• 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 ?

  The pattern should match the entire value of the input, not just a subset.

• movenc : Add a flag for indicating a discontinuous fragment

  movenc : Add a flag for indicating a discontinuous fragment
  This allows creating a later mp4 fragment without sequentially
  
  writing the earlier ones before (when called from a segmenter).
  Normally when writing a fragmented mp4 file sequentially, the
  
  first timestamps of a fragment are adjusted to match the
  
  end of the previous fragment, to make sure the timestamp is the
  
  same, even if it is calculated as the sum of previous fragment
  
  durations. (And for the first packet in a file, the offset of
  
  the first packet is written using an edit list.)
  When writing an individual mp4 fragment discontinuously like this
  
  (with potentially writing the earlier fragments separately later),
  
  there’s a risk of getting a gap in the timeline if the duration
  
  field of the last packet in the previous fragment doesn’t match up
  
  with the start time of the next fragment.
  Using this requires setting -avoid_negative_ts make_non_negative
  
  (or -avoid_negative_ts 0).
