaflix.com/embed/{VIDEO_ID}" > video_info.json

# Check if video is accessible
yt-dlp --list-formats "https://www.tnaflix.com/cum-videos/title/{VIDEO_ID}"

Browser inspection commands:

# Using curl to inspect embed pages
curl -s -H "User-Agent: Mozilla/5.0 (compatible)" "https://www.tnaflix.com/embed/{VIDEO_ID}" | grep -oE "video_url.*mp4"

# Inspect page headers for video information
curl -I "https://www.tnaflix.com/embed/{VIDEO_ID}"

# Extract JavaScript variables containing video URLs
curl -s "https://www.tnaflix.com/embed/{VIDEO_ID}" | grep -oE "videoUrl\s*=\s*['\"][^'\"]*['\"]"

# 4. Play the TNAflix video
# 5. Copy URLs from network requests

# Alternative: Use browser's built-in network export
# Export HAR file and extract video URLs:
grep -oE "https://[^\"]*\.(mp4|m3u8)" network_export.har | grep -i tnaflix

7.4.2 Automated Browser Scraping

# Using puppeteer for adult content scraping
node -e "
const puppeteer = require('puppeteer');
(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.setUserAgent('Mozilla/5.0 (compatible; TNAflix-Bot)');
  await page.evaluateOnNewDocument(() => {
    Object.defineProperty(navigator, 'webdriver', { get: () => false });
  });
  
  const responses = [];
  page.on('response', response => {
    if (response.url().includes('.mp4') || response.url().includes('.m3u8')) {
      responses.push(response.url());
    }
  });
  
  await page.goto('https://www.tnaflix.com/embed/{VIDEO_ID}');

8. Implementation Recommendations

8.1 Primary Implementation Strategy

8.1.1 Hierarchical Command Approach

Use a sequential approach with different tools, optimized for adult content:

#!/bin/bash
# Primary download strategy script for TNAflix

download_tnaflix_video() {
    local video_url="$1"
    local output_dir="${2:-./downloads}"
    local quality="${3:-720p}"
    
    echo "Attempting download of: $video_url"
    
    # Method 1: yt-dlp (primary) with adult content settings
    if yt-dlp --age-limit 18 --add-header "Referer:https://www.tnaflix.com/" \
              --ignore-errors -o "$output_dir/%(title)s.%(ext)s" "$video_url"; then
        echo "✓ Success with yt-dlp"
        return 0
    fi
    
    # Method 2: gallery-dl (specialized for adult content)
    if gallery-dl -d "$output_dir" "$video_url"; then
        echo "✓ Success with gallery-dl"
        return 0
    fi
    
    # Method 3: Direct URL extraction and wget
    video_id=$(echo "$video_url" | grep -oE "[0-9]+")
    if [ -n "$video_id" ]; then
        direct_url="https://static.tnaflix.com/contents/videos_sources/$video_id/$quality.mp4"
        if wget --header="Referer: https://www.tnaflix.com/" \
                --header="User-Agent: Mozilla/5.0 (compatible)" \
                -O "$output_dir/tnaflix_$video_id.mp4" "$direct_url"; then
            echo "✓ Success with direct download"
            return 0
        fi
    fi
    
    # Method 4: ffmpeg with stream URL
    if [ -n "$video_id" ]; then
        stream_url="https://media.tnaflix.com/videos/$video_id/playlist.m3u8"
        if ffmpeg -headers "Referer: https://www.tnaflix.com/" \
                  -i "$stream_url" -c copy "$output_dir/tnaflix_$video_id.mp4"; then
            echo "✓ Success with ffmpeg"
            return 0
        fi
    fi
    
    echo "✗ All methods failed"
    return 1
}

8.2 Quality Selection with Adult Content Considerations

# Inspect available qualities first
yt-dlp -F "https://www.tnaflix.com/embed/{VIDEO_ID}"

# Download with quality preference and size limits
yt-dlp -f "best[height<=720][filesize<300M]/best[height<=480]/best" "https://www.tnaflix.com/embed/{VIDEO_ID}"

# Adult content specific quality selection
select_quality_adult() {
    local video_url="$1"
    local max_quality="${2:-720}"
    local max_size_mb="${3:-300}"
    
    echo "Checking available formats for adult content..."
    yt-dlp --age-limit 18 -F "$video_url"
    
    echo "Downloading with quality limit: ${max_quality}p, size limit: ${max_size_mb}MB"
    yt-dlp --age-limit 18 \
           --add-header "Referer:https://www.tnaflix.com/" \
           -f "best[height<=$max_quality][filesize<${max_size_mb}M]/best[height<=$max_quality]/best" \
           "$video_url"
}

9. Troubleshooting and Edge Cases

9.1 Adult Content Specific Issues

9.1.1 Age Verification and Access Control

# Test age verification status
test_age_verification() {
    local url="$1"
    
    echo "Testing age verification for: $url"
    
    # Test without age verification
    local status_no_age=$(curl -o /dev/null -s -w "%{http_code}" "$url")
    echo "Without age verification: $status_no_age"
    
    # Test with age verification cookie
    local status_with_age=$(curl -o /dev/null -s -w "%{http_code}" \
                           -H "Cookie: age_verified=1" "$url")
    echo "With age verification: $status_with_age"
    
    # Test with full adult content headers
    local status_full_headers=$(curl -o /dev/null -s -w "%{http_code}" \
                               -H "Cookie: age_verified=1; content_filter=off" \
                               -H "Referer: https://www.tnaflix.com/" \
                               -H "User-Agent: Mozilla/5.0 (compatible)" "$url")
    echo "With full headers: $status_full_headers"
}

# Bypass age verification
bypass_age_verification() {
    local url="$1"
    local output_dir="${2:-./downloads}"
    
    # Method 1: Use pre-verified session
    if yt-dlp --cookies-from-browser firefox "$url"; then
        echo "✓ Success with browser cookies"
        return 0
    fi
    
    # Method 2: Manual cookie injection
    if yt-dlp --add-header "Cookie: age_verified=1; nsfw_allowed=1" "$url"; then
        echo "✓ Success with manual cookies"
        return 0
    fi
    
    # Method 3: Direct embed URL
    local video_id=$(echo "$url" | grep -oE "[0-9]+")
    if [ -n "$video_id" ]; then
        local embed_url="https://www.tnaflix.com/embed/$video_id"
        if yt-dlp "$embed_url"; then
            echo "✓ Success with embed URL"
            return 0
        fi
    fi
    
    echo "✗ Age verification bypass failed"
    return 1
}

9.2 Performance and Privacy Issues

9.2.1 Secure download with privacy protection

secure_adult_download() {
    local url="$1"
    local output_dir="${2:-./secure_downloads}"
    
    # Create secure directory
    mkdir -p "$output_dir"
    chmod 700 "$output_dir"
    
    # Download with privacy settings
    yt-dlp --no-cookies \
           --no-cache-dir \
           --rm-cache-dir \
           --add-header "DNT:1" \
           --add-header "Referer:https://www.tnaflix.com/" \
           --age-limit 18 \
           -o "$output_dir/%(title)s.%(ext)s" \
           "$url"
    
    # Remove metadata from downloaded files
    for file in "$output_dir"/*.mp4; do
        if [ -f "$file" ]; then
            echo "Removing metadata from: $file"
            ffmpeg -i "$file" -map_metadata -1 -c copy "${file%.mp4}_clean.mp4"
            shred -vfz -n 3 "$file"  # Secure delete original
            mv "${file%.mp4}_clean.mp4" "$file"
        fi
    done
    
    echo "✓ Secure download completed with privacy protection"
}
