Release Notes

In addition to some perfromance improvements with the load-scenes command, this release of PySceneDetect includes a significant amount of bugfixes. Thanks to everyone who contributed to the release, including those who filed bug reports and helped with debugging!

Program Changes:

• [bugfix] Fix crash for some WebM videos when using save-images with --backend pyav #355
• [bugfix] Correct --duration and --end for presentation time when specified as frame numbers #341
• [bugfix] Progress bar now has correct frame accounting when --duration or --end are set #341
• [bugfix] Only allow load-scenes to be specified once, and disallow with other detect-* commands #347
• [bugfix] Disallow -s/--start being larger than -e/--end for the time command
• [bugfix] Fix detect-adaptive not respecting --min-scene-len for the first scene
• [general] Comma-separated timecode list is now only printed when the list-scenes command is specified #356
• [general] Several changes to [list-scenes] config file options:
  • Add display-scenes and display-cuts options to control output
  • Add cut-format to control formatting of cut points #349
    • Valid values: frames, timecode, seconds
• [general] Increase progress bar indent to improve visibility and visual alignment
• [improvement] The s suffix for setting timecode values in seconds is no longer required (values without decimal places are still interpreted as frame numbers)
• [improvement] load-scenes now skips detection, generating output much faster #347 (thanks @wjs018 for the initial implementation)

API Changes:

• [bugfix] Fix AttributeError thrown when accessing aspect_ratio on certain videos using VideoStreamAv #355
• [bugfix] Fix circular imports due to partially initialized module for some development environments #350
• [bugfix] Fix SceneManager.detect_scenes warning when duration or end_time are specified as timecode strings #346
• [bugfix] Ensure correct string conversion behavior for FrameTimecode when rounding is enabled #354
• [bugfix] Fix AdaptiveDetector not respecting min_scene_len for the first scene
• [feature] Add output_dir argument to split_video_ffmpeg and split_video_mkvmerge functions to set output directory #298
• [feature] Add formatter argument to split_video_ffmpeg to allow formatting filenames via callback [#359](https://github.com/
  /issues/359)
• [general] The frame_img argument to SceneDetector.process_frame() is now required
• [general] Remove TimecodeValue from scenedetect.frame_timecode (use typing.Union[int, float, str])
• [general] Remove MotionDetector and scenedetect.detectors.motion_detector module (will be reintroduced after SceneDetector interface is stable)
• [improvement] scenedetect.stats_manager module improvements:
  • The StatsManager.register_metrics() method no longer throws any exceptions
  • Add StatsManager.metric_keys property to query registered metric keys
  • Deprecate FrameMetricRegistered and FrameMetricNotRegistered exceptions (no longer used)
• [improvement] When converting strings representing seconds to FrameTimecode, the s suffix is now optional, and whitespace is ignored (note that values without decimal places are still interpreted as frame numbers)
• [improvement] The VideoCaptureAdapter in scenedetect.backends.opencv now attempts to report duration if known
