• nodejs FFMPEG add multiple inputs not working

  23 octobre 2019, par HUNG

  var ffmpeg = require('fluent-ffmpeg');
  
  var proc = 
  
  ffmpeg()
  
  .input('./_animation/overlay1_%04d.png')
  
  .inputFPS(20)
  
  .input('./_animation/overlay2_%04d.png')
  
  .inputFPS(20)
  
  .input('./_animation/static1.png').inputFPS(1)
  
  .input('./_animation/static2.png').inputFPS(1)
  
  .outputFPS(20)
  
  .save('./public/_ugc/' + new Date() + '.mp4');

  I would like to create a video which combining from 4 sources, i.e. overlay1 sequences, overlay2 sequences and two static images. However, it is now always shows only one of the sources only. How to combine them in each of the frame ?

  And since the sources are not in the same dimension, is it possible to set the x,y coordinate for the sources ?

• FFmpeg On iOS can’t find delogo

  8 mai 2018, par Y.Y.Doe

  I integrated FFmpeg on iOS，and use “delogo” to clean watermark，but it does not work.
  And it logs :

  No such filter:delogo

  I don’t know why,and I need help

  it’s my iOS code to use FFmpeg

  dispatch_async(dispatch_get_global_queue(0, 0), ^{
  
      char *outPic = (char *)[DocumentPath(@"delogo.mp4") UTF8String];
  
      char *movie = (char *)[BundlePath(@"logo.mp4") UTF8String];
  
      char *a[] = {
  
          "ffmpeg",
  
          "-i",
  
          movie,
  
          "-vf",
  
          "delogo=x=10:y=10:w=250:h=120:show=1",
  
          outPic
  
      };
  
      ffmpeg_main(sizeof(a)/sizeof(*a),a);
  
  });

• Converting and Compressing a Video with FFmpeg

  29 avril 2019, par Supercoder54551

  I’m using FFmpeg to convert and compress a video. Everything converts/compresses fine, but my video has no sound when I try to play it on a mobile device. But it has sound when I play it on a desktop. I don’t know if this has to do with the codec that I am using, I don’t know. Can someone help me ? I appreciate it. Thank you.

  The format that I am using in FFmpeg :

  $request->video->move(public_path('/app'), $filename);
  
          $name_file=uniqid().'intro_video.mp4';
  
       $ffp=FFMpeg::open($filename)
  
  ->addFilter(function ($filters) {
  
      $filters->resize(new \FFMpeg\Coordinate\Dimension(640, 480));
  
  })
  
  ->export()
  
  ->toDisk('s3')
  
  ->inFormat(new \FFMpeg\Format\Audio\Aac)
  
  ->save($name_file);
