• Trying to compile x264 and ffmpeg for iPhone - "missing required architecture arm in file"

  11 février 2013, par jtrim

  I'm trying to compile x264 for use in an iPhone application. I see there are instructions on how to compile ffmpeg for use on the platform here : http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2009-October/076618.html , but I can't seem to find anything this complete for compiling x264 on the iPhone. I've found this source tree : http://gitorious.org/x264-arm that seems to have support for the ARM platform.

  Here is my config line :

  ./configure —cross-prefix=/usr/bin/ —host=arm-apple-darwin10 —extra-cflags="-B /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/lib/ -I /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/lib/"
  

  ...and inside configure I'm using the gas-preprocessor script (first link above) as my assembler :

  gas-preprocessor.pl gcc
  

  When I start compiling, it chunks away for a little while, then it spits out these warnings and a huge list of undefined symbols :

  ld : warning : option -s is obsolete and being ignored
  ld : warning : -force_cpusubtype_ALL will become unsupported for ARM architectures
  ld : warning : in /usr/lib/crt1.o, missing required architecture arm in file
  ld : warning : in /usr/X11R6/lib/libX11.dylib, missing required architecture arm in file
  ld : warning : in /usr/lib/libm.dylib, missing required architecture arm in file
  ld : warning : in /usr/lib/libpthread.dylib, missing required architecture arm in file
  ld : warning : in /usr/lib/libgcc_s.1.dylib, missing required architecture arm in file
  ld : warning : in /usr/lib/libSystem.dylib, missing required architecture arm in file
  Undefined symbols :
  

  My guess would be that the problem has to do with the "missing required architecture arm in file" warning...any ideas ?

• Echoprint-codegen perpetual "error" :"could not decode" from shell_exec

  16 janvier 2016, par sid405

  I am trying to run codegen from popen (shell_exec creates the same scenario) in php in my Mac lion MAMP box as follows :

  $handle = popen('echoprint-codegen "/Applications/MAMP/htdocs/projectx/codegen/2.mp3" 10 30', 'r')
  
  
  
  echo "'$handle'; " . gettype($handle) . "\n";
  
  $read = fread($handle, 2096);
  
  echo $read;
  
  pclose($handle);

  But i am perpetually met with

  "error":"could not decode", "tag":0, "metadata":{"filename":"/Applications/MAMP/htdocs/projectx/codegen/2.mp3"}}

  No matter how i format the cmd inside the handle, with various variations of single and dbl quotes i still get the same thing.

  codegen is in the path and so is ffmpeg.

  Here’s the kicker. Codegen works fine from command line and so does the php script with the popen() or the shell_exec().

  From browser it won’t work.

  Any ideas ?

  Thank you in advance
