文章详细描述了如何在Android平台上为ijkplayer集成x264编码器，包括下载和编译x264源码，修改ijkplayer的ffmpeg交叉编译脚本，开启编码器配置，以及解决编译过程中遇到的问题。这使得ijkplayer能够支持视频编码功能。

ijkplayer作为一款基于ffmpeg在移动端比较流行的播放器，并没有集成编码器。如果使用ffmpeg且需要音视频编码功能的话就需要自己手动集成。
编译支持x264编码器的流程主要参考了

ijkplayer支持x264编译 - 简书
原理与ijkplayer编译支持openssl的流程类似。

1 下载x264源码

在ijkplayer源码根目录下新建init-android-x264.sh 内容如下:

IJK_x264_UPSTREAM=http://git.videolan.org/git/x264.git
IJK_x264_FORK=http://git.videolan.org/git/x264.git

IJK_x264_LOCAL_REPO=extra/x264

set -e
TOOLS=tools

echo "== pull x264 base =="
sh $TOOLS/pull-repo-base.sh $IJK_x264_UPSTREAM $IJK_x264_LOCAL_REPO

function pull_fork()
{
    echo "== pull x264 fork $1 =="
    sh $TOOLS/pull-repo-ref.sh $IJK_x264_FORK android/contrib/x264-$1 ${IJK_x264_LOCAL_REPO}
}

pull_fork "armv5"
pull_fork "armv7a"
pull_fork "arm64"
pull_fork "x86"
pull_fork "x86_64"

执行
./init-android-x264.sh
同下载ffmpeg源码一样，会在extra下生成一个x264源码文件夹，以及在android/contrib下生成5个x264各个架构的源码文件夹。

2 编译x264

增加编译脚本，在android/contrib下新建compile-x264.sh ，在android/contrib/tools 下新建do-compile-x264.sh

compile-x264.sh脚本内容如下：

UNI_BUILD_ROOT=`pwd`
FF_TARGET=$1
set -e
set +x

FF_ACT_ARCHS_32="armv5 armv7a x86"
FF_ACT_ARCHS_64="armv5 armv7a arm64 x86 x86_64"
FF_ACT_ARCHS_ALL=$FF_ACT_ARCHS_64

echo_archs() {
    echo "===================="
    echo "[*] check archs"
    echo "===================="
    echo "FF_ALL_ARCHS = $FF_ACT_ARCHS_ALL"
    echo "FF_ACT_ARCHS = $*"
    echo ""
}

echo_usage() {
    echo "Usage:"
    echo "  compile-x264.sh armv5|armv7a|arm64|x86|x86_64"
    echo "  compile-x264.sh all|all32"
    echo "  compile-x264.sh all64"
    echo "  compile-x264.sh clean"
    echo "  compile-x264.sh check"
    exit 1
}

echo_nextstep_help() {
    #----------
    echo ""
    echo "--------------------"
    echo "[*] Finished"
    echo "--------------------"
    echo "# to continue to build ffmpeg, run script below,"
    echo "sh compile-ffmpeg.sh "
    echo "# to continue to build ijkplayer, run script below,"
    echo "sh compile-ijk.sh "
}

#----------
case "$FF_TARGET" in
    "")
        echo_archs armv7a
        sh tools/do-compile-x264.sh armv7a
    ;;
    armv5|armv7a|arm64|x86|x86_64)
        echo_archs $FF_TARGET
        sh tools/do-compile-x264.sh $FF_TARGET
        echo_nextstep_help
    ;;
    all32)
        echo_archs $FF_ACT_ARCHS_32
        for ARCH in $FF_ACT_ARCHS_32
        do
            sh tools/do-compile-x264.sh $ARCH
        done
        echo_nextstep_help
    ;;
    all|all64)
        echo_archs $FF_ACT_ARCHS_64
        for ARCH in $FF_ACT_ARCHS_64
        do
            sh tools/do-compile-x264.sh $ARCH
        done
        echo_nextstep_help
    ;;
    clean)
        echo_archs FF_ACT_ARCHS_64
        for ARCH in $FF_ACT_ARCHS_ALL
        do
            if [ -d x264-$ARCH ]; then
                cd x264-$ARCH && git clean -xdf && cd -
            fi
        done
        rm -rf ./build/x264-*
    ;;
    check)
        echo_archs FF_ACT_ARCHS_ALL
    ;;
    *)
        echo_usage
        exit 1
    ;;
esac

do-compile-x264.sh脚本内容如下：

set -e

if [ -z "$ANDROID_NDK" ]; then
    echo "You must define ANDROID_NDK before starting."
    echo "They must point to your NDK directories.\n"
    exit 1
