• Why can I run this command from the terminal but I get an error when my python runs it from the terminal for me ?

  9 mai 2019, par mu234

  I’m trying to write a python script that basically captures webcam videos from the terminal. When I put the command in a string and use subprocess.call(script, True), I get an error, but when I literally copy/paste the same command to the terminal it works fine.

  This is my python :

  import subprocess
  
  import os
  
  if (os.path.isdir("Videos/Webcam/temp") is False):
  
      dirmake = 'mkdir Videos/Webcam/temp'
  
      subprocess.call(dirmake, True)
  
  cmd = 'ffmpeg -f v4l2 -i /dev/video0 -t 00:00:10 video.webm'
  
  subprocess.call(cmd, True)

  and this is the error

  `FileNotFoundError: [Errno 2] No such file or directory: 'ffmpeg -f v4l2 -i /dev/video0 -t 00:00:10 video.webm': 'ffmpeg -f v4l2 -i /dev/video0 -t 00:00:10 video.webm'`

  If I just run ffmpeg -f v4l2 -i /dev/video0 -t 00:00:10 video.webm from the terminal it works fine.

  Originally the video was supposed to go in Videos/Webcam/temp but I took it out to see if the error had something to do with where I was putting the video. I’m using Ubuntu 18.04.2 LTS if that makes a difference.

• video hosting with PHP api or PHP script for social network project

  17 avril 2014, par al404IT

  I have a project for a small social network where user can upload their videos, video should not be longer than 1 or 2 minutes but they need to be private and related to user that uploaded.

  Since uploaded video may be in many different format I have two options :

  • upload video and use ffmpeg to process them, can i find any PHP script that does that ? PROS I have my files on my server and I'm not dependent from third party CONS I guess is a real intensive task and I may need a quite good noting plan since the beginning of this project

  • use a video hosting service that provide API to upload and process video, i actually find vzaar.com that may seems to do what I need. PROS Scalable CONS I rely on third party for my contents

  since the project is a small social network it may be interesting this too opusphp.com, but i never user or read about

  can Vimeo PRO suite my needs ? Other suggestions ?
  In future it may be necessary to add a basic video editing function to trim uploaded video setting starting and ending point
