add H266/VVC support

[Ciancy28]

ffmpeg 7.1 introduced h266 support
support for --enable-libvvdec and --enable-libvvenc should be added to the build parameters i think?

[rdp]

PR welcome though I might get to it some year...

I spent some time trying to add a build_libvvenc() to the script. Their CMake config seems to ignore CMAKE_FIND_ROOT_PATH and CMAKE_FILE_ROOT_PATH_MODE_LIBRARY, which I think is needed to find the include that is added. (compilation complains about mutex not being part of std::)
Not sure if there is an alternative workflow already in the script to account for this

You could check https://github.com/m-ab-s/media-autobuild_suite and see if there's any magic sauce :)

build_libvvenc() {
  do_git_checkout https://github.com/fraunhoferhhi/vvenc.git libvvenc_git 
  cd libvvenc_git 
    do_cmake "-S . -B build/release-static -DCMAKE_INSTALL_PREFIX=$mingw_w64_x86_64_prefix -DCMAKE_BUILD_TYPE=Release -DVVENC_ENABLE_LINK_TIME_OPT=OFF -DVVENC_INSTALL_FULLFEATURE_APP=ON -GNinja" && cd build/release-static && ninja -j 16 && ninja install
  cd ../../..
}

build_libvvdec() {
  do_git_checkout https://github.com/fraunhoferhhi/vvdec.git libvvdec_git 
  cd libvvdec_git  
    do_cmake "-S . -B build/release-static -DCMAKE_INSTALL_PREFIX=$mingw_w64_x86_64_prefix -DCMAKE_BUILD_TYPE=Release -DVVDEC_ENABLE_LINK_TIME_OPT=OFF -DVVDEC_INSTALL_VVDECAPP=ON -GNinja" && cd build/release-static && ninja -j 16 && ninja install 
  cd ../../..
}

.pc files something like this, no sed required if using mingw v12

Libs: -L${libdir} -lvvdec
Libs.private: -lstdc++ -lmingw32 -lgcc -lmingwex -lkernel32 -lpthread -ladvapi32 -lshell32 -luser32 -lkernel32 -lmingw32 -lgcc -lmingwex -lkernel32
Cflags: -I${includedir}

vvdec needs that and patch will fail on many versions, try release/7.1 for success for vvenc as well

config_options+=" --enable-libvvdec" && apply_patch "https://github.com/raw/wiki/fraunhoferhhi/vvdec/data/patch/v6-0001-avcodec-add-external-dec-libvvdec-for-H266-VVC.patch" -p1

Might require v10+ of mingw, I used v12
