• ffmpeg-python error, cannot load mp4 encoder

  19 août 2020, par tristan_jia

  This error came when I just try a simple demo from the page of ffmpeg-python :

  


  import ffmpeg
stream = ffmpeg.input('human_face.mp4')
stream = ffmpeg.hflip(stream)
stream = ffmpeg.output(stream, 'new_human_face.mp4')
ffmpeg.run(stream)


  


  And the output goes like :

  


  ...&#xA;Input #0, mov,mp4,m4a,3gp,3g2,mj2, from &#x27;human_face.mp4&#x27;:&#xA;  Metadata:&#xA;    major_brand     : isom&#xA;    minor_version   : 512&#xA;    compatible_brands: isomiso2mp41&#xA;    encoder         : Lavf58.49.100&#xA;  Duration: 00:00:12.45, start: 0.000000, bitrate: 742 kb/s&#xA;    Stream #0:0(und): Video: mpeg4 (mp4v / 0x7634706D), none, 256x256, 741 kb/s, 20 fps, 20 tbr, 10240 tbn, 10240 tbc (default)&#xA;    Metadata:&#xA;      handler_name    : VideoHandler&#xA;Automatic encoder selection failed for output stream #0:0.

  I think the most important log is :"Automatic encoder selection failed for output stream #0:0. Default encoder for format mp4 (codec mpeg4) is probably disabled or this build of ffmpeg does not include that codec. Please choose an encoder manually."

  


  I've reinstalled the ffmpeg package but the error remains.

• ffmpeg concat two video and add watermark after concating video give me blank mp4 file on server but in local working perfectly why ?

  22 février 2018, par Jinal Somaiya

  i have two video i want to concat them and then add watermark to them but after command run give me blank mp4 file on server but in local working perfectly and on server two video concat perfectly but after that code is not running.

  My code is as follows.

  $videoFileName = rand('111111', '999999').'_'.time().'.'.$request->file('video1')->getClientOriginalExtension();
  
      $intermediateVideo1 = rand('1111111', '9999999').'_'.time().'.ts';
  
      $intermediateVideo2 = rand('1111111', '9999999').'_'.time().'.ts';
  
      $concatVideoFileName = rand('111111', '999999').'_'.time().'.'.$request->file('video1')->getClientOriginalExtension();
  
  
  
      exec('ffmpeg -i '.$request->file('video1').' -c copy -bsf:v h264_mp4toannexb -f mpegts '.$intermediateVideo1);
  
      exec('ffmpeg -i '.$request->file('video2').' -c copy -bsf:v h264_mp4toannexb -f mpegts '.$intermediateVideo2);
  
      exec('ffmpeg -i "concat:'.$intermediateVideo1.'|'.$intermediateVideo2.'" -c copy -bsf:a aac_adtstoasc '.public_path('uploads/videos/'.$concatVideoFileName));
  
  
  
      exec('ffmpeg -i '.public_path('uploads/videos/'.$concatVideoFileName).' -i '.storage_path("assets/image/watermark.png").' -filter_complex "overlay" '.public_path('uploads/videos/'.$videoFileName));
  
  
  
  
  
      File::delete($intermediateVideo1);
  
      File::delete($intermediateVideo2);
  
      File::delete('uploads/videos/'.$concatVideoFileName);
  
  
  
      return response()->download(public_path('uploads/videos/'.$videoFileName));

• ffmpeg - how to use pipe with amovie parameter ?

  19 février 2018, par user1347009

  I am looking for a solution to overlay to mp3 files in which the longer one will be played in the background and the smaller one will continue to play like a loop with that.
  My current code is working without pipe :

  ffmpeg -i 'longer.mp3'  -filter_complex "amovie='small.mp3:loop=999'[s];[0][s]amix=duration=shortest" new.mp3

  This code works like a charm but what i want to achieve is this :

  curl "any-url-to-api-to-audio-file" | ffmpeg -i 'longer.mp3'  -filter_complex "amovie='pipe\:0:loop=999'[s];[0][s]amix=duration=shortest" new.mp3

  This code is not working and its giving me error as well,

  All i want to do is to overlay two audio files via command line in which 1st audio file will be longer and the second one will be smaller.
  The smaller one will be repeated like a loop till the longer one play.

  Please tell me how can i do that ?
