AI Summary
A major feature release introducing quantizer support, expanding the Quality class, and deprecating the bitrate field.
Key Highlights
- Added quantizer support for encoders, enabling constant-quality encoding.
- Expanded the Quality class to accept arbitrary levels, specify bitrate modes, and concrete per-codec quantizer levels.
- Deprecated bitrate fields across the API in favor of the new quality field.
- Fixed video/audio decoders not being closed in certain error situations.
Breaking Changes
- Deprecated 'bitrate' fields across the API; use the new 'quality' field instead.
New Features
- Quantizer support for encoders with automatic mode selection for subjective qualities.
- Expanded Quality class capabilities (arbitrary quality levels, bitrate specification, concrete quantizer levels).
- Adjusted @mediabunny/server to properly forward quantizer settings to libavcodec.
Full Release Notes
- Added quantizer support for encoders, enabling constant-quality encoding. Quantizer mode is used automatically if you use subjective qualities; no code changes needed. (#448) - Expanded the `Quality` class: Can now take in an arbitrary quality level, specify bitrate and bitrate mode, and specify a concrete per-codec quantizer level - Adjusted `@mediabunny/server` to properly forward quantizer settings to libavcodec - Deprecated `bitrate` fields all across the API; use the new `quality` field instead - Fixed video/audio decoders not being closed in certain error situations (#446) - Fixed promises hanging indefinitely sometimes when calling Input.dispose() - Improved encoder error handling to reduce "Sample wasn't closed" warnings - Fixed ISOBMFF muxer not labeling video tracks as containing an alpha track (for example, with ProRes 4444) (#450)
