• Google AppEngine flex as a transcoder [closed]

  6 septembre 2021, par jACK

  Situation :

  


  

  • A Nodejs/Express application running on appengine flex.

  


  • Using FFmpeg to cut videos, and merge different types of videos. 1080p 30fps videos, merged video duration usually around 8 hours.

  


  • Need for a massive amout of processing power for those edits.

  


  • The express server needs to be reachable 24/7 & flex is incredibly expensive if run on a 24/7 basis.

  


  


  Goal :

  


  

  • To have a cost efficient ffmpeg transcoder on a private enviroment =>

  


  • Flex instance as a maximum spec, but as its idle reduce the price significantly.

  


  


  Or is this a situation where a redesign is imminent ? eg. Compute Engine

  


  Tried approach

  


  

  • B8 Standard instance => Since the payload is pretty big, its causing the B8 instance to crash.

  


  


  Thanks.

  


• Encoding videos locally or through a third party ?

  7 septembre 2015, par JordanDevelop

  We’re in the process on building a view uploading and sharing community right now and we’re currently developing with idea of using a third-party like Zencoder, but what makes Zencoder a better option ?

  I’m sorry if i butcher up what is involved with supporting a local encoding system, so I’ll try to be vague. We plan on releasing with AWS, so why not setup an instance running ffmpeg ? I understand it’s a lot more then simply that, but if is it that difficult to find someone who can put together an instance for encoding ?

  Am I right to assume most third party encoding services seem very unrealistic, price wise, for a web application who specifically focus on encoding large amounts of media ? I did notice Amazon offers an encoding features and would definitely feel more comfortable using them, but even that seems seems redundant.

  I completely understand the cost behind encoding is very real, but I just can’t understand why third-party encoders are so widely accepted.

• Can't run exec('ffmpeg') ; ffmpeg, wamp & windows 2008 server

  15 mars 2015, par Nicholas Walker

  i’ve installed FFMPEG on my windows server. If i go to cmd and type ffmpeg -version i get the version, available commands etc. I use WAMP server with php 5.4.12

  The reason i am not using ffmpeg-php is because i have installed it with no errors and i cant use the extension for php even tho it says it is installed.

  When i try to do

  <?php
  
  echo exec('ffmpeg -version'); 
  
  ?>

  its totally blank, no errors or nothing.

  If i run

  <?php
  
  echo exec('whoami'); 
  
  ?>

  i get : nt authority\system

  So i can run exec in my php.

  I’ve also tried the same with shell_exec() ; ffmpeg not working with either of them.

  After looking at other stackoverflow questions i’ve seen people fixing this problem by allowing IIS user to use ffmpeg.exe. But i am using Wamp so i don’t know what to do.

  Any ideas ?
