Thread cap didn't move the thermals, so the real culprit is likely
dried-out thermal paste rather than concurrency. Reverting to the
unbounded default while the compound gets redone; running one stream
at a time is enough of a workaround in the meantime.

Concurrent transcodes on the 56-core mediaserver were running hot.
Limits each ffmpeg invocation to 8 threads via -threads and x265's
pools= param (libx265 ignores -threads alone). Overridable with
TRANSCODE_THREADS env var.

Parse every Saved: entry in the log to compute cumulative original
size, new size, bytes saved, and percentage reduction so we have a
single command for the transcode impact.

Removes any .transcode-* files left behind by interrupted runs
before starting the encoding loop.

Map only the first video stream, all audio, and all subtitles instead
of mapping everything. This avoids feeding cover art images through
the libx265 encoder which caused hangs.

Queries qBittorrent for individual file sizes of all active torrents.
Files whose size matches a seeded torrent file are skipped, catching
cross-filesystem copies where hardlink detection doesn't work.

Files with multiple hardlinks are likely linked from downloads/ where
they are still being seeded. Transcoding would break the hardlink and
cause both copies to take up disk space separately.

MP4 containers don't support all subtitle/codec combinations with HEVC.
MKV handles everything, so always output .mkv and remove the original
if it was a different format.

Resumable batch script that finds H.264 files, re-encodes to HEVC
(libx265 CRF 24), verifies duration, and replaces originals.
Tracks completed files in /var/lib/transcode-hevc/completed.log.
