Hi, Adam, glad to hear! Please give it a try! I've just pushed a new version with workin video read/write. So this gives PDL now a video reader.
I have two questions for further development. 1. OpenCV is huge. Every method needs a C wrapper which needs a PP function. So, code generation is almost certainly a must. As you can see, some functions are already generated but this is more of a hack than. My needs and time are limited at the moment, so I may not do great developments beyond what is present in the near future. Ideally, a parser for hpp files would generate wrapper code and a PP api. I guess this can be done for a large subset of OpenCV methods with tweaks here and there. I guess the Inline::CPP parser could be a starting point? 2. The build system is a hack. The cw directory contains C++ wrappers that use cmake and are partly generated using Makefile.pm. So, cmake needs to run successfully and you need to make install so that PDL::OpenCV can find the shared object. I think the PDL::OpenCV modules should link directly against the cw/build directory avoiding the install step. If cmake is not successfully finding libs, I guess using something like ccmake to set paths etc. updating the cmake cache after code generation should work in many situations. I guess in the end an Alien::OpenCV module should take care of the C wrapper, which is somehow conflicting with code generation. Again, I may or may not be able to significantly change the current behaviour. I suppose substituting Mat by UMat in the wrapper could provide seamless OpenCL integration? Anyone has experience with this? Looking forward to your feedback. Ingo On 4/19/22 15:54, Adam Russell wrote:
Great work! Thank you for doing this. I was recently Looking to use OpenCV via Perl and hit a bit of a wall. I am looking forward to trying this.

Please read the INSTALL document. It is a two step process. It is basic but works.
