I-IAL9000/shrinkerr v0.7.4

on GitHub

Added

• Language metadata for UDF-only Blu-ray ISOs (closes v0.7.3's known limitation). bsdtar/libarchive 3.7.2 silently returns empty on UDF 2.50+ BD ISOs, so v0.7.1's fallback didn't actually help the discs it was added for. v0.7.4 adds a tier-3 fallback using libbluray directly via Python ctypes — the same library ffmpeg already uses for bluray: protocol encoding, so we know it can read these ISOs. Opens the ISO with bd_open, walks titles → clips → streams, reads per-track lang[4] from BLURAY_STREAM_INFO. ISO 639-2 codes normalized T→B form (fra→fre, deu→ger, etc.) to match the rest of the codebase. Adds libbluray-bin to both Dockerfiles. Verified against Elephant (2003) UDF-only BD ISO: audio: [fre, eng], subtitle: [fre, fre].
