• Configuring ffmpeg as an rtmp server

  31 mai 2015, par Simon Dainty

  I’ve struggled for the past couple of days on this, without success, and I’d really like to get something working sooner than later - so I’d appreciate any feedback I can get.

  Anyway, I want to configure ffmpeg as an rtmp server that I can stream to (from anything that supports rtmp publishing - though, for experimentation, I’ll be using Open Broadcast Software). Right now I’ll just be happy to dump whatever is live streamed to a file, but in future I’ll be doing something more creative with it.

  So, with that in mind, could some kind soul please furnish me with an example commandline for ffmpeg that will accomodate me ?

  Thanks !

• twinvq : move all bitstream reading into single place

  twinvq : move all bitstream reading into single place
  This is required for the future addition of VoxWare MetaSound decoder, for its
  
  functions are mostly the same but bitstream reader is completely different
  
  and bitstream format is slightly different too.

• Redirect shell output for ruby script

  2 juin 2015, par rs41

  I have simple ruby script :

   #! /usr/bin/env ruby
  
   require 'fileutils'
  
  
  
   FileUtils.rm "output.mkv" if File.exists?("outp    ut.mkv")
  
   pid = Process.spawn("ffmpeg -i wrong_file.mp4 -c:v libx264 -preset veryslow -qp 0 output.mkv", STDOUT => "output.txt", STDERR => "error.txt")
  
  
  
   puts "pid : #{pid}"
  
   Process.wait(pid)

  But, STDOUT and STDERR outputs into error.txt, why ?

  It looks, that ffmpeg have another exit codes ?(in usual case 0 for stdout, and 1 for stdin)

  Note : I don’t want to use native shell redirect like ’> output.txt 2> error.txt’ because i want to get pid of ffmpeg process, not shell process and kill it in future.
