Add support for BaseURL elements at the AdaptationSet level per DASH spec. The URL resolution chain now properly follows: MPD → Period → AdaptationSet → Representation.
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.
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
