libavif has basic code coverage report support via clang (LLVM) and aviftest. Here's a basic example:

# Ensure you're using clang (skip this if it is the default on your system)
export CC=clang
export CXX=clang++

# build AOM locally (or any other codecs, optional)
cd ext
$SHELL aom.cmd
cd ..

# build libavif with local codecs and coverage enabled. Tweak the cmake commandline as appropriate.
mkdir build
cd build
cmake -G Ninja -DBUILD_SHARED_LIBS=0 -DAVIF_CODEC_AOM=1 -DAVIF_LOCAL_AOM=1 -DAVIF_ENABLE_COVERAGE=1 -DAVIF_BUILD_TESTS=1 ..

# Generate a coverage report via aviftest
ninja avif_coverage
