• cmdutils : Only do the windows-specific commandline parsing on _WIN32

  cmdutils : Only do the windows-specific commandline parsing on _WIN32
  Fixes commandline parsing on Cygwin (on 64 bit, and on very recent
  
  32 bit), where the configure check does find the CommandLineToArgvW
  
  function (since it exists in the link libraries and in the headers),
  
  but whose GetCommandLineW() only returns the application’s path.
  
  (This is due to a cygwin internal optimization, see
  
  http://cygwin.com/ml/cygwin/2013-07/msg00538.html for details.)
  
  Arguments are only given through main’s argc/argv, and they’re already
  
  UTF-8.

• ffmpeg live rtmp stream does not start to process for long time

  10 août 2013, par user1492502

  I have rtmp stream created by flash player in h264 but when i convert it to video or tumbnail using ffmpeg it some times works after very very long time and some time not work but if I create a stream with Flash Media live encoder on same FMS server the command below works fine. At the same time if I try the stream in player it works well and fine.

  I am using IP so DNS resolving issue is not possible either I think.

  ffmpeg -i rtmp ://xxx.xxx.xx.xx/live/bdeef2c065509361e78fa8cac90aac741cc5ee29 -r 1 -an -updatefirst 1 -y thumbnail.jpg

  Following is when it worked aftre 15 - 20 minutes 
  
  
  
  ffmpeg -i "rtmp://xxx.xxx.xx.xx/live/bdeef2c065509361e78fa8cac90aac741cc5ee29 live=1" -r 1 -an -updatefirst 1 -y thumb.jpg

  and on stopping the stream by closing the browser running the flash player which is publishing the video I get the following

  when if i stop the stream it quickly creates a thumbnail file where as running stream is an issue.
