ijkplayer 编译
编译可以参考官方说明
简要步骤�说明：
- 将代码下载到本地
git clone https://github.com/Bilibili/ijkplayer
-
设定ndk环境
- 下载对应平台的ndk工具包，官网地址
- 设置ndk的编译环境，因为我使用的是mac，就直接
export ANDROID_NDK=/ndk-path
-
初始化ijkplayer为android编译环境
./init-android.sh -
编译ffmpeg之前准备
因为ijkplayer还是�依赖于ffmpeg的一些功能，所以在�进行ijkplayer的编译之前，首先需要满足ffmpeg的编译条件。最主要的就是yasm的安装，以mac为例，安装yasmbrew install yasm -
开始编译ffmpeg
cd android/contrib ./compile-ffmpeg.sh clean ./compile-ffmpeg.sh all -
编译ijkplayer
./compile-ijk.sh all
ijkplayer 的使用
使用前的说明
在完成上面的编译过程之后，可以在ijkplayer中发现一个android工程，简要的目录如下：
+---/path-to-ijkplayer/android/ijkplayer
|
+---ijkplayer-arm64
|
+---ijkplayer-armv5
|
+---ijkplayer-armv7a
|
+---ijkplayer-x86
|
+---ijkplayer-x86-64
|
+---ijkplayer-java
|
+---ijkplayer-exo
|
+---tools
如上目录为ijkplayer在android平台上需要用到的库，从命名上可以看出，以上modules中包含了这几类：
-
ijkplayer-arm*和ijkplayer-x86*，实现了不同平台下的so库。 -
ijkplayer-java和ijkplayer-exo, 为封装好的ijkplayer的java层api。 -
tools，编译需要用到的脚本程序
如何使用
�新建android工程，命名为：
ijkplayer-demo。讲上文中�表示出来的文件夹全部拷贝到新建的android工程目录下。
-
修改�新建工程中的
settings.gradle:include ':ijkplayer-armv5', ':ijkplayer-x86_64' include ':ijkplayer-armv7a' include ':ijkplayer-arm64' include ':ijkplayer-x86' include ':ijkplayer-java' include ':ijkplayer-exo' include ':app' -
修改
/path-to-ijkplayer-demp/build.gradle// Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:2.3.3' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } allprojects { repositories { jcenter() } } ext { compileSdkVersion = 23 buildToolsVersion = "23.0.3" targetSdkVersion = 23 versionCode = 800000 versionName = "0.8.0" } task clean(type: Delete) { delete rootProject.buildDir } -
修改
/path-to-ijkplayer-demp/app/build.gradleapply plugin: 'com.android.application' android { compileSdkVersion 25 buildToolsVersion "25.0.1" defaultConfig { applicationId "com.test.ijkplayer.hankun.ijkplayer_test" minSdkVersion 21 targetSdkVersion 25 versionCode 1 versionName "1.0" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { exclude group: 'com.android.support', module: 'support-annotations' }) compile 'com.android.support:appcompat-v7:25.1.1' compile 'com.android.support.constraint:constraint-layout:1.0.2' testCompile 'junit:junit:4.12' compile project(':ijkplayer-java') compile project(':ijkplayer-arm64') compile project(':ijkplayer-armv5') compile project(':ijkplayer-armv7a') compile project(':ijkplayer-x86') compile project(':ijkplayer-x86_64') } -
给app添加权限
AndroidManifest.xml <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> -
��app的布局文件
<?xml version="1.0" encoding="utf-8"?> <android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.test.ijkplayer.hankun.ijkplayer_test.MainActivity"> <RelativeLayout android:layout_width="368dp" android:layout_height="495dp" tools:layout_editor_absoluteY="8dp" tools:layout_editor_absoluteX="8dp"> <Button android:id="@+id/button_prepare" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="start" android:layout_alignParentTop="true" android:layout_alignParentStart="true" /> <TextureView android:id="@+id/show_screen" android:layout_width="400dp" android:layout_height="200dp" android:layout_below="@+id/button_prepare" /> </RelativeLayout> </android.support.constraint.ConstraintLayout> -
��MainActivity代码
package com.test.ijkplayer.hankun.ijkplayer_test; import android.content.Context; import android.graphics.SurfaceTexture; import android.net.Uri; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.Surface; import android.view.TextureView; import android.view.View; import android.widget.Button; import tv.danmaku.ijk.media.player.IMediaPlayer; import tv.danmaku.ijk.media.player.IjkMediaPlayer; public class MainActivity extends AppCompatActivity { private String source_url = "rtsp://192.168.1.106:8554/test.mkv"; private Context _ctx = this; public IjkMediaPlayer player = null; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); player = new IjkMediaPlayer(); TextureView tv = (TextureView)findViewById(R.id.show_screen); tv.setSurfaceTextureListener(new TextureView.SurfaceTextureListener() { @Override public void onSurfaceTextureAvailable(SurfaceTexture surface, int width, int height) { try { player.setSurface(new Surface(surface)); } catch (Exception e) { e.printStackTrace(); } } @Override public void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height) { } @Override public boolean onSurfaceTextureDestroyed(SurfaceTexture surface) { return false; } @Override public void onSurfaceTextureUpdated(SurfaceTexture surface) { } }); Button btn_prepare = (Button) findViewById(R.id.button_prepare); btn_prepare.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // init player IjkMediaPlayer.loadLibrariesOnce(null); IjkMediaPlayer.native_profileBegin("libijkplayer.so"); player.setOnPreparedListener(mPreparedListener); try { player.setDataSource(_ctx, Uri.parse(source_url)); player.prepareAsync(); } catch (Exception e) { e.printStackTrace(); } } }); } IMediaPlayer.OnPreparedListener mPreparedListener = new IMediaPlayer.OnPreparedListener() { @Override public void onPrepared(IMediaPlayer mp) { player.start(); } }; }
到这里，就完成了一个最简单的ijkplayer的demo。剩下的就是认真看ijkplayer的实现了。
