Waybeam venc — Video encoder for FPV
waybeam venc is a standalone H.265/H.264 video encoder and RTP streamer for cameras on SigmaStar Infinity6E (Star6E) and Infinity6C (Maruko) chips. It was designed specifically for FPV drones with minimal latency and full real-time control via an HTTP API.

| EIS (stabilization) | GyroGlide-Lite — gyroscopic stabilization (Star6E only) |
| IMU | BMI270 support (Star6E only) |
Supported chips
| Chip | Name | Status |
|---|---|---|
| SigmaStar Infinity6E | Star6E (SSC338Q etc.) | ✅ Full support |
| SigmaStar Infinity6C | Maruko | ✅ Full support |
Star6E and RTP
On Star6E the outgoing.streamMode: "rtp" mode requires the codec video0.codec: "h265". Maruko supports both codecs: h264 and h265.
