KWIVER v1.8.0 Release Notes

This is a minor release of KWIVER that provides both new functionality and fixes
over the previous v1.7.0 release.

Updates

KWIVER

  • Adopted C++17.

  • Added setup_KWIVER.ps1.

  • Added the MSVC 2022 compiler as a case in our CMake logic.

Vital

Vital Algo

  • Added API for algorithms to find nearest neighbor to a set of point in 3D.

  • Expanded the pointcloud_io API to include the ability to load point cloud data

  • Added option to open file given to metadata_map_io in binary mode.

  • Added buffered_metadata_filter.

Vital Types

  • Added new pointcloud type to hold point cloud data

  • Added VITAL_META_UNIX_TIMESTAMP_SOURCE, VITAL_META_VIDEO_DATA_STREAM_SYNCHRONOUS.

  • Removed VITAL_META_ICING_DETECTED.

  • Added equality operators for metadata_item.

  • Added metadata_[io]stream.

Vital Util

  • Added support for different text codecs (ASCII, UTF-8, etc).

  • Added threeway_compare().

Arrows

  • Passed a constant seed to the random point generator used by several tests to
    prevent occasional random failure.

Arrows: Core

  • Implemented a general-purpose CSV reader and writer.

  • Prevent UV coordinates from going to NaN for degenerate triangles in uv_unwrap_mesh.

  • Fixed race condition in close_loops_exhaustive that could result in a crash
    when matching and merging feature tracks.

  • Fixed undefined behavior leading to a crash in track_features_core when the
    track set remained empty after the first frame.

  • Fixed an incorrect cast of a geo_point to double in derive_metadata.

Arrows: FFmpeg

  • Added support for FFmpeg 5.1.2.

  • Added basic configuration options to ffmpeg_video_output.

  • Added CUVID video decoding/encoding support.

  • Added support in ffmpeg_video_output for non-RGB24 input images.

  • Fixed many bugs with timestamps.

  • Implemented direct copying of video stream packets from input to output.

  • Improved robustness against invalid input data.

  • Added config options to ffmpeg_video_input to ignore the video or KLV streams.

  • Properly handle MISP nanosecond timestamps.

  • Added padding to end of image memory to avoid segfaults.

  • Improved the search paths to find an FFmpeg installation.

  • Fixed alignment between KLV packets and frames when reading and writing.

  • Limit total amount of past KLV maintained in memory.

  • Added new synthetic test videos.

  • Added derivation of KLV synchronicity from stream and packet characteristics.

  • Made initial probing logic more persistent.

Arrows: KLV

  • Implemented ST1107.

  • Updated ST0903 implementation to version 6.

  • Implemented the BOOLEAN, UINT, and RLE APAs in ST1303.

  • Adjusted tag number requirements of ST0806.

  • Changed data type of EG0104 Episode Number to string.

  • Implemented configuration of KLV muxing update rates.

  • Modified interface to use pointers when reading/writing instead of
    std::vector iterators.

  • Used std::nullopt to indicate no ST0601 control command timestamp instead of 0.

  • Used std::chrono to better express MISP timestamps.

  • Changed type of ST0601 Waypoint Record bitfield.

  • Added detailed length constraint information.

  • Fixed bug when calculating length of ST0601 Airbase Locations.

  • Fixed bug which prevented detection of some too-long KLV packet lengths.

  • Added apply_child_klv and update_klv metadata filters.

  • Implemented CRC-8-CCITT checksum.

  • Fixed bug when ST0903 local set packs fail to parse.

  • Made headers public which were included by other public headers.

  • Improved descriptions of formats.

  • Implemented handling of different string encodings.

  • Fixed possible out-of-bounds memory read leading to crash when KLV parsing
    fails.

  • Fixed bug in KLV packet reader which failed to check if the packet's length
    was larger than the available number of input bytes.

  • Fixed bug in ST0601 view domain writer which would not write the length of
    the final field.

  • Added a missing type to the ST0601 KLV JSON exporter.

Arrows: PDAL

  • Added implementation of the load API to pointcloud_io to load point data via the PDAL library

Arrows: Serialize JSON

  • Fixed bug when loading a KLV local set item with a null value.

  • Fixed bug preventing the proper loading of strings with embedded null ('\0')
    characters.

  • Increased the precision of exported floating point values.

  • Added a configuration option to compress JSON on output.

Arrows: Zlib

  • Added this arrow with bytestream_compressor functionality.

KwiverSys

  • Made compiling regular expression thread-safe.

Applets

Applets: bundle adjustment tool

  • Added an implementation bundle adjustment (BA) applet that optimizes a set of
    cameras given multiple 3D-2D point correspondences.

Applets: transcode

  • Fixed a bug in which metadata was erroneously written after each frame,
    instead of before.

Applets: dump-klv

  • Added an option to use multithreading when dumping frame images.

  • Removed early exit when no KLV stream is found.

Applets: compare-klv

  • Added this applet.

Python:

  • Removed the custom pybind11.h header file since the current version of
    pybind11 now handles cases where the GIL is acquired via the
    PyGILState_* API.
