| # | Requirement | Acceptance Criteria | |---|-------------|---------------------| | FR‑13 | Output must be CMAF‑compatible (fragment duration 2 s, moof/mdat alignment). | MP4Box validation passes; playback on Safari & Chrome works. | | FR‑14 | Inject ATID‑260 metadata block (custom udta atom) with fields: ATID, RM, HD, TODAY, MIN, REPACK. | ffprobe shows custom atom with correct values. | | FR‑15 | Generate a SHA‑256 checksum of the final file and store it in the metadata DB. | Checksum matches after copy to another bucket. | | FR‑16 | Preserve time‑code continuity (no timestamp jumps). | Playback shows monotonic PTS; ffprobe timestamps are sequential. | | FR‑17 | Optionally create HLS/DASH manifests as side‑car files. | Manifest lists a single rendition; test playback via Shaka Player succeeds. |
