I am trying to build FFmpeg because I realized that my app doesn't work for android 6.0 in x86 devices before that I have published my app with targetsdkversion 23 (It has text relocations) and now I can't publish my app using targetsdkversion 22 (This is the way that I could fix the problem). So I read a lot about this problem It seems there isn't a solution. Some people say that I can compile ffmpeg using --disable-asm flag and I can solve the problem. I want to generate a libffmeg.so for vitamio that works on x86 android 6.0.
I am using
Ubuntu 14.04 LTS
Android NDK r12b
And my example project is Vitamio-5.0.2 from Download
So I am working on this tutorial
This is my FFmpeg-Android.sh file
#!/bin/bash
export ANDROID_NDK=/home/myuser/Downloads/android-ndk-r12b
DEST=`pwd`/build/ffmpeg && rm -rf $DEST
SOURCE=`pwd`/ffmpeg
if [ -d ffmpeg ]; then
cd ffmpeg
else
git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg
cd ffmpeg
fi
git reset --hard
git clean -f -d
git checkout `cat ../ffmpeg-version`
patch -p1 <../FFmpeg-VPlayer.patch
[ $PIPESTATUS == 0 ] || exit 1
git log --pretty=format:%H -1 > ../ffmpeg-version

The other files are the same as url provides
Then the result is
I have deleted -Werror=strict-aliasing from CFLAGS and it generates the other .so files less libffmpeg.so
The error is in this code line
$CC -lm -lz -shared --sysroot=$SYSROOT -Wl,--no-undefined -Wl,-z,noexecstack $EXTRA_LDFLAGS libavutil/*.o libavutil/arm/*.o libavcodec/*.o libavcodec/arm/*.o libavformat/*.o libswresample/*.o libswscale/*.o -o $PREFIX/libffmpeg.so
I have removed ccache from export CC="ccache arm-linux-androideabi-gcc" and I have an error
I have changed --disable-asm to --enable-asm and I have compiled FFmpeg-Android.sh correctly
I copied the libffmpeg.so generated in armv6, armv7, neon and vfp files in my android studio project.
I don't know if I copied libffmpeg.so files in the correct place
armv6 -> arm64-v8a
armv7 -> armeabi-v7a
neon -> x86
And the result in Android Studio
