Weekly pre-release

on GitHub

Improvements

• More API documentation
• Better error reporting
• Nicer error messages in the cli application
• Explicit validation of the encoder configuration
• The input Frame type can be expressed
• Added cargo-fuzz support and documented its usage
• Better rate-control support
• Two-pass rate-control support
• Additional speedups over all the speed levels on x86_64

Changes

• Tiles are now expressed in linear units (before were log2-units)
• The for color config enum variants now use the AV1 spec names
• The C-API is now part of the main repo, use cargo-c to build it
• send_frame can consume bare Frames

Fixes

• Desync caused by a discrepancy of what would be the tile dimension and the loop restoration filter dimension when using certain tile sizes.
