• Compiling ffmpeg for iOS and gas-preprocessor.pl

  16 mai 2017, par user500

  I want to compile ffmpeg for iOS. I did it a few times before. But now I’m on clean new Mavericks and on configure I’m always getting

  Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
  
  Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
  
  GNU assembler not found, install gas-preprocessor
  
  
  
  If you think configure made a mistake, make sure you are using the latest
  
  version from Git.  If the latest version fails, report the problem to the
  
  ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
  
  Include the log file "config.log" produced by configure as this will help
  
  solving the problem.

  I have current Xcode installed. Also brews. And current gas-preprocessor.pl (https://github.com/yuvi/gas-preprocessor) in usr/bin and also in usr/local/bin.

  On perl /usr/bin/gas-preprocessor.pl gcc I’m getting Unrecognized input filetype at /usr/bin/gas-preprocessor.pl line 33.

  This config works :

  This code use for live streaming for send data using RTMP Wrapper.
  Not write in Socket properly because every 5 second to generate different file output file.

  This is proper way ?

  I have no idea how to get NSData in proper way.

  Please help me .
