【ijkplayer】引入Android项目

【ijkplayer】引入Android项目

【ijkplayer】引入Android项目(基于k0.8.8)

编译准备

git（Mac自带）、yasm（brew install yasm）、Android sdk（Android studio 默认）、ndk（r14b）、并配置环境变量

ndk 环境变量

(android-ndk-r14b)

export ANDROID_SDK=/Users/inke219223m/Library/Android/sdk/platform-toolsexport ANDROID_NDK=/Volumes/Victory/dev/android-ndk-r14bexport PATH=$PATH:$ANDROID_SDKexport PATH=$PATH:$ANDROID_NDK## mac环境需要配置下面亮项export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGSexport COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS

M1 芯片配置ndk-build

#!/bin/sh# 原来的注释掉#DIR="$(cd "$(dirname "$0")" && pwd)"#$DIR/build/ndk-build "$@"# M1 buildDIR="$(cd "$(dirname "$0")" && pwd)"arch -x86_64 /bin/bash $DIR/build/ndk-build "$@"

ijk 项目-和拉取 fmpeg 代码

# clone项目git clone 进入ijkplayer-android目录cd ijkplayer# 切换到最新代码分支git checkout -B latest k0.8.8# 会检查-ffmpeg代码 ./init-android.sh#初始化openSSL（使ijk编译后支持--list-decodersexport COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGSexport COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGSexport COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGSexport COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGSexport COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGSexport COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGSexport COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGSexport COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGSexport COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGSexport COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGSexport COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS

选择配置文件，ln -s 命令标识软连接，module.sh可以直接获取module-default.sh的配置

#If you prefer more codec/formatcd configrm module.shln -s module-default.sh module.sh#If you prefer less codec/format for smaller binary size (include hevc function)cd configrm module.shln -s module-lite-hevc.sh module.sh#If you prefer less codec/format for smaller binary size (by default)cd configrm module.shln

编译

本次编译的是 Android 项目，所以先 cd 到 android/contrib 下 执行清除命令，然后编译对于的 so 库，all 标识编译所有架构的 so，想编译 armv7a 架构则将 all 替换成 armv7a

./compile-openssl.sh clean #清除./compile-ffmpeg.sh clean #清除./compile-openssl.sh all #编译./compile-ffmpeg.sh all #编译

生成 ijkplayer 对应架构 so 文件（all 同上输入对应架构则生成对应架构动态链接库），动态链接库生成路径如下图所示（路径示例：ijkplayer-android/android/ijkplayer/ijkplayer-armv7a/src/main/libs/armeabi-v7a）

注意本步骤需要同意不受信任软件权限，​​具体参考地址​​

# 注意回到android 路径下cd ..# 执行脚步生成so 文件

到此 ijkplayer 编译完成，如果播放器之前逻辑已经写好，则直接替换项目中对应的动态链接库文件就行

使用

项目导入

首先新建一个 ijkplayerdemo 工程， 将文件夹的文件 ijkplayer/android/ijkplayer 目录下的 tool 初始化工程脚本 gradle 文件复制到刚新穿件的项目根目录，然后在根项目的 build.gradle 中加入统一版本 ext 配置，相当于一个 map，方便导入 library 统一引入配置。

ext { compileSdkVersion = 30 buildToolsVersion = "30.0.0" targetSdkVersion = 30 versionCode = 800800 versionName = "0.8.8"}

导入 ijkplayer-example

-这个项目，他本身是一个可运行的项目，并且依赖前面编译好的各个版本动态链接库 library，将其变为library 则修改该模块 build.gradle 将 apply plugin: ‘com.android.application’ 改为 apply plugin: ‘com.android.library’。

ijkplayer-example 的清单文件还设置了启动的 Activity过滤器，将其删除

各个CPU架构动态链接库 library 合并，简化项目依赖

CMakeLists.txt

处理依赖报错

ijkplayer-example依赖的包版本比较低，应该更改为我们对于版本support包，需要将ijkplayer-example的一些报错的类正确导包，和ijkplayer-java中一样，在ijkplayer-example目录下新建gradle.properties 文件并加入项目配置

POM_NAME=ijkplayer-examplePOM_ARTIFACT_ID=ijkplayer-examplePOM_PACKAGING=aar

ijkplayer-example 的 build.gardle 中productFlavors 配置删除

坑还是比较多的，不要着急，谷歌还是都能帮忙解决，注意关键字摄取，搞定完就能运行展示了，源码还需自己去理解。

将ijkplayer-example依赖到主项目工程

(dir: "libs", include: ["*.jar"]) implementation 'androidx.appcompat:appcompat:1.4.1' implementation 'com.google.android.material:material:1.6.0' implementation 'androidx.appcompat:appcompat:1.1.0' implementation 'androidx.constraintlayout:constraintlayout:2.1.4' androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0' //第三方 implementation 'tv.danmaku.ijk.media:ijkplayer-java:0.8.8' implementation 'tv.danmaku.ijk.media:ijkplayer-armv7a:0.8.8' //导入子模块 implementation project(path: ':ijkplayer-example')
