dtourolle	7660cf219b	docs(specs): restore the stream-selection spec dropped by the squash ... CI caught this, which is what it is for: `check-doc-links.sh` failed because media-player-controller.md links to backend-owned-stream-selection.md twice and the file was not on master. My fault, and worth recording how. That spec was written and committed directly on master early on, before the work moved into a worktree. Squashing the branch began with `git reset --hard` back to the merge base, which dropped those early master-only commits — and the squash then brought in a document referencing one of them. Nothing was lost: the commits are still reachable, and the file is restored from 1d56517f along with its index entries in docs/specs/README.md and the docs site. The lesson is narrower than "be careful with reset": a squash whose base is chosen by hand silently drops anything committed outside the branch being squashed. Only the link checker noticed, because it is the one gate that reads across files rather than within them — and it is also the one gate I had not run locally before pushing. All CI checks now pass locally: boundary, doc links, tooling, format, lint at the 158 ceiling, traces validate, coverage 90%.	2026-08-23 11:08:36 +02:00
dtourolle	11d9d760d8	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.	2026-08-23 10:51:45 +02:00
dtourolle	1d56517f07	docs(specs): add backend-owned stream selection ... Rust becomes the single owner of which stream to play — direct play or transcode, at what ceiling, over what transport — and hands every player backend a self-describing StreamSelection instead of a bare URL. mpv, ExoPlayer and the HTML5/hls.js path all consume one decision rather than three places re-deriving it. The motivating leak is concrete. VideoPlayer.svelte determines transport with `currentStreamUrl.includes(".m3u8")`, in two places, for a URL Rust constructed and therefore already knows the shape of. That is the boundary rule in miniature: not item-type taxonomy, but the same error of reconstructing a domain fact in the presentation layer because the wire shape did not carry it. A tagged Transport enum deletes it. The design line, which ExoPlayer forces: Rust decides *what stream*, the player decides *how to deliver it*. ExoPlayer has genuine adaptive track selection; this spec must not reimplement or fight it. Rust only adapts where the player cannot (mpv) and the server actually offers a ladder. Six phases, and phase 1 stands alone as pure ownership movement with no behaviour change. Phase 4 (direct-play negotiation) is what removes the transcode and unblocks the Linux native-video work. Phase 5 (adaptation) is gated on counting EXT-X-STREAM-INF entries in a real playlist — the acceptance criteria require that count be recorded before it is either started or dropped. Takes DR-121 from read-through-media-cache.md, which specced Rust-owned quality reporting but never built it; that spec keeps its capture half.	2026-08-21 19:41:32 +02:00
