Hi all! :D I'm here for asking about a strange issues. In my application I receive a lot of images via Web. For storing this images I use the VideoWriter class to create a video. Everything work fine if I set the FPS above 20. In other case I can't create the file. This is a structural choices or some sort of a bug? This is not for me a big issues, I would only prefer to see the video more slowly

Nice :D What I don't want to do is what I should do :) I don't want to use old cv too. Now, I will try to rebuild it all

But if we use ocv230, we have to use VS2010? Or use V100 toolset on VS2012?

I have the same problem. I comment this post to give visibility to it. Maybe someone have the solution

Thanks, but the problem isn't in Ninja installation. I found a solution in this topic:

http://answers.opencv.org/question/19350/building-opencv4android-cmake_cxx_compiler_env_var/

The script have to be run in <opencv_source_dir>/platforms and not in <opencv_source_dir>/platforms/winrt/

There is an error on the page http://code.opencv.org/projects/opencv/wiki/WindowsRT How could I notify this to the author to fix the istruction?

Hi! Sorry for the trivial question but I'm having real problem with the build. Where should I run the scripts (scripts/cmake_winrt.cmd)? From <opencv_source_dir>/platforms/winrt/ (so >..\scripts/cmake_winrt.cmd) or in a new console?

In the first case I have to edit cmake_winrt.cmd changing the last line from cmake.exe ... -DCMAKE_TOOLCHAIN_FILE=..\winrt\arm.winrt.toolchain.cmake ..\ ..

to

cmake.exe ... -DCMAKE_TOOLCHAIN_FILE=..\winrt\arm.winrt.toolchain.cmake ..\ ..\ ..

otherway it can't find CMakeLists.txt But after I have maked this I got a lot of "Missing variable" from CMake

I find this page opencv/wiki/WindowsRT but I can't build anything. The path to VS 11 is wrong and when I have correct that and other little errors I got this:

C:\opcv\opencv\platforms\winrt\build_winrt_arm>cmake.exe -GNinja -DCMAKE_BUILD_TYPE=Release -DENABLE_WINRT_MODE=ON -DWITH_FFMPEG=OFF -DWITH_MSMF=OFF -DWITH_DSHOW=OFF -DWITH_VFW=OFF -DWITH_OPENEXR=OFF -DWITH_CUDA=OFF -DBUILD_opencv_gpu=OFF -DBUILD_opencv_python=OFF -DBUILD_opencv_java=OFF -DCMAKE_TOOLCHAIN_FILE=..\winrt\arm.winrt.toolchain.cmake   ..\..\..

I don't know enought how to use CMake so I'm be halted by this. So I can't tell you how well this thing go.
