• "Error : FFMPEG not found" : Error with simple Discord Bot

  23 décembre 2019, par Robin Seerig

  I’m using Windows (64-bit) with Node.js and npm installed.
  In my project file, I have run the following commands :

  npm init
  
  npm install discord.js --save
  
  npm install ffmpeg --save

  Now i just created the code for a basic bot here is the main code.
  I list here the important :

   if (message.content === '!play' && message.member.roles.has(message.guild.roles.find("name", config.role_name).id)) {
  
      if (!message.member.voiceChannel) return log("?");
  
         message.member.voiceChannel.join().then(function (connection){      
  
         });
  
   }

  Then, in Discord, I say the following :

   [1517932146]  Musik bot loaded
  
      (node:35760) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): Error: FFMPEG not found

  I have already tested the following :

  • reinstallation of everything
  • others of the require names e.t.z.
  • simplify the code

  So if you have any ideas then let me know.

  Solution

  npm i ffmpeg-binaries@3.2.2-3

• How to fix opencv python cv2.VideoCapture rtsp onvif "nonmatching transport in server reply" error ?

  28 juillet 2022, par Projetos Prince Tower

  I am on Windows and using Python 3.6.4. I've installed OpenCV (3.4) via pip. Here is the code I am using :

  


  import numpy as np
import cv2

cap = cv2.VideoCapture('rtsp://192.168.15.116:554/onvif1')

while(cap.isOpened()):
    ret, frame = cap.read()

    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

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

cap.release()
cv2.destroyAllWindows()


  


  I am getting the following error :

  


  [rtsp @ 03858a40] Nonmatching transport in server reply
warning: Error opening file (/build/opencv/modules/videoio/src/cap_ffmpeg_impl.hpp:808)
warning: rtsp://192.168.15.116:554/onvif1 (/build/opencv/modules/videoio/src/cap_ffmpeg_impl.hpp:809)


  


  I can go to cmd and type

  


  ffplay rtsp://192.168.15.116/onvif1


  


  and the video will run as well as in VLC using the same rtsp address. Using

  


  cv2.VideoCapture(0)


  


  also works with my webcam.

  


  I've tried copying the file "opencv_ffmpeg340.dll" into all path folders but to no avail. I've also checked build and all video I/O show up with "YES" except for Gstreamer. Any help would be appreciated.
Thank you.
