1.7.1
Release: 1.7.1879b9d94 · ·Release 1.7.1 - 21.07.2025 INCOMPATIBLE CHANGES - dv-sdk/log.hpp: dv::Logger together with DV_MODULE_MULTI_THREAD_SAFE was not working correctly on all platforms. An alternative approach for thread-safety has been implemented, by simply disallowing log-append operations if the DV_MODULE_MULTI_THREAD_SAFE define is set to 1. This was only used internally and should have no user impact. BUG FIXES - Cameras: fix usb control transfer in notification (from dv-processing). - Cameras: adapt to logger changes (from dv-processing).

1.7.0
Release: 1.7.097f0210b · ·Release 1.7.0 - 15.07.2025 INCOMPATIBLE CHANGES Compatibility with version 2.0 of the dv-processing library requires recompilation of any custom modules. This is automatically enforced, old modules will not load. CMake: renamed options with DVR_ prefix to prevent collisions, ie. DVR_ENABLE_TCMALLOC. Build: raised minimum compiler versions to GCC 13, clang 18, XCode 16 or MSVC 19.39 (Visual Studio 2022 17.9). Build: raised minimum dependency versions to boost 1.80, fmt 9.1.0, dv-processing 2.0. cstring/cvector: removed own re-implementations of std::string (dv::cstring) and std::vector (dv::cvector), the standard containers are used instead. You will need to recompile. dv::runtime_assert(): changed to use functors, allowing guaranteed removal on non-debug builds. fmt: removed custom std::vector formatter, use the official one from fmt instead. Ubuntu: dropped support for Bionic 18.04. libcaer: removed as a dependency, no longer used. dv::EventColor: GREEN component has been split into GREEN1 and GREEN2. New camera modules for DVS128, DAVIS, DVXplorer and DVXplorer Mini / Micro. Some configuration switches and names have changed. Field 'tsOffset' in output information has been removed as it is no longer required due to proper multi-camera time synchronization support, all cameras now have the same real-time offset. This extra information will also not be recoreded in files anymore, old files remain unchanged. Field 'colorFilter' in event output information has been replaced by new field 'eventsPixelArrangement', which is directly compatible with new dv::EventColor. Old recordings with the old name will still work. Support for eDVS, DVS132S, Samsung EVK and some old experimental DAVIS models has been dropped. All of these continue to be supported by libcaer if needed, and other than the eDVS none of them have been commercially sold by iniVation. NEW FEATURES New camera modules for DVS128, DAVIS, DVXplorer and DVXplorer Mini / Micro. These use the new dv-processing 2.0 APIs for device access. Some configuration switches and names have changed, controls are often simpler to use. Support for eDVS, DVS132S, Samsung EVK and some old experimental DAVIS models has been dropped. A selection of notable new features: synchronization of an arbitrary number of cameras supported via new 'syncWith' configuration, for details see our documentation: https://docs.inivation.com/hardware/hardware-advanced-usage/external-camera-sync.html#dv DVS128/DAVIS: simplified biasing with clearer names DVXplorer: allow finer bias control for ON/OFF contrast thresholds For DVXplorer Mini/Micro only: a firmware upgrade (v10) is required for compatibility. Frame Color Calibration: added new module to perform color calibration for RGB frames. Ubuntu: added support for Noble 24.04. Boost: added compatibility with latest boost::ASIO releases. Aravis (MVCamera): added compatibility with latest Aravis 0.9 release series. fmt::format: added formatters for cv::Mat, cv::Size, cv::Point and cv::Rect.

1.5.2
Release: 1.5.2d0abd90a · ·Release 1.5.2 - 11.04.2022 NEW FEATURES - Frames / Events: frame and event outputs will now check that the respective data has the proper size/coordinates to be sent out via an output. Frames will always check this, events only in DEBUG mode due to performance. - Debug mode: use dv-processing's dv::DEBUG_ENABLED and dv::runtime_assert() debug functionality in place of NDEBUG and assert() macros. - DVXplorer: add constant, high eFPS readout modes (can dismiss events). BUG FIXES - Depend on dv-processing 1.4.0 for latest features. - Modules: require recompilation of all custom modules due to header changes. - Backwards compatibility: fix issue with DV_LIBRARIES not being defined in CMake, it is now always defined to be 'dv::sdk'. - Backwards compatibility: fix issues with 'dv-sdk/processing/*.hpp' includes. - Cameras: fix reset of buttons pressed while a module is stopped (issue #406). Release 1.5.1 - 25.02.2022 NEW FEATURES - DVXplorer: add new control of readout speed (eFPS). - DVXplorer: add new controls for custom fine bias adjustment. BUG FIXES - DV-SDK: fix several backwards compatibility issues with changes to header files due to dv-processing. - LiveStream/VideoOutput: fix compilation with FFMPEG 5.0. - DVXplorer: remove activity detection configuration. Release 1.5.0 - 14.02.2022 NEW FEATURES - DV-SDK: headers are compatible with usage together with the new dv-processing C++20 library. This will require recompilation of any custom modules! - Frames: frame type has a different API, is now fully based on OpenCV Mat. - Increased CMake requirements to 3.16, compiler to C++20, fmt to 7.1.3. - Deprecated dv-modules.cmake and the DV_MODULE_SETUP() function, instead use FIND_PACKAGE(dv 1.5.0) to import the 'dv::sdk' CMake target.

1.4.0
Release: 1.4.0099b5f13 · ·Release 1.4.0 - 20.01.2021 INCOMPATIBLE CHANGES - dv-runtime: the runtime does not have a default configuration file anymore that it will load/save the configuration to (issue #253). To load configuration from a file, explicitly pass the '-c <CONFIG_FILE>' command-line option. To save, set the "/system/config/saveFile" attribute to the path where you want to save the current configuration and then set "/system/config/writeSaveFile" to "true" to write the file (issue #295). GUI users won't have to do anything. The SystemD/OpenRC services will take care of resuming from saved configuration automatically as before. - dv-runtime: the command-line options for the dv-runtime binary have changed (issue #386): - removed -b0/1 (--background) option, runtime always executes in the foreground now. - removed -a0/1 (--allinterfaces) option, explicitly use '-i <IP>' option now to specify the interface to listen on, use '-i 0.0.0.0' to get the old behavior of listening on all interfaces. - removed -o configuration override, edit a configuration file and use '-c <CONFIG_FILE>' if you need to start with modified configuration. - added -i <IP> option, use this to specify the IP address where the runtime will listen for new connections (default '127.0.0.1'). - added -p <PORT> option, use this to specify the port where the runtime will listen for new connections (default '4040'). - added -l <LOG_FILE> option, to specify the path where to write the log file (default '$HOME/.dv-runtime.log'). - added -s0/1 (--systemservice), used for SystemD/OpenRC system service mode, should not be needed by normal users. - TCP server output: the default IP address to listen on is now the same as the dv-runtime's IP address, while the default port is now '0', meaning a random free port is chosen and then published in the configuration attribute. The GUI will show the actual port. You can also manually put in the value '7777' to get back the old behavior. NEW FEATURES - ConfigServer: can be started with port value of '0' (CLI '-p 0') to select a random port for listening to new connections, will print this as a log message for retrieval. - Modules: 'modulesSearchPath' is now initialized from the environment variable 'DV_MODULES_PATH'. - Unix Socket Output: added new module 'dv_output_net_socket' for Unix socket-based data output (issue #215). BUG FIXES - Undistort: improved efficiency of out-of-bounds pixels lookup. - DAVIS camera: the 'Exposure' configuration attribute is now read-only and not saved if 'AutoExposure' is enabled. - ConfigTree: report failures in opening configuration files for reading or writing. -
1.3.2
Release: 1.3.2a5495389 · ·Release 1.3.2 - 22.12.2020 INCOMPATIBLE CHANGES - Flip&Rotate: module renamed from 'dv_flip-rotate' to 'dv_flip_rotate' for consistent naming (issue #378). - Crop&Scale: changed cropping configuration attributes to allow easier specification of Region-of-Interest to cut out, set output frames position to 0,0; same as events output. - SDK utils.h: removed dv::findBool() and dv::findIfBool() functions that take two iterators, no significant advantages and no real users. Prefer std::vector variant. - SDK utils.h: dv::findBool() and dv::findIfBool() for std::vector have been renamed to dv::vectorContains() and dv::vectorContainsIf() respectively, to better reflect what they do and align naming with the other vector helper functions present in utils.h. NEW FEATURES - dv-control: command-line utility now supports setting strings that contain spaces ("test str ing"), empty string can also be set using "" (issue #375). - DVS Noise Filter: found hot-pixels are now saved in the string configuration attribute 'hotPixelList', from where they are loaded on module startup and configuration update (issue #341). Manual modification of the list is also possible. This keeps the list alive between restarts, such as when playing back a recording. - SDK event.hpp: new function for event inputs 'colorForEvent(evt)', determines the Bayer filter color for an event based on its address, returns WHITE for no filter/mono (issue #381). Example: auto color = inputs.getEventInput("events").colorForEvent(evt); - std::vector/dv::cvector/dv::cstring: added fmt::format formatter to format/log these types directly (issue #374). - dv::cvector: added convenience methods contains(), containsIf(), sortUnique(), remove() and removeIf() (issue #374). - SDK modules: improve thread safety for 'log' and 'config' module objects access (issue #373). Disabled by default, as it's only needed for modules that start extra threads of their own and access these objects from multiple of them. To enable, add the following define at the start of your modules' includes: #define DV_MODULE_MULTI_THREAD_SAFE 1 BUG FIXES - SDK API frame.hpp: fixed edge-case where size of backing pixels vector could be bigger than actual X*Y*CHAN (issue #370). - Device Discovery: improve log message on failure. - File Input, dv-filestat: fix error message on FileDataTable verification failure, allow FileDataTable with more than 1 million entries (issue #380). - dv-filestat: stricter verification of IOHeader/FileDataTable, print number of elements in FileDataTable (issue #380). - Windows: fix invalid UTF-8 strings being sent by runtime to clients/GUI (issue #385). - Crop&Scale: correctly support cropping frames with ROI information present (issue #378). - Flip&Rotate: correctly support rotating frames with ROI information present (issue #378). - Converter: better calculation of frame pixel values, based on libcaer, for conversion of AEDAT 2.0 files.
