Migrating to Worker v2.7

Breaking Changes

Worker 2.7 deprecates the corruptness_check.corruption_threshold configuration option. The value is no longer used and Lightly Worker will abort if it is set to a non-default value. The option was used to remove video frames with decoding artefacts, please migrate to uniformRowRatio metadata instead. The new method was designed to yield fewer false positives and offers a more systematic approach to removing video frames.
