Dec 1, 2024December 2024 monthly summary for zyedidia/media: Focus on correctness, compliance, and stability of AC-4 audio handling. Key deliverable this month was a bug fix to channel count calculation that ensures LFE is always included in the total, aligning with Dolby specifications and addressing an ETSI-level discrepancy in interpreting fullband objects. The change reduces miscount risks downstream and improves interoperability across encoding/decoding paths.
