Enable bounded FFmpeg reconnection for recorded range-seekable HTTP inputs, preserving compressed cache, byte offset and playback intent. A five-second socket timeout leaves recovery room inside the existing fifteen-second I/O deadline. Keep live/non-range replay and signed-URL refresh disabled.
Native regression failed before the fix with Reading network media: Input/output error. Real combined/split playback now survives dropped responses and socket timeout; persistent failures remain visible and retries are cancellable by seek, close, replacement and destruction.
Release, network, adaptive, media, reporting, runtime, relocated bundle and local playback checks passed. Packaged CLI/GUI playback started successfully; the full-suite keyboard smoke stopped because macOS refused foreground focus for its transparent check window.
Build pinned LGPL playback libraries and package standalone YouTube helpers inside the signed native app. Keep the CLI inside the app and relocate private library links for installation without runtime Homebrew dependencies.
Record adaptive fixture completion in its EXIT trap: cancellation can exit with status 143 before the TERM trap writes its marker, while native pause and quality preservation remain correct.
Add make release and make install PREFIX=/Users/valdemar/.local. Keep optimized no-debug release artifacts separate; install adjacent CLI/app under lib/terebi and link bin/terebi. Preflight FFmpeg/pkg-config before compiling or installing, including cached builds.
Record the player's exact linked FFmpeg ABI paths. AppKit-only CLI/bootstrap validate native loadability and transitive dependencies before entering the FFmpeg-linked terebi-player. CLI fails with status 69 and remediation; Finder bootstrap shows a native alert and execs the player without losing initial events or process identity.
Verified staged installation with spaces, reinstall preservation, absent build dependencies, missing/corrupt/transitively broken dylibs, real modal error surface, installed CLI and Finder startup across exec, local/YouTube resume and window reuse, and full make check.
Build .build/terebi beside the app. Parse a single local file or YouTube URL, --url, --, and help; reject invalid commands before GUI launch. Resolve the adjacent app through symlinks and launch through NSWorkspace, reusing its process/window and saved progress.
Launch the app without media before delivering URL events. Raw media argv suppress SwiftUI's initial singleton window. Own warm document and internet Apple events because SwiftUI's default external-event routing closes that window; retain initial Finder document delivery to create it.
Verified actual CLI 0/64/69 exit behavior, PATH/symlink discovery from another directory, cold local/YouTube playback, warm local/YouTube replacement in the same native window/process, resume, Finder-style cold launch, and make all check.
Persist authoritative per-video positions in UserDefaults. Save periodic checkpoints, pause, close, replacement, and quit; restore a validated position before autoplay. Canonical YouTube webpage URLs survive fresh stream extraction, and local symlinks share file progress.
Clear completed or out-of-duration bookmarks. Leave failed opens and live/non-seekable inputs out of persistence. Pending opens hide errors belonging to the previous source.
Verified separate-process restart, source replacement, failed-open recovery, completion, checkpoints, real YouTube short-link resume, live exclusion, and make all check.
Restore the playback window as first responder after initial setup and after file/YouTube dialogs return. Keep native control focus indicators and Tab navigation unchanged.
Verified hidden native window focus, both dialog cancellations, explicit control focus, Tab navigation, P shortcut, app build, and compact-window checks.
Resolve public YouTube URLs through external yt-dlp and play selected streams in the existing native window.
Independent bounded network readers keep one authored timeline. Successful seeks clear FFmpeg's sticky aborted-read AVIO error; manifest seekability uses native format flags rather than a top-level I/O handle.
Verified real YouTube playback, seeking, frame stepping, compact mode, cancellation, and the complete native regression checks.
