• Is there any way to trim YouTube video without downloading it to local machine ?

  12 août 2020, par Sonu Bamniya

  I am creating an app to trim video where a user either can upload the video file or can paste YouTube URL.
I am able to make the trimmer work for upload video using FFmpeg, but for YouTube URL, firstly I need to download the video to the local machine and then trim it using FFmpeg.

  



  I am using youtube-dl NodeJS library to save the video file to locally, but the issue is as I am allowing the user to download only 15Sec video no more than that, and I have applied validation of 60m long video, yet when I get 1080p video there are two issues.

  



  1. There is no audio in the 1080p video.


  



  and

  



  2. The video is taking too long to download locally and the process is taking almost 7-8mins to complete.


  



  For the first one, I can get the audio and video separately and then merge both of them in the video, but the second one is where I am stacked.

  



  I have added a time log I can see the trimming is taking only about 3-4 seconds, but the downloading is taking too long.

  



  Is there any way to make it work faster ? Or, Is there any way I can download only that part of the video, not the full video, in any technology.

  



  I am open to using any technology until it is working faster than my current implementation.

  



  If this is something related to server configuration, please suggest which one would work better.

  21 novembre 2019, par Wasp Nesser

  I have got a python code for downloading a video (from youtube) and converting to mp3. I used youtube-dl for these. Python code works in computer. But that error occurred in my android :

  youtube_dl.utils.DownloadError: ERROR: ffprobe/avprobe and ffmpeg/avconv not found. Please install one. [Program finished]

  I couldn’t find how to install these requirments in android . I use application called pydroid3 for executing python codes , installing python libraries and terminal staff. I tried to install ffmpeg and ffprob libraries with pip .But it didn’t helped me. After I tried to execute

  adb shell pm install ffmpeg 

  And It didn’t helped me to.

  This is my code :

  import youtube_dl
  
  import os 
  
  outtmpl = "%(playlist_title)s-%(playlist_uploader)s /%(playlist_index)s %(title)s-%(uploader)s.%(ext)s"
  
  ydl_opts = {
  
      'format': 'bestaudio/best',
  
      'postprocessors': [{
  
          'key': 'FFmpegExtractAudio',
  
          'preferredcodec': 'mp3',
  
          'preferredquality': '192',
  
      },
  
          {'key': 'FFmpegMetadata'},
  
      ],
  
      'outtmpl' : outtmpl,
