• ffmpeg convert images to mp4 error

  31 mai 2013, par Ryan Saxe

  So I have a script that grabs a bunch of images from the web and then converts them into a movie. Yet I get a whole bunch of errors when I run it.

  First let me show what I am running and then I will post the error because it's huge :

  #for gif
  
  #call('convert -set delay 5 -loop 0 ' + folder + '*.jpg ' + name + '.gif', shell=True)
  
  #for mov
  
  #call('convert -quality 100 ' + folder + '*.jpg ' + name + '.mov', shell=True)
  
  #for organized movie
  
  call('ffmpeg -r 10 -b 1800 -i ' + folder + '%0' + str(size) + 'd.jpg ' + name + '.mp4', shell=True)

  So the commented out versions work fine, but I need to use the 3rd version ! Here is the response I get from ffmpeg :

  repeated about 30 times, but i cut it out of the traceback because it was overwhelming.

  Question : What did I do wrong and how do I fix it ?

  Edit :

  I download the jpeg files using the urllib python library's urlretrieve. This is how I save them :

  for src,name in zip(urls,range(len(urls))):
  
      file_name = folder + str(name) + '.jpg'
  
      urlretrieve(src, file_name)

• Error in FFMpeg and png images (glob/libavformat) [closed]

  1er juin 2013, par Alain P. Francés

  I'm trying to use FFMpeg to produce an animation based on several png images
  that don't follow a sequence number. With
  the following command line

  ffmpeg -f image2 -r 1 -pattern_type glob -i '*.png' -c:v libx264 mov.mp4

  I obtain the following error

  25 septembre 2013, par user2767347

  I want to convert a mov video into mp4 using ffmpef library of php.
  I am using given code :

  $cmd='ffmpeg -i sample.mov -sameq output.mp4';
  
  echo exec($cmd);

  It is not working at all. Even I didn't get any error. Could anyone tell me the proper steps to do this conversion. I have tried a lot of code examples but not working for me.
