• 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");

• The type or namespace name 'ImageEntitiesContainer' could not be found

  10 avril 2015, par KeithJ

  I’m trying to build a C#.NET application from the source code of a solution provided here.

  I’ve already added a reference to AForge.Video.FFMPEG.dll, but I am still getting the following error :

  Error 2 The type or namespace name ’ImageEntitiesContainer’ could not
  be found (are you missing a using directive or an assembly
  reference ?) C :\WorkSpace\Visual Studio
  2013\Projects\CSharp\ImagesToVideo\Program.cs 56 40 ImagesToVideo

  I searched for this error and found a few posts, but nothing that helps. I tried changing the target framework from my default ".NET Framework 4.5" to some other frameworks : ".NET Framework 2.0", ".NET Framework 3.0", ".NET Framework 4.0", but without any success. Does anyone have any idea why I am still getting this error ?
