我已经关注了很多关于 buildinf ffmpeg.so 文件的教程,比如
http://enoent.fr/blog/2014/06/20/compile-ffmpeg-for-android/
http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/
还有更多教程,但最后我每次不知道如何解决它时都坚持这个错误请任何人知道如何解决它然后帮助我
我的 build.sh 文件看起来像这样
NDK=C:/Users/Benzatine/Downloads/android-ndk-r10e
SYSROOT=$NDK/platforms/android-19/arch-arm/
TOOLCHAIN=$NDK/toolchains//arm-linux-androideabi-4.8/prebuilt/windows-x86_64
function build_one
{
./configure \
--prefix=$PREFIX \
--enable-shared \
--disable-static \
--disable-doc \
--disable-ffmpeg \
--disable-ffplay \
--disable-ffprobe \
--disable-ffserver \
--disable-avdevice \
--disable-doc \
--disable-symver \
--cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
--target-os=linux \
--arch=arm \
--enable-cross-compile \
--sysroot=$SYSROOT \
--extra-cflags="-Os -fpic $ADDI_CFLAGS" \
--extra-ldflags="$ADDI_LDFLAGS" \
$ADDITIONAL_CONFIGURE_FLAG
make clean
make
make install
}
CPU=arm
PREFIX=$(pwd)/android/$CPU
ADDI_CFLAGS="-marm"
build_one
但是当它执行 make 命令时,它会给出以下错误
LD libswscale/libswscale-3.so
