Implements cross-platform font discovery and intelligent fallback system for ASS/SSA subtitle rendering on Linux/macOS systems.
Windows support has not been tested
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
HDR10/PQ detection now includes:
- PQ (most common)
- SMPTE ST 2084 (CICP value 16)
- BT.2100
- BT.2020-10
- smpte2084 (lowercase variant)
HLG detection now includes:
- HLG
- Hybrid Log-Gamma
- ARIB STD-B67 (CICP value 18)
- arib-std-b67 (lowercase variant)
Hybrid DV+HDR10 detection:
- Now checks full hdr_format field for both "Dolby Vision" AND
("HDR10" OR "SMPTE ST 2086")
- Properly generates filenames like "Movie.2160p.DV HDR H.265.mkv"
- MediaInfo reports: "Dolby Vision / SMPTE ST 2086, HDR10 compatible"
Also adds null safety for transfer characteristics to prevent errors when the field is None.
Add new CustomRemoteCDM class to support custom CDM API providers with maximum configurability through YAML configuration alone. This addresses GitHub issue #26 by enabling integration with third-party CDM APIs.
Implements a complete structured logging system for troubleshooting and service development.
Features:
- Binary toggle via --debug flag or debug: true in config
- JSON Lines (.jsonl) format for easy parsing and analysis
- Comprehensive logging of all operations:
* Session info (version, platform, Python version)
* CLI parameters and service configuration
* CDM details (Widevine/PlayReady, security levels)
* Authentication status
* Title and track metadata
* DRM operations (PSSH, KIDs, license requests)
* Vault queries with key retrieval
* Full error traces with context
- Configurable key logging via debug_keys option
- Smart redaction (passwords, tokens, cookies always redacted)
- Error logging for all critical operations:
* Authentication failures
* Title fetching errors
* Track retrieval errors
* License request failures (Widevine & PlayReady)
* Vault operation errors
- Removed old text logging system
Revert the warnings filter added in 2d5e807 as it didn't work as expected to suppress the tinycss SyntaxWarning. Also fix isort order in prd.py for pyplayready imports.
New --exact-lang CLI flag that enables exact language code matching instead of fuzzy matching. This allows users to get specific regional variants without matching all related variants.
Examples:
- `-l es-419` normally matches all Spanish (es-ES, es-419, es-MX)
- `-l es-419 --exact-lang` matches ONLY es-419 (Latin American Spanish)
Fixes language detection issue where specific variants like es-419 (Latin American Spanish) would match all Spanish variants instead of just close regional variants.
- Add pysubs2 as default conversion method for 'auto' mode
- Add support for MicroDVD (.sub), MPL2 (.mpl2), and TMP (.tmp) formats
- Implement convert_with_pysubs2() method with fallback to standard conversion
- Update from_mime() to handle new subtitle format types
- Map all supported formats to pysubs2 format identifiers
- Update docstrings to reflect new capabilities
Move warnings.filterwarnings() to the very top of __main__.py before any
other imports to ensure it takes effect before tinycss is loaded during
module discovery. This fixes the SyntaxWarning from the unmaintained
tinycss package (a dependency of subby).
refs #20
- Upgrade pyplayready from >=0.6.0 to >=0.6.3
- Upgrade subby to 0.3.23 (commit 5a925c36) for lxml 6.x compatibility
- Upgrade lxml from 5.4.0 to 6.0.2
- Fix pyplayready exception imports to use root-level imports (compatible with both 0.6.0 and 0.6.3)
- Suppress SyntaxWarning from unmaintained tinycss dependency
The pyplayready package changed its API between versions:
- v0.6.0: exceptions in pyplayready.exceptions module
- v0.6.3: exceptions in pyplayready.misc.exceptions module
Using root-level imports (from pyplayready import ...) works with both versions.
ref #20
Very early dev work, more changes will be active in this branch.
- Implement download queue management and worker system
- Add OpenAPI/Swagger documentation
