    编译vlc源

    官方文档:https://wiki.videolan.org/AndroidCompile/

    我们按照官方文档首先需要下载相应的软件:

    sudo apt-get install automake ant autopoint cmake build-essential libtool-bin  patch pkg-config protobuf-compiler ragel subversion unzip git openjdk-8-jre openjdk-8-jdk flex python wget

    请不要直接复制官网的软件下载,会出现无法下载的问题,因为\和空格无法删除

    然后我们需要jdk1.8,首先我们可以先看下Java的版本:java -version

    openjdk version "11.0.6" 2020-01-14

    OpenJDK Runtime Environment (build 11.0.6+10-post-Ubuntu-1ubuntu118.04.1)

    OpenJDK 64-Bit Server VM (build 11.0.6+10-post-Ubuntu-1ubuntu118.04.1, mixed mode)

    有一些有自带的jdk,如上,这时候就需要重新下载1.8,为什么?

    如果不下载1.8并且配置的话会报下面的这个错误

    compile:

        [javac] /root/myworkdir/vlc-android/vlc/contrib/contrib-android-aarch64-linux-android/bluray/src/libbluray/bdj/build.xml:26: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds

        [javac] Compiling 33 source files to /root/myworkdir/vlc-android/vlc/contrib/contrib-android-aarch64-linux-android/bluray/src/libbluray/bdj/build

        [javac] warning: [options] bootstrap class path not set in conjunction with -source 5

        [javac] error: Source option 5 is no longer supported. Use 6 or later.

        [javac] error: Target option 1.5 is no longer supported. Use 1.6 or later.

    BUILD FAILED

    /root/myworkdir/vlc-android/vlc/contrib/contrib-android-aarch64-linux-android/bluray/src/libbluray/bdj/build.xml:26: Compile failed; see the compiler error output for details.

    Total time: 1 second

    Makefile:2618: recipe for target 'all-local' failed

    make[1]: *** [all-local] Error 1

    make[1]: Leaving directory '/root/myworkdir/vlc-android/vlc/contrib/contrib-android-aarch64-linux-android/bluray'

    ../../contrib/src/bluray/rules.mak:56: recipe for target '.bluray' failed

    make: *** [.bluray] Error 2

    这个错误就是需要一个1.8的jdk,这时候我们把Linux版本的jdk1.8下载好之后(这里不贴链接),需要配置Java环境

    sudo vim /etc/profile

    在最后一行加上

    export JAVA_HOME=/root/myworkdir/jdk1.8.0_11//这里写上自己的jdk路径

    export JAVA_BIN=$JAVA_HOME/bin

    export JAVA_LIB=$JAVA_HOME/lib

    export CLASSPATH=.:$JAVA_LIB/tools.jar:$JAVA_LIB/dt.jar

    export PATH=$JAVA_BIN:$PATH

    开始编译

    ./buildsystem/compile.sh -a arm64-v8(这个地方填写的是cpu版本)

    如果你不知道cpu版本怎么写,可以

    ./buildsystem/compile.sh --help

    进行查看

    Use -a to set the ARCH:

      ARM:    (armeabi-v7a|arm)

      ARM64:  (arm64-v8a|arm64)

      X86:    x86, x86_64

    Use --release to build in release mode

    Use --signrelease to build in release mode and sign apk, see vlc-android/build.gradle

    Use -s to set your keystore file and -p for the password

    Use -c to get a ChromeOS build

    Use -l to build only LibVLC

    Use -b to bypass libvlc source checks (vlc custom sources)

    现在就正式开始编译
