Frontend
- Replace the Ant Design app with the shadcn/ui app as the single frontend,
keeping the portfolio side-by-side revertible in this commit.
- Drop the abandoned mdui experiment and the AntD tree so there is one app,
one router and one design system to maintain.
Live playback
- Stop racing the encoder. lowLatencyMode + liveSyncDurationCount:1 targeted a
single 4s segment, so playback ran at up to 1.10x and the forward buffer
bottomed out at 0.1s, re-buffering every segment. Measured over 40s:
buffer min 0.1s -> 8.9s, rate 1.00 constant, 0 stalls.
- Remove the 落后 labels and the page-level edge-snapping timer that fought
hls.js over two different definitions of "latency".
- Live can no longer be paused: the control is not rendered while it plays, so
the icon can never misreport state.
- Fix autoplay: muted autoplay started silently and never unmuted, and the
gesture that restored sound also toggled playback off. One owner now.
Source ("原画") rendition
- Publish the publisher's stream remuxed losslessly via -c:v copy alongside the
transcoded ones, so a source option exists even when every ladder entry
downsizes.
- Give renditions an ASCII path slug: the HLS path is part of the URL and
MediaMTX rejects non-alphanumeric paths, so 原画 could never be served.
Backend
- Supervise MediaMTX from the backend: start it at boot and restart it on exit,
never killing an origin it did not start.
- Clear stale HLS output before restarting an encoder; an ENDLIST-less playlist
left by a dead encoder hangs hls.js forever.
- Mark JSON timestamps as UTC. utcnow().isoformat() emitted a naive string that
JS read as local time, so every viewer heartbeat looked 8 hours old in UTC+8
and the live board's active-viewer count was permanently zero.
- Rebind a viewer session when it arrives on another stream instead of failing,
and survive the StrictMode double-heartbeat race on first insert.
- Replace the Linux-only /proc and os.getloadavg metrics with psutil.
- Complete MediaMTX's cookieCheck redirect inside /hls proxying, and hold the
httpx client open for the streamed body.
Housekeeping
- Ignore RainOSS (it stores accessKeySecret), runtime output, TLS keys and
.venv; remove generated screenshots, load test scripts and stray files.
