RV1126平台搭建推流开发环境

我的交叉编译器的地址：

/home/liefyuan/rv1126/RV1126_RV1109_LINUX_SDK_V2.1.0_20210512/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-

一、libx264交叉编译

进入libx264-git目录开始交叉编译，这里要注意–cross-prefix交叉工具链地址，也就是放在sdk里面的位置，这里我位置仅供参考(后面的交叉工具链地址都是这个)：

开始交叉编译配置：

./configure --prefix=/home/liefyuan/rv1126/RV1126_RV1109_LINUX_SDK_V2.1.0_20210512/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf- --enable-shared




./configure --prefix=/opt/arm_libx264 --host=arm-linux --cross-prefix=/home/liefyuan/rv1126/RV1126_RV1109_LINUX_SDK_V2.1.0_20210512/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf- --enable-shared --disable-static

liefyuan@ubuntu:~/rv1126/3th_lib/ffmpeg_lib/libx264-git$ ./configure --prefix=/opt/arm_libx264 --host=arm-linux --cross-prefix=/home/liefyuan/rv1126/RV1126_RV1109_LINUX_SDK_V2.1.0_20210512/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf- --enable-shared --disable-static
Unknown option --disable-static, ignored

libx264:       internal

chroma format: all

You can run 'make' or 'make fprofiled' now.

然后进行交叉编译：

make -j16
sudo make install

二、libx265交叉编译

步骤一：
解压libx265.tar.gz压缩包

步骤二：
修改CMakeList.txt文件

路径在：vim currrnt_dir/libx265-git/source/CMakeLists.txt

在文件头部添加以下信息：

SET(CMAKE_SYSTEM_NAME Linux)
SET(CMAKE_SYSTEM_PROCESSOR arm)
SET(CMAKE_C_COMPILER "/home/hao/shared/rv1126_rv1109_linux_sdk_v1.8.0_20210224/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc")
SET(CMAKE_CXX_COMPILER "/home/hao/shared/rv1126_rv1109_linux_sdk_v1.8.0_20210224/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++")
set(CMAKE_EXE_LINKER_FLAGS "-ldl")
#set(CMAKE_CXX_FLAGS -ldl)
add_compile_options(-fPIC)

步骤三：

mkdir currrnt_dir/libx265-git/source/build

进入：cd currrnt_dir/libx265-git/source/build

cmake -DCMAKE_INSTALL_PREFIX=/opt/arm_libx265_install ..

make -j32

sudo make install

修改cmake文件：/libx265-git/source/CMakeLists.txt
在文件头部添加如下信息：

SET(CMAKE_SYSTEM_NAME Linux)
SET(CMAKE_SYSTEM_PROCESSOR arm)
SET(CMAKE_C_COMPILER "/home/liefyuan/rv1126/RV1126_RV1109_LINUX_SDK_V2.1.0_20210512/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc")
SET(CMAKE_CXX_COMPILER "/home/liefyuan/rv1126/RV1126_RV1109_LINUX_SDK_V2.1.0_20210512/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++")
set(CMAKE_EXE_LINKER_FLAGS "-ldl")
#set(CMAKE_CXX_FLAGS -ldl)
add_compile_options(-fPIC)

建立build文件夹，并进入该文件夹下，同时进行编译
运行命令：

cmake -DCMAKE_INSTALL_PREFIX=/opt/arm_libx265_install ..

然后进行编译安装

make -j16
make install

编译报错
1、报错一：

...

编辑文件：

vim /home/liefyuan/rv1126/3th_lib/ffmpeg_lib/libx265-git/source/common/param.cpp 

1418gg

由下面

#define BOOL(param, cliopt) \
    s += sprintf(s, " %s", (param) ? cliopt : "no-"cliopt);

改成这样

#define BOOL(param, cliopt) \
    s += sprintf(s, " %s", (param) ? cliopt : " no- " cliopt);

2、报错二：

和上面的错误一样，改那个文件的那个地方，加三个空格，"no-"改为" no- "

然后就编译成功了！

    _M_realloc_insert(end(), std::forward<_Args>(__args)...);
    ^~~~~~~~~~~~~~~~~
[100%] Linking CXX executable x265

编译成功后记得安装make install。

三、openssl交叉编译

下载openssl源码：

wget https://www.openssl.org/source/old/1.1.1/openssl-1.1.1f.tar.gz

解压：

tar -zxvf openssl-1.1.1f.tar.gz

进入目录

cd openssl-1.1.1f/

配置

./config no-asm shared no-async --prefix=/opt/arm_openssl --cross-compile-prefix=/home/liefyuan/rv1126/RV1126_RV1109_LINUX_SDK_V2.1.0_20210512/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-

编译

make

安装

sudo make install

报错：arm-linux-gnueabihf-gcc: error: unrecognized command line option ‘-m64’
解决方法：在顶层的Makefile中，找到有 ‘-m64’的地方（两处），将其删除。

四、libsrt交叉编译

把openssl的交叉编译库拷贝到

打开openssl的lib目录：

root@ubuntu:/opt/arm_openssl/lib# ls
engines  engines-1.1  libcrypto.a  libcrypto.so  libcrypto.so.1.0.0  libssl.a  libssl.so  libssl.so.1.0.0  pkgconfig

打开Openssl的include目录
把openssl目录拷贝到srt/haicrypt目录下

cp -r openssl/ /home/liefyuan/rv1126/3th_lib/ffmpeg_lib/srt/haicrypt

进入srt目录下进行配置
先删除CMakeCache.txt文件，再配置

./configure --prefix=/opt/arm_libsrt --openssl-include-dir=/opt/arm_openssl/include --openssl-ssl-library=/opt/arm_openssl/lib --with-compiler-prefix=/home/liefyuan/rv1126/RV1126_RV1109_LINUX_SDK_V2.1.0_20210512/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-

配置的时候出现错误：bash: ./configure: /usr/bin/tclsh: bad interpreter: No such file or directory

liefyuan@ubuntu:~/rv1126/3th_lib/ffmpeg_lib/srt$ ./configure --prefix=/opt/arm_libsrt --openssl-include-dir=/opt/arm_openssl/include --openssl-ssl-library=/opt/arm_openssl/lib --with-compiler-prefix=/home/liefyuan/rv1126/RV1126_RV1109_LINUX_SDK_V2.1.0_20210512/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-
bash: ./configure: /usr/bin/tclsh: bad interpreter: No such file or directory

需要安装一下tclsh：apt install tclsh 配置就没有什么问题了。

然后编译、安装

make -j16
sudo make install

五、ffmpeg交叉编译

第一步配置：

./configure --prefix=/opt/arm_ffmpeg --enable-cross-compile --cross-prefix=/home/liefyuan/rv1126/RV1126_RV1109_LINUX_SDK_V2.1.0_20210512/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf- --arch=armv7-a --target-os=linux --enable-gpl --enable-nonfree --extra-cflags="-I/opt/arm_libx264/include" --extra-ldflags="-L/opt/arm_libx264/lib " --enable-libx264 --extra-libs="-ldl -fpic -shared" --enable-shared --pkg-config-flags=--static

这个配置编译安装以后，在安装目录生成arm_ffmpeg文件夹。

需要输出H265/PKG-CONFIG路径

export PKG_CONFIG_PATH=/opt/arm_libx265_install/lib/pkgconfig:$PKG_CONFIG_PATH
export PKG_CONFIG_PATH=/opt/arm_libx264/lib/pkgconfig:$PKG_CONFIG_PATH
export PKG_CONFIG_PATH=/opt/arm_libsrt/lib/pkgconfig:$PKG_CONFIG_PATH

Libx264和Libsrt交叉编译

./configure --prefix=/opt/arm32_ffmpeg_srt  --cross-prefix=/home/liefyuan/rv1126/RV1126_RV1109_LINUX_SDK_V2.1.0_20210512/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf- --enable-cross-compile --target-os=linux --cc=/home/liefyuan/rv1126/RV1126_RV1109_LINUX_SDK_V2.1.0_20210512/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc --arch=arm  --enable-shared --disable-static --enable-ffmpeg --extra-cflags=-I/opt/arm_libsrt/include --extra-cflags=-I/opt/arm_libx264/include --extra-ldflags=-L/opt/arm_libx264/lib --extra-ldflags=-L/opt/arm_libsrt/lib --enable-libx264 --enable-gpl --extra-libs="-lm -lsrt -lssl -ldl -lcrypto"


./configure --prefix=/opt/arm32_ffmpeg_srt  --cross-prefix=/home/liefyuan/rv1126/RV1126_RV1109_LINUX_SDK_V2.1.0_20210512/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf- --enable-cross-compile --target-os=linux --cc=/home/liefyuan/rv1126/RV1126_RV1109_LINUX_SDK_V2.1.0_20210512/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc --arch=arm  --enable-shared --disable-static --enable-ffmpeg --extra-cflags=-I/opt/arm_libsrt/include --extra-cflags=-I/opt/arm_libx264/include --extra-cflags=-I/opt/arm_libx265/include --extra-ldflags=-L/opt/arm_libx264/lib --extra-ldflags=-L/opt/arm_libx265/lib  --enable-libx264 --enable-libx265 --enable-gpl --pkg-config="pkg-config --static"


./configure --prefix=/opt/arm32_ffmpeg_srt  --cross-prefix=/home/liefyuan/rv1126/RV1126_RV1109_LINUX_SDK_V2.1.0_20210512/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf- --enable-cross-compile --target-os=linux --cc=/home/liefyuan/rv1126/RV1126_RV1109_LINUX_SDK_V2.1.0_20210512/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc --arch=arm  --enable-shared --disable-static --enable-ffmpeg --extra-cflags=-I/opt/arm_libsrt/include --extra-cflags=-I/opt/arm_libx264/include --extra-cflags=-I/opt/arm_libx265_install/include --extra-ldflags=-L/opt/arm_libx264/lib --extra-ldflags=-L/opt/arm_libx265_install/lib --extra-cflags=-I/opt/arm_libsrt/include --extra-ldflags=-L/opt/arm_libsrt/lib --enable-libsrt --enable-libx264 --enable-libx265 --enable-gpl --pkg-config="pkg-config --static" --extra-libs="-ldl"

建议使用第三个配置，最终编译安装后会在安装目录生成arm32_ffmpeg_srt文件夹

第二步：make

第三步：make install

编译出现的问题：
问题1：未定义closesocket，解决办法为在libavutil/timer.h中手动定义 #define closesocket(fd) close(fd)

libavformat/network.c: In function ‘ff_listen_bind’:
