  • How to create thumbnails of videos with Meteor, CollectionFS, & FFMPEG

    29 juin 2017, par Jared Martin

    I’m using Meteor with CollectionFS to store videos. I need a transform to create thumbnails of my videos.

    Videos = new FS.Collection("videos", {
    
  stores: [
    
    new FS.Store.FileSystem("thumbs", { 
    
      transformWrite: function(fileObj, readStream, writeStream) {
    
        // What goes here?
    
      }
    
    }),
    
    new FS.Store.FileSystem("videos"),
    
  ],
    
});

    I’ve worked out how to do this with ffmpeg :

    ffmpeg -i video.mp4 -vf  "thumbnail,scale=640:360" -frames:v 1 thumb.png

    But I’m not sure how to do this with the readStream I’m given and output the writeStream.

    Here’s an example of how it is done with images using GraphicsMagick :

    Images = new FS.Collection("images", {
    
  stores: [
    
    new FS.Store.FileSystem("thumbs", { 
    
      transformWrite: function(fileObj, readStream, writeStream) {
    
        // Transform the image into a 10x10px thumbnail
    
        gm(readStream, fileObj.name()).resize('10', '10').stream().pipe(writeStream);
    
      }
    
    }),
    
    new FS.Store.FileSystem("images"),
    
  ],
    
});

    Although the samples use the local filesystem, Ill be using cvs:dropbox, so you can’t rely on the file being there locally.

  • concatenate mp4 videos with ffmpeg concat demuxer in android

    6 mai 2016, par Ara Badalyan

    I want to concatenate mp4 videos with ffmpeg, the problem is when I want to merge videos taken with Iphone and Android it throws problem

    " Non-monotonous DTS in output stream 0:1 ; previous : 150528, current : 139268 ; changing to 150529. This may result in incorrect timestamps in the output file."

    This is my code

    merge.txt

    file 'iphone.mp4'
    
file 'android.mp4'

    ffmpeg command

    ffmpeg -f concat -i marge.txt -c copy -y merge.mp4

    If I can’t merge this videos how can i make them with same parameters (frame rate, bitrate...) and merge them ?

    P.S I use ffmpeg version 2.4.2 , because I can’t find android ffmpeg library higher then 2.4.2.
