Looking for help to build under Windows #146

Source/filter types Face Tracker (source code)

Describe your problem I would like to do some modifications to the plug-in (source code) and then compile it. I am on Windows. I have a working development environment for obs-studio, which successfully compiles and runs obs-studio itself.

Now I am looking for a way to do the same for obs-face-tracker.

Desktop (please complete the following information):

Additional context I see the steps in the file .github/workflows/main.yml, but I don't know GitHub Workflows, and I am new to CMake as well, so I do not know, how to perform those steps on my local computer to generate a working build environment, including an .sln file for the development environment Visual Studio.

Thank you kindly in advance.

At first, you need to have directory structure like below.

And, also download model files from https://github.com/davisking/dlib-models; mmod_human_face_detector.dat.bz2 and shape_predictor_5_face_landmarks.dat.bz2. Extract them. Place mmod_human_face_detector.dat and shape_predictor_5_face_landmarks.dat under obs-face-tracker/data/dlib_cnn_model and obs-face-tracker/data/dlib_face_landmark_model, respectively.

Then, go to the directory obs-face-tracker and follow the command below. https://github.com/norihiro/obs-face-tracker/blob/573da1af2bad48b9cbd4c75a8abb45d5f6061b29/.github/workflows/main.yml#L376-L385

@CmakeArgs is a variable and you may extract the line 383 like make -S . -B build -G "Visual Studio 17 2022" -DQT_VERSION=6 -DCMAKE_SYSTEM_VERSION=10.0.18363.657 And also need to add the options starting with -DCMAKE_INSTALL_PREFIX= and -DCMAKE_PREFIX_PATH= so that make can find libobs configuration file but I don't know exactly how it should be configured.

Usually I don't use Windows. Above comment might not be insufficient.

Thank you, this just gave me the right amount of push.

I started with your cmake suggestion, and then kept adding directories for libraries cmake reported as not found, until finally this gave me no errors anymore:

cmake -S . -B build -G "Visual Studio 17 2022" -DQT_VERSION=6 -DLIBOBS_INCLUDE_DIR=$PWD/../obs-studio/libobs -DLIBOBS_LIB=$PWD/../obs-studio/libobs -Dlibobs_DIR=$PWD/../obs-studio/build_x64/libobs -Dw32-pthreads_DIR=$PWD/../obs-studio/build_x64/deps/w32-pthreads/ -Dobs-frontend-api_DIR=$PWD/../obs-studio/build_x64/UI/obs-frontend-api/ -DQt6_DIR=$PWD/../obs-studio/.deps/obs-deps-qt6-2023-11-03-x64/lib/cmake/Qt6/ -DQt6CoreTools_DIR=$PWD/../obs-studio/.deps/obs-deps-qt6-2023-11-03-x64/lib/cmake/Qt6CoreTools/ -DQt6GuiTools_DIR=$PWD/../obs-studio/.deps/obs-deps-qt6-2023-11-03-x64/lib/cmake/Qt6GuiTools/

I assume there is a better way, but I put it here for future reference for others who are similarly clueless about cmake as I am but might want to work on this.

and I needed do update libvisca after this to be able to do a Debug build:

cd libvisca
git pull origin HEAD
