• how to convert video file via ffmpeg in php ?

  4 janvier 2015, par ali raha

  In SSH centos terminal, I run it via this command :

  $HOME/bin/ffmpeg -i test.mp4 test.webm

  I tried this

   $ffmpegPath = "/home/bin/ffmpeg";
  
    //or $ffmpegPath = "/bin/ffmpeg";
  
  
  
  
  
  
  
  
  
    $outPath=$outPath."/".$newname.$format;
  
    shell_exec("$ffmpegPath  -i $inputPath $outPath");

• How to compile ffmpeg via Alchemy gcc ?

  3 juillet 2014, par Rella

  So I created ffmpeg configuration file that makes it pure C (platform independent, but only theoretically)

  So my config is simple (0.6.1,0.6.3 tested) :

  ./configure  --disable-doc  --disable-ffplay --disable-ffprobe  --disable-ffserver    --disable-avdevice   --disable-avfilter   --disable-pthreads  --disable-everything --enable-muxer=flv --enable-encoder=flv --enable-encoder=h263  --disable-mmx  --disable-shared   --prefix=bin/  --disable-protocols --disable-network --disable-optimizations --disable-debug  --disable-asm --disable-stripping

  Compiling this on Linux will resolve in 4 libs with totall size of 1 mb.

  But I need to compile ffmpeg with custom compiler (opensource gcc analog called Adobe Alchemy, lets us compile C/c++ into Flash)

  It gives me errors on nearly each and every file during standart Make :

  Array @ARGV missing the @ in argument 1 of shift() at /home/rupert/Downloads/alchemy-ubuntu-v0.5a/achacks/gcc line 218.
  
  cc1: error: unrecognized command line option "-Wtype-limits"
  
  cc1: error: unrecognized command line option "-fno-signed-zeros"

  So what shall I do - how to compile ffmpeg (at least smallest part of it) via alchemy ?

  Update
  If we would fix that errors manually (2 in configure.mak and one in alchemy gcc) we would get a really messy and long output like :

  > $ make -w install
