• php - how to make thumbnail of video with out ffmpeg

  9 septembre 2018, par engineer emir

  I’m using php ( Phalcon frameWork ) .

  I tried to using ffmpeg to do this but its taking too much .

  I need a thumbnail as screen shot from video .

  Is there any other solutions ( Only PHP ) ?

  this is my code :

      // where ffmpeg is located, such as /usr/sbin/ffmpeg
  
      $ffmpeg = '/usr/bin/ffmpeg';
  
  
  
      // the input video file
  
      $video  = BASE_PATH . "/public/uploads/video/" . $fileName;
  
  
  
      // where you'll save the image
  
      $image  = BASE_PATH . "/public/uploads/image/" . "thumbnail-".$fileName .".jpg";
  
  
  
      // default time to get the image
  
      $second = 1;
  
  
  
      // get the duration and a random place within that
  
      $cmd = "$ffmpeg -i $video 2>&1";
  
      if (preg_match('/Duration: ((\d+):(\d+):(\d+))/s', `$cmd`, $time)) {
  
          $total = ($time[2] * 3600) + ($time[3] * 60) + $time[4];
  
          $second = rand(1, ($total - 1));
  
      }
  
  
  
      // get the screenshot
  
      $cmd = "$ffmpeg -i $video -deinterlace -an -ss $second -t 00:00:01 -r 1 -y -vcodec mjpeg -f mjpeg $image 2>&1";
  
      `$cmd`;

• Timelapse from image files in subfolders using FFMPEG

  11 avril 2022, par user44109

  Is it possible to search for image files in subfolders using FFMPEG ? I'm creating a time lapse video file from jpegs and they are located in subfolders (for each recorded day).

  


  Here is my current code, which will work if I run it in the folder with the image files, but it will not work if I try to run it on the parent folder (the folder containing the subfolders).

  


  ffmpeg -framerate 50 -pattern_type glob -i '*.jpg' -c:v libx264 -pix_fmt yuv420p out3.mp4


  


  Edit : I also tried this after the suggestion from @kesh

  


  ffmpeg -framerate 50 -pattern_type glob -i '**/*.jpg' -c:v libx264 -pix_fmt yuv420p out3.mp4


  


  What happens with that one is that it will indeed find the files in the subfolder but it only seems to encode the contents of the first subfolder.

  


• FFMPEG command for audio file streaming [closed]

  29 février 2024, par Vigo

  I am trying to stream an audio file in mp3 format using the FFMPEG library to a remote computer, located on the same LAN as the sender. The command i used to stream at the sender is given below :

  



  ffmpeg -re -f mp3 -i sender.mp3 -ar 8000 -f mulaw -f rtp rtp://10.14.35.23:1234


  



  I got the below command on FFMPEG documentation page that generates audio and streams it to port number 1234 on remote computer

  



  ffmpeg -re -f lavfi -i aevalsrc="sin(400*2*PI*t)" -ar 8000 -f mulaw -f rtp rtp://10.14.35.23:1234


  



  I thought i had made relevant changes to this so that the mp3 streaming command will work, but only to know encounter the error which reads
  
"Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height"

  



  Can anyone tell me what is the wrong parameter here and how to rectify it ?
