  Work on a copy of the headers in _initXHRData
  If someone passes a "headers" options to fileupload(), this object get overwritten across multiple files upload because the same object is being re-used.
  

• How to pass options to ffmpeg from SoX ?

  8 octobre 2012, par beardedlinuxgeek

  I'm trying to combine and encode some files from wav to m4a. I installed both ffmpeg and sox from source to make sure nothing was disabled. When I do the conversion with ffmpeg

  ffmpeg -i input.wav -acodec aac -strict experimental output.m4a

  it works fine. When I use SoX

  sox input.wav output.m4a

  I get the error

  [NULL @ 0x251b4e0] Codec is experimental but experimental codecs are not enabled, see -strict -2
  
  sox FAIL ffmpeg: ffmpeg could not open CODEC
  
  sox FAIL formats: can't open output file `output.m4a':

  I need to way to get SoX to tell ffmpeg that its ok to use the experimental codecs.

  Also I already tried using this guide http://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide to install the fdk-acc encoder, but it didn't work. The experimental one works fine so I'd rather just use that.

• Live streaming doesnt work

  13 février 2013, par John Smith

  Im using FFmpeg to capture my screen :

  ffmpeg -f dshow -i video="UScreenCapture" -r 5 -s 640x480 -acodec libmp3lame -ac 1 -vcodec mpeg 4 -vtag divx -q 10 -f mpegts tcp://127.0.0.1:1234

  so let it stream to somewhere. The accepter script :

   error_reporting(E_ALL); /* Allow the script to hang around waiting for connections. */
  
   set_time_limit(30); /* Turn on implicit output flushing so we see what we're getting as it comes in. */
  
   ob_implicit_flush();
  
  
  
  
  
  $address = '127.0.0.1';
  
  $port = 1234;
  
  $outfile = dirname(__FILE__)."/output.flv";
  
  $ofp = fopen($outfile, 'wb');
  
  
  
   if (($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) === false) { echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n"; sleep (5); die; }
  
   if (socket_bind($sock, $address, $port) === false) { echo "socket_bind() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n"; sleep (5); die; }
  
   if (socket_listen($sock, 5) === false) { echo "socket_listen() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n"; sleep (5); die; }
  
   if (($msgsock = socket_accept($sock)) === false) { echo "socket_accept() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n"; sleep (5); break; }
  
   do {
  
      $a = '';
  
      socket_recv ($msgsock, $a, 65536, MSG_WAITALL);
  
      fwrite ($ofp, $a);
  
      //echo strlen($a)."\r\n";
  
   } while (true);

  it seems to save the stuff to the disk OK. Now here comes the html :

  I dont really know how to do this, but based on an example :

  <video src="/output.flv"></video>

  but it doesnt do anything. And if I want to stream the live incoming stuff, then whats the matter ?
