• FFMPEG - Stream discovered after head already parsed [on hold]

  7 février 2014, par John Doe

  I am trying to live transcode an RTMP stream to another RTMP HLS stream using the following command :

  ffmpeg -re -i rtmp://localhost/videochat/testing -c:v libx264 -c:a:0 libfaac -b:a:0 480k -f flv rtmp://localhost:12345/hls/mystream;

  However I receive the following error and the transcoding never begins :

  Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 (rtmp://localhost:12345/hls/mystream) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
  
  Output #0, flv, to 'rtmp://localhost:12345/hls/mystream':

  If anyone has ever dealt/solved this problem before, can you please share as I have been trying to solve this for 2 days but to no avail !

• 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 ?
