FFMPEG avcodec_parameters_copy Android 上崩溃

问：

我是新手，我正在尝试用 Android ffmpeg 创建一个多路复用器应用程序，所以我通过 Ubuntu 编译 .so lib：

API=21
CPU=armv8-a
ARCH=arm64
PREFIX=$(pwd)/android/$CPU/$ARCH
TOOLCHAIN=/root/android-ndk-r21e/toolchains/llvm/prebuilt/linux-x86_64
CROSS_PREFIX=$TOOLCHAIN/bin/aarch64-linux-android-
CC=$TOOLCHAIN/bin/aarch64-linux-android$API-clang
CXX=$TOOLCHAIN/bin/aarch64-linux-android$API-clang++
SYSROOT=$TOOLCHAIN/sysroot
OPTIMIZE_CFLAGS="-march=$CPU"

./configure \
        --prefix=$PREFIX \
        --arch=$ARCH \
        --cpu=$CPU \
        --cross-prefix=$CROSS_PREFIX \
        --cc=$CC \
        --cxx=$CXX \
        --sysroot=$SYSROOT \
        --extra-cflags="-Os -fPIC $OPTIMIZE_CFLAGS" \
        --target-os=android \
        --enable-cross-compile \
        --disable-gpl \
        --enable-shared \
        --disable-static \
        --disable-programs \
        --disable-ffmpeg \
        --disable-ffplay \
        --disable-ffprobe \
        --disable-doc \
        --disable-htmlpages \
        --disable-manpages \
        --disable-txtpages

我还得到了一些 MUXER 的 C++ 代码片段：

// blah...blah...

我已经重建了两次.so lib，它不起作用。 谁能告诉我为什么代码在Linux（pc）上运行良好，但在Android上却崩溃了？ 而且我真的不确定如何在 Android 中调试 C++ 代码......任何帮助将不胜感激，提前TKS!!
