• 修改ffmpeg-android-maker/scripts/ffmpeg/build.sh 中 configure部分内容，这里添加了disable-doc，否则会报cc1错误

  ./configure \
    --prefix=${BUILD_DIR_FFMPEG}/${ANDROID_ABI} \
    --enable-cross-compile \
    --target-os=android \
    --arch=${TARGET_TRIPLE_MACHINE_ARCH} \
    --sysroot=${SYSROOT_PATH} \
    --cc=${FAM_CC} \
    --cxx=${FAM_CXX} \
    --ld=${FAM_LD} \
    --ar=${FAM_AR} \
    --as=${FAM_CC} \
    --nm=${FAM_NM} \
    --ranlib=${FAM_RANLIB} \
    --strip=${FAM_STRIP} \
    --extra-cflags="-O3 -fPIC $DEP_CFLAGS" \
    --extra-ldflags="$DEP_LD_FLAGS" \
    --enable-shared \
    --disable-static \
    --disable-vulkan \
    --enable-nonfree \
    --enable-libfdk-aac \
    --disable-doc \
    --pkg-config=${PKG_CONFIG_EXECUTABLE} \
    ${EXTRA_BUILD_CONFIGURATION_FLAGS} \
    $ADDITIONAL_COMPONENTS || exit 1
  

  • export PKG_CONFIG_PATH=${FDK_PKG_CONFIG_PATH}:${PKG_CONFIG_PATH}，即fdk-aac生成的pkgconfig路径

  • ./ffmpeg-android-maker.sh -abis=arm64 -android=34
