• FFMPEG Python command too long

  22 janvier 2024, par billy 356

  I am trying to make a program that will overlay some images with a "slide" animation.
So I am doing this with FFMPEG in my Python code, and there are lots of files and commmands since the slide animation is frame per frame.

  


  for i in range(1, fps): h = yscale - ratio * (fps-i) # print(h) bg = bg.overlay(img_split[i].filter('crop', w1*scale, h, 0, 0), enable=f"between=(t, {nt},{nt + tsp})", x=x, y=y) nt += tsp

  


  this is where I am overlaying the images, and this is where i export the "bg"

  


  ffmpeg.output(bg, path, vcodec='h264_nvenc', **{'b:v': '30M'}).run(overwrite_output=True)  

  


  But since there are lots of small changes, the FFMPEG command is very long, so I get the following error :
FileNotFoundError: [WinError 206] The filename or extension is too long

  


  I tried to get the command and execute it separetly.
With FFMPEG you can get the command by doing ffmpeg.output(...).get_args(), which gives a list of arguments
I tried putting these in a file and run the file with batch but I had this error
C:\Users\billy\Desktop\tests\MIXER>bash cmd.txt cmd.txt: line 1: syntax error near unexpected token t,'
cmd.txt : line 1 : ffmpeg -i project/_pk.mp4 -i project/images/1.png -i project/images/2.png -i project/images/3.png -i project/images/4.png -i project/images/5.png -i project/images/6.png -i project/images/7.png -i project/images/8.png -i project/images/9.png -i project/images/10.png -i project/images/11.png -i project/images/12.png -i project/images/13.png -i project/images/14.png -i project/images/15.png -i project/images/16.p (I didn't copy the whole thing as it's very long)

  


• Taking too long to generate a ScreenShot in ffmpeg

  29 novembre 2018, par Vishnu

  I am generating a Screenshot by using ffmpeg. Its generating the thumbnail but its taking too long (more than 2 minutes).

  I have referred this link

  create thumbnails from big movies with FFmpeg takes too long

  But I have to set in my nodejs code

  ffmpeg(main_folder_path)
  
    .on('filenames', function(filenames) {
  
      console.log('Will generate ' + filenames.join(', '))
  
    })
  
    .on('end', function() {
  
      console.log('Screenshots taken');
  
    })
  
    .screenshots({
  
  pro_root_path+'public/uploads/inspection/'+req.body.clientID+'/images/'
  
  timestamps: [30.5, '20%', '01:10.123'],
  
  filename: 'thumbnail-at-%s-seconds.png',
  
  folder: pro_root_path+'public/uploads/inspection/'+req.body.clientID+'/images/',
  
  size: '320x240'
  
    });

  I used timestamp But even though its taking more than 2 minutes. How do I fix this Issue.
