The other thing is, I found libxcam (https://github.com/intel/libxcam)
depend on a lot of 3rd libs
"
If --enable-gst, need install libgstreamer1.0-dev,
libgstreamer-plugins-base1.0-dev
If --enable-aiq, need get ia_imaging lib which we don't support
If --enable-libcl, need compile or install OpenCL driver
If --enable-opencv, suggest OpenCV versions [3.0.0 - 4.0.0) (or: OpenCV Wiki)
If --enable-render, need compile OpenSceneGraph library with configure
option "-DOSG_WINDOWING_SYSTEM=X11"
If --enable-gles, need to install Mesa3D library
If --enable-vulkan, need to install Mesa3D library
If --enable-avx512, need to install GCC version > 4.9 ( CPUs With
AVX-512 required)
If --enable-dnn, need to compile OpenVino inference-engine
If --enable-json, need to install json.hpp
"
Is it a good idea to wrap a lib like this in AVFilter?
