• aacenc : treat unknown profile as AAC-LC

  aacenc : treat unknown profile as AAC-LC
  When the encoder is ran without specifying -profile:a
  
  the default avctx->profile value is -99 (FF_PROFILE_UKNOWN),
  
  which used to be treated as AAC-LC.

• FFmpeg buildpack for Heroku does not support ogg. Unknown encoder 'libvorbis'

  3 octobre 2015, par Matthew Slaton

  After some work, I was finally able to get the buildpack installed on Heroku. I ran into this error :

  Stream #0:0: Audio: pcm_u8 ([1][0][0][0] / 0x0001), 22050 Hz, mono, u8, 176 kb/s
  
  
  
  2015-10-03T01:15:59.635036+00:00 app[web.1]: -t is not an input option, 
  
      keeping it for the next output; consider fixing your command line.
  
  2015-10-03T01:15:59.635055+00:00 app[web.1]: Please use -q:a or -q:v, -qscale is ambiguous
  
  2015-10-03T01:15:59.635479+00:00 app[web.1]: Unknown encoder 'libvorbis'

  My code is :

  ffmpeg -t 15 -i #{current_path} -acodec libvorbis -qscale 1 #{temp_path}

  The -t option is supposed to be for seconds and libvorbis is for ogg conversion.

  ffmpeg -version returns this :

  What am I doing wrong ?

• PHP and FFMPEG advice/sollution for a unknown issue

  20 octobre 2015, par sonam Sharma

  I am having a live video streaming website and I allow people to upload all the video files to the site till now everything is ok.

  What I am doing is that I am using FFMPEG to convert the video to mp4 and also get a image out of the video after 20 seconds.

  The code that I am using is that :

   require 'vendor/autoload.php';
  
          $getEXT_check=substr(@$_FILES['profileimage99']['name'],-3);
  
          if($getEXT_check !='mp4' && $getEXT_check !='MP4'){
  
          exec('ffmpeg -i '.$uploadfile.' -f mp4 -s 896x504 '.$new_flv.''); }
  
          //execute ffmpeg and create thumb
  
          exec('ffmpeg  -i '.$uploadfile.' -ss 00:00:20 -vframes 1  '.$new_image_path);
  
          $theduration=exec('ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 '.$uploadfile.' 2>&1');
  
          $theduration_val=round($theduration/60, 2);

  What issue I am having is that

  1. sometimes the code dosent extract the image out of video
  2. video conversation takes very long time for non mp4 video (I am not converting mp4 videos)

  Some info what I have done on server. During the development of site I installed ffmpeg on my pc and downloaded the vendor directory by composer.json file. But I have not done these things on my server I have a dedicated server from bluehost and have ffmpeg installed at this location.

  /usr/local/bin/ffmpeg
  
  /usr/local/bin/mplayer
  
  /usr/local/bin/mencoder
  
  /usr/bin/flvtool2
  
  /usr/local/bin/MP4Box
  
  /usr/local/bin/yamdi

  During uploading the site what I did is that I also uploaded the vendor directory and all the files and made the site live. I haven’t used any of the path as given by my server admin after asking.

  Please suggest me something where I am doing wrong.
