  I'm trying to merge the prerecorded videos using python Opencv.
But i'm getting the error while importing.

  



  "Traceback (most recent call last):&#xA;  File "video.py", line 4, in <module>&#xA;    from moviepy. editor import VideoFileClip,concatenate_videoclips &#xA;  File "/home/pi/.virtualenvs/cv/lib/python3.5/site-packages/moviepy/editor.py", line 26, in <module>&#xA;    imageio.plugins.ffmpeg.download()&#xA;  File "/home/pi/.virtualenvs/cv/lib/python3.5/site-packages/imageio/plugins/ffmpeg.py", line 40, in download&#xA;    "imageio.ffmpeg.download() has been deprecated. "&#xA;RuntimeError: imageio.ffmpeg.download() has been deprecated. Use &#x27;pip install imageio-ffmpeg&#x27; instead.&#x27;"&#xA;</module></module>

  



  would anyone please help to get out of this problem

  



  Here is the code:

  



  import cv2 
import os 
import time 
from moviepy.editor import VideoFileClip,concatenate_videoclips 
def vidcapt():
    a = time.strftime("%H,%M,%S")
    cap = cv2.VideoCapture(0)
    fourcc = cv2.VideoWriter_fourcc(*'XVID')
    out = cv2.VideoWriter(a+'.avi', fourcc, 24.0, (640,480))
    t1 = time.time()
    while(cap.isOpened()):
            ret, frame = cap.read() 
            if ret == True:
                    out.write(frame)
                    cv2.imshow('frame',frame)
                    t2 = time.time()
                    time_diff = t2-t1
                    if time_diff >= 5:
                            break
            else:
                    break
    cap.release()
    out.release()
    cv2.destroyAllWindows()

while True:
        vidcapt()


clip1 = VideoFileClip("11,05,42.avi")
clip2 = VideoFileClip("11,05,47.avi").subclip(50,60)
final_clip = concatenate_videoclips([clip1,clip2])
final_clip.write_videofile("merged.avi")


  


• Is there a way to stream download a mp3 file that is being converted on a nodejs server?

  19 February 2019, by Thriskel

  I am looking for a way to send the url to the nodejs server and respond the user with the mp3 file download.

  I searched some examples, and read about requests and responses, but I am not sure what the problem really is.

  This is the Javascript for the HTML:

      var downloadBtn = document.querySelector('.download_button');
  
      var URLinput = document.querySelector('#myUrl');
  
  
  
      downloadBtn.addEventListener('click', () => {
  
          console.log(`URL: ${URLinput.value}`);
  
          sendURL(URLinput.value);
  
      });
  
  
  
      function sendURL(URL) {
  
          window.location.href = `http://localhost:4000/download?URL=${URL}`;
  
      }

  This is the Javascript for the Nodejs server:

  const express = require('express');
  
  const cors = require('cors');
  
  const ytdl = require('ytdl-core');
  
  const app = express();
  
  const ffmpeg = require('fluent-ffmpeg')
  
  app.use(cors());
  
  
  
  app.listen(4000, () => {
  
      console.log('Server Works !!! At port 4000');
  
  });
  
  
  
  app.get('/download', (req,res) => {
  
  var URL = req.query.URL;
  
  
  
  res.header('Content-Disposition', 'attachment; filename="file.mp3"');
  
  let stream = ytdl(URL, { 
  
    quality: 'highestaudio',
  
  }); //HERE THE STREAM FILE IS SELECTED TO BE CONVERTED TO MP3
  
  
  
  ffmpeg(stream)
  
    .audioBitrate(128)
  
    .pipe(res); // HERE IS CONVERTED AND WHERE I WANT IT TO SEND IT AS A DOWNLOAD TO THE USER.
  
  });

  I expected it to stream download the file but instead it gets me to the nodejs server page to /download/url_to_vid

• How to download m3u8 to mkv in nodejs

  10 February 2019, by Gabgab2003

  Im trying to download an mkv file from an m3u8 stream. I have the m3u8 as url, but can download it to a file if need be. I would like to solve this only with node and node modules.

  I have already tried to use wget lib, but cant get ffmpeg (node library, not the standalone binary) to work with the file.

  if anyone is interested, the url im trying to download is this
  (Im writing a crunchyroll downloader application)
