使用flask apche2和wsgi服务器在raspberrypi上进行视频串流 [英] Video Straming on raspberrypi using flask apche2and wsgi server

问题描述

我使用了 Flask 应用程序通过 raspberrypi 相机串流视频.我用于烧瓶应用程序的代码在这里:https://blog.miguelgrinberg.com/post/video-streaming-with-烧瓶

I have used flask app for straming video via raspberrypi camera. The code i used for flask app is here: https://blog.miguelgrinberg.com/post/video-streaming-with-flask

在本地服务器上它正在播放视频流，但不在我的网站上.

In local server it is doing video stream but not on my website.

我正在使用具有 wsgi 文件的 apache2 服务器:

I am using apache2 server having wsgi file below:

flaskapp2.wsgi

flaskapp2.wsgi

#!/usr/bin/python
import sys  
import logging  
logging.basicConfig(stream=sys.stderr)   
sys.path.insert(0,"/var/www/FlaskApp2/FlaskApp2")  
from ashish import app as application  
application.secret_key ='1233883'

文件系统的结构是:

/var/www/FlaskApp2/
    flskapp2.wsgi
    FlaskApp2/
        ashish.py
        camera_pi.py
        templates/index.html  

ashish.py 是正在执行流的烧瓶应用程序.

The ashish.py is the flask app which is doing stream.

apache中的错误日志文件为:

The error log file in apache is:

在本地主机上它可以工作，但在我的网站上却没有，wsgi 文件中是否有任何错误，或者我需要添加一些内容.

On localhost it is working but not on my website is there any mistake in wsgi file or i need to add something.

推荐答案

我的整个文件配置是正确的，但是当我在 apache 服务器下运行 Flask 应用程序时，apache 无法访问 pi 摄像头，因为它没有 root 访问权限到 pi.so，在本地服务器上它正在运行，但在我的网站上运行时却没有在 apache 上运行.

My whole configuration of files were right but as i was running flask applications under apache server ,apache was not able to acess pi camera because it was not having root access to pi.so,on local server it was working but not on my website when it was running on apache.
