• Php and Mysql current video time duration using FFMPEG

  10 novembre 2014, par innovation

  I have one question about video time calculator.

  I am using this FFMPEG

  shell_exec("ffmpeg -i ../videos/$video_name.flv -f flv -s 320x240 ../videos/$video_name.mp4");
  
  shell_exec("ffmpeg -i ../video_images/$video_name.mp4 -vcodec png -ss 00:00:05 -s 360x288 -vframes 1 -an -f rawvideo ../video_images/$video_name.png");

  I want to add here to post total duration of the video.

  For example : I upload a video this video time 4:10 (4 minutes 10 seconds). I want to post it this time from table row.
  How can i do this anyone can tell me ?

• FFMpeg PHP Package getting Error when loading in Laravel Queue

  18 mars 2020, par Steve Rogers

  I have created a code on Laravel to add watermark to my video with ffmpeg package. This function is working perfectly in when working with controller.

  Due to time consuming task I move the code to Laravel queue system and it successfully dispatch to queues table. but when I run php artisan queue:work the code getting error like

   Alchemy\BinaryDriver\Exception\ExecutionFailureException: ffmpeg failed to execute command '/usr/bin/ffmpeg' '-y' '-i' '/home/forge/demosite/public/frontend/video/1276841041584344642.mp4' '-threads' '12' '-vcodec' 'libx264' '-acodec' 'libmp3lame' '-b:v' '1000k' '-refs' '6' '-coder' '1' '-sc_threshold' '40' '-flags' '+loop' '-me_range' '16' '-subq' '7' '-i_qfactor' '0.71' '-qcomp' '0.6' '-qdiff' '4' '-trellis' '1' '-b:a' '256k' '-ac' '2' '-pass' '1' '-passlogfile' '/tmp/ffmpeg-passes5e6f2f04cec372bg0z/pass-5e6f2f04cecc2' '/home/forge/demosite/frontend/posts/video/org-post/n-w-post-video-org/17957037231584344836.mp4' in /home/forge/demosite/vendor/alchemy/binary-driver/src/Alchemy/BinaryDriver/ProcessRunner.php:10

  In many references I can see that this issue related to permission issue of public folder. so I give 777 permission to public folder and it will not working...

  Working Code..

     $ffmpeg = FFMpeg\FFMpeg::create([
  
          'ffmpeg.binaries'  => '/usr/bin/ffmpeg',
  
          'ffprobe.binaries' => '/usr/bin/ffprobe' ,
  
          'timeout' => 3600, // The timeout for the underlying process
  
          'ffmpeg.threads' => 12, // The number of threads that FFMpeg should use
  
      ]);
  
      $video = $ffmpeg->open($this->file);
  
      $random = rand().''.time();
  
      $randomFileName = $random . ".$this->extension";
  
  
  
      /*-------------------------------original video----------------------------------------------*/
  
      $format = new FFMpeg\Format\Video\X264('libmp3lame', 'libx264');       
  
      $format->setKiloBitrate(1000)->setAudioChannels(2)->setAudioKiloBitrate(256);

• FFmpeg : Get better encoding out of my function

  31 octobre 2019, par A Person

  I needed some assistance on my task.

  I am using FFmpeg to burn time and the channel name onto the video.

  My goal is to record a stream that is html5 compatible with the following settings :

  Video wrapper MP4

  Video codec H.264

  Bitrate 1Mbps

  Audio codec AAC

  Audio bitrate 128Kbps

  And GPU encoding.

  This is what I am using :

  ffmpeg -hwaccel cuvid -y -i {udp} -vf "drawtext=fontfile=calibrib.tff:fontsize=25:text='{ChannelName} %{localtime}': x=10: y=10: fontcolor=white: box=1: boxcolor=0x000000" -pix_fmt yuv420p -vsync 1 -c:v h264_nvenc -r 25 -threads 0  -b:v 1M -profile:v main -minrate 1M -maxrate 1M -bufsize 10M -sc_threshold 0 -c:a aac -b:a 128k -ac 2 -ar 44100 -af "aresample=async=1:min_hard_comp=0.100000:first_pts=0" -bsf:v h264_mp4toannexb -t 00:30:00 {output}\{ChannelName}\{ChannelName}_{year}_{monthno}_{day}__{Hours}_{Minutes}_{Seconds}.mp4

  {ChannelName}_{year}_{monthno}_{day}__{Hours}_{Minutes}_{Seconds} are all variable holding information.

  {udp} holds the UDP stream link.

  I have done it this way as I have multiple UDP stream recording.

  Although this works, is there a better way for me to do this keeping in the -vf as I need the time and channel name.

  Currently, this uses between 0.8% to 1.9% GPU on my Quadro P4000. I don’t want to use more than this as I have more than 30 streams.
