onvif获取rtsp地址流程
1.搜索Probe，设备发现，发现IPC，获取webService地址；
2.获取能力集，GetCapabilities，从中识别出媒体信息地址URI：http://192.168.73.231:8080/onvif/media_service
3.获取媒体信息，GetProfiles，获取媒体信息文件，识别主通道、子通道的视频编码分辨率
4.获取RTSP地址，GetStreamUri，获取指定通道的流媒体地址

使用github.com/use-go/onvif包，实现go语言对接onvif协议

利用gSoap生成ONVIF Server框架

服务器端 UDP socket，监听239.255.255.250：3702

IPC工作原理:
首先，进程A获取来自AR0330摄像头模块的YUV原始视频图像，并使用H265压缩编码算法进行压缩编码获 得H265格式码流，该过程通过使用海思提供的媒体处理平台（MPP）实现；

其次，进程B负责响应网络客户端的请求，将进程A的输出码流通过千兆以太网接 口实时地发送出去，该过程通过对LIVE555开源代码（该代码原本只支持文件发送功能，而不支持内存实时数据发送功能）二次开发实现；
整体流程：

Probe： 发现网络摄像头，获取webserver地址 http://192.168.15.240/onvif/device_service

GetCapabilities：获取设备能力文件，从中识别出媒体信息地址URI： http://192.168.15.240/onvif/Media

GetProfiles： 获取媒体信息文件，识别主通道、子通道的视频编码分辨率

GetStreamUri：获取指定通道的流媒体地址 rtsp://192.168.15.240:554/Streaming/Channels/2?transportmode=unicast

onvif 设备发现的机制
从ONVIF的官方文档中可以了解到，客户端在UDP协议下，向网段内的组播地址239.255.255.250，端口3702，不断地向四周发送Probe消息探针，而网段内的服务器在接收到Probe这个探测消息后，通过回复ProbeMatch消息让客户端接收，从而让客户端识别到服务器。

所以服务器端就需要创建一个UDP协议的socket，去监听239.255.255.250：3702，接收到客户端的Probe探针后，进行响应，从而让客户端识别到onvif服务器。

通过抓包,发现probe的包内容
通过udp工具发送出去也是可以的.

使用Ubuntu 20 编译 aarch64 版本的QT

编译命令

sudo apt install gcc-aarch64-linux-gnu g++-aarch64-linux-gnu build-essential
tar xvf qt-everywhere-opensource-src-5.15.9.tar.xz
cd qt-everywhere-opensource-src-5.15.9
mkdir build
cd build/

../configure -prefix /opt/aarch64 -make libs -xplatform linux-aarch64-gnu-g++ -no-opengl
make -j2
sudo make install

然后就将相应的库安装到/opt/aarch64目录下面了.

Ubuntu编译OpenGL程序示例
之所以在这里引入OpenGL,是因为,咱们在编译QT的时候,没有编译opengl,如果这里可以成功,我们可以使用sysroot的方式引入opengl库,从而交叉编译成功支持opengl的qt库.

sudo apt update
sudo apt install libglu1-mesa-dev freeglut3-dev mesa-common-dev
vi main.cpp

程序源代码:

#include <GL/glut.h>
void displayMe(void)
{
    glClear(GL_COLOR_BUFFER_BIT);
    glBegin(GL_POLYGON);
        glVertex3f(0.5, 0.0, 0.5);
        glVertex3f(0.5, 0.0, 0.0);
        glVertex3f(0.0, 0.5, 0.0);
        glVertex3f(0.0, 0.0, 0.5);
    glEnd();
    glFlush();
}

int main(int argc, char** argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_SINGLE);
    glutInitWindowSize(400, 300);
    glutInitWindowPosition(100, 100);
    glutCreateWindow("Hello world!");
    glutDisplayFunc(displayMe);
    glutMainLoop();
    return 0;
}

编译命令:

g++ main.cpp -o firstOpenGlApp -lglut -lGLU -lGL
./firstOpenGlApp

运行效果:

Qt5.15就不支持下载安装包了,只能自己编译或者apt安装了.最后的下载地址:

Ubuntu Qt交叉编译环境的搭建

经过测试,发现并没有编译qtwebengin,检查发现,还需要其他一些东西

sudo apt install gperf bison flex python2 nodejs

后面又安装了libclang-dev

安装完这些东西后,又提示没有指定sysroot,所以不能够编译webengine.哪就来指定sysroot吧.在本机的设备机上都安装rsync
sudo apt install rsync

然后在虚拟机上,创建sysroot目录
mkdir -p ~/sysroot/usr
mkdir -p ~/sysroot/lib
cd ~
rsync -avz --rsync-path="rsync" --delete root@192.168.4.202:/lib sysroot/lib
rsync -avz --rsync-path="rsync" --delete root@192.168.4.202:/usr/include sysroot/usr
rsync -avz --rsync-path="rsync" --delete root@192.168.4.202:/usr/lib sysroot/usr

根据实际ip，修改上面的192.168.4.202,注意第一行,可能要修改一下,因为原来的/lib目录就是一个软链接,所以在sysroot/lib里面要相应修改一下.

修改configure命令

PKG_CONFIG_LIBDIR=/home/hesy/sysroot/usr/lib/aarch64-linux-gnu/pkgconfig ../configure -prefix /opt/aarch64 -make libs -xplatform linux-aarch64-gnu-g++ -sysroot /home/hesy/sysroot -webengine-webrtc

现在只有一个警告了.No wayland-egl support detected

Note: Also available for Linux: linux-clang linux-icc

Note: PKG_CONFIG_SYSROOT_DIR automatically set to /home/hesy/sysroot

Note: No wayland-egl support detected. Cross-toolkit compatibility disabled.

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/home/hesy/sysroot/opt/aarch64'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

查看webengine相关的选项, 发现alsa, pulseaudio等都没有编译,这个应该要加进去.
./configure -h |grep webengine

-webengine-alsa -webengine-pulseaudio -system-ffmpeg -webengine-opus -webengine-webp

另外,好像SSL也没有编译进去,也需要打开.使用--openssl-linked加上OPENSSL_LIBS二个选项就可以打开ssl了.

不知道改了什么,反正用下面这个就好了.有可能改了sysroot/lib的软链接出来.

OPENSSL_LIBS='-L/home/hesy/sysroot/usr/lib/aarch64-linux-gnu -lssl -lcrypto'  PKG_CONFIG_LIBDIR=/home/hesy/sysroot/usr/lib/aarch64-linux-gnu/pkgconfig ../configure -prefix /opt/aarch64 -make libs -xplatform linux-aarch64-gnu-g++ -sysroot /home/hesy/sysroot -webengine-webrtc  -webengine-pulseaudio -qt-ffmpeg -qt-opus -qt-webp -openssl-linked -I/home/hesy/sysroot/usr/include -L/home/hesy/sysroot/usr/lib/aarch64-linux-gnu

提示信息如下:
Note: Also available for Linux: linux-clang linux-icc

Note: PKG_CONFIG_SYSROOT_DIR automatically set to /home/hesy/sysroot

Note: No wayland-egl support detected. Cross-toolkit compatibility disabled.
直接忽略掉了.
make 试下

中间遇到undefined reference to _dl_stack_flags之类的错误,发现sysroot/lib/里面的libpthread.so的软链接路径不对,导致直接链接的是libpthread.a静态库,所以报了这个错误.

出现错误:
error: static assertion failed: Required feature library for file /home/hesy/qt5/qtbase/include/QtCore/../../src/corelib/plugin/qlibrary.h not available.
121 | # define Q_STATIC_ASSERT_X(Condition, Message) static_assert(bool(Condition), Message)

在排查上面的问题的时候,发现了sysroot/lib目录下有很多软连接不正确,顺带修改一下.
ln -snf libBrokenLocale.so.1 libBrokenLocale.so

使用Qt5.12.9来编译,还是会出现这个错误,感觉像是openssl的问题.但不确定.

再换Qt5.15.11来编译验证.

之所以这么试,是看到网上有人说,重新解压源码来编译就没问题了.

试了下下,果然编译通过了.不明觉厉.

make install

出现错误:
cannot find -lqt_clip2tri

重新编译,出现错误:
fatal error: wayland-client.h: No such file or directory
26 | #include <wayland-client.h>

安装相应的包
sudo apt install -y libwayland-dev
重新编译,出现错误
undefined reference to `__pointer_chk_guard_local'

检查发现,又是链接了libthread.a静态库的原因,软连接坏了,修复一下.

编译到后期的时候,会出现资源不够用情况,使用命令禁用一些cpu核心,来保证编译正常运行.

For example, if you have a 12 core and 16 GB RAM, you can disable last 6 core with:

sudo chcpu --disable 6-11

And start make process which will be execute ninja later. In this setup ninja is going to use total of 8 parallel jobs (6+2). After a while (lets say 30 seconds), you can enable the cpus like below:

sudo chcpu --enable 6-11

to continue working while QtWebEngine build running.

使用了上面的办法,还是老是死机,没办法了,修改ninja.cc源码,将进程数据+2直接改为-1

重新configure

OPENSSL_LIBS='-L/home/hesy/sysroot/usr/lib/aarch64-linux-gnu -lssl -lcrypto'  PKG_CONFIG_LIBDIR=/home/hesy/sysroot/usr/lib/aarch64-linux-gnu/pkgconfig ../configure -prefix /opt/aarch64 -make libs -xplatform linux-aarch64-gnu-g++ -sysroot /home/hesy/sysroot -webengine-webrtc  -webengine-pulseaudio -qt-ffmpeg -qt-opus -qt-webp -openssl-linked -I/home/hesy/sysroot/usr/include -L/home/hesy/sysroot/usr/lib/aarch64-linux-gnu

Qt will be installed into '/home/hesy/sysroot/opt/aarch64'.

8:53开始编译
3个小时左右能够编译完成.

运行的时候报缺少qba-xcb的错误.

qtwebengine不能播放mp4的问题.

[1093:1112:1127/003829.439019:ERROR:batching_media_log.cc(26)] MediaEvent: MEDIA_ERROR_LOG_ENTRY {"error":"FFmpegDemuxer: no supported streams"}

上面的操作始终都不能够编译成功qtwebengine带qpa-xcb,重新来一次.
查看qt5.15的系统依赖. https://doc.qt.io/qt-5.15/linux-requirements.html
在ubuntu20.04上安装下面包

sudo apt install libfontconfig1-dev libfreetype6-dev libx11-dev libx11-xcb-dev libxext-dev libxfixes-dev libxi-dev libxrender-dev libxcb1-dev libxcb-glx0-dev libxcb-keysyms1-dev libxcb-image0-dev libxcb-shm0-dev libxcb-icccm4-dev libxcb-sync-dev libxcb-xfixes0-dev libxcb-shape0-dev libxcb-randr0-dev libxcb-render-util0-dev libxcb-xinerama0-dev libxkbcommon-dev libxkbcommon-x11-dev libatspi2.0-dev

sudo apt install libxcomposite-dev libdrm-dev libxcursor-dev libxi-dev libxrandr-dev libxtst-dev libxdamage-dev libxss-dev libxkbfile-dev

sudo apt install libavcodec-dev libavformat-dev libavutil-dev
sudo apt install libopus-dev libwebp-dev libvpx-dev

执行了这些安装包后,使用configure是能够把qtwebengine给包进去了.

最简单的configure

../configure -opensource -confirm-license -webengine-ffmpeg
make -j5

9:21开始编译,看看有没有什么问题.

通过将/usr/share/pkgconifg的*.pc文件复制到/usr/lib/pkgconfig目录后,可以交叉编译了.

OPENSSL_LIBS='-L/home/hesy/sysroot/usr/lib/aarch64-linux-gnu -lssl -lcrypto'  PKG_CONFIG_LIBDIR=/home/hesy/sysroot/usr/lib/aarch64-linux-gnu/pkgconfig ../configure -prefix /opt/aarch64 -make libs -xplatform linux-aarch64-gnu-g++ -sysroot /home/hesy/sysroot -webengine-webrtc  -webengine-pulseaudio -no-eglfs -recheck-all -webengine-opus -webengine-ffmpeg -webengine-proprietary-codecs -openssl-linked -I/home/hesy/sysroot/usr/include -L/home/hesy/sysroot/usr/lib/aarch64-linux-gnu

上面的命令是可以正确配置的,试下下面这个.

../configure -prefix /opt/aarch64 -make libs -xplatform linux-aarch64-gnu-g++ -sysroot /home/hesy/sysroot -webengine-webrtc  -webengine-pulseaudio -no-eglfs -recheck-all -webengine-opus -webengine-ffmpeg -webengine-proprietary-codecs -opensource -confirm-license

经过验证,直接使用上面的命令就可以配置成功了.剩下的就是几个小时的编译了.

配置后输出信息汇总如下:

Note: Also available for Linux: linux-clang linux-icc

Note: PKG_CONFIG_LIBDIR automatically set to /home/hesy/sysroot/usr/lib/pkgconfig:/home/hesy/sysroot/usr/share/pkgconfig:/home/hesy/sysroot/usr/lib/aarch64-linux-gnu/pkgconfig

Note: PKG_CONFIG_SYSROOT_DIR automatically set to /home/hesy/sysroot

Note: No wayland-egl support detected. Cross-toolkit compatibility disabled.

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/home/hesy/sysroot/opt/aarch64'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

开始编译:

make -j4 && make install

发现一个坑的地方,如果加上recheck-all选项,在每次编译出错的时候,修改了错误或者增加了新的包后,make的时候就会从头开始编译,这太费时间了. 所以下面的配置去掉了--recheck-all

../configure -prefix /opt/aarch64 -make libs -xplatform linux-aarch64-gnu-g++ -sysroot /home/hesy/sysroot -webengine-webrtc  -webengine-pulseaudio -no-eglfs -webengine-opus -webengine-ffmpeg -webengine-proprietary-codecs -opensource -confirm-license

make -j8

15.25开始编译,半个小时能到qtwebengine的样子.

上面是能够编译成功的xcb 的配置,但是要使用gpu还是得编译上eglfs,要使eglfs mail 变成yes

编译命令如下

../configure -prefix /opt/aarch64 -make libs -xplatform linux-aarch64-gnu-g++ -sysroot /home/hesy/sysroot -webengine-webrtc  -webengine-pulseaudio  -webengine-opus -webengine-ffmpeg -webengine-proprietary-codecs -opensource -confirm-license

提示了一个fbdev_windows.h没有的错误,手动建立一下.

重新configure ,然后就可以了.配置好后的输出

开始编译,因为有8个cpu,咱们保守点,就用7个吧.

make -j7

大约半个小时能到qtwebengine,这个时候为了防止死机,一是加上交换内存,一个disable cpu数量.

增加swap空间
1.查看当前系统swap空间

free -m

2.增加swap文件

dd if=/dev/zero of=/swap/swapfile bs=1M count=8096

3.查看创建文件大小

du -sh /swap/swapfile

4.将目标文件标识为swap分区文件

mkswap /swap/swapfile

5.激活swap文件

swapon /swap/swapfile

6.修改/etc/fstab文件，在末行增加以下内容

vim /etc/fstab
/swap/swapfile swap swap defaults 0 0

7.查看是否挂载成功

出现错误:
cc1: error: one or more PCH files were found, but they were invalid
重新configure ,重新make

Qt可以通过窗口系统显示（x11，wayland），也可以直接显示通过一些插件，如QT EGLFS。
EGLFS是一个平台插件，可以在EGL和OpenGL ES之上运行Qt应用程序，而不需要通过X11或Wayland这样的实际窗口系统。

rk356x eglfs gbm x11 wayland

运行Qt程序，通过QPA（Qt Platform Abstraction）平台抽象显示，不同平台显示可以使用不同QPA插件， 一般Qt将根据平台选择一个默认的QPA插件（可以交叉编译库时configure配置）， 也可以设置QT_QPA_PLATFORM环境变量或者-PLATFORM命令行参数选择不同的平台插件。

一般使用平台插件后端有：eglfs（需要OpenGL/EGL图形栈）、linuxfb（帧缓冲区接口）、 wayland和xcb（x11）。

linuxfb插件通过Linux的fbdev子系统直接写入帧缓冲区，不支持硬件渲染，显示性能可能会不好。 eglfs是qt自己实现的一个gui显示插件，eglfs使用opengles/egl进行gpu渲染后，直接送给drm去显示（使用opengles、egl接口，安装gbm或者x11-gbm版的libmali）

快速验证测试,不编译webengine

../configure -prefix /opt/aarch64 -make libs -xplatform linux-aarch64-gnu-g++ -sysroot /home/hesy/sysroot1 -skip webengine -eglfs -recheck-all -opensource -confirm-license -opengl es2

apt install libgbm-dev libwayland*

9.06开始编译

在提示gbm version.h文件在global path找不到的时候,直接在编译机上安装libgbm-dev居然能解决.

使用ubuntu 20.04编译qt5.15.10

../configure -prefix /opt/aarch64 -make libs -xplatform linux-aarch64-gnu-g++ -sysroot /home/hesy/sysroot -kms -eglfs -opensource -confirm-license -opengl es2 -I/home/hesy/sysroot/usr/include -v -webengine-webrtc -webengine-pulseaudio -qt-ffmpeg -qt-opus -qt-webp

libvpx如果没打开，提示VPX_IMG_FMT_NV12未定义的错误的话
在/usr/include/vpx/vpx_image.h中添加

Note: PKG_CONFIG_LIBDIR automatically set to /home/hesy/sysroot/usr/lib/pkgconfig:/home/hesy/sysroot/usr/share/pkgconfig:/home/hesy/sysroot/usr/lib/aarch64-linux-gnu/pkgconfig

Note: PKG_CONFIG_SYSROOT_DIR automatically set to /home/hesy/sysroot

WARNING: QDoc will not be compiled, probably because libclang could not be located. This means that you cannot build the Qt documentation.

Either ensure that llvm-config is in your PATH environment variable, or set LLVM_INSTALL_DIR to the location of your llvm installation.
On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution.
On macOS, you can use Homebrew's llvm package.
On Windows, you must set LLVM_INSTALL_DIR to the installation path.

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/home/hesy/sysroot/opt/aarch64'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

make

添加 Qt 的软件源

sudo add-apt-repository ppa:beineri/opt-qt-5.15.0-focal

此命令会向 Ubuntu 的 package manager 中添加 Qt 的软件源。

更新软件包列表

sudo apt-get update

安装 Qt

sudo apt-get install qt515base qt515charts-no-lgpl qt515connectivity qt515graphicaleffects qt515imageformats qt515quickcontrols qt515quickcontrols2 qt515svg qt515tools qt515translations qt515wayland qt515websockets qt515webview

也可以这样:

sudo apt-get install qt5*

以上命令会安装 Qt 5.15 版本和相关组件。

请注意，以上示例中的命令是用于安装 Qt 5.15 的，你可以根据自己的需求，替换软件源中的版本号进行安装。

最后，你可以通过以下命令验证是否安装成功：

qmake -v

该命令会显示已安装的 Qt 版本信息。
