• How to run ffmpeg on demand when someone opens my website with the player where a remote IP camera is displayed ?

  8 mai 2023, par alexiter

  I set up an nginx server to stream from an IP camera located elsewhere, I used a windows server because it was the one I had no use for (I usually prefer linux), I would need to know how I can make the ffmpeg command run only when someone opens the website where the player is located.

  


  This is my nginx.conf server code :

  


  worker_processes  1;

error_log  logs/error.log info;

events {
    worker_connections  1024;
}
rtmp {
    server {
        listen 1935;
        ping 30s;
        notify_method get;
        application live {
            live on;
            on_publish http://*******:8080/auth;
            dash on; 
            dash_path tmp/dash;
            
            
        }
    }
}
http{

   server {
        listen 8080;
        location /auth {
        if ($arg_psk = '*****') {
    return 201;
    }
  return 404;
  }
}
   
   server {
        listen 8443 ssl;
        server_name stream.*****.com;
        
        ssl on;
        ssl_certificate C:/Certbot/live/stream.*****.com/fullchain.pem;
        ssl_certificate_key C:/Certbot/live/stream.****.com/privkey.pem;
        ssl_session_timeout 5m;
        charset utf-8;
        location /dash {
            root tmp;
            add_header Cache-Control no-cache;
        }
        location / {
            root www;
        }
        

   }
}



  


  The command that I use from the DOS console in windows is this :

  


  ffmpeg -rtsp_transport tcp -i rtsp://*****:******@******.com:557/Streaming/Channels/101 -c copy -f flv -y -t 35 rtmp://********:1935/live/stream?psk=********


  


  Basically what I need is that ffmpeg is not running constantly, only when someone wants to view the video from the IP camera. (I have programmed ffmpeg to finish after 35 seconds, although I will put five minutes later)

  


• Send data to udp port in azure virtual machine

  30 août 2013, par Anton Shakalo

  I use Wowza for live video streaming solution. I prefer to use windows azure as cloud hosting.

  For video streaming I need to open some udp ports.
  I have created endpoint for udp port 10000, map private and public ports to 10000 following instructions from here.

  I repeat this for http/80 port and it works fine.

  Then I tried to send video stream by ffmpeg with next command :

  ffmpeg -re -i "%WMSAPP_HOME%/content/sample.mp4"  -vcodec libx264  -vb 150000 -g 60 -vprofile baseline -level 2.1 -acodec aac -ab 64000 -ar 48000 -ac 2 -vbsf h264_mp4toannexb -strict experimental -f mpegts udp://%SERVER_IP%:10000?pkt_size=1316

  Where %SERVER_IP% is public IP address of my virtual machine.
  When I test locally, with 127.0.0.1 as server url, streaming works without problems.
  But now I can not see that video stream is coming to server.

  So I need help with this. How can I send data to udp port in azure virtual machine ?

  Also, I've tried to ping %SERVER_IP%:%PORT% by telnet and nmap but no success.
  If I describe something not clear on not correct - please comment and I will try to explain more detail.

• OpenCV cant open rtsp stream of hikvision cameras ?

  25 août 2022, par Smadar

  I'm using hikvision camera, and tried to open the rtsp stream using OpenCV videoCapture with cv2.CAP_FFMPEG, but OpenCV failed to open it.
I open the stream from VLC and it is working fine.
The configuration parameters in the camera dashboard was changed as well. The encoding parameter was changed from H265 to H264, the resolution also has changed to a lower values (1280*720 - the lowest, also tried full HD), the bitrate was changed as well .
I tried to open the stream in two ways -
The first way :

  


  feed = cv2.VideoCapture('rtsp://user:password@IP:554/Streaming/Channels/1', cv2.CAP_FFMPEG)
print('FEED IS OPEN ? ', feed.isOpened())
if feed.isOpened():
    print('IM HERE')
    frame_status, frame = feed.read()
    print(frame_status)
    print(frame.shape[0])


  


  The second way :

  


  cap = cv2.VideoCapture()

cap.open("rtsp://user:password@IP:554/Streaming/Channels/1")
print('IM HERE', cap.isOpened())
while(True):
     # Capture frame-by-frame
    print('IM HERE')
    ret, frame = cap.read()
    print('RET: ', ret)
    print(type(frame))
    print('IM HERE')
    # Our operations on the frame come here
    #gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

    # Display the resulting frame
    print(frame.shape[0])
    # cv2.imshow('frame',ret)

    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

# When everything done, release the capture
cap.release()
cv2.destroyAllWindows()


  


  There is also check ping and there is a connection to the camera.

  


  I will really appreciate any help here in trying of figure this out.
Thank you all.
