Correctness fixes in GlobalMediaPlayer.kt
- snapshotFlow { hasMedia } collector for initial seek used `return@collect`
which only exits the lambda; the collector kept running and each
subsequent playVideo() call accumulated a live collector that would
re-fire a stale seekTo() on the wrong media. Replaced with `Flow.first`
which terminates the collection cleanly.
- playVideo()/playAudio() reset the public MediaPlaybackState to
volume=100/isMuted=false on a new URL, but the kdroidFilter player
retains its `volume` across openUri(); muting one track and starting a
new one left the engine silent while the UI showed unmuted. Reset
`player.volume = 1f` to match the public state.
- ensureVideoPlayer()/ensureAudioPlayer() called createVideoPlayerState()
synchronously from the Compose getter; if native init throws (missing
GStreamer on Linux, broken NativeLibraryLoader extraction) the whole
window would crash. Wrapped in runCatching and changed
activeVideoPlayerState to nullable. Consumers in DesktopVideoPlayer
and GlobalFullscreenOverlay handle the null path by rendering the
thumbnail / blank backdrop respectively; playVideo()/playAudio()
surface "Video playback unavailable" through the existing
errorReason -> PlaybackErrorMessage path.
Crash mitigation (kdroidFilter 0.10.0 UAF in MacVideoPlayerSurface)
- NowPlayingBar previously mounted a SECOND VideoPlayerSurface against
the same VideoPlayerState while the feed card was already mounting
one, doubling the draw rate against the shared frame bitmap and
widening the UAF window in MacVideoPlayerSurface's RasterFromBitmap
path. Mini-preview now renders the cached thumbnail (or the music
icon fallback). 0.10.1 contains an upstream fix
("recover video playback after composition removal") but is not yet
on Maven Central — single-surface mounting is the only mitigation
we can ship today.
VideoThumbnailCache.kt
- Truncated-download cache poisoning: when an origin ignored the
Range: header and returned HTTP 200 with the full body, we capped
the copy at MAX_THUMB_BYTES and persisted the truncated file
forever. Subsequent thumbnail attempts hit the broken cache file
and re-failed JCodec/ffmpeg every time. Tag download results with
whether the server actually returned 206; on 200, extract from the
temp file and delete it (no persistent cache hit).
- Tor bypass: replaced the bare OkHttpClient with
DesktopHttpClient.currentClient() so thumbnail fetches respect the
user's Tor preference (fail-closed when Tor is expected but
bootstrapping).
- ffmpeg version probe leaked the process on hang: now drains stdout
to DISCARD and calls destroyForcibly() on timeout.
- Frame-extract ffmpeg subprocess could deadlock on a chatty stderr
pipe: redirectError(DISCARD) so we never wait on stderr; a finally
block destroys the process if anything leaked through the timeout.
CI workflow cleanup
- Removed vlc-setup download cache + pre-fetch steps from
build.yml and smoke-test-desktop.yml. They were targeting an
ir.mahozad.vlc-setup plugin we no longer apply, so they wasted
~minutes of CI time per leg and tied the build to videolan.org
reachability for no reason.
- Trimmed create-release.yml's stale VLC-plugins justification on
the linuxdeploy-vs-appimagetool comment.
.gitignore + missing per-OS ffmpeg READMEs
- The pre-PR rules blanket-ignored desktopApp/src/jvmMain/appResources/{linux,macos,windows}/
so the LGPL FFmpeg drop-in slot READMEs created in 704f4f44e never
reached the commit. Refined the ignore rules to keep stale vlc/ workspace
trees out of git (still ignored) while explicitly tracking the
ffmpeg/README.md drop-in slot under each OS. The READMEs document the
recommended LGPL build source per OS for the bundled-FFmpeg packaging
path.

Refs PR #3175 review by @davotoula.
Zulu's CDN (cdn.azul.com) has been returning HTTP 520 for several
hours, breaking JDK 21 setup across multiple PRs (#3075, #3095) on
every Linux runner. actions/setup-java's internal retry budget isn't
enough to ride through it.
Temurin (Adoptium) publishes its JDKs as GitHub Releases assets, so
the download path uses GitHub's own CDN — completely independent
infrastructure. Java 21 is the same upstream OpenJDK build either way,
so Gradle, Compose Multiplatform, and jpackage behave identically.
Applied to all setup-java steps in build.yml, smoke-test-desktop.yml,
and create-release.yml.
The smoke test discovered that ProGuard's method/marking/static pass
converts kmp-tor's AsyncFs.of() from instance to static. The JVM
then throws IncompatibleClassChangeError at launch because callers
still use invokevirtual.
Also updates smoke-test-desktop.yml trigger: runs on any PR touching
desktopApp/ (not just build config files).

dpkg -i exits non-zero when the post-install script fails even with
--force-all. Allow the error with || true, then verify the binary
was actually extracted to /opt before proceeding.

jpackage's post-install script calls xdg-desktop-menu which fails on
GitHub Actions runners with "No writable system menu directory found".
Menu registration is irrelevant for smoke testing.

Fixes#2819 — v1.08.0 .deb crashed on Ubuntu with ManagementFactory
error because the build had no jlink modules() declaration. Current
main already has the fix; this PR adds CI to prevent regressions.
- Add compose.desktop.uiTestJUnit4 dependency
- DesktopLaunchSmokeTest: renders LoginScreen, asserts title text
- build.yml: xvfb for Linux leg so UI test runs on every PR
- smoke-test-desktop.yml: builds release .deb, installs it, launches
under xvfb, verifies process stays alive 10s
