🚀 Quick Start

Build & Run

cd apps/rtmp-server
make build
./rtmp-server

Publish a Stream

# Using FFmpeg
ffmpeg -re -i video.mp4 -c:v libx264 -preset ultrafast -c:a aac \
  -f flv rtmp://localhost:1935/live/mystream

# Test pattern with audio
ffmpeg -re -f lavfi -i testsrc=size=1280x720:rate=30 \
  -f lavfi -i sine=frequency=440 \
  -c:v libx264 -preset ultrafast -c:a aac \
  -f flv rtmp://localhost:1935/live/test

Play a Stream

# FFplay
ffplay rtmp://localhost:1935/live/mystream

# VLC
vlc rtmp://localhost:1935/live/mystream
