[Libav-user] Can not load ffmpeg 3.4.1 under Android because link not found

[Cooky]

Hello,

I have successfully compiled FFmpeg 3.1.11 under Linux Ubuntu and it runs fine under Android (Version >4)

This script i used:

NDK=/home/urs/Documents/android-ndk-r12b
SYSROOT=$NDK/platforms/android-14/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-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=armv7-a
PREFIX=$(pwd)/android/$CPU 
ADDI_CFLAGS="-marm -march=$CPU"
build_one


with the same script i can also compile the version 3.4.1.

The problem is, if i try to load the libs under Android with

Java.Lang.JavaSystem.LoadLibrary("avutil-55");
Java.Lang.JavaSystem.LoadLibrary("swresample-2");
Java.Lang.JavaSystem.LoadLibrary("avcodec-57");
...
avutil-55 and swresample-2 load fine, but avcodec-57 fails with the error message:

  Java.Lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol "ff_h264_mediacodec_hwaccel" referenced by "/data/app/App12.App12-1/lib/arm/libavcodec-57.so"...



What can i do? Is there some libs i have to disable in the config script?
