feat(windows): mpv plays audio on Windows, with libmpv shipped in the installer
libmpv on Windows (DR-237): - The builder image carries zhongfly's LGPL libmpv-2.dll, pinned by asset name and sha256, plus an MSVC mpv.lib generated from the DLL's own mpv_* exports (the archive ships only a MinGW .dll.a). LGPL, not the GPL builds: no x264/x265, mpv -Dgpl=false; FFmpeg is version3, so LGPL-3.0. THIRD_PARTY_NOTICES.md records it. - build-windows-cross.sh stages both files into src-tauri/windows-libs/; build.rs links mpv.lib from there and tauri.windows.conf.json bundles the DLL beside jellytau.exe from there, with the licence texts under licenses/. One directory, so the DLL shipped is the one linked. - Workflows move to builder image 2026.09.1. Windows audio: - MpvBackend replaces WebviewAudioBackend on Windows (ao=wasapi), so volume, EQ, normalization and gapless work there as on Linux. Local files are passed to mpv as native paths, not file:// URLs. Fixes found on the way: - player_play_item decided "does the backend render video" with cfg!(not(linux)), true on Windows, while get_player_status sent Windows video to the <video> element. With mpv as the backend that would decode every film's soundtrack twice. All three callers now ask video_renders_natively() (UT-273). - confine_queued_path rebuilt paths with PathBuf::push, so on Windows a queued `downloads/x` was stored as `downloads\x`, no longer the spelling the app built. It now keeps the caller's separator (UT-205, which only ever ran on Linux, failed under Windows). Verified: jellytau.exe imports libmpv-2.dll; the full unit suite cross-compiled for Windows passes under wine against the shipped DLL (943/943, including the mpv injection and TLS tests); the NSIS installer contains the DLL and licence texts. Not yet run on real Windows hardware. |

fix(player): mpv draws all Linux video, and no longer runs text from a URL
Security (DR-298, DR-299): - The pinned libmpv crate's Mpv::command joins its arguments and calls mpv_command_string, which parses `;` as a command separator. Stream URLs carry server-controlled ids and TranscodingUrl, and a download's file:// path carries its track title, so a crafted title could run any mpv command, `run` included. Every call now goes through mpv_command::command, an argv built for mpv_command. The same parse broke loadfile for every downloaded title containing a space. - mpv's tls-verify defaults to no, and its URLs carry the ApiKey. Every handle is now hardened with tls-verify=yes and ytdl=no before its first loadfile, and fails construction if it cannot be. Linux video (DR-235 phase 1): - native_video::enabled() is unconditional on Linux; the JELLYTAU_NATIVE_VIDEO opt-in is retired. No platform reports a webview video fallback, so the Settings switch no longer appears. Windows keeps the webview element until mpv reaches it (DR-237). - The Linux device profile is unchanged (still h264, DR-234), so this ships the configuration that was tested under the env var. |

feat(player): native video on Linux, and one contract for every player (v0.11.0)
mpv now decodes video on Linux, drawn into a framebuffer we own and blitted
into the default vbox's draw handler. Tauri's widget tree is untouched, so an
upgrade that assumes its own layout cannot invalidate this. Direct play means
the original file, hardware decoding, and no server transcode at all — where
previously every desktop video was re-encoded to h264 for the browser engine,
whatever the file actually was. Off by default: JELLYTAU_NATIVE_VIDEO=1.
That settles finding 2 of playback-backend-unification.md — "native video
cannot be composited with a Tauri webview" — by demonstration rather than
argument, on X11 and Wayland both.
Turning it on exposed nine defects, none of them mpv's. Each was the same
mistake in a different place: a capability written down as a compile-time fact
about the platform, or a state asserted instead of confirmed.
DR-238/246 a seek routed by the stream's container rather than by what the
engine could do with it - correct only while one player handled
those streams, silent the moment another did
DR-239 a property handled but never observed, so the play/pause button
waited for an event that could not arrive
DR-240 fullscreen expanding the document while the window stayed put
DR-241 a seek issued before the engine had a file, failed, and discarded
- which is why resume began at zero
DR-247 a Linux-only gate outliving the caller that made it Linux-only,
breaking the Android build outright
DR-250 a stop aimed at whichever renderer bookkeeping believed was in
charge, missing the one actually making sound
DR-251 a duration of zero believed, leaving the seek bar no scale
DR-252 a junk float converted to a Duration, panicking the backend the
instant a length-less stream appeared
So the MediaPlayer contract (DR-242 … DR-247): `open` carries a start position,
so no caller sequences load-then-seek and none can race an engine's load;
`seek` states a destination and leaves in-place-versus-re-open to the engine;
`snapshot` is one coherent read; and `Phase::Opening` names the window where
intent used to be lost. One conformance suite runs against every engine —
FakePlayer and mpv under cargo test, ExoPlayer instrumented on a device — so an
engine is either correct or visibly failing.
Two of the nine were introduced during this work and caught on hardware, not by
any suite: an over-broad capability that grouped ExoPlayer with mpv, and the
Duration panic. The suites test engines that behave. That is recorded in
docs/native-player-verification.md, which asks for the exact action sequences
that found them.
Verified: all automated gates, conformance (mpv 9/9, legacy 8/9 by design,
ExoPlayer 7/7 on device), and manual desktop and Android passes on real
hardware.
Known open and deliberately shipped: resume reads local progress and never the
server's; the background-audio handoff still declares a state swap it does not
confirm (the symptom is now impossible, the race is not); and `bun run
android:dev` builds an APK carrying the release application id, whose failure
message advises an uninstall that would destroy app data. Fix that last one
before anyone else builds for Android.
Squashed from worktree-linux-native-video, which keeps the per-defect history.
