    questdb

    17.4Kquestdb/questdb · Java

    QuestDB is an open-source, low-latency time-series database on open formats: it ingests millions of events per second, computes on live data in milliseconds, and keeps years of history queryable through one SQL engine.

  5. 8

    hls.js

    17Kvideo-dev/hls.js · TypeScript

    A JavaScript library that plays HLS (HTTP Live Streaming) video directly in the browser. It relies on HTML5 video and Media Source Extensions, transmuxing MPEG-2 TS and AAC/MP3 streams into MP4 fragments asynchronously in a Web Worker.

  6. 9

    kcp

    16.9Kskywind3000/kcp · C

    KCP is a fast, reliable ARQ protocol for realtime traffic: it trades 10-20% extra bandwidth for 30-40% lower average latency and up to 3x lower maximum latency than TCP.

  7. 10

    go2rtc

    14.4KAlexxIT/go2rtc · Go

    An ultimate camera streaming app: it pulls video from IP cameras and other sources and re-serves it in low-latency formats like WebRTC, HLS and MP4 to browsers and smart home platforms, as a standalone app or embedded into any project.

  8. 11

    supertonic

    13.8Ksupertone-oss-archive/supertonic · Swift

    Supertonic is a lightning-fast, on-device text-to-speech system: it converts text into 44.1kHz 16-bit WAV speech locally via ONNX Runtime — no cloud, no API calls, no GPU. The open-weight model, Supertonic 3, covers 31 languages.

  17. 20

    pyrowave

    761Themaister/pyrowave · C++

    An intra-only video codec — effectively a still-image codec — that runs entirely on the GPU as Vulkan compute shaders: under ~0.1 ms per frame at 1080p and ~0.2 ms at 4K. It is built for local-network game streaming.

  18. 21

    virtio-nvgpu

    431nestrilabs/virtio-nvgpu · Rust

    A virtio device that shares one NVIDIA GPU across several KVM virtual machines at near-bare-metal speed, by forwarding kernel-driver ioctls instead of translating graphics APIs. The target use case is headless streaming: the guest renders and encodes on the GPU, and only compressed video leaves.
