VIDEO_ENABLED is now permission rather than behaviour: it decides whether
the feature exists at all, while turning it on for a server is a toggle in
the panel or !video in chat, off by default. Video costs real CPU for
every playing channel, so that should be a deliberate choice rather than
something a config flag switches on everywhere.
With the env flag off the panel renders no toggle at all and !video says
so, and the switch applies from the next track — swapping tracks mid-play
would cut the current one.
The loop button no longer reads "выкл" either: it sat next to the video
button showing the same word, so the two states were indistinguishable.
Both now name what they do and rely on highlighting for state.

VIDEO_ENABLED makes the bot publish a second LiveKit track with the
picture. Stoat only grants screen_share in the call token when the bot
has the Video permission and the instance has video enabled, so a refusal
is reported in chat and playback continues with sound alone.
Two constraints shaped the pipeline, both found by testing rather than
assumption:
- Only progressive formats can be streamed. Separate video+audio streams
make yt-dlp download both in full before muxing a single byte, and
direct CDN URLs handed to ffmpeg simply hang — YouTube no longer serves
them to other clients. That caps video at the 360p single file YouTube
offers, and the format is checked before committing to the video path,
since audio would otherwise come from the same broken pipeline.
- One ffmpeg with two outputs, paced by -re: an unpaced decode races
ahead of the sound and eats memory at 1.4 MB per frame.
The same CDN-URL finding removes the audio seek shortcut, which resolved
such a URL and would have hung the same way; seeking now decodes up to
the offset like it already did behind a proxy.

YouTube's bot checks started once traffic went through a proxy exit IP,
while direct downloads had worked. YTDLP_PROXY_SCOPE=search keeps the
proxy on search and metadata — where it is needed to get past filtered
results — and lets the audio stream go out directly. Default stays "all",
so nothing changes unless it is set.
Searches also now run against a throwaway copy of the cookie file: they
run in parallel and yt-dlp rewrites that file on exit, so two of them
could clobber the jar the downloads depend on.

Downloads failed with "Sign in to confirm you're not a bot" even with
cookies and a working proxy. yt-dlp was also warning that no JavaScript
runtime was available: YouTube's player challenges now require one, and
without it extraction degrades into exactly those bot checks.
The image already ships Node, so yt-dlp is pointed at it via
--js-runtimes, but only after confirming the installed build understands
the flag — an older binary would otherwise fail on an unknown option.
Startup logs which runtime was picked and warns when there is none.

A proxy published as 127.0.0.1:1080 is reachable from the host and
nowhere else — not via host.docker.internal either, since loopback
publishing never leaves the host. The fix is a shared docker network and
addressing the proxy by container name, so deploy/ now carries a ready
compose.override.yml example for exactly that, parameterised by
PROXY_NETWORK.
compose.override.yml is gitignored so a local deployment tweak cannot
collide with future pulls, the way the domain edit did.

A proxy pointed at 127.0.0.1 from inside a container reaches the
container itself, and the only sign was a connection error buried in the
first search. Startup now probes the proxy over TCP and says what is
wrong, naming host.docker.internal when loopback was configured.
The README also covers the follow-up trap: even that address fails when
the proxy listens on loopback only, so it shows how to check the bind
address and what to change.

compose.yml was tracked but had to be edited per deployment, so every
update collided with the local change ("your local changes would be
overwritten by merge"). The domain now comes from STOAT_DOMAIN via
compose interpolation, and host.docker.internal is mapped unconditionally
so a host-side proxy needs no edit either. Nothing in compose.yml has to
be touched any more.

YTDLP_PROXY routes every yt-dlp call — search, metadata and the audio
stream, for YouTube and SoundCloud alike — through an http(s) or SOCKS
proxy such as a local Psiphon. Startup logs which proxy is in use with
any credentials stripped.
ffmpeg has no SOCKS support, so with a proxy configured playback always
goes through the yt-dlp pipe instead of a resolved CDN URL: nothing
escapes past the proxy, at the cost of slower seeking. Direct links keep
using ffmpeg, which gets the proxy only when it speaks http(s).
Verified against a dead proxy: requests fail through it rather than
quietly going direct.

A link copied from an open mix (watch?v=…&list=RD…) expanded into the
whole radio station — 500 entries from one paste. Any URL with a `v=`
parameter now resolves to that single track, and only a /playlist?list=…
URL expands. The rule is deliberately blunt rather than keyed on
start_radio, so pasting a link behaves the same way every time.
Playlist expansion is also capped separately from the queue limit
(MAX_PLAYLIST_TRACKS, 100 by default) and the chat says when a playlist
hit that ceiling.
Verified against the real yt-dlp: both mix links resolve to one track, a
plain video link to one, and a playlist URL to its 13 entries.

Search now queries YouTube and SoundCloud together by default and
interleaves the two result lists so neither buries the other; a picker
left of the input narrows it to one source (plus the local library when
configured), and a prefix typed into the query still outranks it.
The panel was capped at 1180px, which left most of a wide screen empty —
it now scales to 1680px and gives the search column the extra room.
A dead link also reported "could not parse yt-dlp's response", which
described our parser rather than the problem; it now shows yt-dlp's own
error line, or says the link did not open.

YouTube applies restricted-mode filtering to programmatic search: the
same query that returns a clip in a signed-in browser comes back as an
empty list over the API, with exit code 0 and no message at all, and
cookies do not change it. Verified locally — "gudium идол" returns three
results, "gudium аудиопорно" returns none, and so does the plain
youtube.com/results page for the same words.
An empty YouTube search now retries on SoundCloud, and when both come up
empty the message says the query may have been filtered and suggests
pasting a link, instead of implying the track does not exist.

Four things people hit while using the panel:
- The bot could be sent into a channel the requester was not in, and
playback could be started from nowhere. Playback now follows the
listener (REQUIRE_LISTENER, on by default), and the voice row shows
where you and the bot are instead of offering a free channel picker.
- Voice presence only refreshed on reload, because the SDK updates
channel participants without emitting an event. The socket now watches
that view and pushes changes.
- The bot left the channel whenever the queue ran dry. It now leaves only
after the last person does, EMPTY_TIMEOUT_SECONDS later (120 by
default), and stays put while anyone is still listening.
- A search that yielded nothing said nothing: yt-dlp can exit 0 with an
empty result, so that case now reports the reason (or "nothing found"),
and searches are logged with their result count.
The queue moved under the player so search owns the left column, and
elapsed time no longer renders as "LIVE" — formatDuration treated 0 as a
live stream, which also affected the chat's progress bar.

Switching tracks killed the process: revoice's #cleanUp() dereferences
this.fProc unconditionally, and its own ffmpeg error handler calls stop()
a second time after stop() has already nulled that field. Killing ffmpeg
is what triggers that error, so its handlers are detached first, the
instance's stop() is wrapped defensively (revoice calls it internally),
and an uncaughtException handler keeps the bot in the channel if the
dependency throws from another async callback.
Failed command-message deletions were logged at debug, i.e. invisible in
the default configuration; they now warn with Stoat's error type, and the
README says which permission the bot's role needs.

The image shipped a year-old yt-dlp, which YouTube now rejects with
"The page needs to be reloaded". Bumped to 2026.08.19 and documented
rebuilding as the standard fix, including how to pass a newer tag
without waiting for a repository update.
A downloader dying mid-stream also looked exactly like a very short
track: ffmpeg saw EOF, the player advanced, and the channel only got
"queue finished". The failure reason now reaches the chat.

Joining a channel failed silently: revoice's join() runs an async
executor inside `new Promise`, so a rejected join_call never reaches
reject() — the promise hangs forever and the real error escapes as an
unhandled rejection. The client wrapper now latches API failures and
settles the join itself, translating Stoat's error codes (AlreadyConnected,
LiveKitUnavailable, UnknownNode, ...) into messages the chat can show.
A failed join also used to leave the connection object alive, which kept
the bot registered in the channel and made the next attempt fail with
AlreadyConnected; it is now destroyed on any failure. The LiveKit node
name is configurable via VOICE_NODE for instances that renamed it, and
the README documents how to clear a stuck voice state from Redis.

revoice.js reads `room.isConnected()`, but @livekit/rtc-node turned that
into a getter, so every join threw "this.room.isConnected is not a
function" before the bot ever reached the channel. The player no longer
touches that getter: readiness comes from the connection's own join /
roomfetched events and is cleared when it reports the offline state.
Also delete the invoking chat message once a command is recognised
(DELETE_COMMAND_MESSAGES, on by default) so channels stay readable;
failures are non-fatal since it needs ManageMessages.

Cookies were already wired up but only mentioned in passing, and the
non-obvious parts were undocumented: yt-dlp has no username/password
support for YouTube, it rewrites the cookie file to persist rotated
cookies (so a read-only file expires early), and the export has to
happen in a private window that is logged out before closing.
Startup now reports whether the cookie file is usable, missing, or
read-only, and YTDLP_EXTRACTOR_ARGS is passed through for the cases
where YouTube blocks a server IP outright.

Cloning straight into /opt fails with "Permission denied", and a clone
left owned by root would also make the ./data bind mount unwritable for
the container's node user.

The instance's internal Caddy is only for Stoat itself, so the panel no
longer goes through it: the bot ships its own compose project, publishes
3005 on loopback, and the host's external Caddy gives it a domain.
extra_hosts pins the instance domain to host-gateway, so the bot reaches
the API, gateway and LiveKit through the external proxy with a valid
certificate instead of depending on router NAT loopback. The old
in-project layout stays available as a fallback example, together with a
step-by-step guide for when voice fails to connect.

Plays audio into Stoat voice channels over LiveKit and exposes the same
player through both chat commands and a browser panel, so the two never
drift apart: everything routes through a single MusicManager.
- core: per-server GuildPlayer (queue, loop, shuffle, seek, volume,
idle auto-leave) driving revoice.js/@livekit/rtc-node and ffmpeg
- sources: yt-dlp for YouTube/SoundCloud, direct media URLs and internet
radio, optional local library with path-traversal guards
- bot: 18 chat commands with aliases, plus !panel one-time login links
- api: Fastify REST + WebSocket, sessions authenticated against the
instance's own /auth/session/login (TOTP supported), permissions
re-checked against Stoat membership and roles on every request
- web: React panel with search, queue editing, seek and volume
- deploy: Dockerfile, compose.override.yml and Caddyfile snippets for
dropping the service into an existing /opt/stoat stack
Verified with npm run typecheck, both builds, and scripts/smoke-api.mjs
(9 API checks). Voice playback itself needs a live instance to test.
