• -vf unrecognized with php exec() function

  29 septembre 2011, par Rajat

  I am using php to create a video with fade effects. But exec() function gives following output :

  Why it is giving unrecognized option 'vf' while it works fine when run directly on server.My command is : "ffmpeg -i /usr/slideshow/frame1.mp4 -vf 'fade=out:0:5' /usr/slideshow/fade1.mp4"

  I am executing it with exec() function. Why the error is coming and what should i use to apply filter to my input video. I am working on CentOS server.

  Please guide me...

• Unknown OS 'msys_nt-6.1'. using Minw on win7 64bit

  31 mai 2015, par user63898

  i try to compile FFmpeg from source using MSYS2 and MIngW im using win7 64 bit .
  using .

  $ ./configure --enable-shared

  im getting this error :

  Unknown OS 'msys_nt-6.1'.
  
  
  
  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
  
  solve the problem.

  looking in to config.log
  i see ( the end of the log ) :

  gcc -std=c99 -Wall -O3 -c -o /tmp/ffconf.fnJeLuIu.o /tmp/ffconf.e8DJYGJM.c

• Unrecognized option 'c:v' ffmpeg error for converting videos to H264

  16 mai 2015, par user3528346

  I told my server to upgrade to latest version of ffmpeg and they told me they did and I have the latest version that is 2.2.1 .
  I test several codes to convert a video to x264 , here is the one ;

  passthru("$ffmpegpath -i aatest/a.AVI -c:v libx264 -c:a libfaac -preset veryslow -qp 0 aatest/output.mp4 2>&1");

  What should I do ?
