‘AVFilter’ has no member named ‘init_dict’

[dprh]

Hi,
I'm trying to build on Windows using WSL2 and have compilation issue on step 10.

libavfilter/vf_transform360.c: At top level:
libavfilter/vf_transform360.c:479:6: error: ‘AVFilter’ has no member named ‘init_dict’
  479 |     .init_dict   = init_dict,

And some warnings.

At previous step also had ERROR: opencv not found using pkg-config which looks to be solved by adding
export PKG_CONFIG_PATH=/usr/lib/x86_64-linux-gnu/pkgconfig/ before calling configure.

I did something wrong or ffmpeg sources became incompatible ?

I replaced init_dict by preinit as found there: https://patchwork.ffmpeg.org/project/ffmpeg/patch/AM7PR03MB66608B0D16FCD0B039E0F1128FD99@AM7PR03MB6660.eurprd03.prod.outlook.com/
It compiled but getting many link errors around Mat constructors and destructors. Starting by:
/usr/bin/ld: /usr/local/lib/libTransform360.a(VideoFrameTransformHandler.cpp.o): in function void std::_Destroycv::Mat(cv::Mat*)':
VideoFrameTransformHandler.cpp:(.text.ZSt8_DestroyIN2cv3MatEEvPT[ZSt8_DestroyIN2cv3MatEEvPT]+0x18): undefined reference to cv::Mat::~Mat()' /usr/bin/ld: /usr/local/lib/libTransform360.a(VideoFrameTransformHandler.cpp.o): in function std::pair<int const, cv::Mat>::~pair()':

fixed by adding manually pkg-config --cflags --libs opencv4 in Makefile when processing OBJ files.
Now get an error when I run the command ./ffmpeg -i /mnt/d/drift_estimation.mp4 -vf transform360="input_stereo_format=MONO :cube_edge_length=512 :interpolation_alg=cubic :enable_low_pass_filter=1 :enable_multi_threading=1 :num_horizontal_segments=32 :num_vertical_segments=15 :adjust_kernel=1" /mnt/d/output.mp4
