1、 This article belongs to the novice to , Mainly about the compilation process ;

2、 The article is too long , Lots of pictures , And the compilation process is very time-consuming ;

3、 Please do it in order , Free play is easy to go wrong , Don't ask me how I know ......

Two 、 Environmental Science

1、 Hardware preparation

（1） What I have in my hand is CM4 belt emmc Version of （lite Direct brush of SD Just put it on the card ）

（2） Taobao bought IO plate

This is the link

2、 Brush system

（1） Insert these two jumper caps before brushing the system
（2）win10 Install this driver on

Download address

（3） The installation directory opens this rpiboot.exe

The status after opening is as follows ：

（4） And then use type-c Wire will be connected IO On the board type-c Mouth and win10 Of usb Mouth connection

（5） The successful connection shows the following （ The window will close automatically ）

（6） And then you can win10 It is recognized as u Dish up

（7） Download address of official burning tool Select this operating system after installation

Tips ：emmc Burning the system is slow , Please be patient

This tool also has a new function , It is to write the settings automatically when burning the system , Save a lot of trouble , Strongly recommend ！

3、 Ready to power on

After burning the system , power failure , Pull off both jumper caps , Power on again

Domestic links

2、 install ：

tar xvf x264-master.tar.bz2

cd x264-master

./configure --host=arm-linux --cross-prefix=/usr/bin/aarch64-linux-gnu- --disable-asm --enable-shared

make

sudo make install

sudo cp _install/include /usr/ -rf

sudo cp _install/lib /usr/ -rf

5、 ... and 、 The installation integrates metaRTC Of ffmpeg

explain ： This one contains ffmpeg and metaRTC

1、 download ：

Original link
Domestic links

2、 Compile third-party packages

unzip ffmpeg-metartc-main.zip

cd ffmpeg-metartc-main/FFmpeg-n4.3.3/metartc3

The folder contains this 3 A package , All need to be compiled

Links to articles

(1) srtp2

tar xvf libsrtp-2-fit.tar.gz

cd libsrtp-2-fit

./configure

Find this file

In the 82 Row insertion static

After modifying the effect

Links to articles

After modifying the above file, compile （ Otherwise, the report will be wrong , Try it ）

make

make The success is as follows

sudo make install

(2) openssl-1.1-fit

tar xvf openssl-1.1-fit.tar.gz

cd openssl-1.1-fit/

export CC=/usr/bin/aarch64-linux-gnu-gcc

./Configure linux-aarch64

make

sudo make install

(3) SpeexDSP

sudo apt-get install -y autoconf automake libtool

You read that right , You really need to install this first ......

tar xvf speexdsp-SpeexDSP-1.2.0.tar.gz

cd speexdsp-SpeexDSP-1.2.0/

sh autogen.sh

./configure

make

sudo make install

Can't bear to see this ？？？

It's not over yet , Let's move on ！！！

(4) metaRTC-3.0release

1) download ：

Original link
Domestic links

2) compile ：

sudo apt-get install cmake

You read that right , You really need to install this first ......

unzip metaRTC-3.0release.zip

cd metaRTC-3.0release/libmetartccore3

sh cmake_arm.sh

cd build

ls

Confirm whether there is this file

sudo cp libmetartccore3.a /usr/local/lib 

3、 Everything is available. , Protagonist on stage ：

(1） Go back to the home directory

cd ~/mateRTC3/ffmpeg-metartc-main/FFmpeg-n4.3.3/

Let's take a photo first

(2） The east wind rises and the clouds fly ！

This is why I have been tossing about for a long time ......

./configure --enable-shared --enable-libx264 --enable-gpl --extra-libs='-L/path/metartc3 -lmetartccore3 -lspeexdsp -lpthread -lsrtp2 -lssl -lcrypto -ldl'

When you see this picture, it means success

Then there is a long make, Probably 30 Minutes! …Orz

make

sudo make install
