2019-08-05 发布 dav1d 0.4.0 dav1d 0.4.0 'Cheetah', the fast and small AV1 decoder This is the fourth major release of dav1d, the fast and small AV1 decoder, codename 'Cheetah'. It supports all the AV1 features and all bitdepths. 0.4.0 brings large improvements in speed on ARM64 (up to 25% speedup) and minor improvements on SSE and ARM. It also improves the RAM usage quite significantly, sometimes more than halving the RAM used. mingw32环境上静态编译 dav1d 0.4.0 export CC=/mingw/bin/gcc export CXX=/mingw/bin/g++ meson --prefix "/usr/local" build --buildtype release --default-library static ninja -C build ninja -C build install 如果出现一下错误 Linking target tools/dav1dplay.exe.
