PySceneDetect v0.5.6

Release Notes

• New detection algorithm: detect-adaptive which works similar to detect-content, but with reduced false negatives during fast camera movement (thanks @scarwire and @wjs018)
• Images generated by save-images can now be resized via the command line
• Statsfiles now work properly with detect-threshold
• Removed the -p/--min-percent option from detect-threshold
• Add new option -l/--luma-only to detect-content/detect-adaptive to only consider brightness channel (useful for greyscale videos)

Changelog

• [feature] New adaptive content detector algorithm detect-adaptive (#153, thanks @scarwire and @wjs018)
• [feature] Images generated with the save-images command (scene_manager.save_images() function in the Python API) can now be scaled or resized (#160 and PR #203, thanks @wjs018)
  • Images can be resized by a constant scaling factory using -s/--scale (e.g. --scale 0.5 shrinks the height/width by half)
  • Images can be resized to a specified height (-h/--height) and/or width (-w/--width), in pixels; if only one is specified, the aspect ratio of the original video is kept
• [api] Calling seek() on a VideoManager will now respect the end time if set
• [api] The split_video_ functions now return the exit code of invoking ffmpeg or mkvmerge (#209, thanks @AdrienLF)
• [api] Removed the min_percent argument from ThresholdDetector as was not providing any performance benefit for the majority of use cases (#178)
• [bugfix] The detect-threshold command now works properly with a statsfile (#211, thanks @jeremymeyers)
• [bugfix] Fixed crash due to unhandled TypeError exception when using non-PyPI OpenCV packages from certain Linux distributions (#220)
• [bugfix] A warning is now displayed for videos which may not be decoded correctly, esp. VP9 (#86, thanks @wjs018)
• [api] A named logger is now used for both API and CLI logging instead of the root logger (#205)

Known Issues

• Variable framerate videos (VFR) are not fully supported, and will yield incorrect timestamps (#168)
• The -l/--add-last-scene option in detect-threshold cannot be disabled
• Image sequences or URL inputs are not supported by the save-images or split-video commands (in v0.6 save-images works with image sequences)
• Due to the use of truncation for frame number calculation, FrameTimecode objects may be off-by-one when constructed using a float value (#268, fixed in v0.6)
