Der atomare Ersetzen-Schritt loeschte das Original bevor der Ersatz bestaetigt
war; schlug das anschliessende Rename fehl (z.B. AV/Indexer-Lock), raeumte der
aeussere catch zusaetzlich die Temp-Datei weg -> null Kopien auf der Platte.
- Atomares Replace-over (MoveFileEx REPLACE_EXISTING / rename(2)) statt
rm-dann-rename: filePath haelt zu jedem Zeitpunkt entweder das volle Original
oder den vollen Remux.
- renameWithRetry: transiente Locks (EBUSY/EACCES/EPERM/EEXIST) mit Backoff
(200/500/1000ms) statt sofort abzubrechen.
- Eindeutiger Temp-Name (~rd<pid><rand>) statt fixem ~rdtmp -> keine Kollision
zwischen parallelen Paketen/Retries.
- 3 neue Tests (Recovery bei Replace-Fehler, Retry-Pfad EBUSY/EXDEV).
- tag mode: when no German-tagged audio track is found but the release name
says German/Dubbed, fall back to the first track (the dub is mislabeled, e.g.
German tagged "eng") instead of skipping; non-German names still skip safely
- comprehensive logging: per-package ffmpeg/ffprobe availability, plus per-file
detected audio languages, decision + reason, remux/rename result and the exact
error text when a file can't be processed
- shorter same-dir temp name so a long scene path + temp suffix cannot exceed
Windows MAX_PATH and silently fail the remux
- New video-processor.ts: ffmpeg/ffprobe remux that keeps only the German
audio track (by language tag, with safe fallbacks) and strips the ".DL."
marker from the filename
- Runs after extraction in both the deferred and hybrid post-process paths,
inside the per-package file-op chain; abortable, disk-space checked,
mtime-preserving, atomic temp->replace so the original is never lost
- System ffmpeg via PATH / RD_FFMPEG_BIN; toggle + track-mode select in settings
