  flac/metaflac : Limit the size of metadata blocks
  Limit allow image file size to slightly less than 2^24 bytes so that
  
  the file size plus extra house keeping data is strictly less that
  
  2^24 bytes in size.

• Unrecognized option from ffmpeg converting to html 5 video on upload

  19 avril 2015, par peterbw321

  I am gradually getting the hang of video conversion with ffmpeg but am stuck. I am on shared hosting. I can convert with simple code like -

  ffmpeg -i out.avi -acodec copy -vcodec copy output.mp4

  I need to convert to html5 video formats but whenever i use code like this, I always get the same type of error ’Unrecognized option c:v’ or ’Unrecognized option b’. Is my version of ffmpeg too old ? Please help.

  exec("/usr/bin/ffmpeg -i input -c:v libx264 -preset slow -crf 18 -vf yadif -strict -2 output.mp4");
