Preventing Frame Drops & Packet Loss in Wireless RTMP Video Transmission

By CastZero Core Engineering · Published July 20, 2026

Diagnosing Wireless Transmission Stutter

Frame drops during live video streaming are caused by network packet loss, wireless interference, or CPU/GPU decoding bottlenecks. CastZero provides real-time packet loss indicators in the application header.

Step-by-Step Fixes for Smooth 60fps Video

  • Switch to 80MHz Channel Width: In your 5GHz router settings, set channel width to 80MHz or 160MHz for maximum throughput.
  • Cap Bitrate to 8Mbps: Avoid exceeding 12Mbps per camera feed on shared Wi-Fi networks.
  • Use WebRTC UDP Instead of TCP Media Source: WebRTC drops late frames gracefully rather than freezing the video stream.
