Ijkplayer compilation process record

Environmental Science : ubuntu 20 - x64
Source code : ijkPlayer and ffmpeg Source code from github Transferred to the gitee On .

First step Install and develop common tools and libraries

 Tools 
install git, make, yasm, curl, wget
 Library content .
apt-get install libncurses5 libncurses5-dev openssl 
android development environment 
gradle、 java-11、android_sdk、android_ndk

The second step from gitee.com Cloned ijkPlayer Source code , modify init-android.sh Medium github.com Download address . as follows ：

IJK_FFMPEG_UPSTREAM=https://gitee.com/ljblqtechcom/FFmpeg.git
IJK_FFMPEG_FORK=https://gitee.com/ljblqtechcom/FFmpeg.git
IJK_FFMPEG_COMMIT=ff3.4--ijk0.8.7--20180103--001
IJK_FFMPEG_LOCAL_REPO=extra/ffmpeg

And then execute ./init-android.sh It is normal to pull the source code , Otherwise, the general report Gnutls Error of , I tried to recompile git-2.7 Source code , It's not solved .
Use this method to pull the source code okay.

The third step compile 、 and ndk Version selection
I'm using android-ndk-r14b-linux-x86_64.zip edition , I have used several versions and failed to compile .

3.1 Export environment variables

export ANDROID_SDK=~/Android/Sdk
export ANDROID_NDK=~/Android/Sdk/ndk/android-ndk-r14b
export PATH=$PATH:$ANDROID_NDK:$ANDROID_SDK:$ANDROID_SDK/platform-tools

3.2 modify compile_ffmpeg.sh and compile_ijk.sh Adaptation platform .

Put these two scripts in the adaptation platform armv5 Removed , as follows :

#ACT_ABI_64="armv5 armv7a arm64 x86 x86_64"
ACT_ABI_64="armv7a arm64 x86 x86_64"

The two files are modified in the same way .

3.3 compile ffmpeg Dependency library and ijkplayer library

Compiling ijkplayer The whole process , Special attention should be paid to ndk edition , I use ndk14 edition . There are many pits in the higher version .
Next we will use ijkPlayer Write a support H264 Raw stream playback Demo.
