Version 0.12.2

  • Enable threading for ffmpeg decoder, should greatly improve speed

Version 0.12.0

  • [Breaking] Move VideoDetails struct from y4m module to decoder module, since it is not specific to y4m
  • Add support for Ffmpeg decoder (requires Cargo ffmpeg feature, disabled by default)

Version 0.11.0

  • Add support for Vapoursynth decoder (requires Cargo vapoursynth feature, disabled by default)
  • Breaking change required to add a wrapper enum defining which decoder is being used

Version 0.10.0

  • Bump rav1e dependency to 0.7

Version 0.9.0

  • Bump y4m dependency to 0.8

Version 0.8.1

  • Finally release a new version because we can depend on rav1e 0.6.1

Version 0.8.0

  • Upgrade clap to 4.0
  • Add frame limit arg to API
  • [Breaking] Change progress_callback to take a &dyn Fn
  • Misc improvements including some speedups from rav1e
  • Update to Rust edition 2021

Version 0.7.2

  • Bump to the final release of rav1e 0.5
  • Bump other dependencies to latest versions
  • Fix another inconsistency with rav1e's scene detection
  • Improve precision of FPS calculation

Version 0.7.1

  • Fix an inconsistency with how rav1e's scene detection works
  • Fix some CLI help text

Version 0.7.0

  • Bump rav1e dependency to 0.5-beta.2, which brings a new, improved scenechange algorithm. Medium is equivalent to the old slow level, but with improvements. The fast level also has improvements. The new slow level is a new algorithm with a higher accuracy than the previous two algorithms.
  • The --fast-mode CLI argument is removed in favor of a --speed or -s argument, which takes a 0, 1, or 2 (for slow, medium, or fast). The default is 0 for slow.

Version 0.6.0

  • Bump rav1e dependency to 0.5. This should bring significant performance improvements, but may cause breaking changes.

Version 0.5.0

  • Bump rav1e dependency to 0.4
  • Expose new_detector and detect_scene_changes since these may be useful in some situations to use directly

Version 0.4.2

  • Fix compilation on non-x86 targets
  • Bump various dependencies

Version 0.4.1

  • Improve performance and memory usage

Version 0.4.0

  • [Breaking, New Feature] detect_scene_changes returns a DetectionOptions struct, which includes the list of scenecut frames, and the total count of frames in the video. The CLI output will reflect this as well.
  • [Breaking] Replace the default algorithm with an 8x8-block cost-based algorithm. This is more accurate in many cases.
  • [Breaking] As a result of the above change, now requires nasm for compilation. No action is needed if you use a prebuilt binary.
  • [Breaking] Replace the use_chroma option with a fast_analysis option. The new name is more accurate, as the updated algorithm will always analyze only the luma plane.
  • [Breaking] Move the progress_callback parameter from DetectionOptions to detect_scene_changes, since it only applies to that interface.
  • [New Feature] Expose the SceneChangeDetector struct, which allows going frame-by-frame to analyze a clip. Needed for some use cases. detect_scene_changes is the simpler, preferred interface.
  • The library for inputting frame data has been replaced with one that matches rav1e.
  • Simplify/optimize some internal code.

Version 0.3.0

  • [Breaking, New Feature] Add the ability to pass a progress_callback function to the DetectionOptions.

Version 0.2.0

  • [Breaking] Update y4m dependency to 0.5

Version 0.1.0

  • Initial release
