A player whose predecessor had not released the shared native channel
within three seconds skipped its own native dispose and chained its
release onto that predecessor. If the predecessor's teardown never
completed - one hung 4K session was enough - every later player waited
on the chain, failed to initialize, and playback stayed broken with
"Playback could not be started" until the app was killed.
Initialize and dispose now carry the creating instance's token. The
Android plugins remember which token created the current core and
acknowledge a dispose from any other token without touching the core,
so a dispose that lost the ownership race is provably stale and safe to
send. With that guard, a timed-out ownership wait force-disposes
instead of skipping, settles its release unchained, and frees the
channel for the next session; a dispose watchdog answers Dart even if
a native teardown hangs, leaking that one core instead of wedging all
future playback. Commands wait eight seconds (was three) so a slow but
healthy teardown delays the next session instead of failing it.
Verified on a Shield Pro: 38 back-to-back session races at 0.8-2.2s
gaps with zero failures and balanced teardowns, and a deep-link-over-
playback collision whose stale dispose is ignored, after which Back
returns to the still-playing session and Retry starts the new one.
Apple and desktop handlers ignore the token and keep the historical
skip semantics until they gain the guard.
Sub-4K content on a 4K TV was always upscaled by the playback device, so the TV's own (usually better) upscaler never received the native signal and could not apply resolution-specific processing.
Adds a Match Content Resolution setting on Android TV: playback picks the smallest display mode that still contains the video — never downscaling it — and rate-matches within that resolution when frame rate matching is also enabled. A resolution-only switch keeps the refresh rate as close to the current one as possible, and the settle watchdog now verifies the requested mode id so such switches still trigger the Android MPV decoder refresh. Transcodes get their target from decoded dimensions on the post-first-frame path. Mode selection is extracted into a pure, JVM-tested DisplayModeSelector.

Nothing sat between the full-screen `RasterizedGradient` scrim and the
position-driven leaves, so `markNeedsPaint` from the timeline slider walked past
the gradient and re-rasterized the entire chrome -- top bar, button row,
timestamps, timeline -- on every 250 ms position tick. That also partly defeated
`RasterizedGradient`, which exists because Skia gradients cost ~10 ms per
full-screen pass on this GPU class.
Around that, four things drove root `setState` calls that only needed to change a
leaf:
- Held D-pad seek called a root `setState` per key repeat, even when the readout
was already visible in the same direction and only the accumulated seconds had
changed. The seek amount now flows through a `ValueNotifier` that
`DoubleTapFeedback` reads, so a burst updates one `Text`.
- `DoubleTapFeedback`'s drift chevron ran `..repeat()` with no stop condition, and
kept ticking at 60 Hz for the ~300 ms the readout spends at zero opacity after
every burst. The controller is now gated on visibility.
- The auto-skip countdown ran a 5 Hz timer that root-`setState`d the controls tree
for the whole intro/credits window, to animate one progress ring.
- The play-next and still-watching countdowns root-`setState`d the player screen
once a second, which re-created `PlexVideoControls` with its ~50 props and
rebuilt the entire chrome to change one digit. Prompt open/close deliberately
stays on the state path, because `playNextFocusNode` is threaded through those
props and D-pad focus depends on it.
Two of the four position subscribers existed only to recompute pointer-hover
tooltips that a D-pad viewer never sees, rebuilding a button subtree 4x/s and
rescanning the chapter list each time; the "ends at" readout reformatted a string
4x/s for a value that changes once a minute. All three now dedupe.
Finally, the buffer path did two sequential `copyWith` calls on a 15-field
`PlayerState` and handed `BufferRangePainter` a freshly allocated list every tick.
`List` has no value equality, so `shouldRepaint` was unconditionally true.
Measured on device during playback with the chrome raised: 6 of 344 UI frames over
budget, p50 4.39 ms, layout p90 1.09 ms. During a held D-pad seek -- the worst
frame-time window on the TV path, because the readout and the decoder flush land in
the same frames -- 1 of 354 frames over budget, p50 4.28 ms, zero raster frames over
budget.
On the default Android ExoPlayer backend the native core never emits a speed property, so PlayerState.rate stayed at 1.0 forever: the speed sheet checkmark, keyboard speed stepping, long-press 2x restore, and media-session rate all computed from a stale 1.0. setRate now mirrors its value into state like setVolume already did.
On mpv backends, a selected --secondary-sid subtitle later in track-list order overwrote the primary selection because parsing ignored main-selection; the track sheet then badged the secondary as primary and replaced the user's primary on tap. parseTrackList now treats main-selection 0/absent as primary and 1 as the secondary selection.
Audio Normalization on the mpv path made every video start with stuttering
audio on Linux: dynamic-mode loudnorm always outputs float64 at 192 kHz, so
the AO opened at f64/192k and PipeWire had to convert/resample on the
deadline-critical path (~4x the per-cycle DSP work) while playback startup
load was still settling. Appending mpv's native format filter pins the
chain back to 48 kHz float, so the conversion happens once on the buffered
decode side and the AO opens a normal stream. Integrated loudness output is
unchanged (-14 LUFS, verified via ebur128). mpv's own format filter is used
instead of lavfi aformat so the fix does not depend on which lavfi filters
each platform's bundled ffmpeg compiles in.
Addresses the normalization half of #1720; the residual startup
micro-stutter with normalization disabled is a separate regression.
PlexMediaItem.subtitleMode/extraType were mapped from DTOs and never read (subtype stays — the detail screen's trailer picker destructures it); MediaPlaylist.copyWith, PagedMediaListState.mapItems, isMusicContent/isCollection, and MediaHub.copyWith's eight never-passed params had zero call sites; LiveTvActivityResult wrapped reloadGuide results nobody unwrapped (now Future<void>); PlayerLogLevel.none was unreachable — nothing parses or produces it; MediaSourceInfo.getPartId() was an accessor over its own public field.
The display-agnostic texture renderer restored by 9cdfe759 is deleted
again, this time for good: it is a second, SDR-only rendering stack
(isolated EGL context on Flutter's display plus EGL-image handoff) kept
alive solely to host sessions that cannot bring up the Wayland plane -
X11/XWayland or a failed plane bootstrap - and it was the source of the
native lifecycle and EGL state-churn fixes of the 9f2e0507 era. Linux
video now requires a Wayland compositor; a session that cannot host the
plane fails initialization with VIDEO_PLANE_UNSUPPORTED instead of
silently rendering through the second stack.
Reverts the restore commit's machinery: mpv_texture.cc/.h and
mpv_gpu_bootstrap.cc/.h deleted, the plugin's texture-registrar,
bootstrap, and waitForVideoReady paths removed, MpvPlayer's texture-mode
render-context API dropped, and the Dart-side renderMode setting, its
settings tile, translation keys, and the Player textureId member
withdrawn. The #1874 HDR diagnostic work is unaffected.
2.13.0 deleted the display-agnostic EGL/Flutter-texture renderer and made
the native Wayland plane the only path, hard-rejecting every session that
cannot host one - X11, XWayland (SteamOS Gaming Mode runs native apps
through Gamescope's XWayland), or a plane whose EGL bootstrap failed. This
restores the 2.11.0 texture path from git history as the fallback:
- Re-add mpv_texture.cc/.h and mpv_gpu_bootstrap.cc/.h (2.11.0 verbatim):
an FlTextureGL whose populate renders mpv into an offscreen FBO sampled
by Flutter via an EGL image.
- MpvPlayer gains the texture-mode render-context API (InitRenderContext,
HasRenderContext, GetEglDisplay/Context, Render(w,h,fbo)) beside the
plane's InitRenderContextForSurface/RenderToSurface. The isolated ES 2.0
context on Flutter's display and the X11 display param are exactly the
2.11.0 configuration hardware decode demonstrably worked in.
- initialize now tries the plane first and falls back to the texture path
when it cannot be brought up, returning the texture id (Dart's 2.11.0
'result is int' contract) with waitForVideoReady gating playback until
the GPU bootstrap settles. Both paths share one mpv core, so the
plane/texture decision precedes render-context creation.
- hdr-enabled/hdr-tone-mapping are intercepted in texture mode (no plane,
no HDR); the HDR toggle hides itself via isHDRSupported.
- New Linux setting 'Video rendering mode' (Automatic / Texture) forces
the fallback - the user-visible workaround for plane-only trouble and
for the hwdec interop regression, plus translations in all locales.
SDR only on the fallback, matching 2.11.0; the plane path is unchanged.
Nonzero mpv video-zoom flips vo_avfoundation into a per-frame Core
Image re-render that destroys HDR/DV passthrough - DV frames render
near-black on tvOS (verified on Apple TV 4K, DV P7->8.1 content:
panel luma mean 0.0 zoomed vs 87-103 unzoomed at locked exposure).
Zoom now scales the AVSampleBufferDisplayLayer itself (a
sublayerTransform on the container is ignored by the video plane)
via the existing Player.setVideoZoom seam, and VideoFilterManager
pins the mpv property to 0 on backends with native zoom. The layer
tree at 100% stays identical to before: clipping engages only while
zoomed, and updateFrame sizes the layer via bounds/position, which
frame= decomposes to anyway.
macOS keeps the property path (gpu-next zooms losslessly in-shader);
Android is untouched.
Video on Linux went through a Flutter texture: 8-bit sRGB, which cannot carry
HDR at all, and which forced a whole-window Flutter recomposite for every video
frame. This moves it onto a wl_subsurface stacked below the Flutter surface, with
mpv rendering into an EGL window surface on it through the libmpv render API. The
subsurface is desynchronized, so video and UI now present independently.
With the plane in place HDR follows: the surface is described to the compositor
through wp_color_manager_v1 as the source's own curve and gamut - PQ or HLG,
BT.2020 - carrying whatever HDR10 static metadata the stream actually declares.
The description and the buffer it describes land on the same commit, staged and
validated before mpv is switched, so a PQ frame is never presented labelled sRGB.
A five-second watchdog bounds the one wait a compositor could otherwise leave
hanging. A session that cannot host the plane - X11, or a compositor without
wl_subcompositor - fails initialize with VIDEO_PLANE_UNSUPPORTED naming the
reason: the texture path is gone, and refusing by name beats degrading to
something the user cannot see. An SDR output, a missing capability or an 8-bit
config keep the plane and simply leave it undescribed.
The output's colour state is trusted only when it has been earned. Every landed
property step records itself as it lands; a reset or sequence that cannot
finish downgrades its result to unknown and marks the applied-output cache
untrusted until a clean apply earns it back. A plane whose output state cannot
be named is quarantined - hidden, its description withdrawn - and the
quarantine is recorded state: an unrelated visibility change cannot put a
mislabelled plane back on screen, and only a commit that resolves to a nameable
outcome lifts it. A rect collapsing to zero detaches the buffer exactly as
hiding does, a refused setVideoRect drops the Dart-side sent-rect cache so the
next layout pass retries for free, and a refused tone-mapping pick tells the
user instead of dying in a log.
NVIDIA's Wayland EGL (through at least 610.xx) offers no 10-bit unorm window
configs, so the plane takes half-float as the tier between 10-bit unorm and
8-bit, declares the whole surface opaque so the compositor never reads the
alpha those configs carry, and states GL_RGBA16F rather than a 10-bit lie.
Whether the output is in HDR is read from luminance headroom above its own
reference white rather than from the preferred transfer function, which current
KWin no longer answers PQ for; the margin is half a stop, because KWin reports
an undimmed maximum over a software-dimmed SDR white. Validated on an RTX 4090
(driver 610.57.04) under KWin 6.7.4 with locked-exposure photographs.
Who tone-maps is a user choice. The default is the compositor: photographed on a
400-nit HDR output against a PQ chart it keeps 400 -> 1000 nits monotonic and
separated where the player leg flattens them, because the player path drives
mpv's legacy vo_gpu, whose own standalone output scores the same. The gap is the
renderer, not the wiring.
The decision itself - what the source carries, what the output supports, what to
tell mpv and what to tell the compositor - lives in hdr_metadata.h, free of
Wayland and GTK so its luminance validation can be tested without a display
server. Sending an incoherent luminance set is a protocol error that disconnects
the client, so the rules are worth a unit test.
The deb, rpm and pacman packages now declare wayland-client, wayland-egl and EGL:
the plane links them directly and bundle-libs.sh deliberately never bundles them,
since they are coupled to the running compositor and GPU driver.
lib/dev/harness_main.dart is a second entrypoint for measuring this on hardware -
it drives one clip with scripted mpv properties and reports the colour state mpv
actually settled on. Nothing imports it, so it is tree-shaken out of the app.
Verified on a Steam Deck against an external 400-nit HDR display: the compositor
reports PQ / BT.2020, the connector carries HDR_OUTPUT_METADATA, and against mpv
vo=gpu-next on the same frame the shipped build sits 4.90 counts away overall -
closer to the reference HDR player than to its own SDR fallback.
Adds an "Anchor to Screen" toggle under Subtitle Styling (Android +
ExoPlayer only, default off). When enabled, the text SubtitleView is
sized to the full container instead of the letterboxed video rect, so
SRT/VTT/mov_text cues render in the black bars below widescreen video
and font size and the position setting become relative to the physical
screen height. Bitmap (PGS/VOB) and ASS/libass rendering are unchanged;
mpv already places plaintext subtitles in the margins by default.

ffmpeg's reconnect loop deliberately retries 503 without bound (#1520), so a
server that keeps refusing the stream at open time left a silent black screen:
ExoPlayer fell back to MPV, MPV reconnected forever, and no error ever reached
the screen. A new open-phase watchdog arms on the first 503 seen before any
frame renders and, after 20s without one, synthesizes a server-http-503 error
that shows an actionable dialog. Mid-stream 503s and live TV keep their
existing ride-out paths.
close#1830
A coalesced key-repeat skip pins its target so a slow backend cannot make
the next press rebase off a position the seek has not reached yet. Nothing
retired that pin when something else moved the playhead, so for the ten
seconds it survived, a skip taken after a timeline tap, a chapter jump, an
OS media control or a peer sync resumed from the superseded target and threw
the user back across their own jump.
Publish every playhead movement on the player and retire the pin whenever
the announced destination is not the accumulator's own commit. Overlapping
seeks and backend-chosen relocations arbitrate by which operation the
backend accepted, so a request that was merely asked for cannot speak for
where the playhead ended up.
close#1819
A 404 on the media stream means the server resolved the item but could not
open the file behind it — moved, deleted, or on storage that went away.
Jellyfin maps the resulting FileNotFoundException to 404, and PlaybackInfo
never stats the file, so negotiation succeeds and only the stream request
fails. Playback then died with a snackbar reading "Failed to open
[REDACTED_URL]" before popping the route, which tells the user nothing and
leaves nothing useful in a bug report.
Generalize the HTTP-500 log probe into PlayerError.httpStatusFromLog and
latch every status in fatalPlaybackHttpStatuses. Each latches on its own so
the 503 that stream-lavf-o deliberately retries cannot mask the fatal status
behind it. A 404 now raises a dedicated modal naming the cause and the fix.
On Android a 404 previously failed the "Response code: 500" string test and
fell through to the ExoPlayer→MPV fallback, showing "switching to compatible
player" before failing again on the same request. Read the real status off
HttpDataSource.InvalidResponseCodeException instead and skip the fallback:
an HTTP status is not a codec problem.
Groundwork for #1300. Establishes the session, buffering and route
handling Dolby's application guide prescribes, and adds the diagnostic
arm needed to find out whether Apple's sample-buffer renderer can carry
Atmos objects at all.
Audio session, per the guide's sequence:
- Adopt the long-form playback profile in one atomic call at app launch
and activate the session there. The SDK only accepts that policy with
category Playback, a Default/MoviePlayback/SpokenAudio mode and no
options, so it cannot be assembled from separate calls.
- Report the resolved rendering mode in the player, hidden unless the
system resolves it. Apple only resolves it for CarPlay and AirPlay, so
an unresolved value means unknown, never "not Dolby".
Diagnostics (Apple TV only, Settings > Video Playback > Atmos Output Test):
- Add a sample-buffer arm. It reads the asset with AVAssetReader at
outputSettings nil and hands the untouched compressed buffers and the
untouched format description straight to the renderer, with a variant
that rebuilds the description the way playback builds it. Every
existing mode went through AVPlayer, so nothing exercised the path
playback actually uses; this is what tells us whether the renderer or
our construction is at fault.
- Add an AirPlay route picker. AirPlay is the only route where the system
resolves the rendering mode and the supported channel layouts, so it is
what makes those observations reachable at all, and the AVPlayer arms
now allow external playback so every arm can be compared on the same
destination.
- Add a session-mode toggle for the one profile difference between the
guide and previous playback behaviour.
- Report the session profile, supported layouts, both format
descriptions, the magic cookie and the renderer status, and release the
session on stop so a failed run cannot contaminate the next one.
Also bumps MPVKit to 1.0.14, which carries the matching audio output
work: the channel layout AVFoundation itself uses for Dolby content, a
renderer-failure observer so the fallback to PCM can actually run, the
prescribed feed ordering and preroll, flush recovery that re-supplies the
discarded audio instead of shifting later audio into its place, and
capability-driven fallback on route and capability changes.
This does not yet fix#1300. Whether the sample-buffer renderer can carry
JOC is still unknown; it removes every difference from the documented
setup that could explain the failure, and gives us the arm to answer it
on real hardware.
Audio-only mpv core on every platform (dedicated
com.plezy/mpv_audio_player channels): parameterized android/windows/
linux mpv plugins and a new apple MpvAudioPlayerCore, all skipping
video/window paths (vid=no, audio-display=no, gapless-audio=weak).
MusicPlaybackService drives an in-memory queue with shuffle/repeat,
file-loaded-event gapless arming (property edges coalesce and the
android bridge drops them), per-track progress reporting, OS media
controls, audio focus, sleep timer, and error auto-skip.
PlaybackCoordinator enforces one live native player: starting video
disposes the audio core first.
Player backends share static per-backend EventChannel names, so two
overlapping instances (episode handoff, quick exit/reopen) collide:
the newer instance's listen displaces the older sink, the older
instance's late cancel then tears down the newer stream — silently
freezing its events — and the final cancel earns the engine's
"No active stream to cancel" reply, which the framework can only
report as an uncatchable fatal FlutterError (363 events).
Track the owning instance per channel: only the current owner sends
the native cancel; a displaced instance drops its dead subscription.
Residual benign teardown races are dropped in beforeSend.
