Ubuntu 18.04 编译 ijkplayer

Ubuntu 18.04 编译 ijkplayer

1. 配置安装源
https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu
2. 配置好安装源后,安装一些组件
$ sudo apt update
$ sudo apt install vim openssh-server git curl wget tar unzip
$ sudo apt install build-essential openjdk-8-jdk yasm python
3. 下载sdk-manager
https://developer.android.com
$ wget https://dl.google.com/android/repository/sdk-tools-linux-3859397.zip
如果在Windows,可通过putty的psftp复制sdk-tools-linux-3859397.zip到linux系统
4. 解压sdk-manager
$ unzip ~/sdk-tools-linux-3859397.zip -d ~/android-sdk
5. 更新tools
$ touch ~/.android/repositories.cfg  // 可忽略
$ ./sdkmanager --update
提示许可协议,输入y回车,然后耐心等待,提示done表示完成。
6. 查看可安装列表
$ cd ~/android-sdk/tools/bin
$ ./sdkmanager --list
记住最新的sdk build tools
7. 安装sdk build-tools和ndk
$ cd ~/android-sdk/tools/bin
$ ./sdkmanager "build-tools;27.0.3"  // "ndk-bundle"
下载14版本的NDK
$ cd ~
$ wget https://dl.google.com/android/repository/android-ndk-r14b-linux-x86_64.zip
$ unzip android-ndk-r14b-linux-x86_64.zip -d ~/android-sdk
8. 删除无用的压缩包,备份android-sdk目录
$ cd ~
$ rm ~/sdk-tools-linux-3859397.zip ~/android-ndk-r14b-linux-x86_64.zip
$ tar cvzf android-sdk-ndkr14b.tar.gz android-sdk


编译ijkplayer项目
一、准备源码
https://github.com/Bilibili/ijkplayer#build-android
1. 配置环境变量
$ export ANDROID_SDK=$HOME/android-sdk
// $ export ANDROID_NDK=$ANDROID_SDK/ndk-bundle //此项目最高支持NDK14的版本,因此用下面的位置。
$ export ANDROID_NDK=$ANDROID_SDK/android-ndk-r14b
2. 下载ijkplayer源代码
$ cd ~
$ git clone https://github.com/Bilibili/ijkplayer.git ijkplayer-android
$ cd ijkplayer-android
$ git checkout -B latest k0.8.8
3. 下载相关的android ffmpeg源代码
$ ./init-android.sh
4. 备份源码
$ cd ~
$ tar cvzf ijkplayer-android.tar.gz ijkplayer-android
二、编译
1. 用bash代替dash
$ sudo dpkg-reconfigure dash
选择NO
如果新打开的shell,记得按“一1”配置ANDROID_SDK和ANDROID_NDK环境变量。
2. 选择解码包
(1)默认是较少的codec/format生成较小尺寸的包。
(2)在(1)的基础上包含hevc功能
(3)最多的codec/format
如果选择(1)请直接到下一步。否则继续操作:
$ cd ~/ijkplayer-android/config
$ rm module.sh
$ ln -s module-lite-hevc.sh module.sh  <<<< (2)
$ ln -s module-default.sh module.sh    <<<< (3)
注意,选择(2)需要为ffmpeg额外安装latm,选择(3)可能需要手动安装更多的外部库。
3. 编译ffmepg
$ cd ~/ijkplayer-android/android/contrib
$ ./compile-ffmpeg.sh clean
$ ./compile-ffmpeg.sh all
成功进行下一步。
如果报错:fatal error: linux/perf_event.h: No such file or directory
$ vim ~/ijkplayer-android/config/module.sh
在结尾加入这一行:
export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --disable-linux-perf"
保存后执行
$ ./compile-ffmpeg.sh clean
$ ./compile-ffmpeg.sh all
4. 编译ijkplayer
$ cd ~/ijkplayer-android/android
$ ./compile-ijk.sh all
5. 备份成果
$ cd ~
$ tar cvzf ijkplayer-android-build.tar.gz ijkplayer-android
三、使用
# Android Studio:
#     Open an existing Android Studio project
#     Select android/ijkplayer/ and import
#
#     define ext block in your root build.gradle
#     ext {
#       compileSdkVersion = 23       // depending on your sdk version
#       buildToolsVersion = "23.0.0" // depending on your build tools version
#
#       targetSdkVersion = 23        // depending on your sdk version
#     }
#
# If you want to enable debugging ijkplayer(native modules) on Android Studio 2.2+: (experimental)
#     sh android/patch-debugging-with-lldb.sh armv7a
#     Install Android Studio 2.2(+)
#     Preference -> Android SDK -> SDK Tools
#     Select (LLDB, NDK, Android SDK Build-tools,Cmake) and install
#     Open an existing Android Studio project
#     Select android/ijkplayer
#     Sync Project with Gradle Files
#     Run -> Edit Configurations -> Debugger -> Symbol Directories
#     Add "ijkplayer-armv7a/.externalNativeBuild/ndkBuild/release/obj/local/armeabi-v7a" to Symbol Directories
#     Run -> Debug 'ijkplayer-example'
#     if you want to reverse patches:
#     sh patch-debugging-with-lldb.sh reverse armv7a
#
# Eclipse: (obselete)
#     File -> New -> Project -> Android Project from Existing Code
#     Select android/ and import all project
#     Import appcompat-v7
#     Import preference-v7
#
# Gradle
#     cd ijkplayer
#     gradle
