The feed switches to a static league slate and keeps serving at full CBR bitrate. No end marker, and no stall to detect, so neither of the obvious exit conditions fires. The duration cap is the only stop condition. Observed on a live match: 116 min recorded, still running 2h04m after kickoff, stopped manually.

# on #EXT-X-ENDLIST, or does it hang until something kills it? Unattended

# recording depends on the answer -- a job that never exits needs a hard cap.
