hzs@ubuntu:~$ mkdir video_server hzs@ubuntu:~$ cd video_server/ 解压 ffmpeg-snapshot.tar.bz2，opencv-4.2.0.zip，video_server_linux.tar.gz，到/home/hzs/video_server
建议先把ubuntu设置中的镜像源改为阿里云的加快下载速度
一、安装ffmpeg： hzs@ubuntu:~/video_server$ cd ffmpeg hzs@ubuntu:~/video_server/ffmpeg$ pwd /home/hzs/video_server/ffmpeg
hzs@ubuntu:~/video_server/ffmpeg$ sudo apt-get update -qq && sudo apt-get -y install \ autoconf \ automake \ build-essential \ cmake \ git-core \ libass-dev \ libfreetype6-dev \ libsdl2-dev \ libtool \ libva-dev \ libvdpau-dev \ libvorbis-dev \ libxcb1-dev \ libxcb-shm0-dev \ libxcb-xfixes0-dev \ pkg-config \ texinfo \ wget \ zlib1g-dev
hzs@ubuntu:~/video_server/ffmpeg$ sudo apt-get install nasm
hzs@ubuntu:~/video_server/ffmpeg$ sudo apt-get install yasm
hzs@ubuntu:~/video_server/ffmpeg$ sudo apt-get install libx264-dev
hzs@ubuntu:~/video_server/ffmpeg$ sudo apt-get install libx265-dev libnuma-dev
hzs@ubuntu:~/video_server/ffmpeg$ sudo apt-get install libvpx-dev
hzs@ubuntu:~/video_server/ffmpeg$ sudo apt-get install libfdk-aac-dev
hzs@ubuntu:~/video_server/ffmpeg$ sudo apt-get install libmp3lame-dev
hzs@ubuntu:~/video_server/ffmpeg$ sudo apt-get install libopus-dev
hzs@ubuntu:~/video_server/ffmpeg$ ./configure \ --pkg-config-flags="--static" \ --prefix=/home/nvidia/ffmpeg_build \ --extra-libs="-lpthread -lm" \ --enable-shared \ --enable-gpl \ --enable-libx264
hzs@ubuntu:~/video_server/ffmpeg$ make -j12
hzs@ubuntu:~/video_server/ffmpeg$ sudo make install
hzs@ubuntu:~/video_server/ffmpeg$ sudo vi /etc/ld.so.conf
在文件中添加路径： /usr/local/lib
注意/usr/local/lib 目录是ffmpeg的安装目录，根据个人不同安装目录修改。
更新环境变量： hzs@ubuntu:~/video_server/ffmpeg$ sudo ldconfig
执行ffmpeg hzs@ubuntu:~/video_server/ffmpeg$ ffmpeg
出现以下内容证明安装成功 ffmpeg version N-95660-gfc7b6d5 Copyright (c) 2000-2019 the FFmpeg developers built with gcc 5.4.0 (Ubuntu 5.4.0-6ubuntu1~16.04.9) 20160609 configuration: --pkg-config-flags=--static --extra-libs='-lpthread -lm' --enable-shared --enable-gpl --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-nonfree libavutil 56. 35.101 / 56. 35.101 libavcodec 58. 60.100 / 58. 60.100 libavformat 58. 34.101 / 58. 34.101 libavdevice 58. 9.100 / 58. 9.100 libavfilter 7. 66.100 / 7. 66.100 libswscale 5. 6.100 / 5. 6.100 libswresample 3. 6.100 / 3. 6.100 libpostproc 55. 6.100 / 55. 6.100 Hyper fast Audio and Video encoder usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...
Use -h to get full help or, even better, run 'man ffmpeg'
三、编译video_server
进入video_server_linux/3rdparty/jsoncpp-src-0.6.0-rc2 文件夹中，按照README.txt的文档操作，编译jsoncpp
hzs@ubuntu:~/video_server/opencv-4.2.0/build$ cd ../../video_server_linux/3rdparty/jsoncpp-src-0.6.0-rc2/ hzs@ubuntu:~/video_server/video_server_linux/3rdparty/jsoncpp-src-0.6.0-rc2$ python scons.py platform=linux-gcc （注意是python 不是python3）
编译好jsoncpp后在当前文件夹会出现libs/linux-gcc-5.4.0文件夹，然后将linux-gcc-5.4.0文件夹中的文件添加到/usr/local/lib中 hzs@ubuntu:~/video_server/video_server_linux/3rdparty/jsoncpp-src-0.6.0-rc2$ cd libs/linux-gcc-5.4.0/ hzs@ubuntu:~/video_server/video_server_linux/3rdparty/jsoncpp-src-0.6.0-rc2/libs/linux-gcc-5.4.0$ sudo cp libjson_linux-gcc-5.4.0_libmt.* /usr/local/lib/
hzs@ubuntu:~$ cd /home/hzs/video_server/video_server_linux hzs@ubuntu:~/video_server/video_server_linux$ sudo apt-get install libboost1.58-all-dev
hzs@ubuntu:~/video_server/video_server_linux$ cd build/
先清空此文件夹 hzs@ubuntu:~/video_server/video_server_linux/build$ rm -rf *
hzs@ubuntu:~/video_server/video_server_linux/build$ cmake .. hzs@ubuntu:~/video_server/video_server_linux/build$ make ... [100%] Linking CXX executable video_server [100%] Built target video_server
执行video_server hzs@ubuntu:~/video_server/video_server_linux/build$ ./video_server Hello World! 开启视频流服务器，正在等在连接...
然后再windwos中打开test_video_server文件夹，修改dist/wfs.js中的第602行ar client = new WebSocket('ws://192.168.59.129:9002');中的IP地址，地址为video_server运行的ubuntu的IP地址，端口号可以在main.cpp中修改对应即可 最后双击打开playvmwarelinux.html可以预览即可，文件中有摄像头的地址，可以修改
