I am trying to convert the data from an industry camera to a cv::Mat. This is the error I get when backtracing the segmentation fault in gdb.
#0 __memcpy_sse2_unaligned () at ../sysdeps/x86_64/multiarch/memcpy-sse2-unaligned.S:35

So I can clearly say that there is any problem with the command to memcpy:
std::memcpy(mat.ptr(),static_cast<char*>(mRequest->imageData.read()), mRequest->imageSize.read());
Now I don't really understand why the error is occuring. In another version of the program I am using it is working, but the images look very bad.
Maybe one of you has an idea what a possible error source could be.
