【VisionFive 2：集成3D GPU RISC-V单板计算机】+10.视频推流测试（zmj）

赛昉科技“昉·星光 2”开发板的USB摄像头（UVC）借助mjpg-streamer实现网页监控推流十分便捷。

1. 下载编译

下载编译流程如下：

//------mjpg-streamer
//---下载
git clone https://github.com/jacksonliam/mjpg-streamer.git
cd mjpg-streamer
cd mjpg-streamer-experimental
gcc -v
//---依赖项/依赖库的安装
sudo apt install cmake
sudo apt-get install -y cmake libjpeg62-turbo-dev
//---编译安装mjpg-streamer
sudo apt install cmake
make all
make install
//---测试指令
sudo /usr/local/bin/mjpg_streamer -i "input_uvc.so -d /dev/video0 -r 1280x720 -y" -o "output_http.so"
部分测试配置（自动）如下所示：
	设备：/dev/video0
	分辨率：1280*720（720P）
	帧率：1帧/秒（此种情况下节省网络带宽，降低CPU占用率）
	格式：YUYV
	端口：8080
//---访问方式（PC端和手机端均OK）：
http://192.168.100.200:8080/?action=stream

2. 测试结果

最终呈现效果是网页端实时刷新（1帧/秒）摄像头结果，统一局域网内在PC端和手机端均能正常查看推流效果。

user@starfive:~/zmj_ws/gst/mjpg-streamer/mjpg-streamer-experimental$ \
> ./mjpg_streamer -h
-----------------------------------------------------------------------
Usage: ./mjpg_streamer
  -i | --input "<input-plugin.so> [parameters]"
  -o | --output "<output-plugin.so> [parameters]"
 [-h | --help ]........: display this help
 [-v | --version ].....: display version information
 [-b | --background]...: fork to the background, daemon mode
-----------------------------------------------------------------------
Example #1:
 To open an UVC webcam "/dev/video1" and stream it via HTTP:
  ./mjpg_streamer -i "input_uvc.so -d /dev/video1" -o "output_http.so"
-----------------------------------------------------------------------
Example #2:
 To open an UVC webcam and stream via HTTP port 8090:
  ./mjpg_streamer -i "input_uvc.so" -o "output_http.so -p 8090"
-----------------------------------------------------------------------
Example #3:
 To get help for a certain input plugin:
  ./mjpg_streamer -i "input_uvc.so --help"
-----------------------------------------------------------------------
In case the modules (=plugins) can not be found:
 * Set the default search path for the modules with:
   export LD_LIBRARY_PATH=/path/to/plugins,
 * or put the plugins into the "/lib/" or "/usr/lib" folder,
 * or instead of just providing the plugin file name, use a complete
   path and filename:
   ./mjpg_streamer -i "/path/to/modules/input_uvc.so"

视频推流测试主要看的是否流畅，看楼主的视频刷新1帧/秒效果还行吧

 

recheck

推出的视频流是什么协议的？HLS还是rtmp，还是可以选配协议
