DVR-Scan v1.4.1

Release Notes

This release includes fixes for incorrect event start/end times when using frame skipping, and improvements to the bounding box overlays.

Important: Aside from critical bugfixes, DVR-Scan 1.4 is the last version supporting Python 2.7. Starting from v1.5, the new minimum supported Python version will be 3.6 3.7 (see #83 for details).

Python users can install via pip:

pip install --upgrade dvr-scan[opencv]

Builds for Windows (installer + portable .zip) are available below.

Changelog

• [bugfix] Event start times are now correctly calculated when using -fs/--frame-skip (#68, #70)
  • Note that event start/end times may still be off by how many frames are skipped due to loss of context with respect to frame-accurate motion detection
• [bugfix] Event end times now take into account the number of skipped frames if -fs/--frame-skip if specified (e.g. it is assumed all skipped frames contained motion)
• [bugfix] Bounding box smoothing now takes into account -fs/--frame-skip (#31)
• [bugfix] Bounding boxes now cover all frames with motion (#31)
  • In v1.4 only the frames after -l/--min-event-length frames had passed were covered

Known Issues

• Variable framerate videos (VFR) are not fully supported, and will yield incorrect timestamps (#20)
• Using -st/--start-time will yield incorrect results
