  bfin : dsputil : Drop broken vsad bits
  They were marked as broken and disabled in 2009 and will never get fixed.

  libFLAC/cpu.c : Simplify OS SSE support detection.
  Simplify the code that tries to detect whether OS supports SSE instructions.
  a) Linux : "old" vs "new" sigaction
  OBSOLETE_SIGCONTEXT_FLAVOR was disabled in Mar 2007 in commit 1ca3a445f.
  
  According to <http://unixhelp.ed.ac.uk/CGI/man-cgi?sigaction>: "Support for
  
  SA_SIGINFO was added in Linux 2.2" (released in Jan 1999). If noone wants to
  
  use FLAC with Linux kernel 2.0 then it’s safe to delete this code.
  b) MSVC : try/catch vs. sigill_handler
  TRY_CATCH_FLAVOR was enabled in Jan 2009 in commit a832ef32. According to the
  
  comment in cpu.c, "sigill_handler flavor resulted in several crash reports on
  
  win32". Also this sigill_handler flavor is not thread-safe.
  c) MinGW : fxsave/fxrestore vs. sigill_handler
  The code was added Mar 2014 in commit 99d5154f. It’s better to use FXSR flavor
  
  instead of sigill_handler flavor. The reasons are the same as for MSVC.

• ffmpeg output + issues

  3 octobre 2014, par Ford

  I am trying to get ffmpeg to work using PHP, in its most basic format, just as a test before i develop my code further.

  However i can not get it to work and get no error messages or indications to what is wrong :-(

  i am trying :

  echo exec("/usr/bin/ffmpeg -y -i /home/xxxxxx/public_html/videos/1746/0765916.avi /home/xxxxxx/public_html/videos/1746/test.mp4"); 

  this is creating a 0kb file, but nothing else :-(
  i get no error message (or anything else !)

  (i have error_reporting turned ON and nothing is displayed in browser or server logs)

  if i add the below to get the codecs available :

  echo exec("ffmpeg -formats");

  this just outputs "worse."

  I do not have access to command line, as i am using a shared hosting server.

  I have had the host run the above from command line, and they say it says "codec not found" or words to the effect.

  is there any way i can get any error output into my php file so i can see what is happening.

  Also how do i go about installing codecs, if this is the problem (the host will install them, but have mentioned they have never installed a codec on a Linux box, so would be grateful if i could point them to any install info too)

  Thanks in advance !

  EDIT :

  after adding in the code that @stewe suggests, this is the output when trying to convert to mp4

  (i can convert to to other formats fine )

  If anyone can help as to how to fix this issue, as i would ideally like to convert to mp4
