• Laravel 7 Lumen, installing ffmpeg question

  30 mars 2021, par Gabriel Quezada Castro

  I'm trying to install FFMPEG from this git repository but my first question is :

  


  

  1. I don't have config/app.php on this project but git documentation refers to this .
Config/app.php

  


  


  I have these files inside app/config
This is what I have inside the project . My path MyProject/config/those files

  


  Finally, I get this error when I type the last code in the repository documentation :
php artisan vendor:publish —provider="ProtoneMedia\LaravelFFMpeg\Support\ServiceProvider"

  


  I get this error . What does It mean ? .

  


  Vendor error

  


  By the way, this is Git repository I'm trying to install . https://github.com/protonemedia/laravel-ffmpeg?fbclid=IwAR2bM2RXIcF4JtWg45_33vnIcMFp8YXdGqcndxmpHyQLnNAcWKUTtoefcik

  


  So, How Can I configure the project ? . Thanks for help me.

  


• Simple Question About Subprocess popen + screen +ffmpeg + youtube-dl

  2 juin 2021, par El_Barto_404

  ffmpeg -i "$(youtube-dl -x -g "https://youtu.be/xhXq9BNndhw")" -f s16le -ac 2 -ar 48000 -acodec pcm_s16le input.raw


  


  can anyone put this inside a popen process after a screen -S Convert ?

  


  I tried already with ' ', with commas.. but nothing

  


  I built a bot on telegram which if you send :

  


  .mandala youtubelink


  


  it takes the link and converts the video from YouTube into a uncompressed file, I need it for a music bot which streams those uncompressed files.

  


  if I run in console :

  


  ffmpeg -i "$(youtube-dl -x -g "https://youtu.be/xhXq9BNndhw")" -f s16le -ac 2 -ar 48000 -acodec pcm_s16le input.raw 


  


  it works but when I try with screen and popen it doesn't.. why ?

  


  @helper.register(pattern=r'.mandala (.+)')
async def mu2342sicbfffffffot(e):
    cheater = e.pattern_match.group(1)
    cheat = cheater
    myorder2224 = ''' "$(youtube-dl -x -g "{}")" '''
    doit = (myorder2224.format(cheater))

    ###  I already try to format the variable 
    ###  and put doit after -i and 
    ###  everything was in '' and commas 
    ###  like 'ffmpeg', 'i*, doit, '-f'...
    ###  and so on but nothing.. but nope doesn't work.

    p = subprocess.call(['screen','-S','onveter',' ffmpeg -i "$(youtube-dl -x -g "https://www.youtube.com/watch?v=Sw5HQbYGoCA")" -f s16le -ac 1 -acodec pcm_s16le -ar 96k  input.pcm'],shell=True)
  await helper.control_panel.send_message(config.chat, "La sto a manna")
  time.sleep(14)
  


  


  I REPEAT ONE MORE TIME :
HOW CAN I USE THAT FFMPEG COMMAND INSIDE A POPEN SUBPROCESS AFTER A Screen -S Convert ?

  


  IF SOMEONE WANT TO KNOW WHY :
Because I want to convert youTube videos to file .raw / .pcm

  


• FFmpeg Question : Proper Format to use when no transition is being used ?

  23 juin 2021, par HHH-Messenger

  I can NOT fine any examples so can someone point me in the right direction please.
I have many images with to short duration time to add transitions, and would like to know what the proper syntax and format is, for a text file ?
Would only the images with transitions be indexed, or all of them ?

  


  Also if my files are located in the directory C :\temp\ what does the text file look like below ?

  


  $ ffmpeg \
  
-loop 1 -t 1.4 -i 001.jpg \ (no fade in or out)
  
-loop 1 -t 1.65 -i 002.jpg \ (no fade in or out)
  
-loop 1 -t 1.9 -i 003.jpg \ (no fade in or out)
  
-loop 1 -t 2.6 -i 004.jpg \ (with fade out .500)
  
-loop 1 -t 2.35 -i 005.jpg \ (with fade in .500)
  
-loop 1 -t 1.4 -i 006.jpg \ (no fade in or out)

  Here is a common example : ALL IMAGES HAVE EFFECTS ADDED, PLEASE GIVE AN EXAMPLE WITH SOME HAVING EFFECTS AND SOME NOT HAVING EFFECTS ADDED.
