2017-01-04 v1.7.0 "Mandarin Duck" This release focused on high bit depth performance (10/12 bit) and vp9 encoding improvements. - Upgrading: This release is ABI incompatible due to new vp9 encoder features. Frame parallel decoding for vp9 has been removed. - Enhancements: vp9 encoding supports additional threads with --row-mt. This can be greater than the number of tiles. Two new vp9 encoder options have been added: --corpus-complexity --tune-content=film Additional tooling for respecting the vp9 "level" profiles has been added. - Bug fixes: A variety of fuzzing issues. vp8 threading fix for ARM. Codec control VP9_SET_SKIP_LOOP_FILTER fixed. Reject invalid multi resolution configurations.
