FFMPEG HWACCEL FIX

FFmpeg Hardware Acceleration Fix - MPEG-4 Codec Issue

Issue

When streaming Magnum P.I. Season 1 episodes (AVI files with MPEG-4/DivX/XviD codec), FFmpeg fails with:

ERROR - FFmpeg: [mpeg4 @ 0xc560ea300] Failed setup for format videotoolbox_vld: 
hwaccel initialisation returned error.

Root Cause

VideoToolbox (macOS hardware acceleration) does NOT support older codecs:

  • ❌ MPEG-4 (DivX, XviD)
  • ❌ MPEG-2
  • ❌ Some other legacy codecs

VideoToolbox ONLY supports:

  • ✅ H.264 (common in modern MP4 files)
  • ✅ H.265/HEVC
  • ✅ ProRes (on M-series chips)

The Problem with Mixed Collections

Magnum P.I. collection has:

  • Season 1: AVI files with MPEG-4/DivX codec ❌ (not supported by VideoToolbox)
  • Seasons 2-8: MP4 files with H.264 codec ✅ (supported by VideoToolbox)

When hardware acceleration is enabled globally, Season 1 episodes fail to decode.

Fix Applied

Solution: Disable Hardware Acceleration

Updated: config.yaml

Before:

ffmpeg:
  hwaccel: videotoolbox  # Fails on MPEG-4 files

After:

ffmpeg:
  hwaccel: null  # Disabled for universal codec support

Why This Works

  • Software decoding supports ALL codecs
  • Reliable for mixed format collections
  • Universal compatibility
  • Slight CPU increase (usually minimal on modern Macs)

Alternative Solutions

Option 1: Conditional Hardware Acceleration (Advanced)

If you want hardware acceleration for supported formats:

You would need to:

  1. Detect codec before streaming
  2. Enable hwaccel only for H.264/HEVC
  3. Use software decoding for MPEG-4/DivX

This requires code changes to detect codec per video.

Option 2: Use Auto-Fallback (Not Fully Reliable)

Add to FFmpeg command (already in code):

-hwaccel videotoolbox
-hwaccel_output_format videotoolbox

Problem: FFmpeg still errors out instead of gracefully falling back.

Option 3: Separate Channels by Codec

Create two channels:

  • Channel 80: Seasons 2-8 (MP4/H.264) with hwaccel: videotoolbox
  • Channel 81: Season 1 (AVI/MPEG-4) with hwaccel: null

This works but is inconvenient.

Recommended Configuration

For Mixed Codec Collections (Like Magnum P.I.)

Disable hardware acceleration:

ffmpeg:
  hwaccel: null
  threads: 0  # Auto-detect CPU threads

Performance: Software decoding on modern Macs (M1/M2/M3) is fast enough for real-time transcoding.

For H.264-Only Collections

If you have a collection with only modern H.264 MP4 files, enable hardware acceleration:

ffmpeg:
  hwaccel: videotoolbox
  hwaccel_device: null

Performance Comparison

With VideoToolbox (H.264 only)

  • ✅ Lower CPU usage (~20-30%)
  • ✅ Lower power consumption
  • ✅ Better battery life (laptops)
  • ❌ FAILS on MPEG-4/DivX/XviD

Without Hardware Acceleration (All Codecs)

  • ✅ Works with ALL codecs
  • ✅ Reliable for mixed collections
  • ✅ No codec-specific errors
  • ⚠️ Higher CPU usage (~50-70%)
  • ⚠️ More power consumption

M1/M2/M3 Mac Performance (Software Decoding)

Modern Apple Silicon is fast enough for software decoding:

  • M1: Can handle 4-6 simultaneous transcodes
  • M2/M3: Can handle 6-10+ simultaneous transcodes
  • Efficiency: CPU cores handle transcoding efficiently

For most users: Software decoding is perfectly fine! ✅

Testing

Verify the Fix

  1. Restart StreamTV server:

    ./start_server.sh

  2. Try streaming Season 1 (AVI files):

    curl -I http://localhost:8410/iptv/stream/80

  3. Check logs for errors:

    tail -f ~/Library/Logs/StreamTV/streamtv-*.log | grep -i "ffmpeg\|error"

Expected Results

✅ No "hwaccel initialisation" errors
✅ Streams play successfully
✅ Both AVI and MP4 files work
✅ Slight CPU increase (acceptable)

CPU Monitoring

Watch CPU usage while streaming:

# Monitor CPU usage
top -pid $(pgrep -f ffmpeg) -stats cpu

On M1/M2/M3 Macs, expect:

  • 1 stream: 30-50% CPU (one core)
  • 2 streams: 50-80% CPU
  • 3+ streams: May approach 100% but still playable

Future Improvements

Per-Video Codec Detection (Future Enhancement)

Ideal solution would be:

  1. Detect video codec before transcoding
  2. Enable hardware acceleration for H.264/HEVC
  3. Use software decoding for MPEG-4/DivX
  4. Automatic per-video decision

PATH INDEPENDENCE

Path Independence - Installation Scripts

Overview

All StreamTV installation scripts are designed to work from any location on your system. You can:

  • Move the installer to any folder
  • Run it from a USB drive
  • Run it from a network location
  • Create shortcuts anywhere

How It Works

macOS Scripts

install_gui.py:

  • Uses __file__ and Path.resolve() to get absolute script path
  • Handles symlinks correctly with resolve()
  • Changes working directory to script location
  • Sets PYTHONPATH to ensure imports work
  • All file references use absolute paths

install-gui.sh:

  • Uses readlink -f to resolve symlinks (with fallback for macOS)
  • Gets absolute script directory
  • Changes to script directory before execution
  • Works from any location

Install-StreamTV.command:

  • Uses proper path resolution for macOS
  • Handles both GUI and terminal environments
  • Works when double-clicked from Finder

Testing Path Independence

macOS

  1. Copy installer to different location:

    cp install_gui.py /tmp/test/
cd /tmp/test
python3 install_gui.py

  2. Create symlink:

    ln -s /path/to/StreamTV/install_gui.py ~/Desktop/install
cd ~/Desktop
python3 install

  3. Run from USB drive:

    /Volumes/USB/StreamTV/install-gui.sh

  4. Double-click from anywhere:

    • Move Install-StreamTV.command to Desktop
    • Double-click it
    • Works perfectly!

Key Features

Absolute Path Resolution

All scripts:

  • ✅ Detect their own location automatically
  • ✅ Resolve to absolute paths
  • ✅ Handle symlinks correctly
  • ✅ Work from any current directory

Working Directory Management

Scripts:

  • ✅ Change to script directory before execution
  • ✅ Ensure relative imports work
  • ✅ Set PYTHONPATH when needed
  • ✅ Use absolute paths for all file operations

Error Handling

If path resolution fails:

  • ✅ Scripts show clear error messages
  • ✅ Suggest checking file locations
  • ✅ Provide troubleshooting steps

Benefits

  1. User-Friendly: Users can place installer anywhere
  2. Flexible: Works from USB drives, network shares, etc.
  3. Reliable: No dependency on current working directory
  4. Portable: Easy to distribute and share

Troubleshooting

"File not found" errors

If you see file not found errors:

  1. Make sure all StreamTV files are in the same directory
  2. Don't move individual files - move the entire folder
  3. Check that the installer script is in the StreamTV root directory

Import errors (Python)

If you see Python import errors:

  1. Make sure you're running from the StreamTV directory
  2. Check that streamtv package is in the same directory
  3. Verify PYTHONPATH is set correctly (handled automatically)

Path resolution issues

If path resolution fails:

  1. Check file permissions
  2. Verify script is not corrupted
  3. Try running from the StreamTV directory directly
  4. Check if symlinks are broken: readlink -f install_gui.py (Linux) or readlink install_gui.py (macOS)

Command file not working

If Install-StreamTV.command doesn't work:

  1. Make sure it's executable: chmod +x Install-StreamTV.command
  2. Right-click → Get Info → Check "Open with" is set to Terminal
  3. Try running from Terminal: ./Install-StreamTV.command

SCHEDULE BREAKS FIX

Schedule Breaks Collection Fix

Issue

Warning in logs:

WARNING - Collection/Playlist not found: Inter-Episode Breaks

Root Cause

The generated schedule file referenced a collection "Inter-Episode Breaks" for the 2-5 minute breaks between episodes, but this collection was never created in the database.

The schedule had entries like:

- all: break_short
  custom_title: "Inter-Episode Break"
  duration: PT3M

But break_short pointed to a non-existent collection.

Fix Applied

Option 1: Remove Breaks (Applied) ✅

Removed all break entries from the schedule file. Episodes now play back-to-back without breaks.

Before: 1,845 lines (with 296 breaks)
After: 663 lines (episodes only)

Result: Clean continuous playback

Option 2: Create Filler Collection (Alternative)

If you want breaks, you would need to:

  1. Create actual filler content (black screen video, station IDs, etc.)
  2. Import as a collection called "Inter-Episode Breaks"
  3. Keep the break entries in the schedule

Current Schedule Structure

name: Magnum P.I. Marathon
description: 24/7 marathon of Magnum P.I. episodes

content:
  - key: season1
    collection: Magnum P.I. - Season 1
    order: chronological
  # ... seasons 2-8 ...

sequence:
  - key: magnum-marathon
    items:
      - all: season1
        custom_title: "Season 1 Episode 1"
      - all: season1
        custom_title: "Season 1 Episode 2"
      # ... continues ...

playout:
  - sequence: magnum-marathon
  - repeat: true

Result: Episodes play continuously without breaks

Adding Breaks in the Future

If you want to add breaks later, you have two options:

Option 1: Create Filler Media

  1. Create filler videos (2-5 minutes each):

    • Black screen with logo
    • Station IDs
    • "We'll be right back" cards
    • Vintage commercials

  2. Import as collection:

    # In channels.yaml
streams:
  - id: filler_01
    collection: "Inter-Episode Breaks"
    type: filler
    url: "path/to/filler1.mp4"
    runtime: PT2M
  - id: filler_02
    collection: "Inter-Episode Breaks"
    type: filler
    url: "path/to/filler2.mp4"
    runtime: PT3M

  3. Update schedule to reference the collection

Option 2: Use Existing Content

Reuse content from other collections as breaks:

content:
  - key: station_ids
    collection: WCCO Station IDs  # Use existing content
    order: random

sequence:
  - all: season1
  - all: station_ids  # Use as break
    count: 1
  - all: season1

Comparison with Olympic Channels

Olympic Channels

  • No breaks in schedules
  • Continuous playback
  • Events flow directly into each other

Magnum P.I. (Current)

  • No breaks (like Olympics)
  • Continuous episode playback
  • Episodes flow directly into each other

Magnum P.I. (With Breaks - Future)

  • Would need filler collection
  • 2-5 minute breaks between episodes
  • More like traditional TV

Performance Impact

Without Breaks (Current)

  • ✅ Simpler schedule (663 lines vs 1,845)
  • ✅ Faster parsing
  • ✅ No collection lookup overhead
  • ✅ Continuous playback

With Breaks (If Added)

  • More complex schedule
  • Requires filler media collection
  • More realistic TV experience
  • Slightly more processing

Recommendation

For now: Keep it simple without breaks

  • Episodes play continuously
  • No warnings in logs
  • Simpler to maintain

Later: Add breaks if desired

  • Create filler content
  • Import as collection
  • Update schedule to reference it

Verification

Check Schedule Parses

python3 -c "
from pathlib import Path
from streamtv.scheduling.parser import ScheduleParser
schedule = ScheduleParser.parse_file(Path('schedules/80.yml'))
print(f'Schedule: {schedule.name}')
print(f'Items: {len(schedule.content_map)}')
"

Check No Warnings

./scripts/view-logs.sh search "Inter-Episode Breaks"

Should show no new warnings after restart.

Summary

Issue: Referenced non-existent "Inter-Episode Breaks" collection
Fix: Removed break entries from schedule
Result: Clean continuous playback

SCHEDULE FILE NAMING

Schedule File Naming Convention

Issue

Channel 80 (Magnum P.I.) showed "No schedule" in the Playout page.

Root Cause

The schedule parser looks for specific filename patterns based on channel number:

# From streamtv/scheduling/parser.py
possible_names = [
    f"mn-olympics-{channel_number}.yml",   # e.g., mn-olympics-80.yml
    f"mn-olympics-{channel_number}.yaml",  # e.g., mn-olympics-80.yaml
    f"{channel_number}.yml",               # e.g., 80.yml ✅
    f"{channel_number}.yaml"               # e.g., 80.yaml
]

Problem: We named the file magnum-pi-schedule.yml
Solution: Must be named 80.yml to match the channel number

Fix Applied

Renamed schedule file:

# Created proper name
cp schedules/magnum-pi-schedule.yml schedules/80.yml

Result: ✅ Schedule now found and parsed!

✅ Schedule file found: schedules/80.yml
✅ Schedule parsed: Magnum P.I. Marathon
   Content items: 10
   Sequences: 1
   Playout instructions: 2

Naming Rules for Schedule Files

Channel Number-Based (Required)

For the parser to automatically find schedule files, use:

schedules/{channel_number}.yml

Examples:

  • Channel 1980 → schedules/1980.yml or schedules/mn-olympics-1980.yml
  • Channel 1984 → schedules/1984.yml or schedules/mn-olympics-1984.yml
  • Channel 80 → schedules/80.yml ✅
  • Channel 100 → schedules/100.yml

Legacy Pattern (Also Supported)

For Olympic channels, the legacy pattern works:

schedules/mn-olympics-{channel_number}.yml

Examples:

  • schedules/mn-olympics-1980.yml
  • schedules/mn-olympics-1984.yml

Current Schedule Files

schedules/
├── mn-olympics-1980.yml    ✅ Found (Channel 1980)
├── mn-olympics-1984.yml    ✅ Found (Channel 1984)
├── mn-olympics-1988.yml    ✅ Found (Channel 1988)
├── mn-olympics-1992.yml    ✅ Found (Channel 1992)
├── mn-olympics-1994.yml    ✅ Found (Channel 1994)
├── 80.yml                  ✅ Found (Channel 80) ⭐
└── magnum-pi-schedule.yml  ⚠️ Not auto-discovered (wrong name)

Best Practices

For New Channels

Always name schedule files by channel number:

# Good - auto-discovered
schedules/80.yml
schedules/100.yml
schedules/200.yml

# Bad - not auto-discovered
schedules/magnum-pi-schedule.yml
schedules/my-channel.yml
schedules/awesome-content.yml

For Descriptive Names

If you want descriptive filenames, create a symbolic link:

# Create the required numeric name
cp my-schedule.yml 80.yml

# Keep descriptive name too (optional)
ln -s 80.yml magnum-pi-schedule.yml

How Schedule Discovery Works

1. Channel Management

When displaying channels in the UI, the system calls:

schedule_file = ScheduleParser.find_schedule_file(channel.number)

2. File Search

The parser searches for files in this order:

  1. mn-olympics-{channel_number}.yml
  2. mn-olympics-{channel_number}.yaml
  3. {channel_number}.yml ✅ (Most common)
  4. {channel_number}.yaml

3. Result

  • If found: Schedule is loaded and used for playout
  • If not found: Shows "No schedule" in UI

After Fix

Restart Server Required

For the schedule to show in the Playout page:

# Restart StreamTV
./start_server.sh

Expected Result

In the Playout page for Channel 80:

  • ✅ Schedule name: "Magnum P.I. Marathon"
  • ✅ Green indicator instead of grey
  • ✅ Shows schedule details
  • ✅ Can view/edit playout

Verification

Check Schedule is Found

python3 -c "
from streamtv.scheduling.parser import ScheduleParser
schedule = ScheduleParser.find_schedule_file('80')
print(f'Schedule for Channel 80: {schedule}')
"

Expected: schedules/80.yml

Test Schedule Parsing

python3 -c "
from pathlib import Path
from streamtv.scheduling.parser import ScheduleParser

file = Path('schedules/80.yml')
schedule = ScheduleParser.parse_file(file)
print(f'Name: {schedule.name}')
print(f'Content items: {len(schedule.content_map)}')
print(f'Sequences: {len(schedule.sequences)}')
"

Expected: Should parse without errors

SECURITY AUDIT REPORT

Security Audit Report - StreamTV

Date: 2025-01-27
Auditor: AI Security Analysis
Reference Guide: Palo Alto Networks Application Security Guide

Executive Summary

This security audit was conducted to verify the security posture of the StreamTV application according to application security best practices. The audit identified 1 CRITICAL, 2 HIGH, 4 MEDIUM, and 3 LOW severity security issues that require attention.

Risk Summary

  • CRITICAL: 1 issue
  • HIGH: 2 issues
  • MEDIUM: 4 issues
  • LOW: 3 issues

CRITICAL Issues

1. Plaintext Credentials in Configuration File ⚠️ CRITICAL

Location: config.yaml (lines 22-23)

Issue:

archive_org:
  username: roto31
  password: Airforc1

Plaintext credentials are stored in the configuration file, which poses a severe security risk if the file is:

  • Committed to version control
  • Accessed by unauthorized users
  • Exposed through file system permissions
  • Logged or backed up

Impact:

  • Complete compromise of Archive.org account
  • Potential access to user's personal data
  • Violation of security best practices

Recommendation:

  1. IMMEDIATE ACTION: Remove credentials from config.yaml immediately
  2. Use macOS Keychain for credential storage (already implemented but not being used)
  3. Ensure config.yaml is in .gitignore (✅ Already configured)
  4. Set proper file permissions: chmod 600 config.yaml
  5. For non-macOS platforms, use encrypted configuration or environment variables

Code Reference:

  • streamtv/utils/macos_credentials.py - Keychain storage is available
  • streamtv/api/auth.py - Credentials should be stored in Keychain on macOS

HIGH Severity Issues

2. Overly Permissive CORS Configuration ⚠️ HIGH

Location: streamtv/main.py (lines 93-99)

Issue:

app.add_middleware(
    CORSMiddleware,
    allow_origins=["*"],  # ⚠️ Allows all origins
    allow_credentials=True,
    allow_methods=["*"],
    allow_headers=["*"],
)

Impact:

  • Any website can make requests to the API
  • Enables Cross-Site Request Forgery (CSRF) attacks
  • Allows unauthorized access from malicious websites
  • Combined with allow_credentials=True, this is particularly dangerous

Recommendation:

  1. Restrict allow_origins to specific trusted domains
  2. Remove wildcard (*) when allow_credentials=True
  3. Use environment-based configuration: 
    allowed_origins = os.getenv("CORS_ORIGINS", "http://localhost:8410").split(",")
app.add_middleware(
    CORSMiddleware,
    allow_origins=allowed_origins,
    allow_credentials=True,
    allow_methods=["GET", "POST", "PUT", "DELETE"],
    allow_headers=["Content-Type", "Authorization"],
)

3. Optional API Key Authentication ⚠️ HIGH

Location: config.yaml (line 25)

Issue:

security:
  api_key_required: false  # ⚠️ Authentication disabled by default
  access_token: null

Impact:

  • API endpoints are publicly accessible without authentication
  • No protection against unauthorized access
  • Sensitive operations (channel management, media import) are unprotected

Recommendation:

  1. Enable API key authentication by default in production
  2. Require authentication for all write operations (POST, PUT, DELETE)
  3. Implement role-based access control (RBAC) if needed
  4. Add authentication middleware to protect sensitive endpoints

Code Reference:

  • Authentication check should be implemented in streamtv/api/ endpoints
  • See .github/wiki/Authentication-System.md for implementation details

MEDIUM Severity Issues

4. Information Disclosure in Error Messages ⚠️ MEDIUM

Location: Multiple files in streamtv/api/

Issue: Error messages expose internal details:

raise HTTPException(status_code=500, detail=str(e))  # Exposes full exception

Examples Found:

  • streamtv/api/auth.py:109 - detail=str(e)
  • streamtv/api/auth.py:198 - detail=str(e)
  • streamtv/api/import_api.py:69 - detail=f"Error importing channels: {str(e)}"

Impact:

  • Reveals internal system structure
  • May expose file paths, database structure, or implementation details
  • Aids attackers in crafting targeted attacks

Recommendation:

  1. Use generic error messages in production: 
    logger.error(f"Error: {e}", exc_info=True)  # Log full details
raise HTTPException(status_code=500, detail="An internal error occurred")
  2. Only show detailed errors in development/debug mode
  3. Sanitize error messages before returning to clients

5. Insufficient File Upload Validation ⚠️ MEDIUM

Location: streamtv/api/auth.py:157-198, streamtv/api/import_api.py:20-75

Issue: File uploads have minimal validation:

  • Only checks file extension (.yaml, .yml)
  • Basic content validation for cookies file
  • No file size limits
  • No MIME type verification
  • No virus/malware scanning

Impact:

  • Potential for malicious file uploads
  • DoS attacks through large file uploads
  • Path traversal vulnerabilities if file paths are used unsafely

Recommendation:

  1. Implement file size limits: 
    MAX_FILE_SIZE = 10 * 1024 * 1024  # 10MB
if file.size > MAX_FILE_SIZE:
    raise HTTPException(400, "File too large")
  2. Verify MIME types, not just extensions
  3. Sanitize file names to prevent path traversal
  4. Store uploaded files outside web root
  5. Scan files for malicious content if possible

6. No Rate Limiting ⚠️ MEDIUM

Location: Application-wide

Issue: No rate limiting implemented on API endpoints, allowing:

  • Brute force attacks on authentication endpoints
  • DoS attacks through excessive requests
  • Resource exhaustion

Impact:

  • Account enumeration
  • Brute force credential attacks
  • Service unavailability

Recommendation:

  1. Implement rate limiting middleware: 
    from slowapi import Limiter, _rate_limit_exceeded_handler

SECURITY FIXES IMPLEMENTED

Security Fixes Implementation Summary

Date: 2025-01-27
Status: ✅ All Critical and High Priority Fixes Implemented

Implemented Security Fixes

1. ✅ Removed Plaintext Credentials from config.yaml

Changes Made:

  • Removed plaintext password from config.yaml (set to null)
  • Updated streamtv/api/auth.py to store credentials in macOS Keychain instead of config file
  • Modified streamtv/streaming/stream_manager.py to load credentials from Keychain first, then fall back to config
  • Updated authentication endpoint to never store passwords in config.yaml

Files Modified:

  • config.yaml - Removed password, set to null
  • streamtv/api/auth.py - Updated to use Keychain for password storage
  • streamtv/streaming/stream_manager.py - Added Keychain credential loading

Security Impact:

  • Passwords are now stored securely in macOS Keychain
  • No credentials in plaintext configuration files
  • Credentials are loaded from Keychain at runtime

2. ✅ Restricted CORS to Specific Origins

Changes Made:

  • Updated streamtv/main.py to restrict CORS origins
  • Added support for CORS_ORIGINS environment variable
  • Default origins limited to localhost and configured base_url
  • Removed wildcard (*) origin support
  • Restricted allowed methods and headers

Configuration:

# Default origins (if CORS_ORIGINS env var not set):
- http://localhost:8410
- http://127.0.0.1:8410
- {config.server.base_url}

# Set CORS_ORIGINS environment variable for custom origins:
export CORS_ORIGINS="https://example.com,https://app.example.com"

Files Modified:

  • streamtv/main.py - Updated CORS middleware configuration

Security Impact:

  • Prevents unauthorized cross-origin requests
  • Reduces CSRF attack surface
  • Configurable via environment variable for production

3. ✅ Enabled API Key Authentication by Default

Changes Made:

  • Updated streamtv/config.py to set api_key_required: True by default
  • Updated config.yaml to reflect new default
  • Updated config.example.yaml documentation

Files Modified:

  • streamtv/config.py - Changed default api_key_required to True
  • config.yaml - Set api_key_required: true

Security Impact:

  • API endpoints now require authentication by default
  • Prevents unauthorized access to API
  • Users must explicitly configure access tokens

Note: Users need to generate and set an access token:

python3 -c "import secrets; print(secrets.token_urlsafe(32))"

Then add to config.yaml:

security:
  api_key_required: true
  access_token: "your-generated-token-here"

4. ✅ Implemented Rate Limiting on Authentication Endpoints

Changes Made:

  • Added slowapi==0.1.9 to requirements.txt
  • Initialized rate limiter in streamtv/main.py
  • Created rate limiting decorator in streamtv/api/auth.py
  • Applied rate limits to all authentication endpoints:
    • Archive.org login: 5 requests/minute
    • YouTube cookies upload: 10 requests/hour
    • OAuth endpoints: 10 requests/minute
    • Passkey endpoints: 5 requests/minute

Rate Limits Applied:

Endpoint Rate Limit
POST /api/auth/archive-org 5/minute
POST /api/auth/youtube/cookies 10/hour
GET /api/auth/youtube/oauth 10/minute
POST /api/auth/youtube/oauth/passkey/* 5/minute
GET /api/auth/youtube/oauth/callback 10/minute

Files Modified:

  • requirements.txt - Added slowapi dependency
  • streamtv/main.py - Initialized rate limiter
  • streamtv/api/auth.py - Added rate limiting to all auth endpoints

Security Impact:

  • Prevents brute force attacks on authentication endpoints
  • Reduces risk of credential enumeration
  • Protects against DoS attacks on auth endpoints

Installation Instructions

1. Install New Dependencies

pip install -r requirements.txt

This will install slowapi==0.1.9 for rate limiting.

2. Configure CORS (Optional)

For production, set the CORS_ORIGINS environment variable:

export CORS_ORIGINS="https://yourdomain.com,https://app.yourdomain.com"

3. Generate and Set API Access Token

Since API key authentication is now enabled by default, generate a secure token:

python3 -c "import secrets; print(secrets.token_urlsafe(32))"

Add the generated token to config.yaml:

security:
  api_key_required: true
  access_token: "your-generated-token-here"

4. Re-authenticate Archive.org (if needed)

If you had credentials in config.yaml, you'll need to re-authenticate:

  1. Go to /api/auth/archive-org in your browser
  2. Enter your credentials
  3. Credentials will be stored in macOS Keychain (secure)

Testing the Fixes

Test Rate Limiting

Try making multiple rapid requests to an auth endpoint:

# This should fail after 5 requests in a minute
for i in {1..10}; do
  curl -X POST http://localhost:8410/api/auth/archive-org \
    -H "Content-Type: application/json" \
    -d '{"username":"test","password":"test"}'
  echo ""
done

You should see rate limit errors after the 5th request.

Test CORS

Try accessing from an unauthorized origin - it should be blocked.

Test API Key Authentication

Try accessing an API endpoint without a token - it should be rejected.

Migration Notes

For Existing Installations

  1. Credentials Migration:
    • If you had credentials in config.yaml, they've been removed
    • Re-authenticate via the web interface to store in Keychain
    • The username will remain in config.yaml (for reference only)
