about

nx_ts_probe.nx -- Rung 1 of the sovereign MPEG-TS -> fMP4 remuxer. Parses an MPEG-TS file (188-byte packets), reads PAT -> PMT -> elementary-stream table, identifies the video PID + codec, reassembles the video PES into an Annex-B elementary stream, and scans it for NAL units (SPS=7 / PPS=8 / IDR=5). Reports what it finds so we can confirm H.264 before building the MP4 muxer. NishiLang only, no ffmpeg. Usage: nx_ts_probe <file.ts> (default = first recording in the vid index). license_tier: ORIGINAL
