Tunneled playback on an AFTMM judders continuously through 23.976p direct play.
The #1802 reporter isolated it: turning off Tunneled Playback with every other
setting unchanged makes it smooth, and their log shows tunneling active for the
whole session with E-AC3 bitstreamed and the decoded-PCM guard never firing.
Audio Passthrough looked like the trigger only because it is the one user-facing
switch that decides it. Passthrough off, or Downmix to Stereo on, both force the
Dolby track to decode to PCM, which trips the #1458 guard and takes tunneling
down with it. Passthrough on with downmix off is the only combination that keeps
a bitstreamed track, so it is the only one that stays tunneled.
Withdraw tunneling on that model for content at or below 30fps. The cut-off
keeps 4K50/60 tunneled, which is the workload Amazon documents the feature for.
The mechanism stays unconfirmed: tunneling fires no VideoFrameMetadataListener
and stops media3 counting frames in the codec, so nothing app-side can measure
the cadence. Only the trigger is established, and the quirk is scoped to it.
That needs a frame rate the app did not have. Neither MatroskaExtractor nor
Mp4Extractor populates Format.frameRate, and a tunneled session renders no
frames back for the native detector, so the server's rate now rides on the open
call. It is sent only for direct play, matching _primeDisplayCriteria: a
transcode's metadata describes the source, not what the server is about to send.
Also move Audio Passthrough out of the in-player settings sheet. It configures
the audio output route rather than the current playback, and applying it
mid-stream bounces the audio renderer and re-decides tunneling. Settings > Video
Playback already owns it, next to Tunneled Playback, which is applied the same
way. That description now mentions stutter, not only black HDR video, so the
workaround is findable on hardware this quirk does not cover.
The mpv backend failing to start the same 4K file is a separate defect and is
not addressed here; its uploaded log is no longer retrievable.
Consolidates duplicated logic behind shared implementations — paginated
grid tabs, focus chrome, cached remote stores, sheet selection columns,
the server artifact store and a test fixture layer — and removes code
that had become unreachable. Net reduction of about 5,500 lines with no
behaviour change.
Where a fix had landed separately in code that moved into a shared
helper, the fix was re-applied inside the helper rather than left behind
in the copy that went away.
Introduces shared seams for paginated views, D-pad reorder, media control
routing, async singletons and the device method channel, then points the
open-coded copies at them.
Also removes unused models and duplicated provider/server plumbing, folds
the twice-implemented artifact store in the server, and factors the
repeated Flutter toolchain prologue in CI into a composite action.
Collapse duplicated setup across the suite into six shared helpers under
test/test_helpers/ and rewrite the 28 suites that were open-coding it:
http_fixtures.dart jsonResponse() for http.Response JSON stubs
library_tab_scaffold.dart pumps library tabs under their required ancestors
multi_server_fixtures.dart MultiServerProvider wiring for widget tests
playback_report_fakes.dart PlaybackReportCall + fake report sinks
profile_stack.dart production-shaped profile dependency graph
theme.dart testMonoTokens for fast-settling widget tests
Net -1245 lines with no change in coverage or assertions.
