• PHP-FFMPEG Waveform is a little noisy, how to fix that ?

  18 avril 2023, par Kranchi

  I made a waveform through sample code :

  


  $waveform = $audio->waveform(2000, 500, array('#FFA500'));
$waveform->save('waveform.png');


  


  But result has some noise in top & bottom of edges :
https://gcdnb.pbrd.co/images/80v6Up6etCrD.png?o=1

  


  So I made a tiny change in line 140 of src\FFMpeg\Media\Waveform.php :

  


  //'showwavespic=colors='.$this->compileColors().':s='.$this->width.'x'.$this->height,
'showwavespic=draw=full:colors='.$this->compileColors().':s='.$this->width.'x'.$this->height,


  


  And problem fixed :
https://gcdnb.pbrd.co/images/KsCFsOujmJ9W.png?o=1

  


  I'm not sure is this a bug or problem in FFMpeg dll file and my question :

  


  is it possible to send the new command or override save method to avoid hacking the original file ? (the save method is using some protected methods)

  Thanks.

• ffmpeg works at command line but I got this error when I use it in nodejs app :

• ffmpeg conversion failed error while splitting a 1.57GB .tif file

  12 janvier 2023, par Minai

  I am running ffmpeg to split a large .tif image of dimensions 25966 * 64114 into grids 0f 256 * 256 pixels but am getting an error.

  


  I ran the ffmpeg command on an 1883 * 1361 pixel .jpg image named coral2

  


  Here is the image

  


  Using the following command :

  


  ffmpeg -i coral2.jpg -qscale:v 1 -vf "crop=256:256:0:256" coral2-0-256.jpg

  


  Here is the crop

  


  When I run the same command on a 1.57GB .tif image :

  


  image.tif -qscale:v 1 -vf "crop=256:256:0:256" image%01d.tif

  


  I get the following error :

  


  


  


  C :\Users\gwmin\Downloads\coral\southbayapal>ffmpeg -i image.tif -qscale:v 1 -vf "crop=256:256:0:256" image%01d.tif
