- Parse #EXTVLCOPT:program=N from M3U playlists (both full and streaming parsers, per channel, strict mode) and store it on playlist items - Transcode multi-program MPEG-TS streams by mapping only the selected program's first video and audio stream (DVB teletext/subtitles in the program otherwise make FFmpeg fail to produce HLS) - Optional per-source "zap before streaming" with configurable delay: POST /api/openwebif/zap takes sourceId + streamId, requires an enabled, zap-enabled M3U source containing that channel, derives the receiver from the configured source URL (never from the client), validates the Enigma2 service reference, uses a timeout without redirects and does not echo the receiver response - Live TV: Stop button, and stop playback when leaving the page - Tests for ordinary and program-tagged playlists and the zap endpoint Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
