feat(playback): let Rust decide what stream to play, and say so
Playing a video meant asking the server to re-encode it, always. That
decision was made nowhere and written down nowhere, so whoever needed it
re-derived it downstream — the player worked out whether it had been handed
a playlist by looking for ".m3u8" in the URL, in two places. A viewer paid
for a transcode of a file their device could have played untouched, and the
app could not tell them which it was.
One negotiation now produces one self-describing StreamSelection — direct
play, remux or transcode; over a playlist, a plain HTTP file, or a local one
— and every renderer consumes that same answer.
Measured against the development server (Jellyfin 10.11.5), 400 items
sampled for codec mix and 40 put through a real PlaybackInfo negotiation
per profile:
Linux / WebKitGTK (h264 only, 2ch) 3/40 — 7% direct play
Android / ExoPlayer (hevc, ac3/eac3, 6ch) 34/40 — 85% direct play
The library is ~80% hevc, which is why the two diverge so hard. The payoff
is overwhelmingly Android, where 85% of plays were starting a transcode
nobody needed. Linux stays near 7% until libmpv decodes the picture — the
h264-only profile is a WebKitGTK constraint, not a JellyTau choice.
DR-219 StreamSelection: url + tagged Transport (hls/progressive/localFile)
+ PlaybackKind (directPlay/directStream/transcode) + the negotiated
rendition + this source's ladder + a needs_transcoding flag derived
in Rust so the rule is answered once. Both enums are serde-tagged
so the frontend matches a discriminant, not a substring. The paths
that never negotiate get the same shape from Rust rather than
assembling one — media_local_selection for a downloaded file,
LiveStreamInfo.transport for a live channel — so there is no second
place where a transport is decided.
DR-220 The ceiling becomes two levels: a durable device default (Settings,
persisted) and a per-playback override the in-player picker sets.
The picker had called itself a "this film, this connection" control
since it was written but wrote the process-wide default, so dropping
one awkward film to 2 Mbps silently capped every video played
afterwards for the rest of the process, with Settings still showing
the old value. The override is cleared whenever playback moves to a
new item, which stops it surviving into an autoplayed next episode.
effective_streaming_quality() is the single resolution point.
DR-221 The quality picker is filled from what this media source can offer.
Rust marks a rung exceeds_source when its ceiling is at or above the
source's own bitrate — such a rung is another way to spell Original
— and the frontend does not draw those. Original is never marked; a
source whose bitrate the server does not report marks nothing, which
keeps every rung offered.
DR-222 Direct play and direct stream are negotiated, with two client-side
overrides on top because the server's answer is right about the file
and wrong about what this app will do with it: undecodable audio
(Jellyfin 10.11.5 honours a DirectPlayProfile's container and video
codec but ignores its audio codec, so it offers direct play for an
E-AC-3 track the webview renders in silence) and a viewer-pinned
audio track the file does not default to. A direct stream is a remux
and is deliberately not counted as transcoding.
DR-223 Dropped on measurement, not deferred. A master playlist from this
server carries exactly one EXT-X-STREAM-INF: Jellyfin builds it from
the single rendition the request asked for rather than publishing a
ladder. So there is no adaptation for hls.js to be preserving and
none mpv would lose — the claim that there was, in
playback-backend-unification.md, does not hold. Recorded rather than
deleted because it is a measurement: a server that does publish a
ladder would change the answer.
DR-224 Every backend consumes the same selection. The queue item carries
the transport, so player_seek_video picks its seek strategy from the
backend's decision instead of the last stream_url.contains(".m3u8")
in the codebase. Items queued by a path that never negotiated carry
None and fall back to needs_transcoding, which is exact rather than
a guess because every transcode this app requests is HLS (DR-140).
The frontend loader decision moves to streamTransport.ts so it can be
tested: the two cases that pin it are the ones that failed against the old
implementation — a progressive stream whose URL contains ".m3u8" must not
get an HLS loader, and an HLS stream whose URL contains none must.
Also verified the URL the direct-play branch builds actually serves playable
bytes: 206, video/mp4, valid ISO-BMFF, and a mid-file range works, so
seeking a direct play works.
The spec is folded into docs/architecture/{01,02,03} and deleted, per the
rule that docs/specs holds only work that has not shipped. DR-121 leaves
read-through-media-cache.md with a pointer; that spec keeps its capture half.
Not verified: real playback on a device. Direct play changes what actually
gets played, and neither fixtures nor curl prove the WebKitGTK and ExoPlayer
paths render it.

chore(format): run prettier over src/ and scripts/
Formatting was configured but never enforced: `bun run format:check` reported 199 unformatted files and ran in no workflow and in no git hook, so .prettierrc (printWidth 100, trailing commas) described an intention rather than the tree. This is the one-time sweep that makes the check gateable. Whitespace and token-reflow only -- no behavioural change: `bun run check` reports 0 errors and all 1053 frontend tests pass before and after. Kept out of every other commit on purpose. A 199-file diff mixed with real changes is unreviewable, and the next commit turns format:check into a hard CI gate so this cannot silently accumulate again. |

fix(player): make transport reach the player that is actually rendering
Play/pause did nothing on the Android native video path — from the on-screen tap, from the control bar, and from a direct player_toggle invocation — while seek and skip kept working. That asymmetry was the whole clue: seek decides in player_seek_video, transport decides in toggle_playback. DR-195 is the cause. `html5_playing` is Rust's record of "a webview <video> is active and in this state", and toggle_playback/play/pause all route transport to that element whenever it is set. The player route mirrored element state into it UNCONDITIONALLY — from handleReportStart and, fatally, from handleReportProgress, which VideoPlayer calls on a 10-second interval. So on the native path the frontend re-declared every ten seconds that an element was playing when none existed, and every transport intent was emitted into the void. It also explains the flashing: the control bar and the JRay overlay both key off isPlaying, which was being contradicted on every tick. The mirror now lives in mirrorElementStateToRust() in VideoPlayer, gated on useHtml5Element — the only place that knows whether an element renders at all. The route cannot tell the paths apart, which is exactly how it came to lie. DR-193 hands transport authority back to the native backend when an item loads into it. Necessary but insufficient alone: the progress interval put the flag straight back, which is why the first device test after it still failed. DR-192 presents native video through a TextureView instead of a SurfaceView. A SurfaceView renders on its own layer outside the app window and punches a transparent region through it, and everything drawn above that hole — here, the entire Svelte UI — depends on that composition path. The overlay dropped its incremental damage: the DOM advanced (slider 476 -> 479 across three seconds) behind a screen showing neither, so the progress bar froze, controls would not fade and rotation lost the transport UI, while structural DOM changes got through, which is why the play overlay always appeared to work. It supersedes DR-191, which forced redraws in a loop and treated the symptom. DR-194 hides the video view across a resize and reveals it two frames later. A TextureView retains its last frame, so between a rotation and the re-fit landing that frame is stretched across the old rect and the previous frame flashes in what should be the letterbox bars. Verified on device (Honor ROD2-W09, Android 16) by driving ADB and reading the live DOM over the devtools socket: surface tap pauses (position frozen across 12 seconds, overlay raised, transport flipped) and resumes; the control bar does both. UT-189 drives the real 10-second interval under fake timers — an earlier version asserted on a freshly mounted player, passed with the guard deleted, and guarded nothing. Still open, and deliberately not claimed: DR-192's effect on the overlay repaint is unverified on device, DR-194's letterbox reset is untested, and the native default (DR-188) stays off pending DR-190, the background-audio return. |

fix(player): make Android native video actually visible, and usable
DR-172 reverted native video to opt-in after it shipped as audio with no picture, naming the compositing as the suspect. The compositing was fine. Five separate defects sat between ExoPlayer and the screen, each able to produce that exact symptom on its own, and each invisible to the others. DR-185 — the app shell painted over the surface. app.css clears the page's opaque layers through three selectors, one of which targets `[data-app-shell]`, an attribute NO component has ever set, in any commit. The shell paints --color-background across the whole viewport and VideoPlayer stacks above it, so the WebView composited opaque no matter what else was cleared. Invisible three ways over: the CSS is valid, the selector is plausible, and a rule matching nothing looks exactly like a rule matching something already transparent. DR-182 — nothing could lift the poster card. Every markMediaReady() call site is an HTML5 <video> event, and the native branch renders no element, so the black title card covered the surface for the entire session. The first fix hooked `player://position-update` / `player://state-changed`; those channels are never emitted by the backend, so it passed a test that fired them by hand and did nothing on a device. Driven from the player store now, as the seek bar already was. DR-183 — the JS bridges raced the page load. Installed 500ms after onCreate by walking the view tree, while WebView binds injected objects at page-load time, and the identity guard then declined to re-inject forever. setTransparent(true) could never arrive. Installed from WryActivity.onWebViewCreate instead, which wry calls immediately before the first loadUrl. DR-184 — the SurfaceView was never detached. detachVideoSurface had no callers anywhere, mirroring the DR-151 defect: every native video left its surface parented to the content view and the next one stacked another beneath it. DR-191 — the overlay stopped repainting. Incremental damage (the clock's text, the control bar's opacity) never reached the screen while structural changes did, so the progress bar froze, the controls would not fade, and the play overlay appeared to work because it is added and removed from the DOM. Driven from the Activity via postInvalidateOnAnimation while compositing is on. Two UI defects only this path could reveal came with them: isPlaying froze at its initial value, leaving the play overlay dimming and covering the video (DR-186), and the control bar's auto-hide was armed solely by mousemove, which a touchscreen never fires (DR-189). Immersive mode now applies on entering the player rather than only via the fullscreen button (DR-187). Verified on a device (Honor ROD2-W09, Android 16): logcat carries `WebView transparent = true` and `Marking media ready` with video on screen — the pair DR-172 went looking for and could not find — and skip, seek, rotation and subtitle rendering were exercised by hand. The default stays OFF (DR-188). Turning it on surfaced a further unverified sub-path: returning from background audio is HTML5-only, so playback stays dead (DR-190, proposed). Shipping it would have repeated DR-161 exactly — a verified sub-path made default over an unverified one. |
