The Engineering Behind Local C++ Media Ingestion
High-throughput live video ingestion requires extreme memory efficiency and non-blocking I/O routines. Traditional Node.js or Python streaming wrappers introduce GC overhead and thread lock contention, causing jitter in 60fps feeds.
CastZero Engine uses an optimized native C++ MediaMTX daemon compiled specifically for Windows x64. Incoming RTMP TCP sockets are processed via zero-copy buffer pools and remuxed directly into WebRTC UDP packets.

Key Performance Metrics
- Memory Footprint: Under 45MB RAM during active 4K60 ingestion.
- CPU Overhead: < 2.5% CPU utilization on Intel Core i7 / AMD Ryzen 7 processors.
- Port Allocation: Port 1935 (TCP Ingest), Port 8889 (HTTP API), Port 8189 (WebRTC UDP).
