Add unshackle.core.cdm.detect helpers to classify CDMs consistently across local and remote backends.
- Add is_playready_cdm/is_widevine_cdm for DRM selection across pyplayready, pywidevine, and wrappers
- Add is_remote_cdm/is_local_cdm/cdm_location so services can branch on CDM execution location
- Switch core DASH/HLS parsing, track DRM selection, and dl CDM switching away from brittle isinstance/DecryptLabs-only checks
- Make unshackle.core.cdm import-light via lazy __getattr__ so optional CDM deps are only imported when needed
- Parse init section byterange offset as int to avoid string arithmetic bugs
- Wrap MonaLisa licensing in the same progress + error handling flow as Widevine/PlayReady
- Add a small helper to move N_m3u8DL-RE final outputs into the expected temp path (preserve actual suffix) and keep subtitle codec consistent with the produced file.
- Skip generic HLS segment merging when N_m3u8DL-RE is in use to avoid mixing in sidecar files and reduce Windows file-lock issues.
- Harden segmented WebVTT merging to avoid IndexError when caption segment indexes exceed the provided duration list.
- Add MonaLisaCDM class wrapping wasmtime for key extraction
- Add MonaLisa DRM class with decrypt_segment() for per-segment decryption
- Display Content ID and keys in download output (matching Widevine/PlayReady)
- Add wasmtime dependency for WASM module execution
HLS: Filter segment keys by CDM type during aria2c merge phase to prevent incorrect Widevine selection when using PlayReady-only CDMs. The merge phase now uses filter_keys_for_cdm() before get_supported_key(), matching the pattern used in initial licensing.
DASH: Extend PlayReady CDM detection to include remote CDMs with is_playready attribute, not just native PlayReadyCdm instances. This ensures correct DRM extraction order from init_data when using remote PlayReady CDMs.
Session keys from master playlists often contain PSSHs with multiple KIDs covering all tracks, causing licensing to return keys for wrong KIDs.
Changes:
- Unified DRM licensing logic for all downloaders
- Prefer media playlist EXT-X-KEY tags which contain track-specific KIDs
- Add filter_keys_for_cdm() to select keys matching configured CDM type
- Add get_track_kid_from_init() to extract KID from init segment with fallback to drm.kid from PSSH
- Track initial_drm_key to prevent double-licensing on first segment
- Simplify n_m3u8dl_re block to reuse common licensing flow
- Use strict PlayReady keyformat matching via PR_PSSH.SYSTEM_ID URN instead of loose substring match
- Fix PlayReady keyformat comparisons that incorrectly compared strings to PlayReadyCdm class
- Fix byterange header format in get_track_kid_from_init() to use HLS.calculate_byte_range()
Also fixes PlayReady keyformat matching in:
- unshackle/core/tracks/track.py
- unshackle/core/drm/playready.py
Fixes download failures where track_kid was null or mismatched, causing wrong content keys to be obtained during PlayReady/Widevine licensing.
Fixed TypeError in calculate_byte_range where range_offset was a string instead of int. The byte_range.split("-")[0] returns a string, but the calculate_byte_range method expects fallback_offset parameter to be int.
