according to

https://docs.opencv.org/4.x/db/d05/tutorial_config_reference.html

you can try to disable opencv's use of openexr (!) by using cmake option
WITH_OPENEXR=OFF and also disable all ffmpeg/gstreamer stuff too...

No, I simply copied the six OpenCV plugins from CinGG's git. I copied
them to .../bin/plugins/video/.
These were not being recognized though. I was using the build with
external ffmpeg 5 (--without-thirdparty); now that I tried the normal
CinGG build from git, I have no more problems and I have the OpenCV
plugins working.

Andrea, I will test this today after I get my GIT checkin done and see if I
have the same problem.
Do you mean you copied the filters from another run or did you actually
compile with the OpenCV downloaded from the website?

After a long time I tried to copy the OpenCV filters inside CinGG
(don't compile them while I compile CinGG). At startup they are not
loaded.

Re: [Cin] opencv build trim

[Andrew Randrianasulu via Cin]

on topic of opencv I instalked opencv 4.5.5 on termux and tried to build
cingg plugins against this.

most plugins worked with hack - but for some reason final link faild to add
opencv libs (no pkgconfig for them, it seems?) and so resulted plugins
aborted cin on load.


hack:

$ git diff thirdparty/Makefile plugins/Makefile
diff --git a/cinelerra-5.1/plugins/Makefile b/cinelerra-5.1/plugins/Makefile
index e6718432..cb3a10e8 100644

+OPENCV_OBJS := flowobj gaborobj moveobj stylizeobj findobj
 $(OPENCV_OBJS): opencv
 endif

err, not all changes...

puzzleobj failed to build anyway, so I commented it out.

may be on more standart Linux dynamuc/system build with this hack still
will work (produce usable plugins?)
