• iPhone recorded videos getting rotated on Windows systems [migrated]

  11 mars 2013, par Saurabh

  I am recording videos on iPhone and uploading them to my Linux server. Users can see these videos on website. If users are seeing videos on mac or iDevices the video is looking fine but when users are seeing that video on windows systems these videos are getting rotated.

  I am assuming this is because of some apple's flag in the recorded video which Windows systems are not able to read. Can I record videos in some way so they don't get rotated on Windows systems ? Or is there any way I can re-encode videos with proper interface orientation using FFmpeg ?

  I am open to both FFmpeg or iOS way.

  PHPVideoToolkit Error: Execute error. Output for file "C:\xampp\htdocs\phpvideo\examples\working\tmp\1336156630-4fa421d69357d\tmp_%d.jpg" was not found. Please check server write permissions and/or available codecs compiled with FFmpeg. You can check the encode decode availability by inspecting the output array from PHPVideoToolkit::getFFmpegInfo().

  i m trying to make it work since last many hours but no luck

  Also, for this code :

  $srcFile = "test-mpeg.mpg";
  
  $ffmpegObj = new ffmpeg_movie($srcFile);

  i am gettign error that it cant file the file. i believe its something to do with permissions but i m not able to figure out

  fpoen , fwrite , file_put_contents all are working fine without any permissions problems.

  can anyone please guide me in the write direction. what do i need to do to make this phpvideotoolkit work

• FFMPEG : preset not found in Windows Vista

  12 juin 2012, par StackOverflowNewbie

  I download FFMPEG from http://www.videohelp.com/tools/ffmpeg#download and saved it in my c :\program files\ffmpeg (Windows Vista). My Path's first 2 entries are :

  c:\program files\ffmpeg\bin;c:\program files\ffmpeg\presets;

  I found the following command on the net (http://paulrouget.com/e/converttohtml5video/)

  ffmpeg -i input.avi -acodec libvorbis -ab 96k -vcodec libx264 -vpre main -level 21 -refs 2 -b 345k -bt 345k -threads 0 -s 320x240 output.mp4

  When I run this on command line, I get the following error :

  File for preset main not found

  Any ideas what might be wrong ?
