• ffmpeg image + audio to video, file size is very large ?

  10 juin 2019, par Hoopes

  I have a single image and a single audio file, and I’m trying to combine them into a video. The image is 186k and the audio is 242k, and the resulting mp4 file is 928k. Is this just one of those "Yeah, that’s how that works", or can I do something to make the resulting video file smaller with my ffmpeg command ? I’d like my output to be h264 video, and the audio to have the same quality as the input. The image in the video should ideally be as high quality as the input.

  My command is :

  ffmpeg -loop 1 -i image.jpg -i audio.mp3 -c:v libx264 -tune stillimage -c:a mp3 -b:a 192k -pix_fmt yuv420p -shortest result.mp4

  Are there any interesting flags I’m missing, or using any of those flags incorrectly ? If the input file is m4a, do I still need to use mp3 for an mp4 file ?

  Any help is very much appreciated, thanks !

• ffmpeg to hls not running correctly with error :Uncaught RangeError : Source is too large

  4 juillet 2019, par Mohsen Rahnamaei

  I want to add watermark in each video file which produce from hls server.
  inorder to do that I am using fluent ffmpeg js componnent.
  and this is my backend code of hls server

   self.provider.getSegmentStream(req, function (err, stream) {
  
  
  
  
  
  
  
  res.setHeader('Content-Type', CONTENT_TYPE.SEGMENT)
  
  res.statusCode = 200
  
  var proc = ffmpeg(req.filePath). videoFilters(
  
   {
  
  filter: 'drawtext',
  
  options: {
  
    text: 'VERY LONG TEXT VERY VERY VERY VERY LOL!!!',
  
    fontsize: 36,
  
    fontcolor: 'white',
  
    x: '(main_w/2-text_w/2)',
  
    y: '(text_h/2)+15',
  
    shadowcolor: 'black',
  
    shadowx: 2,
  
    shadowy: 2
  
  }}
  
  
  
   ) 
  
  
  
  .videoCodec('libx264')
  
  
  
   .audioBitrate('128k')
  
  
  
   .audioCodec('aac')
  
  
  
  .format('mpegts')
  
  .on('end', function(stdout, stderr) {
  
  console.log('Transcoding succeeded !',req.filePath);
  
  
  
  })
  
  
  
  .on('error', function(err) {
  
   console.log('an error happened: ' + err.message);
  
   }).pipe(res ,{end:true})

  and in my client i am using this code :

  if(Hls.isSupported())
  
  {
  
    console.log('hls is suported');
  
      var video = document.getElementById('video');
  
      var hls = new Hls();
  
      hls.loadSource('http://serverip:8182/streams/stream.m3u8');
  
      hls.attachMedia(video);
  
      hls.on(Hls.Events.MANIFEST_PARSED,function()
  
      {
  
          video.play();
  
      });
  
  }
  
  else if (video.canPlayType('application/vnd.apple.mpegurl'))
  
  {
  
    console.log('hls isnot suported');
  
  
  
      video.src = 'http://serverip/streams/stream.m3u8';
  
      video.addEventListener('canplay',function()
  
      {
  
          video.play();
  
      });
  
  }

  but i have problem becaus its just play first ts file but after that hls has stoped and in console i get this error :
