  I want to add tags to mp3 converted by youtube-dl & ffmpeg :

  


  


  youtube-dl -o
'/Output/qpgTC9MDx1o.mp3' qpgTC9MDx1o -f bestaudio —extract-audio —metadata-from-title "%(artist)s -
%(title)s" 2>&1

  


  


  I have this error in the output result :

• Detect rotation angle and rotate final video using ffmpeg version 2.8

  9 novembre 2017, par Hemant Kumar

  I used to work on ffmpeg 2.2 until now and was detecting rotation angle of video uploaded from android / iPhone mobiles and rotate the resulting video so that it run perfectly on a correct angle.

  But since I have updated the ffmpeg to version 2.8 I am getting this rotation problem. My queries are not rotating the videos as they were earlier.

  Here’r the commands I was using :

  To check rotation angle :

  ffprobe -of json -show_streams {$input} | grep rotate

  below is my final command to convert a video to mp4

  "ffmpeg -i {$input} -strict -2 -vcodec libx264 -preset slow -vb 500k -maxrate 500k -bufsize 1000k -vf 'scale=-1:480 ".fix_video_orientation($input)."' -threads 0 -ab 64k -s {$resolution}  -movflags faststart -metadata:s:v:0 rotate=0 {$output}";

  "fix_video_orientation" function is given below. It detect the angle of rotation of the initial video and output optimal option for rotating the final video.

  function fix_video_orientation($input){
  
  
  
  $return= ", transpose=1 ";
  
  
  
  $dd= exec("ffprobe -of json -show_streams  {$input}   | grep rotate");
  
  
  
  if(!empty($dd)){
  
  
  
  $dd=explode(":",$dd);
  
  $rotate=str_replace(",","",str_replace('"',"",$dd[1]));
  
  
  
  if($rotate=="90")return $return;
  
  
  
  else if ($rotate=="180") return ", transpose=2,transpose=2 ";
  
  
  
  else if($rotate == "270") return ", transpose=2 ";
  
  }

  Currently above script is supporting "flv","avi","mp4","mkv","mpg","wmv","asf","webm","mov","3gp","3gpp" extensions, also the script is supporting the resulting .mp4 file to play on all browsers and devices.

  Now the ffprobe command is not returning rotation angle and so a portrait video if uploaded from iphone is showing as landscape on the website.

  Output console of ffprobe command :

  If latest version of ffmpeg (2.8) is used to auto rotate the video, can you please suggest me what option I need to add or remove from my final command.

  16 décembre 2017, par Stojan Kukrika

  I am trying to convert animated GIFs to MP4 files using ffmpeg. Only this convert GIF to MP4 :

    exec('ffmpeg -i ' . $destinationPath . $filename . ' -movflags faststart -pix_fmt yuv420p -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" ' . $destinationPath . $newFilename);

  And I can play it in my pc when download it from server, but it’s didn’t want to pay in browser. Browser returns me this error :
  

  After that GIF to MP4 converor I get one image for thumbnail image and that is works fine :

  exec("ffmpeg -i " . $destinationPath . $video . ".mp4 -ss  00:00:01.000 -vframes 1 ".storage_path().$folderNameThumb."/media.png");

  and it’s shows me a valid frame of GIF. Can anybody help me how to fix this problem with video ?

  Because I use Laravel this is method for return media :

  public function getGifImage(Media $media)
  
  {
  
      $path = storage_path() . '/uploads/gif/' . $media->content;
  
      if (file_exists($path)) {
  
          return response()->download($path, null, [], null);
  
      }
  
  }
