• PHP-FFMpeg filters()->resize() throw Use of undefined constant RESIZEMODE_INSET

  17 avril 2017, par Angus Simons

  I’m using PHP-FFMpeg to use FFMpeg with php, unfortunately I can’t set resize filter.

  This is my code :

  $video = $ffmpeg->open('video.mov');
  
  
  
  $dimension = new FFMpeg\Coordinate\Dimension(1920, 1080);
  
  $video->filters()
  
        ->resize($dimension, RESIZEMODE_INSET, true, 1)
  
        ->synchronize();
  
  
  
  $format = new FFMpeg\Format\Video\X264('aac', 'libx264');
  
  $format->setAudioChannels(2)->setAudioKiloBitrate(256);
  
  $video->save($format, 'video.mp4');

  But it throws this error :

  Use of undefined constant RESIZEMODE_INSET - assumed 'RESIZEMODE_INSET'

  I tried also :

  ->resize($dimension, 'RESIZEMODE_INSET', true, 1)

  and

  ->resize($dimension, 'inset', true, 1)

  But I can’t get the video converted without stretching.

  Thanks in advance

• Why ffmpeg launched on a google cloud function can throw "Error : Output stream error : Maximum call stack size exceeded" ?

  15 décembre 2020, par Stepan Shilin

  I'm trying to process video files with ffmpeg running on google cloud functions. Video files are downloaded from a google file storage, processed in stream by fluent-ffmpeg and streamed to a new google storage file. It works on smaller files but throws an "Output stream error : Maximum call stack size exceeded" on larger files.

  



  I tried running the code on a normal pc, and I haven't encountered this error, even with larger files.

  



  These are the parameters I deploy the function with

  



  gcloud functions deploy $FUNCTION_NAME --runtime nodejs8 --trigger-http --timeout=180 --memory 256


  



  This is the code that processes video

  



  function cutVideo({videoUrl, startTime, duration, dist}) {
    return ffmpeg(videoUrl)
    .outputOptions('-movflags frag_keyframe+empty_moov')
    .videoCodec('copy')
    .audioCodec('copy')
    .format('mp4')
    .setStartTime(startTime)
    .setDuration(duration);
}

const sectionStream = cutVideo({
    videoUrl,
    startTime,
    duration,
    dist: tempFilePath,
});

const outputStream = bucket.file(sectionPath)
.createWriteStream({
    metadata: {
        contentType: config.contentType,
    },
    public: true,
});


  



  Actual error stack looks like this

  What could cause this error on a google cloud function ?
