【树莓派5 测评】 + 13.视频推流功能测试（zmj）

树莓派5 的USB摄像头（UVC）借助mjpg-streamer实现网页监控推流十分便捷（电脑、手机均可以正常访问）。

---------------------------以下为正文---------------------------

1.        mjpg-streamer下载及编译

下载编译流程如下：

1. //------mjpg-streamer
   
2. //---下载
   
3. git clone https://github.com/jacksonliam/mjpg-streamer.git
   
4. cd mjpg-streamer
   
5. cd mjpg-streamer-experimental
   
6. gcc -v
   
7. //---依赖项/依赖库的安装
   
8. sudo apt install cmake
   
9. sudo apt-get install -y cmake libjpeg62-turbo-dev
   
10. //---编译安装mjpg-streamer（需要sudo权限才能安装）
    
11. sudo apt install cmake
    
12. make all
    
13. sudo make install  
    
14. //---测试指令
    
15. sudo /usr/local/bin/mjpg_streamer -i "input_uvc.so -d /dev/video0 -r 1280x720 -y" -o "output_http.so"
    
16. 部分测试配置（自动）如下所示：
    
17.         设备：/dev/video0
    
18.         分辨率：1280*720（720P）
    
19.         帧率：1帧/秒（此种情况下节省网络带宽，降低CPU占用率）
    
20.         格式：YUYV
    
21.         端口：8080
    
22. //---访问方式（PC端和手机端均OK，IP地址是：192.168.5.177）：
    
23. http://192.168.5.177:8080/?action=stream

复制代码

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，同一局域网内在PC端和手机端均能正常查看推流效果。

1. //---测试指令
   
2. sudo /usr/local/bin/mjpg_streamer -i "input_uvc.so -d /dev/video0 -r 1280x720 -y" -o "output_http.so"
   
3. 部分测试配置（自动）如下所示：
   
4.         设备：/dev/video0
   
5.         分辨率：1280*720（720P）
   
6.         帧率：1帧/秒（此种情况下节省网络带宽，降低CPU占用率）
   
7.         格式：YUYV
   
8.         端口：8080
   
9. //---访问方式（PC端和手机端均OK）：
   
10. A.家中IP地址是：192.168.1.103
    
11. http://192.168.1.103:8080/?action=stream

17. > ./mjpg_streamer -h
    
18. -----------------------------------------------------------------------
    
19. Usage: ./mjpg_streamer
    
20.   -i | --input "<input-plugin.so> [parameters]"
    
21.   -o | --output "<output-plugin.so> [parameters]"
    
22. [-h | --help ]........: display this help
    
23. [-v | --version ].....: display version information
    
24. [-b | --background]...: fork to the background, daemon mode
    
25. -----------------------------------------------------------------------
    
26. Example #1:
    
27. To open an UVC webcam "/dev/video1" and stream it via HTTP:
    
28.   ./mjpg_streamer -i "input_uvc.so -d /dev/video1" -o "output_http.so"
    
29. -----------------------------------------------------------------------
    
30. Example #2:
    
31. To open an UVC webcam and stream via HTTP port 8090:
    
32.   ./mjpg_streamer -i "input_uvc.so" -o "output_http.so -p 8090"
    
33. -----------------------------------------------------------------------
    
34. Example #3:
    
35. To get help for a certain input plugin:
    
36.   ./mjpg_streamer -i "input_uvc.so --help"
    
37. -----------------------------------------------------------------------
    
38. In case the modules (=plugins) can not be found:
    
39. * Set the default search path for the modules with:
    
40.    export LD_LIBRARY_PATH=/path/to/plugins,
    
41. * or put the plugins into the "/lib/" or "/usr/lib" folder,
    
42. * or instead of just providing the plugin file name, use a complete
    
43.    path and filename:
    
44.    ./mjpg_streamer -i "/path/to/modules/input_uvc.so"
    
45. -----------------------------------------------------------------------
