- Add skip_merge flag for N_m3u8DL-RE to prevent duplicate init data
- Pass content_keys to N_m3u8DL-RE for internal decryption handling
- Use shutil.move() instead of manual merge when skip_merge is True
- Skip manual decryption when N_m3u8DL-RE handles it internally
Fixes audio corruption ("Box 'OG 2' size is too large") when using N_m3u8DL-RE with DASH manifests that have SegmentBase init data. The init segment was being written twice: once by N_m3u8DL-RE during its internal merge, and again by dash.py during post-processing.
- Add CENC namespace support for kid/default_KID attributes
- Detect and replace placeholder/test KIDs in Widevine PSSH:
- All zeros (key rotation default)
- Sequential 0x00-0x0f pattern
- Shaka Packager test pattern
- Change DRM init condition from `not track.drm` to `init_data` to ensure DRM is always re-initialized from init segments
Fixes issue where Widevine PSSH contains placeholder KIDs while the real KID is only in ContentProtection default_KID attributes.
Add PlayReady PSSH/KID extraction from track and init data with CDM-aware ordering. When PlayReady CDM is selected, tries PlayReady first then falls back to Widevine. When Widevine CDM is selected (default), tries Widevine first then falls back to PlayReady.
Add support for BaseURL elements at the AdaptationSet level per DASH spec. The URL resolution chain now properly follows: MPD → Period → AdaptationSet → Representation.
Fix off-by-one error in SegmentTemplate segment enumeration when startNumber is 0. Previously, the code would request one extra segment beyond what exists, causing 404 errors on the final segment.
The issue was that end_number was calculated as a segment count via math.ceil(), but then used incorrectly with range(start_number, end_number + 1), treating it as both a count and an inclusive endpoint.
Changed to explicitly calculate segment_count first, then derive end_number as: start_number + segment_count - 1
Example:
- Duration: 3540.996s, segment duration: 4s
- Before: segments 0-886 (887 segments) - segment 886 doesn't exist
- After: segments 0-885 (886 segments) - correct
