• php ffmpeg cannot save video to system temporary folder

  28 mai 2024, par user2818066

  I am trying to covert a video to h.264 format. I can save the new video to a normal directory but saving the new video to a Windows temp file fails. However I can manage to save a snapshot image from the video into Windows temp folder without problem. I cannot figure out what is the problem ?

  


  require_once(dirname(__FILE__).'/../vendor/autoload.php');

function get_ffmpeg_exe_path_arr_def(){ 
  return( array( 'ffmpeg.binaries'  => "C:/bin/ffmpeg.exe",
                 'ffprobe.binaries' => "C:/bin/ffmpeg.exe",
                 'timeout' => 3600000000, 'ffmpeg.threads' => 12
                )   )  ;  
}

$vid_inp = 'C:/Users/Jordan/Downloads/motorboat_org.mp4' ; 
$vid_out = 'C:/Users/Jordan/Downloads/motorboat_9.mp4' ;
$tmp_vid_out_file = tempnam(sys_get_temp_dir(), "Vid") ; //C:\Windows\Temp\VidA318.tmp 
$tmp_img_file = tempnam(sys_get_temp_dir(), "Img") ; //C:\Windows\Temp\ImgA234.tmp


$ffmpeg = FFMpeg\FFMpeg::create( get_ffmpeg_exe_path_arr_def() );
$video = $ffmpeg->open($vid_inp);
$format = new FFMpeg\Format\Video\X264('aac', 'libx264');

$video->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(0.2))->save($tmp_img_file);
// Ok to save snapshot image to  C:\Windows\Temp\ImgA234.tmp 

$video->save($format, $vid_out); 
// This is ok to save video to  C:/Users/Jordan/Downloads/motorboat_9.mp4

$video->save($format, $tmp_vid_out_file); 
// This fails to save new video to   C:\Windows\Temp\VidA318.tmp

• checkasm : Properly save rdx/edx in checkasm_call() on x86

  16 août 2015, par Henrik Gramner

  checkasm : Properly save rdx/edx in checkasm_call() on x86
  If the return value doesn’t fit in a single register rdx/edx can in some
  
  cases be used in addition to rax/eax.
  Doesn’t affect any of the existing checkasm tests but it’s more correct
  
  behavior and it might be useful in the future.

• Can we set size of image frame in save function ?

  19 avril 2019, par Tester

  Unable to set the size of image frame so I am unable to use thumbnail size.

  $video = $ffmpeg->open($videoFile);
  
  $video
  
      ->filters()
  
      ->resize(new FFMpeg\Coordinate\Dimension(320, 240))
  
      ->synchronize();
  
  $frame = $video->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(1));
  
  $frame->save('C:\wamp64\www\woc\image_bucket\thumbnail\\'.$thumbnailFileName);
