• How to optimize FFMPEG/ Editing video ?

  6 mars 2016, par user6964

  I have the next commands for editing video but all the process take a long time. But with the same quality of the original video.

  //First cut original video
  
  exec("ffmpeg -i $video_path_main -ss $first_time1 -t $first_time2 -s 476x268 -r 10 -b 2000k -r 30 -g 100 -ar 22050 -ab 48000 -ac 1 -strict -2 $name_first");
  
  exec("ffmpeg -i $video_path_main -ss $second_time1 -t $second_time2 -s 476x268 -r 10 -b 2000k -r 30 -g 100 -ar 22050 -ab 48000 -ac 1 -strict -2 $name_second");
  
  
  
  $name_edit_second = uniqid() . '.mp4'; //Then editing the second video
  
  exec("ffmpeg -i $name_second -s 476x268 -r 10 -b 2000k -r 30 -g 100 -ar 22050 -ab 48000 -ac 1 -strict -2 -vf movie='" . $image_name . " [watermark]; [in] [watermark] overlay=308:43"."' $name_edit_second");
  
  
  
  //Then merge video file mp4 with Mencoder
  
  $name_total_1 = uniqid() . '.mp4';
  
  exec("mencoder -oac pcm -ovc xvid -vf scale -xvidencopts bitrate=460 -o $name_total_1 ".$name_first.' '.$name_edit_second);
  
  
  
  //Then convert the video to 3 formats that is necessary in my Player.
  
  $name_total = uniqid();
  
  
  
  //Of MP4 a FLV
  
  exec("ffmpeg -i $name_partial -f flv -s 476x268 -r 10 -b 2000k -r 30 -g 100 -ar 22050 -ab 48000 -ac 1 $name_total.flv");
  
  
  
  //Of MP4-Mencoder a MP4-FFMPEG
  
  exec("ffmpeg -i $name_partial -s 476x268 -r 10 -b 2000k -r 30 -g 100 -ar 22050 -ab 48000 -ac 1 -strict -2 $name_total.mp4"));
  
  
  
  //Of MP4 a WEBM
  
  exec("ffmpeg -i $name_partial -acodec libvorbis -s 476x268 -r 10 -b 2000k -r 30 -g 100 -ar 22050 -ab 48000 -ac 2 -f webm $name_total.webm");

  I don’t know if some of parameters take much time for all the process. Or if one of this command take much time.

  Note : Some videos have more than 2 parts of their original videos.

  ---

  UPDATE

  Maybe the parameter -theards 1 help me in NO take a lot of resources of the CPU. Also, I need to optimize the re-encoding because with only 8 users take the 100% of resources.

  I run FFMPEG in a other server that return the video edited to other server where stay my application.

  Sorry for my english.
