Hardware encoding
- Detect the best usable encoder at startup by encoding a test frame with each
candidate in turn (nvenc, qsv, amf, then libx264). Being compiled into ffmpeg
is not enough: h264_amf fails without amfrt64.dll and h264_qsv fails without an
Intel iGPU, so the probe is the only reliable answer.
- Translate the quality target into the chosen encoder's own vocabulary. libx264's
-crf and "ultrafast" mean nothing to h264_nvenc, which takes -cq and p1..p7, so
passing the configured values straight through would have been silently wrong.
- On the reference GTX 1060 a 1080p->720p rendition costs ~62% of a core on NVENC
versus ~109% on libx264 ultrafast.
Per-rendition supervision
- Track encoder processes per rendition, not per stream. is_running answered
"any alive", so when the source ("原画") encoder died while 1080p and 720p kept
running, the supervisor saw a healthy stream and never restarted it — the
source URL then 404'd permanently. It now requires every rendition to be alive
and reports which ones are down.
- Restart only the dead renditions, so a single failure no longer interrupts
viewers on the renditions that were fine.
Production serving
- Serve the built frontend from FastAPI with SPA fallback, so production is one
process and one port with no Node runtime. Node becomes a build-time dependency.
- start.ps1/start.sh build the frontend on first run instead of failing to a 503.
Cleanup
- Drop the duplicated top-left LIVE badge; the control strip already carries it.

React + TypeScript + Vite
This template provides a minimal setup to get React working in Vite with HMR and some Oxlint rules.
Currently, two official plugins are available:
- @vitejs/plugin-react uses Oxc
- @vitejs/plugin-react-swc uses SWC
React Compiler
The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see this documentation.
Expanding the Oxlint configuration
If you are developing a production application, we recommend enabling type-aware lint rules by installing oxlint-tsgolint and editing .oxlintrc.json:
{
"$schema": "./node_modules/oxlint/configuration_schema.json",
"plugins": ["react", "typescript", "oxc"],
"options": {
"typeAware": true
},
"rules": {
"react/rules-of-hooks": "error",
"react/only-export-components": ["warn", { "allowConstantExport": true }]
}
}
See the Oxlint rules documentation for the full list of rules and categories.
