v1.5.0 — Smarter Bitrate Control
What's new
🎚️ BITRATE_CAP — encode at source bitrate without upscaling
A new BITRATE_CAP environment variable lets you set a maximum bitrate ceiling. Each book is encoded at whichever is lower — its original source bitrate or your cap. Books already below the cap are left at their native bitrate instead of being upscaled.
Example with BITRATE_CAP=120k:
- A book at 256k → encoded at 120k
- A book at 60k → encoded at 60k
environment:
BITRATE_CAP: "120k"Note: When BITRATE_CAP is set it takes full precedence over BITRATE.
