Hi,
I am amazed that nobody came to that earlier, but if
opencv-3.1.0 is installed as per the book instructions,
gst-plugins-bad does not build. The error is:
------------------------
make[3]: Entering directory
'/sources/gst10-plugins-bad/gst-plugins-bad-1.10.2/ext/opencv'
CXX libgstopencv_la-gstopencv.lo
In file included from gstopencv.cpp:41:0:
gstsegmentation.h:53:32: fatal error: opencv2/bgsegm.hpp: No such file or
directory
#include <opencv2/bgsegm.hpp>
^
compilation terminated.
make[3]: *** [Makefile:1016: libgstopencv_la-gstopencv.lo] Error 1
-----------------------
After much research (I'm really not good at finding
things on internet, thanks Arch linux), I found that
the bgsegm module is from the opencv_contrib
package, and not included in the main opencv
package (there is a cudabgsegm module in the
main pacakge, but not available if not using cuda,
that is, nvidia proprietary graphics driver). I have
not yet tried to build the opencv_contrib package,
nor to build gst-plugins-bad with that package
installed. But I wanted to report to see whether
anybody could confirm. I'd say that if confirmed,
we should add the opencv_contrib package as
optional (or disable gstopencv in gst-plugins-bad).
Regards,
Pierre
