PlexPlayer's session logic (generation, pending play intent, clock ownership, session offset, reclaim
budget, listener teardown) moves into lib/hlsEngine.ts, a plain class with hls.js behind lib/hlsPort.ts
and its own unit tests.
- A seek, track change or reclaim asked for while a session request is out replaces the queued
target; it is sent once the in-flight answer settles. A burst of 20 presses past the buffer was 20
requests and 20 ffmpeg spawns; it is now 2-3, and plays again ~2 s sooner.
- The player stops its server session when it leaves the item, closes or the page unloads
(POST /api/plex/stream/{rk}/session/{sid}/stop, identity-aware). A left transcode used to run to
the end of the film first.
- A restart asked for after a new session attached but before it played no longer reads the emptied
media as the viewer's pause.

"""The playback-session route's mode routing.
|
|
|
|
`POST /stream/{rk}/session` is the single switch that decides how an item plays: a browser-native
|
|
file is served raw (`mode:"direct"`), everything else (re)starts an HLS session — and a
|
|
`playable="transcode"` item (non-h264: HEVC/VP9/AV1/…) must take that HLS path with the video
|
|
RE-ENCODED, not stream-copied. That routing replaced a former `HTTP 501`, and the only thing that
|
|
tells `start_session` to re-encode is the `transcode=` flag this route derives from `it.playable`.
|
|
The command-builder itself is unit-tested in `test_plex_stream.py`; here we pin the ROUTE decision
|
|
(no ffmpeg spawned — `start_session` is stubbed to echo the flag it was handed).
|
|
|
|
DB lane (`db` fixture) — skipped when no Postgres is reachable.
