Addressed 5 HIGH priority issues identified in code review: HIGH #12: safe_alsa_open validation (audio.c:314-327) - Added validation for snd_pcm_nonblock() return value - Properly close handle and return error if blocking mode fails - Prevents silent failures when switching to blocking mode HIGH #13: WebRTC write failure handling (relay.go:74-147) - Track consecutive WebRTC write failures in OutputRelay - Reconnect source after 50 consecutive failures - Throttle warning logs (first failure + every 10th) - Prevents silent audio degradation from persistent write errors HIGH #14: Opus packet size validation (audio.c:1024-1027) - Moved validation before mutex acquisition - Reduces unnecessary lock contention for invalid packets - Validates opus_buf, opus_size bounds before hot path HIGH #15: FEC recovery validation (audio.c:1050-1071) - Added detailed logging for FEC usage - Log warnings when decode fails and FEC is attempted - Log info/error messages for FEC success/failure - Log warning when FEC returns 0 frames (silence) - Improves debuggability of packet loss scenarios Comment accuracy fixes (audio.c:63-67, 149-150, 164-165) - Clarified RFC 7587 comment: RTP clock rate vs codec sample rate - Explained why sr/fs parameters are ignored - Added context about SpeexDSP resampling Channel map validation (audio.c:572-579) - Added validation for unexpected channel counts - Check for SND_CHMAP_UNKNOWN positions - Prevents crashes from malformed channel map data |

JetKVM is a high-performance, open-source KVM over IP (Keyboard, Video, Mouse) solution designed for efficient remote management of computers, servers, and workstations. Whether you're dealing with boot failures, installing a new operating system, adjusting BIOS settings, or simply taking control of a machine from afar, JetKVM provides the tools to get it done effectively.
Features
- Ultra-low Latency - 1080p@60FPS video with 30-60ms latency using H.264 encoding. Smooth mouse and keyboard interaction for responsive remote control.
- Free & Optional Remote Access - Remote management via JetKVM Cloud using WebRTC.
- Open-source software - Written in Golang on Linux. Easily customizable through SSH access to the JetKVM device.
Contributing
We welcome contributions from the community! Whether it's improving the firmware, adding new features, or enhancing documentation, your input is valuable. We also have some rules and taboos here, so please read this page and our Code of Conduct carefully.
I need help
The best place to search for answers is our Documentation. If you can't find the answer there, check our Discord Server.
I want to report an issue
If you've found an issue and want to report it, please check our Issues page. Make sure the description contains information about the firmware version you're using, your platform, and a clear explanation of the steps to reproduce the issue.
Development
JetKVM is written in Go & TypeScript. with some bits and pieces written in C. An intermediate level of Go & TypeScript knowledge is recommended for comfortable programming.
The project contains two main parts, the backend software that runs on the KVM device and the frontend software that is served by the KVM device, and also the cloud.
For comprehensive development information, including setup, testing, debugging, and contribution guidelines, see DEVELOPMENT.md.
For quick device development, use the ./dev_deploy.sh script. It will build the frontend and backend and deploy them to the local KVM device. Run ./dev_deploy.sh --help for more information.
Backend
The backend is written in Go and is responsible for the KVM device management, the cloud API and the cloud web.
Frontend
The frontend is written in React and TypeScript and is served by the KVM device. It has three build targets: device, development and production. Development is used for development of the cloud version on your local machine, device is used for building the frontend for the KVM device and production is used for building the frontend for the cloud.
