fKey Playback v1.7.6 — Process and Resource Cleanup

fKey Playback v1.7.6 — process and resource cleanup

• Stop output releases resources: close the dedicated browser/window, release its worker lease, cancel pending native requests/retries, free capture textures, and disable browser audio capture. Start queue / retry recreates the output with the saved account session and placement.
• Earlier OBS cleanup: close the output before OBS tears down its scenes/browser framework. Audio capture stops and its thread is joined on source destruction.
• Bounded station shutdown: stop background work before draining HTTP connections, close stalled connections after a deadline, and make cleanup safe to call repeatedly. Release SQLite storage and the instance lock.
• Extractor process cleanup: cancel only the extraction's owned process tree and wait for its exit. Already-cancelled extraction cannot start a process; unrelated processes are preserved.

Shared OBS browser processes can remain while other OBS sources need them. Minimizing or closing a locked output still parks it intentionally for continued capture; use Stop output to release it. These fixes retain the video transitions, pause fix and saved-position protections from prior releases.

Downloads and upgrade

• Playback-v1.7.6.zip — updated station app and plugin source.
• fKey-Playback-OBS-Plugin-Setup-0.1.7.exe — updated Windows installer.
• fplayback-youtube-0.1.7-windows-x64.zip — installer, DLL, corresponding source and license.
• Each download has a SHA-256 checksum.

Update both the station app and plugin. Stop Playback, back up and preserve data/ and launcher configuration, extract the app update, then restart. Close OBS, run the plugin installer, and restart OBS normally. This build requires Windows x64 and OBS 32.2.2 / Qt 6.11.1; the app requires Node.js 22.13 or newer. No database migration is needed. Queues, settings and account data are preserved. Sign-in and access/age/content confirmations remain manual.

Validation

All 175 app tests, JavaScript syntax checks and six native tests pass. New tests verify stalled HTTP shutdown, extraction abort, owned child-tree cleanup without killing an unrelated process, idempotent cleanup and lock release, and an actual station process exiting naturally without forced termination. Live OBS Stop/Start closed and recreated the dedicated renderer and worker lease. Full OBS shutdown left zero tracked OBS/browser processes running.
