  TypeError: must be real number, not NoneType.


  


  It used was to run but I don't remember if I might have updated numpy, ffmpeg, or any thing else that is now causing the error. I have tried the code on python 3.10 and 3.11 and get the same error in both. I was previously running it on python 3.10.

• get metadata and download mp4 video link to server with ffmpeg

  17 mars 2019, par user892134

  I have the following directory in server /home/example.com/videos

  I want to download this video http://example.com/videos/video.mp4 into the directory.

  First how do i get metadata of http://example2.com/videos/video.mp4 ?

  Here is my command to download video, is it correct ?

  ffmpeg -i "http://example2.com/videos/video.mp4" -c copy "/home/example.com/videos/video2.mp4"

  Lastly, how do i determine if video has downloaded or didn’t finish downloading successfully ?

• Using ffmpeg with MAMP local server

  22 mai 2012, par dirk_22

  In my MAMP local server home folder on Mac OS X (htdocs), I have a bunch of images (labeled image0 through image(n)) which I would like to stitch together into a jpeg using ffmpeg. When I type the following command into terminal, a .mpg file is successfully generated.

  ffmpeg -f image2 -i image%d.jpg videofile.mpg

  However, when I try to execute the same command using the php code pasted below, nothing seems to happen.

  <?php
  
  shell_exec('ffmpeg -f image2 -i image%d.jpg videofile.mpg');
  
  ?>

  I've copied the installed ffmpeg folder on my home directory into htdocs, but ffmpeg doesn't seem to be accessed. I'm very new to PHP, so please feel free to point out any gross errors in my code. I'd just like the php script to accomplish the same task which terminal executes upon input of the aforementioned command. I'd welcome any and all advice. Cheers.
