A Plex transcode session always starts producing at zero: the decision request never sent offset=, so any non-zero open - resuming a transcoded title, or switching from Direct Play to a transcoded quality mid-playback - opened a session whose produced window begins at the start of the file and seeked it. mpv immediately requests a segment the transcoder has not produced, PMS answers 404 for it and every subsequent segment, and playback buffers forever. Send offset=<seconds> (6dp) with the decision and start request - the view offset on initial open, the resolved resume position on every in-place reload - so the session begins producing at the position the player consumes first. The playlist timeline is unchanged: an offset session's media playlist still covers the full title from segment zero, so the player keeps opening with start: at the resume position and in-stream seeks work as before. Before a native player opens an offset playlist, waitForTranscodeReady walks the master playlist, the media playlist, and the segment containing the offset, because PMS can publish a manifest before that segment is fetchable and mpv treats the 404 as an HLS error. The probe is best-effort: it never fails an open, hands off immediately on HTTP 500 (on the response and exception paths alike) so the server-limit dialog stays prompt, stops on cancellation, skips itself when the playlist durations never reach the offset, and stays out of the endpoint-failover cascade. In-place reloads resolve the replacement source only after the old stop report has gone out, so Plex cannot use that stop to terminate the replacement transcode. close #1840
