This is a major upgrade from 3.x to 4.x.
Changelog from versions 3.4.1--4.5.1 can be found here:
https://github.com/opencv/opencv/wiki/ChangeLog
Note: this has explicitely not been added as a new graphics/opencv4 port, but replaces the
previous graphics/opencv[3] port. Again, to improve maintainability by not giving ports
the option to pick the "wrong one" - this leads however to some abandoned ports being
broken.
The port has been greatly simplified:
* graphics/opencv-core which existed to enable ffmpeg to depend on opencv, and vice versa
has been removed. ffmpeg no longer can depend on opencv.
* graphics/py-opencv has been integrated into graphics/opencv, the default versions python
bindings will be built unless the PYTHON option is explicitely turned off.
* graphics/opencv-java has been integrated into graphics/opencv -- it is off by default,
but can be enabled by toggling the JAVA option -- there are no consumers in the tree,
so that option might go away in the future.
* All the previous options have been removed and replaced by a (hopefully) sane set of
dependencies that make the port and package most usable for the majority of consumers.
- Please let me know if you think there are better defaults (i.e. anything that is missing,
or something that should not be dependet on).
- If you think something should be added or removed, please open a bug report.
- If you think something should be added as an optional dependency, please open a
bug report (with a good reason [tm]).
The depending ports have been updated to work against opencv4, or marked broken.
* Ports broken:
- graphics/rubygem-objectdetect: OpenCV4 no longer ships opencv-1.0 API
- graphics/p5-Image-ObjectDetect: OpenCV4 no longer ships opencv-1.0 API
- graphics/gimp-gmic-plugin: OpenCV4 no longer ships opencv-1.0 API
* Backports:
- misc/visp: dfa7e4bd47
- multimedia/zart: 6ca1964690,
d3a2931b1a
* Others:
- misc/actiona: switch to pkgconfig 'opencv4'
- multimedia/libav: drop opencv support
- misc/darknet: already failed to build prior to the upgrade
- math/saga: remove patching added to work against opencv3
