• How to create a JavaScript code to convert a YouTube video to mp3 on a website ?

  2 octobre 2019, par Uyen_77

  How does one take a YouTube link and convert it to mp3 ? I’ve seen this done on a few sites like : https://y2mate.com/ and https://ytmp3.cc/

  How is code like this written ? I want to do this in JavaScript but not sure how to implement. The way I am trying to make the site is by writing the code like :

  1. Load with curl : https://youtube.com/Watch
  2. Parse json & extract url
  3. Download video to server
  4. Use ffmpeg to convert
  5. Send url to user
  6. Allow them to download the extracted audio

  Can someone show what the code for this would look like.

  If anyone knows of a better way to do this for a website please explain.

  Thank you

• Live TV Stream to Android

  8 mai 2016, par Hd Dream

  I am new user on stackoverflow.
  I wrote you today to get answer and solution to my problem.
  I have input stream come from vlc. I need that all android connected to my network can watch stream in live in the same time like an online channel tv.
  I saw for this channel

  Code : Select all
  www.canal2international.net/live.php

  there is a same ts file is generated for each 45 second.

  I need to do the same but with a mp4 file that I insered on html5 video tag.
  for that I tried to convert my input stream with this cmd on ffmpeg

  Code : Select all
  ffmpeg -i 192.168.1.10:8620 -c:v libx264 -profile:v baseline -c:a aac -ar 44100 -ac 2 -b:a 128k -f segment -segment_time 45 -segment_format_options movflags=+faststart -segment_list D :\live\play.m3u8 -segment_list_size 2 D :\live\watch%03d.mp4

  I’m not satisfied. I can’t insert m3u8 file in html5 video tag because android don’t read it and his content.

  I tried another code that I can say little similar that the result of this page

  Code : Select all
  www.canal2international.net/live.php

  Code : Select all
  ffmpeg -i 192.168.1.10:8620 -hls_flags single_file D :\live\play.m3u8

  It generated two files, a ts and a m3u8.
  I know that html5 video tag can read ts file. Maybe there is a solution somewhere.

  The second way I don’t like in this code is ts file don’t read in real time. When I read file it begin from the first encoding.

  All android connected to my network must watch in real time !

  I don’t know how to solve my problem that’s why I write in thie forum.

  Thank you in advance for all your help !

• How can I make smooth zooming video from image sequence in FFMPEG ?

  26 octobre 2020, par CALKing

  I need to make a video from an image sequence, actually a deepdream image sequence I have generated. And I've generated the images so that every image is a 1.05 x zoom on the last image, hoping to be able to make something like this : https://www.youtube.com/watch?v=dbQh1I_uvjo. But because of the demanding CPU deepdreaming requires, I didn't have the time and resources to generate images for a 30 fps video, but more like a 1 fps video. Which I actually managed to do, my code for that looks like this :

  


  ffmpeg -r 1 -i %04d.jpg -c:v libx264 -r 10 output.mp4


  


  Now to make the video smoother I want to smoothly zoom in 1.05 x on every image in the sequence for about a second or two before continuing to the next image, which should then be in position with the one before. I have no experiene at all with FFMPEG and can't find much help on the internet. Could anyone help me with this ?

  


  Thanks !
