I was thinking about moving OpenCV build before ffmpeg (if enabled), so ffmpeg will get openCV plugin/filters too ..but not sure if any of them will be of any use.. just wild thought! > They are > expensive and complicated to build.

Plugins appear to be functional (at least like StylizeObject/Gabor, not sure how to make FindObject work? What exactly it tries to find?) will look for binary stuff (probably neural network training data?) I have old (2.4.10?) gphoto2 libs/includes, so I used little additional patch to get past build error. > > to get the 4.x.x version to work, you need to uncomment the: > #CFLAGS += -I$(opencv_prefix)/include/opencv4 > lines (two of them) in the opencv_build file before you run the build. > Before you this, you will first need to create a tarball > with both opencv and opencv_contrib in the build. > > By chance, I was actually getting set to try again on opencv 4.x.x since it > now is early in the month, > and I have a while to get it to build and to test it.

Yeah, some heavy stuff inside. But i was asking about non-opencv build, i think libzmpeg freaked out when saw -fsanitize=address in cflags ...and some thirdparty lib, too (liba52?) they scrolled way past my 1000 lines current terminal history :} > > > > On Fri, Nov 1, 2019 at 7:55 AM Andrew Randrianasulu <[email protected]> > wrote: > > > Hello! > > > > I tried to rebuild CinGG with OpenCV plugins, yet build failed like this: > > > > /dev/shm/tmp/cinelerra-goodguy-20191101/cinelerra-5.1/thirdparty/opencv/modules/videoio/src/cap_gphoto2.cpp: > > В функции-члене «void cv::gphoto2::DigitalCameraCapture::initContext()»: > > /dev/shm/tmp/cinelerra-goodguy-20191101/cinelerra-5.1/thirdparty/opencv/modules/videoio/src/cap_gphoto2.cpp:323:66: > > ошибка: некорректное преобразование из «void (*)(GPContext*, const char*, > > void*) {aka void (*)(_GPContext*, const char*, void*)}» в > > «GPContextErrorFunc {aka void (*)(_GPContext*, const char*, char*, void*)}» > > [-fpermissive] > > gp_context_set_error_func(context, ctxErrorFunc, (void*) this); > > ^ > > In file included from /usr/include/gphoto2/gphoto2-abilities-list.h:28:0, > > from /usr/include/gphoto2/gphoto2-library.h:28, > > from /usr/include/gphoto2/gphoto2.h:49, > > from > > /dev/shm/tmp/cinelerra-goodguy-20191101/cinelerra-5.1/thirdparty/opencv/modules/videoio/src/cap_gphoto2.cpp:32: > > /usr/include/gphoto2/gphoto2-context.h:113:6: замечание: при > > инициализации 2 -го аргумента «void gp_context_set_error_func(GPContext*, > > GPContextErrorFunc, void*)» > > void gp_context_set_error_func (GPContext *context, > > ^ > > /dev/shm/tmp/cinelerra-goodguy-20191101/cinelerra-5.1/thirdparty/opencv/modules/videoio/src/cap_gphoto2.cpp:324:68: > > ошибка: некорректное преобразование из «void (*)(GPContext*, const char*, > > void*) {aka void (*)(_GPContext*, const char*, void*)}» в > > «GPContextStatusFunc {aka void (*)(_GPContext*, const char*, char*, > > void*)}» [-fpermissive] > > gp_context_set_status_func(context, ctxStatusFunc, (void*) this); > > ^ > > In file included from /usr/include/gphoto2/gphoto2-abilities-list.h:28:0, > > from /usr/include/gphoto2/gphoto2-library.h:28, > > from /usr/include/gphoto2/gphoto2.h:49, > > from > > /dev/shm/tmp/cinelerra-goodguy-20191101/cinelerra-5.1/thirdparty/opencv/modules/videoio/src/cap_gphoto2.cpp:32: > > /usr/include/gphoto2/gphoto2-context.h:115:6: замечание: при > > инициализации 2 -го аргумента «void gp_context_set_status_func(GPContext*, > > GPContextStatusFunc, void*)» > > void gp_context_set_status_func (GPContext *context, > > ^ > > /dev/shm/tmp/cinelerra-goodguy-20191101/cinelerra-5.1/thirdparty/opencv/modules/videoio/src/cap_gphoto2.cpp:325:70: > > ошибка: некорректное преобразование из «void (*)(GPContext*, const char*, > > void*) {aka void (*)(_GPContext*, const char*, void*)}» в > > «GPContextMessageFunc {aka void (*)(_GPContext*, const char*, char*, > > void*)}» [-fpermissive] > > gp_context_set_message_func(context, ctxMessageFunc, (void*) this); > > ^ > > In file included from /usr/include/gphoto2/gphoto2-abilities-list.h:28:0, > > from /usr/include/gphoto2/gphoto2-library.h:28, > > from /usr/include/gphoto2/gphoto2.h:49, > > from > > /dev/shm/tmp/cinelerra-goodguy-20191101/cinelerra-5.1/thirdparty/opencv/modules/videoio/src/cap_gphoto2.cpp:32: > > /usr/include/gphoto2/gphoto2-context.h:121:6: замечание: при > > инициализации 2 -го аргумента «void gp_context_set_message_func(GPContext*, > > GPContextMessageFunc, void*)» > > void gp_context_set_message_func (GPContext *context, > > ^ > > /dev/shm/tmp/cinelerra-goodguy-20191101/cinelerra-5.1/thirdparty/opencv/modules/videoio/src/cap_gphoto2.cpp:339:52: > > ошибка: нет декларации «gp_camera_autodetect» в этой области видимости > > CR(gp_camera_autodetect(allDevices, context)); > > ^ > > /dev/shm/tmp/cinelerra-goodguy-20191101/cinelerra-5.1/thirdparty/opencv/modules/videoio/src/cap_gphoto2.cpp:248:27: > > замечание: in definition of macro «CR» > > if ((r_0629c47b758 = (GPHOTO2_FUN)) < GP_OK) {\ > > ^ > > make[5]: *** > > [modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_gphoto2.cpp.o] > > Ошибка 1 > > make[5]: Выход из каталога > > `/dev/shm/tmp/cinelerra-goodguy-20191101/cinelerra-5.1/thirdparty/opencv/build' > > make[4]: *** [modules/videoio/CMakeFiles/opencv_videoio.dir/all] Ошибка 2 > > make[4]: Выход из каталога > > `/dev/shm/tmp/cinelerra-goodguy-20191101/cinelerra-5.1/thirdparty/opencv/build' > > make[3]: *** [all] Ошибка 2 > > make[3]: Выход из каталога > > `/dev/shm/tmp/cinelerra-goodguy-20191101/cinelerra-5.1/thirdparty/opencv/build' > > make[2]: *** > > [/dev/shm/tmp/cinelerra-goodguy-20191101/cinelerra-5.1/thirdparty/opencv.sta] > > Ошибка 2 > > make[2]: Выход из каталога > > `/dev/shm/tmp/cinelerra-goodguy-20191101/cinelerra-5.1/plugins' > > make[1]: *** [all-recursive] Ошибка 1 > > make[1]: Выход из каталога > > `/dev/shm/tmp/cinelerra-goodguy-20191101/cinelerra-5.1' > > make: *** [all] Ошибка 2 > > > > > > I don't think gphoto2 actually needed for CinGG needs ?
