## Features
|
||||
|
||||
### Core Streaming
|
||||
- 🚀 **Pure HTTP Proxy**: Zero transcoding, direct byte-for-byte streaming
|
||||
- 🔗 **Connection Sharing**: Multiple viewers share one upstream provider connection (HLS, Transcoded, and live Direct/TS streams)
|
||||
- ⚡️ **Truly Ephemeral**: Provider connections open only when clients are consuming; close when the last client disconnects
|
||||
- 📺 **HLS Support**: Optimized playlist and segment handling (.m3u8)
|
||||
- 📡 **Continuous Streams**: Primary/subscriber broadcast for .ts, .mp4, .mkv, .webm, .avi live streams
|
||||
- 🔄 **Real-time URL Rewriting**: Automatic playlist modification for proxied content
|
||||
- 📱 **Full VOD Support**: Per-client connections with byte-range requests and seeking
|
||||
- 🎬 **Strict Live TS Mode**: Enhanced stability for live MPEG-TS with pre-buffering & circuit breaker
|
||||
|
||||
### Performance & Reliability
|
||||
- ⚡ **uvloop Integration**: 2-4x faster async I/O operations
|
||||
- 🔄 **Seamless Failover**: <100ms transparent URL switching per client
|
||||
- 🎯 **Immediate Cleanup**: Connections close instantly when client stops
|
||||
|
||||
### Transcoding Available with Hardware Acceleration
|
||||
- 🎬 **FFmpeg Integration**: Built-in hardware-accelerated video processing
|
||||
- 🚀 **GPU Acceleration**: Automatic detection of NVIDIA, Intel, and AMD GPUs
|
||||
- ⚡ **VAAPI Support**: Intel/AMD hardware encoding (3-8x faster than CPU)
|
||||
- 🎯 **NVENC Support**: NVIDIA hardware encoding (10-20x faster than CPU)
|
||||
- 🔧 **Auto-Configuration**: Zero-config hardware acceleration setup
|
||||
- 📊 **Multiple Codecs**: H.264, H.265/HEVC, VP8, VP9, AV1 support
|
||||
|
||||
### Management & Monitoring
|
||||
- 👥 **Client Tracking**: Individual client sessions and bandwidth monitoring
|
||||
- 📊 **Real-time Statistics**: Live metrics on streams, clients, and data usage
|
||||
- 🔎 **Stream Type Detection**: Automatic HLS/VOD/Live detection
|
||||
- 🧹 **Automatic Cleanup**: Inactive streams and clients auto-removed
|
||||
- 📣 **Event System**: Real-time events and webhook notifications

|
||||
## Configuration
|
||||
|
||||
### Environment Variables
|
||||
|
||||
```bash
|
||||
# Server configuration
|
||||
M3U_PROXY_HOST=0.0.0.0
|
||||
M3U_PROXY_PORT=8085
|
||||
|
||||
# Base path for API routes (useful for reverse proxy integration)
|
||||
# Default: /m3u-proxy (optimized for m3u-editor integration)
|
||||
# Set to empty string for root path
|
||||
ROOT_PATH=/m3u-proxy
|
||||
|
||||
# API Authentication (optional)
|
||||
# Set API_TOKEN to require authentication for management endpoints
|
||||
# Leave unset or empty to disable authentication
|
||||
API_TOKEN=your_secret_token_here
|
||||
|
||||
# Client timeout (seconds)
|
||||
CLIENT_TIMEOUT=300
|
||||
|
||||
# Cleanup interval (seconds)
|
||||
CLEANUP_INTERVAL=60
|
||||
|
||||
# Stream Retry Configuration (improves reliability for unstable connections)
|
||||
# Number of retry attempts before failover or giving up
|
||||
STREAM_RETRY_ATTEMPTS=3
|
||||
# Delay between retries (seconds)
|
||||
STREAM_RETRY_DELAY=1.0
|
||||
# Total timeout across all retries (seconds, 0 to disable)
|
||||
STREAM_TOTAL_TIMEOUT=60.0
|
||||
# Use exponential backoff for retry delays (false/true)
|
||||
STREAM_RETRY_EXPONENTIAL_BACKOFF=false
|
||||
# Timeout for receiving data chunks (seconds)
|
||||
LIVE_CHUNK_TIMEOUT_SECONDS=15.0
|
||||
|
||||
# Sticky Session Handler (prevents playback loops with load-balanced providers)
|
||||
# Locks to specific backend after redirect to maintain playlist consistency
|
||||
USE_STICKY_SESSION=false
|
||||
```
|
||||
|
||||
### API Authentication
|
||||
|
||||
When `API_TOKEN` is set in the environment, all management endpoints require authentication via the `X-API-Token` header. This includes:
|
||||
|
||||
- `/` - Root endpoint
|
||||
- `/streams` - Create, list, get, delete streams
|
||||
- `/stats/*` - All statistics endpoints
|
||||
- `/clients` - Client management
|
||||
- `/health` - Health check endpoint
|
||||
- `/webhooks` - Webhook management
|
||||
- `/streams/{stream_id}/failover` - Failover control
|
||||
- `/hls/{stream_id}/clients/{client_id}` - Client disconnect
|
||||
|
||||
**Stream endpoints (the actual streaming URLs) do NOT require authentication** since they are accessed by media players that identify streams via `stream_id`.
|
||||
|
||||
Example with authentication:
|
||||
|
||||
```bash
|
||||
# Set your API token
|
||||
export API_TOKEN="my_secret_token"
|
||||
|
||||
# Method 1: Using header (recommended for API calls)
|
||||
curl -X POST "http://localhost:8085/streams" \
|
||||
-H "Content-Type: application/json" \
|
||||
-H "X-API-Token: my_secret_token" \
|
||||
-d '{"url": "https://your-stream.m3u8"}'
|
||||
|
||||
# Method 2: Using query parameter (useful for browser access)
|
||||
curl -X POST "http://localhost:8085/streams?api_token=my_secret_token" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"url": "https://your-stream.m3u8"}'
|
||||
|
||||
# Browser access example
|
||||
# Visit: http://localhost:8085/stats?api_token=my_secret_token
|
||||
|
||||
# Without token - will get 401 error
|
||||
curl -X POST "http://localhost:8085/streams" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"url": "https://your-stream.m3u8"}'
|
||||
```
|
||||
|
||||
To disable authentication, simply leave `API_TOKEN` unset or set it to an empty string.
|
||||
|
||||

|
||||
```
|
||||
|
||||
### Programming Interface
|
||||
|
||||
The hardware acceleration is available through Python APIs:
|
||||
|
||||
```python
|
||||
from hwaccel import get_ffmpeg_hwaccel_args, is_hwaccel_available
|
||||
|
||||
# Check if hardware acceleration is available
|
||||
if is_hwaccel_available():
|
||||
# Get optimized FFmpeg arguments
|
||||
hwaccel_args = get_ffmpeg_hwaccel_args("h264")
|
||||
|
||||
# Example: Hardware-accelerated transcoding
|
||||
cmd = ["ffmpeg"] + hwaccel_args + [
|
||||
"-i", "input_stream.m3u8",
|
||||
"-c:v", "h264_vaapi", # Hardware encoder
|
||||
"-preset", "fast",
|
||||
"-b:v", "2M",
|
||||
"output_stream.mp4"
|
||||
]
|
||||
```
|
||||
|
||||

```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
1. **Stream Won't Load**
|
||||
- Check original URL accessibility
|
||||
- Verify CORS headers if accessing from browser
|
||||
- Check server logs for detailed errors
|
||||
|
||||
2. **High Memory Usage**
|
||||
- Reduce `CLIENT_TIMEOUT` for faster cleanup
|
||||
- Monitor client connections and cleanup inactive ones
|
||||
- Consider horizontal scaling for high loads
|
||||
|
||||
3. **Failover Not Working**
|
||||
- Verify failover URLs are accessible
|
||||
- Check failover trigger conditions in logs
|
||||
- Test manual failover via API
|
||||
|
||||
### Debug Mode
|
||||
|
||||
```bash
|
||||
# Enable detailed logging
|
||||
export LOG_LEVEL=DEBUG
|
||||
python main.py --debug
|
||||
```
|
||||
|
||||
